Circuit breaker interlocking component

Abstract

The invention provides a circuit breaker interlocking component which is arranged in the energy storage operating mechanism of a circuit breaker and comprises an interlocking guide rod, a closing guide rod and an energy storage indicating member. The energy storage operating mechanism of the circuit breaker comprises a control component which is connected with the interlocking component in a driving manner and a rotating shaft component which is used for driving closing and separating. The middle part of the interlocking guide rod is rotatably installed on the energy storage operating mechanism. One end of the interlocking guide rod is provided with a limiting part which is arranged to be corresponding to the rotating shaft component and the energy storage indicating member, and the other end of the interlocking guide rod is provided with a driving part which is connected with the closing guide rod in a contact manner. The rotating shaft component and the energy storage indicating member can be cooperated with the limiting part of the interlocking guide rod in the contact manner so that the interlocking guide rod is enabled to act on the closing guide rod. When the energy storage operating mechanism is in the separating energy storage state, the driving part of the interlocking guide rod does not limit the closing interlocking part of the closing guide rod. The circuit breaker interlocking component is accurate in installation, stable in cooperation and compact in structure.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a circuit breaker interlock 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 mech...

AI Technical Summary

Problems solved by technology

The operating mechanism has the same installation method and tripping position as the manual paddle operating mechanism, which realizes interchangeability with the manual paddle operating mechanism, meets the needs of different users, and can overcome the need for the manual paddle operating mechanism to be equipped with external electric accessories The disadvantages of bulky, heavy, high cost and poor reliability of type circuit breakers
