Problems solved by technology

[0004] The above-mentioned patent has the following disadvantages: although it can prevent bouncing to a certain extent, its stroke to the closing direction is still open when the switch is off, and its anti-bounce device cannot lock it. In practical applications, it will There are situations such as accidental touch and accidental touch that cause the moving contact to move, and there are certain potential safety hazards

Abstract

The invention discloses an anti-bounce assembly of an automatic change-over switch and processing equipment of the assembly, relates to the technical field of change-over switches, and aims to solve the safety problem. The anti-bounce assembly of the automatic change-over switch specifically comprises a shell cover, an anti-bounce closing piece and an opening and closing piece are arranged on theouter wall of the shell cover, the opening and closing piece comprises a static contact and a moving contact, a torsion shaft is rotatably connected to the inner wall of the shell cover, a cam sleevesthe outer wall of the torsion shaft, and a matching block is used in cooperation with the outer wall of the top of the cam. Through the arrangement of the clamping block and the groove, the pawl canslightly rebound in actual use, the groove formed in the pawl can be clamped into the clamping block on the matching cylinder when the pawl rebounds, at the moment, the torsion shaft cannot rotate inthe closing direction even if mistaken touch occurs, and when closing is needed, the groove can extend out of the clamping block and then the torsion shaft is rotated along the closing direction by only rotating thethe torsion shaft in the opening direction, so that the safety is improved while the basic functions are ensured.

Description

technical field [0001] The invention relates to the technical field of transfer switches, in particular to an anti-bounce component of an automatic transfer switch and its processing equipment. Background technique [0002] Contact bouncing is a serious hazard to electrical appliances with contacts, that is, after the moving and static contacts of the circuit breaker reach the maximum opening distance, there will be a large rebound, and the rebound range can reach half of the opening distance, and even the moving and static contacts will appear. In the case of contact again, this bouncing will cause the arc not to be extinguished in time or even the arc to reignite, which seriously affects the breaking ability of the circuit breaker. [0003] After retrieval, the Chinese patent publication number is the patent of CN105719857A, discloses a kind of anti-bounce device of automatic transfer switch, comprises the anti-bounce mechanism of mechanism frame, two mirror images, and th...
