| 摘 要： | 针对电磁开关和电力电子开关投切电容器在无功补偿装置应用中存在的问题,研制了一种基于单片机(AT89C52)并应用于低压无功补偿装置的复合开关。该复合开关与接触器、晶闸管投切电容器(TSC)相比,其主要优点在于它既有晶闸管过零投切电容器时电网浪涌电流小的优点,又有接触器闭合时晶闸管无功耗节能的优点。

| Abstract: | A kind of composite switch was developed to be applied for low voltage reactive power compensation equipment based on single-chip AT89C52 against problems of switching with electromagnetic and electric power electronic circuit breakers on capacitors in reactive power compensation equipment.Using this composite switch,compared with switching on capacitors by contactor or thyristor,will show both advantages of small surging current at operating capacitor by thyristor passing zero and energy conservation on the thyristor at the closing of contactor. |

| Keywords: | composite switch reactive power compensation operating passing zero |
