摘要
大容量核电机组用超高压５００ｋＶ送电，为了免受三相重合闸重合到线路多相永久性故障的再一次严重冲击，宜用单相重合闸，又为了单相重合闸动作的可靠性，宜用简单可靠的重合闸。本文介绍的是大亚湾核电站用的５００ｋＶ线路重合闸———英国Ｒｅｙｒｏｌｅ公司的ＭＧＡＡ线路重合闸。
Nuclear power generating set of large capacity adopts UHV 500kV power transmission.To avoid the severe rush of the three-phase recloser which switches on multi-phase permanent fault,it is suitable to use single-phase recloser.In order to improve the operational reliability of the single-phase recloser,it is appropriate to use the simple and reliable recloser.This paper introduces the 500kV line recloser used for the Dayawan nuclear power station——MGAA line recloser from British Reyrolle Company.
