LW14—145型高压SF_6断路器在西宁供电局的应用

Application of LW14—145 High—voltage SF_6 Circuit Breakers in Xining Electricity Supply Bureau

随着电力企业的不断发展 ,无油化、免维护、可靠性高的设备将逐步取代油开关。西宁供电局近年来逐步开展了对 1 0kV、1 1 0kV油开关的更换工作 ,不仅积累了许多宝贵的经验 ,培养了一批有较高素质的检修人员 ,更主要的是在很大程度上提高了设备的可靠性 ,保证了电网的安全运行。文章对目前红湾变电所1 1 0kV开关改造工程中采用的LW 1 4— 1 45型SF6断路器做了详细的介绍 ,并结合以往的检修经验做了总结、分析 ,提出了对此类型开关在今后检修工作中应注意的事项。

With developing of electric power enterprise,the devices for oil less,maintenance—free and high—reliability step by step replace oil switch.For several years Xining Electricity Supply Bureau have developed replacing work for 10kV and 110kV oil switch.In the process they not only accumulate a lot of valuable experiences and develop High—diathesis examine and repair personnel,but also advance reliability of device and assure electrical network safely running.The paper detailed introduces LW14—145 SF 6 circuit breakers in HongWan transformer substation,provides attentive proceeding of this switch in examine and repair work.
