| 过电压保护器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，也包扩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;过电压保护器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。 Over-voltage protector internal operating overvoltage protection system (mainly vacuum switch forced closure overvoltage, also including the renewed overvoltage and three-phase overvoltage produced by the breaking out of sync on electrical equipment of the product. Its core principle is to use discharge gap to zinc oxide valve pressure, reduce the operation impact to protect the residual pressure of the products, realize to operating over-voltage protection; Over-voltage protector at the same time using four star connection (commonly known as the trident connection), set up public neutral point, and realize the fast response, overvoltage effectively prevent the three-phase load and insulation breakdown. |
