摘　　要：介绍一种用于低压无功补偿装置中的智能复合开关(共补)。采用晶闸管和磁保持继电器并联,晶闸管和继电器分时导通,充分利用了继电器功耗小,晶闸管响应快、动作可靠的特点,解决了无功补偿中电容投切产生的涌流大、功耗大等问题。An intelligent complex switch used on low-voltage and no-power compensatory device was indtroduced. It adopts a parallel structure of thyristor and magnetic latching relay. The thyristor and the relay will be on at different time, so the complex switch has the strong point of silicon-controlled rectifier which has the quickly response and high dependability and the magnetic latching relay which has low power, and the switch solve the problems when the capacitor plunge into or remove from the three-phrase power.
