摘　　要：讨论了切换电容器接触器的若干问题。阐述了其用法、型号、工作原理、预充电触头开距、涌流计算,以及并联使用情况。提出了用晶闸管代替预充电触头的设想。该探讨对提高产品质量有一定的帮助。Some problems of switching capacitor type contactor were discussed. Its usage, type, work principle, opening distance of pre-charge contact, inrush current calculation and parallel use were expounded. The assume that thyristor was applied to replace pre-charge contact was proposed. The discussion is help improvement of product quality.
