Details智能接地故障发展控制系统适用于中性点不接地或经消弧线圈接地的6kV、10kV、35kV和66kV配电网。系统中的智能消弧和选线装置部署在变电站的6kV、10kV、35kV和66kV的母线上，当配网系统发生单相接地短路时，主动在变电站故障相母线制造短时间的稳定的金属性接地短路，使得流过远方故障点的接地电流转移至母线处接地点，可有效熄灭故障点电流拉弧、抑制弧光暂态过电压，防止电弧引起失火和设备绝缘击穿等大事故，同时保证瞬时性单相接地故障点的绝缘自恢复。装置在实行故障发展控制的同时，内带的就地选线装置可快速准确地指示出故障线路，为永久性接地短路情况下的后续故障隔离和清除处理创造条件，提高配网运行安全性及供电可靠性。
The Smart Distribution Grid Monitoring System consists of SGS and SFPlatform. SGSs can be easily installed on overhead lines, underground cables and underground-to-overhead transit points. They are used to measure the line current, …
