摘　　要：首先,从动作性能、电气耐受性能和机械性能三个方面阐述了避雷器用脱离器的选择方法;然后,结合相关标准要求和实际运行经验,分析了配电网避雷器和无间隙线路避雷器用脱离器的安装使用方法;最后,归纳出正确进行脱离器选择和使用的方法,指出脱离器的选择应考虑配套避雷器的性能要求、系统接地方式、脱离器的工作原理和安装使用环境条件等,脱离器的安装使用应保证其动作后不影响设备的绝缘水平。This paper firstly states selection method for arrester disconnector in aspects of action performance, electrical performance tolerance and mechanical performance. By combining correspondent standard requirements and practical operation experience, it analyzes installation and application method for distribution network arrester and gapless line arrester disconnector. At last, it concludes correct selection and application method for disconnector and points out that it is necessary to consider performance requirement, system grounding way, working principles and environmental conditions for installation and application of the disconnector when selecting. Meanwhile, it is required not to affect insulation of the equipment after action of the disconnector.
