摘要
某变电所是某220 kV电网中的一个重要枢纽变电站之一,为保证其安全运行,从线路在设计的结构以及实际运行情况出发,对连续半年内的五次保护动作跳闸情况进行了分析,找到了该线路出现故障的原因,并对110kV线路在电网中的运行维护进行了详细阐述。对同类变电站运行有借鉴意义。
The below mentioned transformer substation is a key one in the 220 kV power grid. The paper, based on the site design structure and its practical operation,analyses the five tripping during the half year of its operation, finds out to causes and elaborates the maintaining methods of 110 kV line during operation,which has some reference to other similar transformer substations.
