Description

Technical Field

[0001] The utility model relates to the technical field of electrical accessories, in particular to a copper plate assembly for electric power equipment. Background Art

[0002] Copper plate is a metal material with high electrical conductivity, high thermal conductivity and corrosion resistance. In the power system, copper plate plays a vital role due to its excellent electrical conductivity and stability. Copper plate is often used to make busbars and conductive bars in the power system. Busbars are conductors that collect and distribute electrical energy in the power system, while conductive bars are used to connect various electrical equipment.

[0003] Copper busbars are used to connect primary components with larger currents in electrical cabinets. For example, a row of electrical cabinets has a main busbar connecting the cabinets. Branch busbars connect the main busbar to the switchgear (disconnectors, circuit breakers, etc.) on each cabinet. In existing distribution cabinets, the connections between busbars are mainly fixed with bolts and nuts. This connection method is prone to loosening, but the busbar connections in existing distribution cabinets are not fixed. Utility Model Content
