Opposing Force

The presence of an arc in a circuit breaker interrupter creates an opposing force to the driving mechanism by changing of the pressure field. This opposing force alters the dynamics of the driving mechanism, the travel characteristics of the moving contact and therefore the switching process. The severity of the influence depends on the structure of the interrupter, the travel profile and also the current waveform, especially the magnitude of the fault current. A 252 kV puffer circuit breaker was used in the present work to study the key factors that contribute to the uncertainty of the predicted contact travel based on coupled simulation.

This article develops the automatic test system of voltage and current dynamic waveform for circuit breaker. The system has the automatic monitoring, the storage and the display function of contact voltage and current waveform of circuit breaker in switching process. And then, it also designs the hardware and software of voltage and current dynamic monitoring system for miniature circuit breaker: the hardware circuit of this test system mainly consists of the detection circuit and the data acquisition circuit of current and voltage. And the software system, which mainly consists of control program, data acquisition program and data processing program, is programmed under the condition of LabVIEW. At last, it carries on the real-time monitor to the voltage and current waveform at the both ends of the circuit breaker, especially for the waveform during the switching process, which contributes to study the arc energy and contact wear of circuit breaker.
