Abstract

The invention discloses a fully-integrated spring operating mechanism for a high-voltage alternating-current circuit breaker. An auxiliary switch is fixed on a left side plate of the mechanism; an energy storage motor is fixed on a right side plate of the mechanism; a gear pair, an energy storage shaft and an output large shaft are supported fixedly by the left side plate and the right side plate of the mechanism; the upper end of an energy storage spring is connected with the energy storage shaft; a switching-in maintenance module is positioned between the left side plate and the right side plate of the mechanism; a buffer is fixed on the right side plate of the mechanism by using bolts; a tripping maintenance module is fixed on the left side plate of the mechanism by using screws; a tripping spring which is in controlled connection with a tripping electromagnet is fixed outside the right side plate of the mechanism; and a mechanical interlock, a manual tripping button, a microswitch, a manual switching-in button and a switching-in electromagnet are assembled on the right side plate of the mechanism by using the bolts. The mechanism has a simple and compact structure and complete functions, can be assembled independently, and is convenient for batch production.

Description

technical field [0001] The invention belongs to a high-voltage AC circuit breaker, in particular to a fully integrated spring operating mechanism of a high-voltage AC circuit breaker. Background technique [0002] The structure of the existing spring operating mechanism for vacuum circuit breakers is basically divided into three types: an integrated structure with the circuit breaker frame, a modular structure assembled in the mechanism box, and a semi-integrated integral mechanism. Some structural units in these structures are separated from the mechanism. , Assembled in other parts of the circuit breaker not only has a large number of parts, but also is not easy to realize the adaptation with different types of circuit breakers. Contents of the invention [0003] The purpose of the present invention and the present invention integrates all the structural elements in the mechanism box into the mechanism, leaving interfaces with other functional components of the vacuum ci...
