Abstract

A handle assembly of a circuit breaker, including a handle mounted on a drive shaft, a ratchet and a cam assembly are fixedly installed on the drive shaft, the cam assembly is in contact with the energy storage assembly of the circuit breaker, and the handle can pass through the ratchet The drive shaft is rotated to drive the cam assembly to drive the energy storage assembly for energy storage, and the handle is provided with a first pawl that engages with the sawtooth on the edge of the ratchet. The invention provides a circuit breaker handle assembly with flexible use, stable structure and reliable action.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a circuit breaker handle assembly. 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 external operating mechani...
