DESC:FIELD OF THE INVENTION

[001] The present invention relates generally to electrical distribution systems, and more particularly to feeder pillar boxes installed along pathways or indoors spaces.

BACKGROUND OF THE INVENTION

[002] A feeder pillar box is a cabinet for electrical equipment, mounted in the street and controls the electrical supply to a number of houses of the neighborhood. The feeder pillar box (also referred as ‘feeder pillar or power box’) includes busbar connections, fuses in an enclosure used in conjunction with underground electrical distribution cables, sensors, switches etc. Feeder pillar boxes (FPBs) are provided in two categories namely Main Feeder pillar and Mini (Service) feeder pillar. The Main FPB is connected directly with a distribution transformer and pluralities of Mini FPBs are connected to the Main FPB. The Mini FPBs supply power to the consumer location.

[003] There are basically two types of feeder pillar boxes: horizontal type and vertical type based on the arrangement of fuses in the box. The electric fuse is a device that is used to protect electric circuits and electric appliances against high current caused by short - circuiting or overloading due to passage of large current. A fuse is a short piece of wire made of a material of high resistance and low melting point, such that it melts when too much current flows through it, thereby interrupting the current. It is a sacrificial device and once a fuse has operated it is an open circuit, and it must be replaced or rewired.

[004] Sometimes circuit breakers may be used in the feeder pillar boxes instead of fuses to serve the same purpose. However considering the cost, simplicity and speed of action, fuses are preferred over the circuit breakers.

[005] In case of horizontal type boxes, all three fuses of three different live phases R,Y,B are arranged on top of each other in a vertical line. The fuse housing of such horizontal type boxes are configured to be disconnected as one single phase or all three phases in a single disconnecting action.

[006] In vertical type feeder pillar boxes, the fuses of different phases are arranged side by side to each other and it’s is difficult to operate all phase fuses in one pull of the fuse holder.

[007] The feeder pillar boxes are installed near streets on the footways, indoors for industry and household supplies. The problem with presently available feeder pillar boxes is the space occupied by them on the footway, which obstructs movement of people partially. It is constant need to have a feeder pillar box which occupies least possible footprint at the place of installation.

[008] Further the currently available feeder pillar boxes are designed as conventional rectangular boxes with busbars and fuses mounted inside the box. The poor thermal design, arrangement of fuses and busbars adds to the size of the box and increases the footprint area occupied by the feeder pillar. The currently available feeder pillars have several problems during installation and servicing. The live busbars are accessible when feeder pillar door is opened and may cause threat to the life of the person attending any fault or during installation of the feeder pillar.

[009] The feeder pillar is installed on streets also, so it has to withstand the harsh environment such as rains, dust and dirt. Currently available feeder pillar box designs do not address the Ingress Protection very efficiently. Besides this, there are issues of theft of power or internal components by tampering the enclosure door of the feeder pillar box.

[0010] In addition, the currently available FPBs are not technically efficient and lead to high I2R losses due to poor contact between the conductors and busbars. Poor heat dissipation also happens owing to poor design of the enclosure and layout of busbars/ fuse arrangements.

[0011] In view of the limitations inherent in the available feeder pillar boxes, there exists a need for an improved feeder pillar box which overcomes the disadvantages of the prior art and which can be manufactured in a cost effective, reliable, secure and environmental friendly manner.

[0012] The present invention fulfils this need and provides further advantages as described.

[0037] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without these specific details.

[0038] As used herein, the term ‘plurality’ refers to the presence of more than one of the referenced item and the terms ‘a’, ‘an’, and ‘at least’ do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced item.

[0039] Reference herein to “one embodiment” or “another embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Further, the diagrams representing one or more embodiments of the invention do not inherently indicate any particular order nor imply any limitations in the invention.

[0040] Referring to FIG. 1, that illustrates a schematic diagram of an inside view of a feeder pillar box 10, according to one embodiment of the present invention. The feeder pillar box 10 comprises a hexagonal base 12, at least one fuse panel 14 mounted vertically on the hexagonal base, a plurality of outgoing connection fuses 16 installed on the fuse panel, a plurality of incoming connection fuses 18 installed on the hexagonal base and an enclosure 20 (not shown) for enclosing all components of the feeder pillar box.

[0041] In one embodiment of the present invention, the fuse panel 14 has an L-shaped cross section with a first side 14a and a second side 14b making an angle with each other. The L-shaped cross section extends longitudinally to form one fuse panel 14. In one embodiment of the present invention, the feeder pillar box 10 includes three fuse panels 14 representative of three live electrical phases, each one for a live phase viz: R, Y and B. In an alternative embodiment of the present invention, the feeder pillar box 10 may include four fuse panels 14, such that three fuse panels are representative of three live electrical phases R, Y, B and and a fourth fuse panel 14 is representative of a neutral phase.

[0042] Referring to FIGs. 2A and 2B, that illustrates schematic diagrams of the front and back side respectively of the fuse panel 14, according to one embodiment of the present invention. The fuse panel 14 includes a plurality of fuse holders 22 mounted on a front side of the fuse panel, a main busbar 24 (also shown in FIG. 3) mounted on the front side of the fuse panel 14 and a plurality of tapping busbars 26 mounted on the back side of the fuse panel 14. The front side shows the arrangement of fuses 16 on the fuse panel 12 and the back side shows the tapping busbars 26 each connected with respective fuse.

[0043] Each fuse holder 22 is configured to receive the outgoing connection fuses 16. The fuse holder 22 design is customized as per the design and dimensions of the connection fuse to be used. The top portion of each of the fuse holder 22 is electrically connected with the main busbar 24 on the front side of the fuse panel and a bottom portion of the fuse holder 22 is connected with corresponding tapping busbar 26 at the back side of the fuse panel.

[0044] The main busbar 24 is adapted to electrically connect with each of the outgoing connection fuse 16. The main busbar 24 provides the incoming power connection and is connected electrically with each and every fuse on the panel 14. In one embodiment of the present invention, the main busbar 24 is covered in an insulated coating to prevent any contact with live electrical part by any person.

[0045] The tapping busbars 26, located at the back side of the fuse panel 14 are smaller cross section busbars used for electrically connecting the individual outgoing connection fuses 16 with their respective outgoing connection wires. Each of the outgoing connection fuse 16 has an independent tapping busbar 26 associated with it.

[0046] In one embodiment of the present invention, each of the plurality of tapping busbars 26 comprises a fuse end 26F and a wire end 26W, such that the fuse end 26F is connected with the outgoing connection fuse 16 and the wire end 26W is connected with the outgoing connection wire of the fuse through plugin connectors or lugs. As can be seen that in FIG.2B, the tapping busbars 26 are arranged, such that they do not touch each other and are bent and orientated with each other to occupy least space and maintain the electrical clearance between the busbars 26. Mounting the tapping busbars 26 behind the fuse panel 14 makes them inaccessible, thereby preventing any damage and assure complete human safety by accidental human touch. Further the tapping busbars 26 are designed and located to have better thermal cooling by natural convection.

[0047] In one preferred embodiment of the present invention, the wire end 26W of each of the plurality of tapping busbars 26 is located at the same level in the hexagonal base 12. The connections from the wires can be made with the wire end 26W of all the tapping busbars 26 at same location. The incoming and outgoing connection wires are also arranged in the hexagonal base 12. This assures termination of all the outgoing connections at the same level, thereby making the installation and maintenance easier. It makes easy for an operator to make connections at the ground level from the hexagonal base 12 and there is no need to disturb the busbars on the fuse panel 14.

[0048] Referring to FIG. 3, that illustrates a schematic diagram of the fuse panel 14 showing fuse housing 32 and main busbar 24, according to one embodiment of the present invention. A plurality of fuse housings 32 are provided for containing each of the plurality of outgoing connection fuses 16 and the plurality of incoming connection fuses 18. As can be seen, fuse housings 32 are provided on each of the fuses. The main busbar 24 extends from the hexagonal base 12 to the fuse panel 14 connecting the live phase wire with its corresponding fuse panel. A SFU (Switch Fuse Unit) is also provided for multiple connection and disconnection of fuses.

[0049] In one embodiment of the present invention, the plurality of outgoing connection fuses 16 may be mounted on one of the first side 14a and the second side 14b of the fuse panel as shown in FIG.1. In another embodiment, the plurality of outgoing connection fuses 16 may be mounted on a combination of the first side 14a and the second side 14b of the fuse panel. In yet another embodiment, the plurality of outgoing connection fuses 16 may be mounted on a common edge of the first side 14a and the second side 14b of the fuse panel.

[0050] The three fuse panels 14 may be arranged facing back to back with each other and mounted on the hexagonal base 12 to form the feeder pillar box 10 of the present invention. The three fuse panels 14 are held on the hexagonal base 12 by inserting them in slots in the hexagonal base 12 and are further held in position by the enclosure 20. Further nuts and bolts or any other fixtures, fastening devices may be used for holding the fuse panels 14. Whenever needed, the panels 14 may be detached from the hexagonal base 12. This makes the feeder pillar box 10 modular and can be used for one phase, two phase or as per the needs of the utility company.

[0051] In one embodiment of the present invention, the fuse panels 14 may be made of any insulating material such as ebonite, plastic, Bakelite, FRP (Fibre Reinforced Plastic) or any similar material known in the art which provides strength and electrically & thermal insulating properties needed for the feeder pillar box construction and its respective components.

[0052] Referring to FIG. 4, that illustrates a schematic diagram of the hexagonal base 12, according to one embodiment of the present invention. The hexagonal base 12 is formed of six faces 34, each including a fuse holder 36 and a bridge bar 38, such that the fuse holder 36 is adapted to receive an incoming connection fuse 18 and the bridge bar 38 electrically connects two corresponding incoming connection fuses 18 having same live phase with each other. The hexagonal base 12 of the feeder pillar box acts as a housing for some components of the feeder pillar box 10 and also provides structural support to the three fuse panels 14.

[0053] In one preferred embodiment of the present invention, there are two incoming connection cables which are provided with two sets of R, Y, B wires, so total six live phase connections are made as input to the corresponding six incoming connection fuses 18. Each of the face 34 of the hexagonal base 12, further includes fuse holders 36 and bridge bars 38. The bridge bars 38 connect two corresponding fuses sharing same live phase with each other. For example, the R wire from both the incoming cables may be connected to a couple of fuses connected by bridge bars, so both the fuses are R phase. The bridge bar 38 connects them electrically, so both are R phase. Similarly it may be done for Y and B phase wires. The set of fuses representing a particular phase (say R) are connected by the main busbar 24 to corresponding fuse panels 14 in the feeder pillar box. The incoming connection wires end in base and main busbar 24 is used to connect the phase wires with the fuses.

[0054] Each of the fuse panel 14 is configured to represent a single live phase and include number of fuses as per the requirement of feeder pillar box. There may be two to twelve number of outgoing connection fuses 16 of a single phase on a fuse panel 14 as per the needs of the feeder pillar box 10 rating. Design is flexible i.e. the footprint can be varied with respect to the arrangement of fuses.

[0055] Referring to FIG. 5, that illustrates a view of the feeder pillar box with hexagonal base 12 in open position, according to one embodiment of the present invention. In one embodiment of the present invention, the hexagonal base 12 includes hinged connections about alternate edges of the six faces 34, thereby making it adaptable to be opened from three sides. All components inside the hexagonal base 12 are accessible by opening the hinged doors. This provides ease of installation and maintenance activities to be performed when needed.

[0056] In one embodiment of the present invention, the feeder pillar box 10 further includes a neutral block(not shown) located in the hexagonal base 12 for connecting a plurality of neutral connection wires with each other. The neutral block comprises of a solid metallic block having a plurality of connection holes for inserting the neutral connection wires. In one preferred embodiment of the present invention, the neutral block is coated with a polymeric insulating material to avoid electrical contact with other components in the hexagonal base.

[0057] In one embodiment of the present invention, the hexagonal base 12 may be made of any insulating material such as ebonite, plastic, Bakelite, FRP (Fibre Reinforced Plastic) or any similar material known in the art which provides strength and insulating properties needed for the feeder pillar box construction.

[0058] The tapping busbars of six outgoing fuses are also divided into two sets of three tapping busbars on back of first and second side of the fuse panel.

[0059] In a preferred embodiment of the present invention, the incoming connection fuses 18 are mounted on the hexagonal base 12, however in another embodiment, the incoming connection fuses 18 may also be mounted on the fuse panels. In such cases the hexagonal base 12 will only provide structural support to the fuse panels 14.

[0060] The present design of the feeder pillar box, further provides the adaptability to use only one or two fuse panels 14 instead of all three. For example where the requirement is of only for two phases, one of the fuse panel may be removed by detaching from the hexagonal base 12 and the feeder pillar box 10 may be used with only two fuse panels as shown in FIG.6.

[0061] Referring to FIG.7, that illustrates a schematic diagram the enclosure 20 of the feeder pillar box, according to one embodiment of the present invention. The enclosure 20 includes a hexagonal frame 40 and three detachable doors 42 to provide complete all round accessibility inside the feeder pillar box 10. The hexagonal frame 40 allows three doors 42 to be mounted on it, such that they can be opened as hinge doors and detached completely when needed. The doors 42 are V-shape cross section sheets which are hingedly connected to the frame 42 on one side and other side includes door locking mechanism. All the three doors 42 when opened provide complete all round accessibility to inside of the feeder pillar box 10, for performing any installation, repair or maintenance activities.

[0062] The enclosure 20 further includes arrangements to mount the fuse panels 14 on its desired position on the hexagonal base 12. The enclosure 20 is also provided with louvers for allowing circulation of air by natural convection, and keeping the temperature of enclosure 20 within acceptable limits. The louvers may also include a water arresting back plate which prevents any splash of water to go inside the enclosure 20. The arrested water is accumulated from the back plate at the bottom and drained outside from the enclosure 20. A drainage pipe may also be provided to drain the accumulated water outside the enclosure 20. The shape and size of louvers is designed based on the heat produced as per the rating of the feeder pillar box. The enclosure 20 also include thermal windows for example a mesh which is adapted to only allow air to pass through but not dust or any other things.

[0063] The enclosure 20 is designed with additional space of 10 cm to 12 cm over the space required to contain the fuse panels for installation of any other component such as remote monitoring box. The enclosure 20 further is adapted to be scaled to include bigger size of fuse panels 14 as per the requirements of the feeder pillar box 10. Further additional features such as anti-theft locking system, shock proof may be included as per the requirements.

[0064] The enclosure 20 may be made of mild steel to provide greater strength to prevent any vandalism and designed for required Ingress Protection.

[0065] For installing the feeder pillar box 10, the hexagonal base 12 is mounted on a concrete foundation or a base plate, where the feeder pillar box has to be installed and the fuse panels 14 are mounted on the hexagonal base 12. The hexagonal base 12 may be mounted at a height above the ground allowing ventilation from bottom of the feeder pillar box 10. Now the incoming and outgoing cables coming from underground are inserted from bottom in the hexagonal base 12 of the feeder pillar box. The wires of the incoming cable are connected to the main busbars 24 and the outgoing wires are connected to the tapping busbars 26 using terminations, connectors or lugs. The neural wires of the incoming and outgoing wires are connected to the neutral block. Now the enclosure 20 is mounted to cover the whole structure.
