Abstract
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.
