Abstract

The invention discloses a spring operating mechanism transmission energy storage device. The device comprises an energy storage shaft and a shell frame, wherein two ends of the energy storage shaft are rotatably connected in the shell frame, a prime mover is further connected in the shell frame, the energy storage shaft is movably connected with a large gear, the side surface of the large gear isconnected with a pawl, the energy storage shaft is connected with a round wheel and a hanging spring crank arm, the pawl is connected with the round wheel, and the output end of the hanging spring crank arm is connected with a closing spring. An output gear on the prime mover rotates to drive a large gear to rotate, a pawl on the large gear drives an energy storage shaft to rotate through a roundwheel, and the energy storage shaft drives a hanging spring crank arm to rotate to compress a closing spring to achieve energy storage. According to the device, through optimized layout and gear transmission optimization design, two-stage gear transmission is adopted, the structure is compact, the layout is reasonable, and the number of parts is reduced. Compared with a traditional spring operating mechanism energy storage device, the number of the parts is reduced by 20%, fault points are reduced, and the reliability of the mechanism is improved.

Description

technical field [0001] The invention relates to the technical field of switchgear control, in particular to a transmission energy storage device for a spring operating mechanism. Background technique [0002] As an important switching element in the power system, the circuit breaker plays a role in control and protection. The reliability and intelligence level of its action directly determine the reliability and automation level of power supply and distribution in the power system. The circuit breaker is mainly composed of the circuit breaker body and the operating mechanism. The function of the circuit breaker body is to cut off the load or short-circuit current; the function of the operating mechanism is to realize the opening and closing of the circuit breaker contacts and satisfy the contact Various requirements for opening and closing characteristics. [0003] At present, the integrated spring operating mechanism and single-module spring operating mechanism widely used...
