High-voltage vacuum circuit breaker contact and wafer forming processing technology

Abstract

The invention relates to a high-voltage vacuum circuit breaker contact and wafer forming processing technology which comprises a bottom plate, an adjusting device, a polishing device and a driving device, the adjusting device and the polishing device are sequentially installed at the upper end of the bottom plate from inside to outside, the driving device is arranged on the outer side of the adjusting device, and the driving device is rotationally connected with the bottom plate. The technology can solve the problems that when existing equipment grinds an annular sheet opening of a high-voltage vacuum circuit breaker contact, corresponding adjustment cannot be conducted according to the size and the opening number of the annular sheet, the equipment cannot be matched with the annular sheet, the applicability of the equipment is reduced, meanwhile, the grinding distance cannot be adjusted, and the equipment cannot enter the opening of the annular sheet due to the fact that the distance is too large in the initial state of the equipment, the grinding success rate is reduced, the equipment cannot be attached to the opening of the annular sheet during grinding, and the grinding effect is reduced are solved.

Description

technical field [0001] The invention relates to the technical field of circuit breaker production, in particular to a forming process for contacts of high-voltage vacuum circuit breakers. Background technique [0002] Vacuum circuit breaker is named for its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are high vacuum; vacuum circuit breaker has the advantages of small size, light weight, suitable for frequent operation, and no maintenance for arc extinguishing. It is widely used in power grids; vacuum circuit breakers are divided into low-voltage and high-voltage according to voltage, and high-voltage vacuum circuit breakers are connected to other equipment through contact pieces, which need to be polished during production and processing. [0003] At present, the existing equipment usually has the following deficiencies when grinding the ring piece opening of the contact of the high-voltage vacuum circuit breaker: 1. The exis...

AI Technical Summary

Problems solved by technology

[0005] The invention can solve the problem that the existing equipment cannot be adjusted according to the size and number of openings of the ring piece when grinding the ring piece opening of the contact of the high-voltage vacuum circuit breaker. In the application occasion, the applicability of the equipment is reduced. At the same time, the grinding distance cannot be adjusted. The initial state of the equipment is prone to the phenomenon that the distance is too large and cannot enter the opening of the ring piece, thereby reducing the success rate of grinding. Moreover, when the equipment is grinding It cannot be fitted with the opening of the ring sheet, which reduces the effect of grinding and other problems
