STRUCTURE FOR MAINTAINING CONTACT FORCE WITH THE WIPE SPRING ON THE VACUUM CIRCUIT BREAKER

摘要

The present invention relates to a contact pressurizing structure of a vacuum circuit breaker, wherein a pressure spring (41) for elastically pressurizing the contacts (25) and (25 ') is provided on the side of the mechanism, and the rear end of the conversion lever (28) is pressed in the form of a lever. Since it is possible to use a pressure spring 41 having a relatively smaller spring force than in the related art, even if the pressure spring 41 is damaged due to fatigue caused by repeated use for a long time, only the case of the mechanism part is dismantled and then easily repaired. It is possible.
