The invention relates to a breaker energy storage operating mechanism. The breaker energy storage operating mechanism comprises an energy storage assembly and a rotation shaft assembly, wherein the energy storage assembly comprises a fixedly-arranged energy storage mounting shaft, the energy storage mounting shaft is equipped with an energy storage lever capable of rotating around the energy storage mounting shaft, the rotation shaft assembly is provided with a first cantilever which can be in coupling connection with a contact system of a breaker, the first cantilever can be connected with an end portion of a connection rod assembly of the energy storage operating mechanism, the connection rod assembly can be driven during energy release of the energy storage assembly to drive the rotation shaft assembly to rotate to drive the contact system to realize closing, and a main pull spring used for driving the rotation shaft assembly to reset is arranged between the first cantilever and the energy storage mounting shaft. The breaker energy storage operating mechanism has advantages of compact structure, reliable cooperation and accurate motion.
Description
technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to an energy storage operating mechanism for a circuit breaker. Background technique [0002] At present, the operating mechanism of the molded case circuit breaker is usually a manual paddle type. If the user needs electric operation, an external electric operation accessory is often provided to install outside the circuit breaker to realize the function of electric and remote control of the circuit breaker. However, for large-capacity molded case circuit breakers, the accessories of the external operating mechanism often have a large volume and weight, and thus have high requirements for installation quality, especially when the operating mechanism is matched with the circuit breaker body. Shock vibration is likely to cause failure of key parts such as the circuit breaker housing and locking device, resulting in failure. Therefore, the existing accessories of the ...
