A circuit breaker energy storage assembly comprises an energy storage lever. One end of the energy storage lever is an energy storage end, and the other end is a drive end. The energy storage end is connected with an energy storage spring installed inside a base support. The middle of the energy storage lever is equipped with an energy storage installation shaft which can be used as a rotation pivot. When the drive end is stressed, the energy storage lever rotates about the energy storage installation shaft, and the energy storage end is driven to act on the energy storage spring to complete storage. The energy storage lever includes at least two energy storage installation pieces arranged side by side. The energy storage installation shaft is arranged through the energy storage lever, and the energy storage installation shaft can be in hole-shaft rotating connection with each energy storage installation piece. The invention provides a circuit breaker energy storage assembly which has the advantages of high assembly efficiency, stable action of the lever, and strong action consistency.
Description
technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to an energy storage component of 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 external op...
