  • To solve problems of low compensation precision of pre-adjusted type arc suppression coil and bigger residual current and slow compensation speed of grounding point of post-set arc suppression coil, the paper gave structure of a new type of arc suppression coil with full compensation combining with advantages of pre-adjusted and post-set arc suppression coil. It established a simulation model of characteristics of controlled reactor and 10 kV power network to ground with the new type of arc suppression coil. The simulation results showed that when 10 kV power network happened single-phase ground fault, the main arc suppression coil can quickly operate, and compensate most of capacitive current; subordinate arc suppression coil can compensate accurately with fine turning after response time. The new type of arc suppression coil can improve both speed and accuracy of compensation.
