Description:TECHNICAL FIELD
[0001] The present disclosure relates generally to the field of electrical protection devices. More particularly, the present disclosure relates to the field of mounting wirelessly operated contact or non-contact temperature sensor on a bus bar. Specifically, the present disclosure relates to a system for temperature measurement of a bus bar.

BACKGROUND
[0002] The following description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Generally, with the recent electrical engineering and manufacturing developments, there has been an increased use of bus bars in almost every electric equipment, appliance or system. The bus bars are mostly used to carry high currents in any electrical system. This passage of high currents through the bus bars leads to a rapid and extreme over-heating of the bus bars. Such over-heating causes damage to a support structure of the bus bar, or a faulty operation of the electrical system, or sometimes completely shut down the electrical system or cause an irreparable damage to the electrical system.
[0004] Simultaneously, the electromagnetic forces generated due to the passing of high current, distort the softened conductors which may break free from their supports. Further, a higher working temperature also means that a lot of energy is being wasted in the electrical system.
[0005] Consequently, the continuous monitoring of the temperature of the bus bar becomes a necessity for predicting and preventing the advancing damages and for predicting when maintenance of the bus bar or a bus bar assembly needs to be performed. This preemptive and predictive approach ensures cost savings over routine or time-based precautionary maintenance, since maintenance tasks are performed only when warranted. Thus, predictive maintenance turns out to be the most effective tool to prolong the life and efficiency of any electrical system and minimize the shut-downs. Therefore, effective temperature monitoring of the bus bars or the bus bar assembly aids in ensuring the reliable operation and prolonged life of the bus bars and the electrical system.
[0006] As known in the conventional art, the passive wireless temperature sensor structures are generally used for bus bar temperature measurement. These passive temperature measurement structures may consist of a U-shaped metal component, with its one end provided with a screw hole that mounts a wireless or a surface wave temperature sensor with an antenna. The other end of the U-shaped metal component may be provided with a bolt for locking the bus bar. Further, in all such passive temperature measurement structures, the U-shaped metal component has certain elasticity and the wireless or the surface wave temperature sensor is fitted inside the screw hole, and the antenna is generally a long extending component beyond the body of the U-shaped metal component for achieve wireless signal transmission and reception.
[0007] The wireless or the surface wave temperature sensor and the antenna are commonly fitted to the U-shaped metal component by soldering or other welding process. Thus, such passive temperature measurement structures are entirely fixed to the bus bars.
[0008] However, such fixed passive temperature measurement structures itself cause damage to the bus bar or the bus bar assemblies. Further, these conventional passive temperature measurement structures are not efficient for any maintenance of the structure or the bus bar on which they are mounted. The temperature measurement efficacy is also reduced very soon due to such fixed arrangement. Thus, the conventional temperature monitoring or measurement of the bus bars does not effectively provide a system for the preventive and predictive temperature monitoring as well as maintenance of the bus bars.
[0009] There is therefore a need for a new, simple and compact system for temperature measurement and predictive temperature monitoring of the bus bars or the bus bar assemblies such that any harm or damage to the bus bar or the electrical system can be avoided and a proper and scheduled maintenance can be performed as and when required for a prolonged life of the bus bar as well as the electrical system.

Where a definition or use of a term in an incorporated reference is inconsistent or contrary to the definition of that term provided herein, the definition of that term provided herein applies and the definition of that term in the reference does not apply.

The partition of the enclosure 3 may be used to place the sensor system in the enclosure 3 above the level of the bus bar 1 such that a non-contact or wireless temperature sensor may be effectively used for measuring the temperature of the bus bar 1. The through hole 3a may facilitate an entry of the thermal radiation emitted by the bus bar 1 into the sensor circuit of the system 300.
[00067] Referring FIGs. 5(a) – 5(d), a plate clip 6 for the system 100 is illustrated in a side view 500a, a front view 500b, a perspective view 500c, and an isometric view 500d, respectively, in accordance with an exemplary embodiment of the present disclosure.
[00068] In a non-limiting example, the plate clip 6 may comprise a base 6a connected to a set of arms, a front arm 6b and a rear arm 6c. The front arm 6b may be an arm perpendicular to the base 6a (i.e., the front arm 6b forms a right angle with the base 6a) and the rear arm 6c may an arm connected to the base 6a and inclined towards the front arm 6b (i.e., the rear arm 6c forms an acute angle with the base 6a). The rear arm 6c may comprise an extended arm 6c' extending outwards away from the rear arm 6c (i.e., the extended arm 6c' forms a reflex angle with the rear arm 6c), as seen in FIG. 5a, 5c, 5d, and 6.
[00069] In an aspect, the plate clip 6 may further include a cavity 6d comprising screw threads for attachment of the enclosure 3. The cavity 6d may also comprise a locking end 6e for an effective locking of the enclosure 3 on the bus bar 1.

The system 600 for temperature measurement of the bus bar 1 comprises the bus bar 1, a plate clip 6, the enclosure 3, and the cover 4. The system 600 is identical to the system 100 with the only difference that the clamp 2 is replaced with the plate clip 6.
[00071] In an aspect, the plate clip 6 is a U-shaped clip that surrounds the bus bar 1 along the three adjacent sides of the bus bar 1 with the front arm 6b, the base 6a and the rear arm 6c. The plate clip 6 may be fixed to the bus bar 1 using a snap-fit or a press-fit arrangement without requiring any fastening means. The snap-fit arrangement is facilitated due to the inclined arrangement of the rear arm 6c comprising the extended arm 6c'.
[00072] In an exemplary embodiment of the present disclosure, the assembly 200 or 400 may be used for the bus bar 1 of any variable thickness. In an aspect, the bus bar 1 may comprise a thickness of upto 20mm, however, this thickness of the bus bar 1 may be more than 20mm as well depending on the requirement. Further, the assembly 200 or 400 may also be used for any orientation of the bus bar 1 in an electrical system.
[00073] In an embodiment of the present disclosure, the system 100, 300, or 600 comprises a control unit enabled to read or process the temperature of the bus bar 1 into a temperature data. The control unit further transmits the temperature data to a remote server or device over a wired or a wireless communication medium. The control unit may be a part of the sensor circuit embedded in the enclosure 3 of the system 100, 300, or 600.
[00074] In an exemplary embodiment of the present disclosure, the temperature sensor used in the sensor circuit of the disclosed system 100, 300, or 600 may be any generic temperature sensor of the type of a contact based or a non-contact based temperature. For example, an infrared (IR) temperature sensor is a non-contact based temperature sensor which comprises the ability to measure a temperature of an object (here, the bus bar) from a portion of the thermal radiation emitted by the object. This thermal radiation emitted by the object is also termed as a black-body radiation emitted by the object. The non-contact based temperature sensors are precisely efficient and have a wear-free impact on the object whose temperature is being measured. Further, a contact based temperature sensor is the one which is required to be in physical contact with the object whose temperature is being measured. Such temperature sensors use conduction methodology to monitor changes in the temperature of the object.
[00075] In another exemplary embodiment of the present disclosure, the system 100, 300, or 600 may further comprise a gasket to be placed in between the enclosure 3 and the bus bar 1. The gasket confirms a firm gripping of the enclosure of the assembly 200 or 400 onto the bus bar 1.
[00076] In an exemplary aspect of the present disclosure, the clamp 2, or the clip 5 or the plate clip 6, the enclosure 3 and/or the cover 4 may be formed of a metal or thermoplastic with high electrical and thermal resistance. In an aspect, the metal may include any metal or spring grade steels or the like. In another aspect, the thermoplastic may be any insulating thermoplastics including, but not limited to, polyamide (PA66) with or without filler materials, resin cast materials with or without fillers, thermoset materials like SMC (sheet moulding compound) or DMC (dough moulding compound) or the like.
[00077] It would be appreciated that although aspects of the present disclosure are explained with respect to a screwing arrangement of the enclosure 3 with the clamp 2, the clip 5, or the plate clip 6 and the cover 4, those skilled in the art would appreciate that, any other arrangement of a fastening or a fitting means may also be utilized for attachment of the enclosure 3 with the clamp 2, the clip 5, or the plate clip 6 and the cover 4, without departing from the scope of the present disclosure.
