| 线路过电压保护器区别 Difference of line overvoltage protector 1）过电压保护器和避雷器都有抑制过电压保护电气设备的作用。 2）在电力系统中的过电压： 暂时过电压（工频过电压、谐振过电压）、操作过电压、雷电过电压。 3）过电压保护器有无抑制雷电过电压的作用就要看其设计参数了。避雷器不仅仅为雷电过电压的保护。避雷器在电力系统中的别称为过电压保护器，现在普遍使用的是氧化锌避雷器（moa）。 1) overvoltage protectors and surge arresters have the function of restraining overvoltage to protect electrical equipment. 2) overvoltage in power system: temporary overvoltage (power frequency overvoltage, resonant overvoltage), operation overvoltage and lightning overvoltage. 3) whether the overvoltage protector has the function of suppressing lightning overvoltage depends on its design parameters. The lightning arrester not only protects the lightning overvoltage. The lightning arrester in the power system is also known as an overvoltage protector, and now the Zinc Oxide arrester (MOA) is commonly used. |
