, Description:
TECHNICAL FIELD
[0001] The present disclosure relates to casings or enclosure or totally-enclosed installations, and more specifically relates to, a shroud assembly to protect plugin points of plugin feeders when not in use, from ingress of foreign object.

BACKGROUND
[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 distribution system is a system that distributes electrical power throughout a building. Distribution systems are used in every residential, commercial, and industrial building. A distribution system consists of metering devices to measure power consumption, main and branch disconnects, protective devices, switching devices to start and stop power flow, conductors, and transformers. Power may be distributed through various switchboards, transformers, and panel boards. Good distribution systems don’t just happen. Careful engineering is required so that the distribution system safely and efficiently supplies adequate electric service to both present and possible future loads. Commercial and industrial distribution systems use several methods to transport electrical energy. These methods may include heavy conductors run in trays or conduit. Once installed, cable and conduit assemblies are difficult to change. Power may also be distributed using bus bars in an enclosure. This is referred to as busway. Busway is defined by the National Electrical Manufacturers Association (NEMA) as a prefabricated electrical distribution system consisting of bus bars in a protective enclosure, including straight lengths, fittings, devices, and accessories. Busway (interchangeably referred as bus duct or ) is mainly used in large public buildings, high-rise buildings the supply and distribution system, the switch box is inserted for electrical power distribution busway system lead unit, which is inserted through the box pin row bus bar and the copper busbar tight junctions to achieve. Busway includes bus bars, an insulating and/or support material, and housing. Bus ducts are used in commercial and industrial settings, both indoors and outdoors.
[0004] A plug-in (as interchangeably referred to as “plugin”) bus duct system or busway can have disconnected switches and other devices mounted on it, for example, to distribute power along a long building. Many forms of busway allow plug-in devices such as switches and motor starters to be easily moved; this provides flexibility for changes on an assembly line. Feeder busway is used to interconnect equipment, such as between a transformer and a switchgear line up. A variant type is low-impedance busway, which is designed to have lower voltage drop by virtue of close spacing of bus bars, which reduces inductive reactance.
[0005] Plugin feeders are one of the most widely used accessories of busway systems for electricity distribution purpose. The electricity is tapped off from the plugin points provided at regular interval on plugin feeders with the help of plugin boxes which are facilitated with certain type of switchgear for switching and distribution network protection purpose. Plugin feeders are also termed as rising mains when installed in vertical orientation in multi floored premises. Plugin feeders of busways are installed in various orientations in such buildings. Plugin feeders of busway system can also be mounted in edgewise or flatwise orientation. Typically, busways are installed before interior and exterior work of building. At most of installation sites, busways are installed after completing slab work. Plastering and pointing, watering, plumbing, drilling for point fixing and painting work is carried out after busway installation. Plugin feeders provide plugin points for tapping off the electricity. These plugin points are a type of openings on plugin feeders with busbar offset at a certain pitch value where contact jaws of plugin boxes are inserted for supply tap off. Absence of a shroud or covering on these plugin points leads to a high possibility of ingress of foreign particles in busway system. Interference of foreign particle with live parts and insulation degrades its working capability and may lead to electrical faults. These plugin points being open slots in nature are shrouded for the purpose of preventing any ingress of foreign particles through these openings and can act as an obstruction for foreign particles to ingress inside busway system. These shrouds find their importance when the plugin boxes need to be mounted on these plugin points for supply distribution, these cover should be an integral part of the plugin feeders wherein on the event of plugin box maintenance/replacement activity the plugin points cannot be left uncovered which can endanger the working personnel’s life as the system may be in live condition. Moment the plugin boxes are removed these plugin points are required to be shrouded immediately, otherwise an unlikely event such as flashover may occur which can harm entire system and may lead to multiple hazards.
[0006] Efforts have been made in related art to address above stated problem by using an enclosure. An example of such enclosure is recited in a United States Patent 3710302A, entitled “Bus duct with hinged cover for plug-in region”. The patent discloses a section of plug-in type bus duct comprises a plug-in region at an opening in the housing of the duct. A plug-in insulating member, having opening means therein, is supported in the housing at the plug-in region. A plug-in cover is pivotally mounted on the insulating member to cover the opening means in the insulating member. The cover is formed with a resilient latch at the pivoted end thereof that cooperates with the housing to maintain the cover in the open position and another resilient latch at the opposite end thereof that cooperates with the insulating member to maintain the cover in the closed position. The parts are constructed such that the plug-in cover is captured on the insulating member when the insulating member is mounted in the housing.
[0007] However, the conventional enclosure or plug-in cover is complex in the development as well as handling. Further, in the conventional cover there is a requirement of additional space when the cover is open and plug-in unit is inserted. Furthermore, in the conventional cover or enclosure there is a less possibility of use of plug-in hole near to the joint section as additional space requirement to dispose the cover when plug-in point is in use. Additionally, in the conventional cover there is possibility of intersection of shroud when multiple plug-in holes are available on the busduct. Thus there are restrictions in takeout points for supply.
[0008] Whereas there is certainly nothing wrong with existing plug-in cover or cover, nonetheless, there still exists a need to provide an efficient, effective, reliable, and improved shroud assembly or shroud cover to protect plugin points of plugin feeders when not in use, from ingress of foreign object which if not done, may lead to potential hazards to both installation and premise as the plugin point openings are live in nature. Further there is also a need of a shroud assembly which does not necessitate additional space requirements while flaps are opened. Furthermore there is a dire need of shroud assembly for lifelong protection of plugin points, no possibility of shroud being misplaced simplified construction and reduction of variants while dealing with customization.
