摘　　要：介绍了TJ40C系列切换电容器交流接触器在无功补偿中的应用。指出了该交流接触器与老产品的工作差异,阐述了接触器工作原理、选型,并通过合闸涌流试验确定控制容量。该交流接触器可作为经济型产品,在某些场合取代成本较高的智能型动态无功补偿装置来投切电容器组。The application of TJ40C series capacitor switching AC contactor in reactive power compensation was introduced. The difference between this series AC contactor and former products was indicated. The working principle and type selection were expounded. The capacity was confirmed via closing current test. This AC contactor is economic and can be replacement of intelligent dynamic reactive power compensation device with high cost to switch capacitors in certain occasion.
