金属氧化物避雷器用脱离器的关键技术研究及标准制定的建议

脱离器可以将故障避雷器隔离出运行系统,并给出明显、永久的脱离标示,是金属氧化物避雷器的主要附件之一。IEC60099-4、GB11032等避雷器标准规定了脱离器的技术要求和试验方法。但是,在实际运行中脱离器出现不少质量问题,严重影响到电网的安全。我们在脱离器工作原理的基础上,对其关键技术进行了较深入的研究,建议尽快制定金属氧化物避雷器用脱离器的行业标准。

Study of Key Technologies of Disconnector Used in Metal Oxide Surge Arrester and Proposals for Standard

A disconnector can disconnect an arrester from the system in the event of arrester failure and give visible and permanent indication of disconnection.It is one of the key accessories of metal oxide surge arresters.The technical requirements and test methods for disconnector are specified in arrester standards such as IEC60099-4,GB11032 and etc..However,a lot of quality problems have arisen in actual operation,which seriously affected the safety of the grid.The key technologies of disconnector are further researched based on its operation principle.It is recommended to develop an industry standard of the disconnector used in metal oxide surge arresters as soon as possible.
