| TBP三相组合式过电压保护器（以下简称保护器）是专用于3～35kV中压系统，保护系统内部操作过电压（主要是真空开关强制截流过电压，也包括多次重燃过电压和三相开断不同步产生的过电压）对电气设备侵害的产品。其核心工作原理是采用放电间隙给氧化锌阀片分压的方式，降低产品的操作冲击保护残压，实现对操作过电压的保护；同时采用四星型接法（俗称三叉戟式接法），设置公共中性点，实现对相间过电压的快速响应，有效防止三相负载出现相间绝缘击穿。 TBP three-phase combined overvoltage protector (hereinafter referred to as the protector) is dedicated to the 3 ~ 35kV medium voltage system, internal overvoltage protection system (mainly forced vacuum switch overvoltage, including restrike overvoltage and overvoltage fault three-phase open synchronous generation) of electrical equipment against products. The core principle is the www.huizhuanyao5.com.cnwww.gzdebon.com.cnwww.dianLiwuzi.com.cnwww.btwujin.cnwww.bjsrxhsart.c nwww.huafuly.cndischarge gap to Zinc Oxide valve pressure, reduce the product operation impact protection residual voltage, to realize the protection of overvoltage; at the same time using the four-star connection method (commonly known as Trident connection), set the public neutral point, to achieve rapid response and effective overvoltage. To prevent the three-phase load occurs due to insulation breakdown. 由于保护器其主要工作元件是氧化锌阀片，与避雷器类似，所以有些地方也将其称为组合式避雷器。但是，事实上两者的作用是完全不同的。避雷器以防雷为主要目的；而保护器虽然也可以用于防雷，但主要是与真空开关配套使用，防止操作过电压侵害的。The main work is the Zinc Oxide element protection valve, similar to lightning arrester, so in some places it is called the combined arrester. But in fact, the effect is completely different. The main purpose of lightning arrester; and although the protector can also be used for lightning protection, but mainly supporting the use of vacuum switch, to prevent overvoltage infringement. |
