摘要
KYN28A-12铠装型移开式交流金属封闭开关设备（以下简称开关柜）系三相交流50 Hz的户内成套配电装置,用于接受和分配3.6~12 k V的网络电能并对电路实行控制保护及监测。某电厂运行的开关柜故障率很低,维护工作量也很少,基本免维护。在分析处理一起电源开关柜故障时,发现很多问题,探讨了该问题发生的原因及改进办法。
Metalclad removable AC metal- enclosed switchgear is indoor power distribution device, which acts on receiving and distributing 3.6-12 k V network power quality, and realizing control protection and monitoring. In the past, the fault rates of switchgear operated in Gujiao power plant was very low and less maintenance is needed, while recently, a switchgear fault occurred. In view of the fault, analysis was done and problems were identified. Finally, measures for improvement were put forward correspondingly.
