Abstract

The invention discloses an adjustable circuit breaker opening mechanism, which comprises a fixed seat, a top head, a mounting bottom block, a sliding block and a driving unit. The driving unit can drive the top head to move so as to push a circuit breaker emergency opening tripping button; the mounting bottom block is connected with the fixed seat in a sliding mode in a first direction, the sliding block is connected with the mounting bottom block in a sliding mode in a second direction, the second direction, the first direction and the driving direction of the driving unit are all perpendicular to one another, and the driving unit is mounted on the sliding block. In the adjustable circuit breaker opening mechanism, the position between the fixed seat and the driving unit can be adjusted in a sliding manner along the first direction and the second direction; according to different circuit breaker structures, the mounting bottom block and the sliding block are driven to slide, and the problem of inapplicability of the adjustable circuit breaker opening mechanism caused by different types of circuit breakers can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, and more specifically relates to an adjustable opening mechanism of a circuit breaker. Background technique [0002] In the 10kV power distribution room, the most commonly used switchgear is: KYN28 armored removable switchgear. The vacuum circuit breaker of this equipment has the function of remote control opening and closing, which can realize remote automatic opening and closing. However, with the increase in the number of openings and the interference of some external environmental factors, the opening motor coil of the vacuum circuit breaker will often fail, resulting in failure to automatically open and close. After this kind of situation occurs, the circuit breaker is often still in a charged state. At this time, the circuit breaker can only be repaired or replaced after the charged state is released by manually pressing the "emergency opening and tripping button". But there will ...
