Switch cabinet

Abstract

The invention provides a switch cabinet comprising a cabinet body, wherein a bus unit, a cable unit and a function unit are arranged in the cabinet body; an insulating function plate is fixedly arranged between the cable unit and the function unit and comprises a front cover plate, a rear cover plate, a bar clamp function piece and a bar clamp fixing piece; the bar clamp function piece comprises a base; a clamping member which can be used for splicing vertical bus bars is transversely arranged on the base; the clamping member comprises a first group of L-shaped grooves and a second group of L-shaped grooves which are respectively and longitudinally corresponding one by one; and copper connecting pieces are respectively and longitudinally arranged between the first group of L-shaped grooves and the second group of L-shaped grooves. When the switch cabinet is used, the vertical bus bars can be respectively arranged in the first group of L-shaped grooves and the second group of L-shaped grooves, the vertical bus bars in the first group of L-shaped grooves and the second group of L-shaped grooves are connected into a whole by the copper connecting piece, and the current carrying capacity of the vertical bus bars reaches 2000A, thereby increasing the safety of the switch cabinet. The invention has simple structure.

Description

Technical field [0001] The invention relates to a switch cabinet and belongs to the technical field of power distribution equipment. Background technique [0002] Switchgear is a device that receives and distributes electrical energy in the power system, and has the functions of controlling, protecting, and detecting circuits. Mainly used in power plants, substations, industrial and mining enterprises and other places. The switchgear includes the main busbar room, the branch busbar room, the functional unit room and the cable room. In order to prevent accidents caused by arcing caused by the failure of the switching elements of the functional unit, a bus insulation function board is usually installed between the functional unit room and the cable room. , Isolate the entry point between the functional unit room and the cable room through the bus insulation function board, thereby improving the safety of the switch cabinet. [0003] At present, the switch cabinet includes a cabinet...

AI Technical Summary

Problems solved by technology

[0004] The busbar insulation function board of the switch cabinet in the prior art includes a front cover plate, a rear cover plate, a clamping function part, and a clamping fixing part, wherein the clamping function part includes a base, and a number of pluggable parts are horizontally arranged on the base. The clamping member connected to the vertical busbar is an L-shaped groove. When in use, the conductor is embedded in the L-shaped groove. The rated current carrying capacity of the bus insulation function board of this structure is only 1000A, and the current switchgear requires vertical busbars. The discharge capacity reaches 2000A. Because the busbar insulation function board cannot meet the design requirements, the vertical busbar is usually disconnected and divided into upper and lower sections to connect with the horizontal busbar. Although this meets the design requirements, there are still potential safety hazards and also unsightly
