10千伏高压开关柜在城市配网中被广泛使用.随着廊坊电网的不断发展,负荷不断增大,电力用户对供电可靠性的要求也越来越高.用户端10千伏设备来自不同的生产厂家,由于在设计、制造、安装和运行维护等方面存在着不同程度的问题,因而事故率比较高.有的甚至影响电网安全运行.这类事故应该引起运行维护人员的重视和反思.本文结合实践经验,介绍10千伏高压开关柜的分类和基本特性,总结一些常见的开关柜故障,分析原因并提出预防措施.%The 10KV high voltage switch cabinet is widely used in city distribution network. With the continuous development of Langfang power grid, the load is increasing, and the power user has higher requirements for the reliability of power supply. The 10KV devices in user terminal come from different production manufacturers. It has problems in design, manufacture, installation and operation and maintenance in different level, so the accident rate is higher, and some accidents even influence the safe operation of power grid. So workers should give attention and reflection to these accidents. Based on practical experience, this paper gives a introduction about the classification and essential characteristics of 10KV high voltage switch cabinet, summarizes some common faults, analyses the reasons and puts forward the preventive measures.
