摘　　要：为进一步提升配电网单相接地故障处置能力,变电站内安装主动干预型消弧装置,然而,不同接地方式下主动干预型消弧装置的运行状态及故障处置能力也略有不同。本文对比了不同接地方式下主动干预型消弧装置的防误动性能、非同相接地短路应对性能、接地体周围电位抬升风险、熄弧能力、动作时间及防范铁磁谐振能力,并且从变电站接线方式的改造和主动干预性消弧装置的选择提出了相应的建议。对不同运行场景下主动干预型消弧装置的选择提供了一定的理论依据,具有一定的实际工程价值。The active intervention arc suppression device is installed inside the substation in order to improve the singlephase grounding fault handling capability of distribution network.However,the operation status and fault handling ability of the active intervention arc suppression device under different wiring modes are slightly different.In this paper,the misoperation resistance performance,non inphase grounding short circuit response performance,risk of potential rise around the grounding body,arc extinguishing ability,operation time,and anti ferromagnetic resonance ability of active intervention arc suppression devices under different grounding methods are compared,and the corresponding suggestions in terms of modification of wiring mode of substation and selection of active intervention arc suppression device are proposed.It provides certain theoretical basis for the selection of the intervention arc suppression device and has a certain actual engineering value.
