High-voltage bus duct convenient to maintain

Abstract

The invention discloses a high-voltage bus duct convenient to maintain. The bus duct comprises a bus cover plate and a bus bottom plate. The ends, close to each other, of the bus cover plate and the bus bottom plate are fixedly connected with side plates through positioning bolts. The front face and the back face between the two side plates are fixedly connected with homocentric-square-shaped flame-retardant pads, the tops of the homocentric-square-shaped flame-retardant pads located on the side plates are fixedly connected with the bus cover plate, the bottoms of the homocentric-square-shapedflame-retardant pads located below the side plates are fixedly connected with the bus bottom plate, and damping pads are fixedly connected to the inner walls of the homocentric-square-shaped flame-retardant pads. According to the invention, the square through groove is arranged. By means of square through grooves, sliding grooves, partition plates and L-shaped handles, a user can hold the L-shaped handles and push the partition plates, the partition plates can move from the sliding grooves and can be opened, maintenance personnel can maintain internal devices from the square through grooves,dismounting does not need to be completely conducted, a large amount of time is saved, and therefore the maintenance effect is better.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a high-voltage bus duct which is convenient for maintenance. Background technique [0002] Busway is a closed metal device composed of copper and aluminum busbar columns, which is used to distribute large power to various components of the decentralized system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects. Among them, the high-voltage busway is used in large-scale substations, power supply systems and self-provided power plants of large enterprises. It is to replace the traditional bare row wiring method. In addition to being safe, beautiful and reliable, it can also greatly reduce the number of power outage maintenance because the high-voltage busway shell is closed. Faults caused by unbalanced current distribution caused by double-strand and triple-strand high-voltage cables. Ensure the reliability of p...
