过电压保护器是起到一个保护什么产品的作用？过电压保护器是用来限制雷电过电压和操作过电压的，是一种先进的，新型的过电压保护设备。过电压保护器的全称叫做“三相组合式过电压保护器”。过电压作保护器为一种比较先进的保护设备，主要用于保护发电机、变压器、真空开关、母线、电动机等电气设备的绝缘，避免遭受过电压的损害。它也可以起到避雷器的一部分作用，但又是传统的避雷器性能上不能相比的。
What product does an overvoltage protector protect? Overvoltage protector is an advanced and new type of overvoltage protection device used to limit lightning overvoltage and operational overvoltage. The full name of overvoltage protector is "three-phase combined overvoltage protector". Overvoltage protector is a relatively advanced protection device mainly used to protect the insulation of electrical equipment such as generators, transformers, vacuum switches, busbars, and motors from damage caused by overvoltage. It can also serve as a part of a lightning arrester, but its performance cannot be compared to traditional lightning arresters.
过电压的主要的工作原理是采用放电间隙给氧化锌阀片分压的方式，来降低操作冲击，保护残压，实现对操作过电压的保护。此产品已经广泛的应用在电力 、化工、煤炭、建筑、电气化铁道等行业。ZB-TBP型过电压保护器，可以使电力系统中的电动机，真空开关，变压器以及并联补偿器等电器设备免遭受大气过电压、特别是相间过电压的相对较好的保护装置。
The main working principle of overvoltage is to use discharge gaps to divide the voltage of zinc oxide valve plates, in order to reduce operational impact, protect residual voltage, and achieve protection against operational overvoltage. This product has been widely used in industries such as power, chemical, coal, construction, and electrified railways. The ZB-TBP overvoltage protector is a relatively good protection device that can protect electrical equipment such as motors, vacuum switches, transformers, and parallel compensators in power systems from atmospheric overvoltage, especially phase to phase overvoltage.
