Cabinet body of high-voltage switch cabinet

Abstract

The invention relates to a cabinet body of a high-voltage switch cabinet, which is characterized in comprising a sectional material framework, a cabinet body top plate, a busbar chamber side plate, a cable chamber side plate, an instrument box side plate, an instrument box relay board, a breaker side plate, a cabinet body base plate, a left framework, a beam and a right framework. The cabinet body provided by the invention has the advantages that a sectional material is adopted as the framework of the cabinet body, and the cross section of the sectional material is in a thin-wall shape as a whole, so that the material waste cause by that a circular or rectangular cavity of the existing sectional material adopts a same all thickness is avoided; the design of a T-shaped groove is convenient for realizing convenient and fast assembly, and the T-shaped groove has the characteristics of clear edges, smooth lines and the like; the sectional material with specially-designed cross section has the characteristics of saving raw materials and having high bending strength; lap joint between the sectional materials and between the sectional material and other parts is simple, so that the productive efficiency is improved and the productive period is reduced; and other metal plate parts play the role of partition, have low requirements in strength and are only required to be bent simply, so that the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to a high-voltage switch cabinet body. It belongs to the field of high-voltage electrical appliances. Background technique [0002] The structure of the existing high-voltage switchgear is generally in two forms: profile welding cabinets represented by products such as JYN1, KYN1, and XGN2, and bent plate assembly cabinets not represented by products such as KYN18 and KYN28. The welding cabinet mainly uses welding technology as a means of overlapping parts, and the cabinet body is welded by steel plate materials such as angle steel, channel steel and other parts. The welding cabinet structure is simple, the contact strength of the overlapping parts is high, and the rigidity of the cabinet body is good. But at the same time, it has defects such as rough processing methods, low precision, large welding deformation and long production cycle; the assembly cabinet mainly uses the assembly of parts as a means of overlapping parts, and ...

AI Technical Summary

Problems solved by technology

But at the same time, it has defects such as rough processing methods, low precision, large welding deformation and long production cycle; the assembly cabinet mainly uses the assembly of parts as a means of overlapping parts, and uses threaded fasteners to support sheet metal parts supported by steel plates or aluminum-zinc plates. connection composition

The assembly cabinet has advanced processing methods and high assembly precision, but at the same time, the cabinet structure is relatively complicated. In order to improve the strength of parts and parts, most parts are manufactured using multiple bending processes, which leads to high manufacturing costs.

Due to the multi-bending processing technology, the utilization rate of raw materials is not high, the weight of parts is large, and the assembly strength is high, which virtually prolongs the manufacturing cycle
