Bus supporting construction

Abstract

The invention discloses a bus supporting construction. The construction comprises a bus cylinder, a bus conductor, an insulator and a fastening bolt, wherein the insulator is used for supporting the bus conductor and the fastening bolt is used for fixing the insulator. The bottom of the insulator is provided with at least an adjusting stud; the top of the adjusting stud supports the insulator; the bus cylinder is inserted through the bottom of the adjusting stud and the bottom of the adjusting stud is cooperated with screw threads of the bus cylinder; and an inserted outboard position at the bus cylinder is sealed by an outer cover. According to the bus supporting construction provided in the invention, a technical scheme of adjustment on a stud is employed; a height of an insulator can be adjusted outside a bus cylinder; therefore, supporting forces provided by the insulator can be maintained to be consistent and uniform support is obtained by a bus conductor; moreover, a local stress that is caused by nonuniform support is reduced and thus service life of a bus is improved; and the bus supporting construction is suitable for application to a high voltage class bus.

Description

technical field [0001] The invention relates to a bus support structure, in particular to a support structure whose height can be finely adjusted. Background technique [0002] The bus bar and the common box bus bar are one of the basic components of the closed electrical appliance. They are connected with other components of the closed combined electrical appliance through the diversion connector to meet different wiring methods of the main line to collect, distribute and transmit electric energy. CN201616630U discloses a common box busbar, comprising a busbar barrel and a busbar conductor arranged in the busbar barrel, the busbar cutter body is supported by an insulator, and a supporting bent plate is provided on the inner wall of the busbar barrel at the bottom of the insulator, and the insulator and the supporting bent plate pass through Tighten the bolts to secure the connection. The busbar support structure with the above structure has the following problems: as the v...

AI Technical Summary

Problems solved by technology

The busbar support structure with the above structure has the following problems: as the voltage level increases, the length of the busbar barrel will also increase, and the processing difficulty of welding the support bent plate and the inner wall of the busbar will also increase, especially in the middle part of the busbar barrel In addition, the length and weight of the busbar conductors will increase with the increase of the voltage level. Correspondingly, more insulators and supporting bent plates are required to support the heavier busbar conductors, which is even heavier. The processing of the support bending plate is difficult, and the processing accuracy will also be affected, which often causes the support height of each insulator to be inconsistent, resulting in the inability of the busbar conductor to be uniformly supported by each insulator, which is prone to local stress and reduces the service life of the busbar
