Abstract

Provided is a spring operating mechanism. The problem that an existing brake opening pawl is not reliable in actions is solved. The spring operating mechanism comprises a front plate, a middle plate and a base plate, wherein an output spindle is arranged between the front plate and the base plate, a brake opening half shaft and a mounting shaft are arranged between the middle plate and the front plate, a press crank arm is arranged on the output spindle, a brake opening pawl is arranged on the mounting shaft and comprises a pressing block and a limiting block, and the first state that the pressing block is pressed by the press crank arm, the second state that the limiting block is pressed to enable the limiting block and the brake opening half shaft to be clamped mutually, the third state that the pressing block rotates to enable the press crank arm to be limited in rotation and the fourth state that the brake opening pawl resets to enable the pressing block and the press crank arm to be unlocked after brake opening are set for the pressing block. The spring operating mechanism is provided with the pressing block and the limiting block, so that the press crank arm of the output spindle can reliably press the pressing block, the pressing block reliably drives the limiting block to move and enables the limiting block to be reliably clamped with the brake opening half shaft.

Description

technical field [0001] The invention relates to a circuit breaker operating mechanism, in particular to a spring operating mechanism. Background technique [0002] In order to meet the needs of sustainable development and environmental protection, my country's power transmission and transformation has developed rapidly, especially the ultra-high voltage power transmission ranks at the leading level in the world, and UHV power equipment such as circuit breakers and fully enclosed combined electrical appliances have been domestically produced. The operating mechanism used for circuit breakers is usually a spring operating mechanism. The spring operating mechanism is a mechanical operating mechanism that uses an energy storage spring as an energy storage element. It is kept in the energy storage state through the locking system. When breaking, the lock releases, the energy storage spring releases energy, and the crank arm drives the switch to move through the mechanical transm...
