摘要
在高新技术支持下,消弧线圈可自动调谐,单相永久接地故障也可自动检出与消除,谐振接地的优点可更好发挥.中国在该领域内发展很快,最近又增添了调容式自动消弧线圈和残流增量法微机接地保护等几种新装置.法国的微机接地保护也有介绍.
Supported by high tech, resonance neutral earthing method is now becoming superior and efficacious than before. New development has been made in China that involves automatic arc suppression coil with adjustable capacitors and microcomputer earthing relay based on increment of residual current etc. While eliminating the conventional inconveniences of traditional equipment, the operation reliability and flexibility of MV compensated network are reaching a higher level. Some new schemes of earthing protection by EDF are also described.
