A spring operating mechanism

Abstract

The invention discloses a spring operating mechanism. In the spring operating mechanism, there are more than two output shafts, and the anti-rotation corresponding to each output shaft is equipped with an output toggle arm, and the free ends of each output toggle arm are respectively connected to corresponding On the chute opened on the output cam (E), each output crank arm forms a swing guide mechanism through the corresponding chute and the output cam (E). Therefore, more than two output shafts are driven by one output cam, and each output shaft will drive the corresponding isolating switch or circuit breaker to open and close. At the same time, the chute on the output cam makes the eccentrically anti-rotating output crank arm and the output cam on the output shaft form a swing rod guide mechanism, and each swing rod guide mechanism will ensure the reliable transmission of torque from the output cam to the output crank arm to pass The ingenious connecting rod transmission mechanism realizes reliable transmission effect and improves the performance stability and service life of the spring operating mechanism.

Description

Technical field [0001] The invention relates to a spring operating mechanism. Background technique [0002] At present, electromagnetic mechanisms are often used in the linkage control of the opening and closing actions of vacuum circuit breakers and isolating switches, but the closing voltage of the electromagnetic structure is AC220V, the closing power is too large, and the power quality requirements are very high. The power supply system is coordinated, and the accumulated tolerances of the coils and iron cores of the electromagnetic mechanism will cause the magnetic field to be unstable, which will seriously affect the reliability of the opening and closing actions of the vacuum circuit breaker and the isolating switch. [0003] A Chinese patent specification with application number 201210141851.9 discloses a circuit breaker spring operating mechanism, which includes a frame and a closing unit, an opening unit, and an output assembly assembled in the frame. Among them, the clo...

Problems solved by technology

[0004] In the above-mentioned spring operating structure, the closing unit and the opening unit drive the output shaft in the same output assembly to rotate, so as to realize the opening and closing actions, that is, the above-mentioned spring operating mechanism can only output one torque, so that the spring operating mechanism It can only be used to control the opening and closing action of the circuit breaker, but cannot transmit the opening and closing action to the isolating switch linked with the circuit breaker, so that the linkage effect of the opening and closing action of the isolating switch and the circuit breaker is affected, and there is still low reliability in use The problem
