1、摘要根据设计任务书的要求,本次设计为110kV牵引变电站的防雷设计,变电站是电力系统中重要组成部分,而且变电站的电气部分要装设合理的避雷装置和接地装置,因此,它是防雷的重要保护对象。如果变电站发生雷击事故,将造成大面积的停电,给人民生活和社会生产带来重大不便,还有可能给国家造成大经济损失,这就要求防雷措施必须十分可靠变电站的防雷设计应做到设备先进、保护动作灵敏、安全可靠、维护方便,在此前提下,力求经济合理的原则。本次设计,主要对变电站的主要设备进行选择,重点设计变电站的防雷部分,包括变电站进线段保护、防直击雷、防感应雷以及变电站二次设备的防雷。通过对
2、各种避雷器的性能对比,结合变电站实际情况,确定变电站的避雷器的选择,并考虑变电站控制系统的防雷,提出防雷方案。氧化锌避雷器以其优越的性能,越来越受到电力行业的关注。本次设计,将结合氧化锌避雷器性能的优点,并结合变电站设计的情况,讨论氧化锌避雷器在变电站中的应用前景。关键词:变电站,避雷器,防雷保护IAbstractAccordingtotherequirementofthedesignspecification,thisdesignisa110kVtractionsubstationlightningprotectiondesign.Substati
