接触器通断交流的相位研究

STUDY OF THE PHAsE WHEN THE CONTACTOR SWITCHING THE ALTERNATING

本文研究了接触器通断交流时的相位对接触器工作的影响，提出了在零相位处通断交流电流，可以改进接触器的工作性能，大大延长接触器的使用寿命。以及采用电子控制电路实现零相位通断的具体办法。图４，参２。

The paper has studied the working effect of the phase when the alternating currentof the contactor switching.In this paper,it advances to cut on or cut off the AC whenphase is zero,which may improve the working function of thc contactor and prolong theusing life-span of the contactor.The paper also tells us the wny how to realize zero phasewhen we adopt electron control circuit.4figs. 2refs.
