, Description:TECHNICAL FIELD
[0001] The present disclosure relates generally to a field of electrical power distribution system. More specifically, it pertains to a safety system for plug-in points of busway that automatically covers plug-in points when plug-in box is not inserted in the plug-in points of busway.

BACKGROUND OF THE INVENTION
[0002] Background 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] A busway includes plurality of sheet metal ducts of either copper or aluminium used in electrical power distribution. The individual ducts can be easily electrically coupled with each other to obtain any desired length. In a plug-in busway, at least some of the sections are equipped with built-in electrical stabs adapted to receive plug-in units which are enclosures for attaching electrical devices to be connected to the busway. Plug-in busway is a type of busway where plug-in points are provided for insertion of plug-in box which typically consist of circuit breaker. Plug-in busways are adapted with plug-in box to tap off the power from the main conductors.
[0004] When plug-in box is not attached to the Plug-in points, then there should be some safety features configured with the Plug-in points to allow safety of operator from any electrical shock or electrical accident. Conventionally, the plug-in points are initially covered with cover which can be removed before inserting the plug-in box. Upon opening the plug-in cover, the plug-in points give access to conductors of plug-in box to engage with busways. Meanwhile, after the opening of plug-in cover and before engaging conductors of plug-in box, the plug-in points are exposed to environment directly. This gives access of body parts of operator and also there is possibility of entry of dust particles into plug-in points, thereby can cause reduction of insulation strength of busway. If the conductors of plug-in box are inserted in plug-in points as soon as plug-in point cover is removed, then the possibility of dust particles to enter in plug-in points can be reduced.
[0005] In an existing technology, the length of actuating means provided on plug in box is more than that of conductors in plug-in box. This causes actuators to interfere with the busway housing and do not allow plug-in box to get fully inserted into plug-in points. Hence, a slot is provided in existing busway housing so that actuator can pass through slot and plug in box can be fully inserted into plug-in points. These slots calls for unwanted manufacturing process and also may lead to ingress protection failure. Further, water can directly come in contact with plug-in busway which can be very harmful for electrical system and can cause severe accidents.
[0006] Another existing technology offers more number of components in the plug-in box which makes plug-in box and plug-in busways costly. The cost increases due to tooling, manufacturing, and assembly of extra components. Further, plug-in busway can be provided with hinged cover such that axis of rotation of hinged cover is perpendicular to length of plug-in busway, because of which hinged cover may interfere with next nearest plug-in box.
[0007] There is, therefore, a need in the art to provide a simple and cost effective safety system for busway that introduces automatic safety cover to plug-in points when plug-in box is not inserted in the plug-in points.

OBJECTS OF THE INVENTION
[0008] A general object of the present disclosure is to provide an efficient and economical solution for safety system of plug-in points of busway to avoid any accidental chances when plug-in points are uncovered.
[0009] An object of the present disclosure is to provide a simple and cost effective safety system for plug-in points of busway.
[0010] An object of the present disclosure is to provide a safety system for plug-in points of busway that automatically covers plug-in points when plug-in box is not inserted in plug-in points.
[0011] An object of the present disclosure is to provide a safety system for plug-in points of busway that provides equal length of conductors and actuating means of the plug-in box to avoid any need of extra slots in the plug-in busway.
[0012] An object of the present disclosure is to provide a safety system for plug-in points of busway that do not allow any accumulation of water and dust in proximity to the plug-in points and plug-in box.
[0013] An object of the present disclosure is to provide a safety system for plug-in points of busway comprising hinge cover which avoids any interference with nearest plug-in box.
[0014] Another object of the present disclosure is to provide a safety system for plug-in points of busway which avoids requirement of additional components in plug-in box and plug-in busway, thereby reducing any complexities in manufacturing.
[0015] These and other objects of the present invention will become readily apparent from the following detailed description taken in conjunction with the accompanying drawings.
