Description

Technical Field

[0001] The utility model relates to the technical field of busbar structures, in particular to an AC busbar external protection structure. Background Art

[0002] The busbar refers to the copper or aluminum busbar that connects the main switch in the cabinet and the switches in each branch circuit in the power supply system. The surface is insulated and its main function is to serve as a conductor. It is sometimes also called a busbar. It is the name of the conductive material on the power distribution equipment. It is made of flat copper (equivalent to electric wire) without an insulating layer. It is painted with color paint indicating the phase sequence. It is mainly used to connect indoor transformers to distribution cabinets, then to the main power switch, and then to each branch switch.

[0003] When the existing protective plate is used to protect the busbar, the protective plate is connected to the busbar by tightening bolts. When the distribution cabinet needs to be opened to inspect the busbar or connect the lines, the staff needs to remove the bolts one by one and then remove the protective plate, which makes the disassembly and assembly process of the protective plate very cumbersome, thereby reducing the maintenance efficiency.
