| 摘 要： | 选用四星型MOA作为限制真空断路器操作过电压的主保护器，效果十分明显，但选用何种型式的四星型MOA则取决于真空断路器所开断的负荷种类。R-C阻容吸收器作为四星型接法MOA的后备保护器，解决了四星型接法MOA实际存在的放电分散性使保护灵敏度下降问题，改善了过电压波形，降低了避雷器的残压。

| Abstract: | The effect was obvious to select four-star connection MOA was a main protector to limit overvoltage in operation of a vacuum disconnector. But, selection of type of the four-star connection MOA depended on kind of load switched off and on by the vacuum disconnector. In actual operation, discharge dispersivity of the four-star connection MOA would reduce sensitivity of protection. R-C absorption device as a spare protector of the four-star connection MOA solved the above problem, improved waveform of the overvoltage and reduced residual voltage of a lightning rod. |
