[0002] The traditional frame-type circuit breaker operating mechanism does not have a closing ready indication mechanism, and only provides indications of the stored energy (changed) and non-stored energy (dischanged) of the energy storage spring of the circuit breaker operating mechanism, but cannot correctly indicate the current state of the circuit breaker. Whether it has the only condition and state that can complete the closing operation, because the energy storage (changed) status indication of the energy storage spring of the circuit breaker operating mechanism is only an indication of the necessary conditions for the circuit breaker to complete the closing operation, not Instructions for unique conditions

Embodiment Construction
[0018] The closing ready indicating mechanism of the circuit breaker operating mechanism according to the present invention is composed of a closing ready indicating part extended on the right side plate shaft, the indicating part and a spring on the other shaft. It is characterized in that the closing readiness indicating part is installed on the shaft extended on the side plate and located behind the energy storage indicating part which is also installed on the same shaft extended on the side plate, when the closing ready state indicating part When the indication word "OK" and the indication word "changed" of the energy storage indication part appear in the display window on the operating mechanism panel of the circuit breaker at the same time, the closing ready condition of the operating mechanism of the circuit breaker is met; Other indications in the display window on the operating mechanism panel, such as the indication word "dischanged" of the energy storage indication p...

The invention relates to a switching-on ready indicating mechanism of a circuit breaker operating mechanism, which comprises a ready state indicating part arranged on a shaft extended from a side plate and a spring installed on the ready state indicating part and another shaft. The ready state indicating part is installed on the shaft extended from the side plate and is located behind a stored energy indicating part also installed on the same shaft extended from the side plate. When the indication word 'OK' of the ready state indicating part and the indication word 'changed' of the stored energy indicating part simultaneously appear in a display window on a panel of the circuit breaker operating mechanism, the unique switching-on ready condition of the circuit breaker operating mechanism is satisfied.
Description
technical field [0001] The invention relates to a closing readiness indication mechanism of a circuit breaker operating mechanism, in particular to the improvement of the closing ready indication mechanism of the circuit breaker operating mechanism which cannot uniquely indicate that the circuit breaker can complete the closing ready indication of the existing frame type circuit breaker . Background technique [0002] The traditional frame-type circuit breaker operating mechanism does not have a closing ready indication mechanism, and only provides indications of the stored energy (changed) and non-stored energy (dischanged) of the energy storage spring of the circuit breaker operating mechanism, but cannot correctly indicate the current state of the circuit breaker. Whether it has the only condition and state that can complete the closing operation, because the energy storage (changed) status indication of the energy storage spring of the circuit breaker operating mechanism...
