Problems solved by technology

However, as the distance between the moving contact and the static contact becomes longer, the magnetic field will be greatly weakened with the increase of the opening distance, and the arc at a large opening distance cannot be controlled, and the arc groove is weakened for such a magnetic field powerless

Abstract

The invention provides a vacuum arc extinguish chamber (100 and 100 '). The vacuum arc extinguish chamber comprises a housing (1), a fixed contact (4) accommodated in the housing (1), a moving contact (5) which is accommodated in the housing (1) and is configured to move so as to be connected with or separated from the fixed contact (4). a conducting seat (12) which is fixedly mounted in the housing (1) and is configured to keep electrical connection with the moving contact (5), and a flexible electric connection structure which is accommodated in the housing (1) and is used for connecting the moving contact (5) with the conducting seat (12); and the moving contact (5) is operated such that the moving contact (5) can be made to move an operation mechanism. The invention also provides a vacuum circuit breaker comprising the above vacuum arc extinguish chamber.

Description

technical field [0001] The invention relates to a vacuum interrupter, especially a vacuum interrupter for a vacuum circuit breaker. Furthermore, the present invention also relates to a vacuum circuit breaker. Background technique [0002] Vacuum interrupter is the key component of vacuum switch or vacuum circuit breaker. It is responsible for controlling the arc. The breaking and closing of current and arc are all completed by the contact movement in the vacuum interrupter. The basic components of the existing vacuum interrupter include the moving contact, the static contact, the conductive rod of the moving and static contact, the insulating shell, the shielding cover and the bellows, etc. For example, the Chinese utility model patent ZL 200520034035.3 discloses a typical vacuum interrupter interrupter. The conductive rod of the moving contact in the prior art is used on the one hand to guide the current of the moving contact, and on the other hand serves as an actuating ...
