Circuit breaker energy storage operating mechanism

Abstract

The invention provides a circuit breaker energy storage operating mechanism comprising a side plate component, a connecting rod component, a cam component, an energy storage component, a rotating shaft component, a control component and an interlocking component. The side plate component is internally provided with a driving shaft capable of rotating. The connecting rod component and the cam component are installed on the driving shaft. The connecting rod component is connected with the rotating shaft component. The cam component can be connected with the energy storage module in a contact manner to push the energy storage module to store energy. The rotating shaft component can be driven to realize closing through the connecting rod component when the energy storage module releases energy. The control component can be connected with the connecting rod component and the cam component in a locking manner. The control component is connected with the interlocking component in a driving manner and enables the energy storage module to release energy to complete closing through the cam component. The control component and the connecting rod component are separated so that the rotating shaft component is enabled to return to complete separating action. The circuit breaker energy storage operating mechanism is simple in structure, stable in action and easy and convenient to assemble.

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 ...

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
