Embodiment

[0015] The invention provides the functions of making the vacuum circuit breaker close, keep in the closed state, open, close and open state indication, energy storage indication, manual operation, mechanical counting and the like.

[0016] The present invention includes a frame, an energy storage motor 2, an energy storage transmission system, a closing mechanism, and an opening mechanism. The energy storage transmission system includes a gear pair 16 and a sprocket pair 17. 2. The gear pair 16 and the chain wheel pair 17 are connected to the energy storage shaft 12, and the gear pair 16 and the chain wheel pair 17 are respectively a pair. The energy storage shaft 12 links to each other with the energy storage spring 15, so that the energy storage spring 15 stores energy, and the sprocket pair 17 is sleeved on the outer surface of the steel sleeve 18 through a key connection, and the steel sleeve 18 is connected with the roller 19; the energy storage shaft 12 is connected with...

Abstract

The invention discloses a spring operating mechanism for a breaker to solve the current problem. The mechanism comprises a frame, an energy-storing electric engine, an energy-storing transmission system, a switching-in mechanism, a switching-out mechanism; the energy-storing transmission system comprises a gear pair and a chain wheel pair; the switching-in mechanism comprises a switching-in electromagnet and a switching-in quantum; the switching-in electromagnet is provided at side end of the switching-in quantum; the switching-in quantum is rotatably installed on a support shaft; the switching-in quantum is connected with a cam; the switching-out mechanism comprises a switching-out electromagnet, a tripping board and a switching-in holding quantum; the switching-out electromagnet is provided at the side end of the tripping board, the tripping board is connected with a half shaft, the switching-in holding quantum is rotatably installed on the support shaft; the switching-in holding quantum is connected with the half shaft; the half shaft, the support shaft and the energy-storing transmission system are supported by a left side board and a right side plate which are connected to a frame through the shaft. The invention has simple and compact structure, less components, perfect functions, high reliability, small volume, light weight, convenient maintenance and integrated operation buttons and state indicating distribution.

Description

technical field [0001] The invention relates to a spring operating mechanism for a circuit breaker. Background technique [0002] Since the 1980s, the design and manufacturing level of vacuum circuit breakers in my country have made considerable progress, and all major performance indicators have been significantly improved. At present, there are ZN12, ZN28, ZN63, ZN65 and VEP types The indoor high-voltage AC vacuum circuit breaker is the product with the largest coverage and relatively advanced technology among many domestic vacuum circuit breakers. As far as the operating mechanism of the circuit breaker is concerned, there are early independent mechanisms based on ZN28. This mechanism is convenient for organizing production , but its relative position positioning with the circuit breaker main circuit pole transmission system is not very accurate, and the volume is large and the structure is complex. Later, foreign vacuum circuit breakers gradually entered the Chinese marke...
