Abstract

Electromagnetic component is extremely important for conversion from electrical signal to mechanical signal in spring operating mechanism of a high-voltage circuit breaker. It acts frequently

so its faults occupy a certain proportion of all faults of the circuit breaker. Therefore

it is necessary to assess the state of the electromagnetic component. In this paper

the action process and structural principle of the electromagnetic component in a CT20 spring operating mechanism

as well as the electromagnetic circuit and the resistance in movement

are analyzed. A dynamic model of the electromagnetic component is built from simulation. The current waveforms from simulation coincide with the ones from test

verifying the validity of the model. The movement of the electromagnetic component with abnormal current due to distortion of coils is analyzed via simulation

and a state simulation method based on coil current waveform is proposed for analyzing action process of the electromagnetic component.
