摘要
分析了中性点经消弧线圈接地电网单相接地故障的特点和保护方法,介绍了KD-XH型消弧系统的原理及其在10 kV电网中的应用状况,应用表明其具有实现对配电网单相接地故障的全过程智能化处理、提供正确补偿及响应速度快的性能。提出了在实际应用中应注意的问题。
The characteristic of single-phase-to-earth fault in neural power grids and protective methods were analyzed. Then grounding via the principle arc suppression coil in of KD-XH type of arc-extinguishing system and its application status in 10 kV power grids were stated. The system can intellectively process the whole procedure of single-phase-to-earth fault; provide correct compensation and response rapidly.
