避雷器主要用于限制由线路传来的雷电过电压或由电气操作引起的操作过电压,是保证电力系统安全运行的重要保护设施之一。简述了碳化硅避雷器和氧化锌避雷器的结构及特性。通过对碳化硅避雷器和氧化锌避雷器进行比较,显示了氧化锌避雷器的诸多优点。氧化锌避雷器在垞城煤矿的应用对电力系统的安全运行起到了重要作用。
Lightning arrester is mainly used to limit the lightning over-voltage from the line or caused by the electrical operation of the over-voltage, is to ensure the safe operation of power systems, one of the important protection. The structure and characteristics of silicon carbide arrester and zinc oxide arrester are briefly described. By comparing silicon carbide arresters and zinc oxide arresters, many advantages of zinc oxide arresters have been demonstrated. The application of Zinc oxide arrester in Tancheng Coal Mine played an important role in the safe operation of power system.
