| 摘 要： | 不少变电站进行10kV线路控制回路综合自动化改造成微机保护后，经常出现跳／合闸线圈烧毁情况，针对烧毁原因进行分析发现，通过是由于开关机构故障造成跳／合闸困难、保险容量选择不当、电压过高、控制回路一些接点不能延时返回致使长时间通电等造成烧毁线圈。对此，提出了解决的的办法和措施。

| Abstract: | Coil burnout often happened after microcomputer protection implemented in 10 kV control circuit.Reasons of burnout were analyzed such as trip or closing difficulty caused by switch mechanism fault,improper insurance capacity and voltage overtension.Solutions were proposed:use high quality circuit breaker,maintenance,suitable insurance capacity and reform on loop voltage. |
