產品作用 Product function

消弧及過電壓保護裝置（簡稱 KWX），是為了迅速消除中性點非直接接地系統弧光接地給電器設備帶來的危害而研制的產品。裝置主要由三相組合式過電壓保護器 DCB、可分相控制的高壓真空接觸器 JZ、微機控制器、高壓限流熔斷器組件 FU 及帶有輔助二次繞組的電壓互感器 PT 等組成。 

Arc suppression and overvoltage protection device (KWX for short) is a product developed to quickly eliminate the harm to electrical equipment caused by arc grounding of neutral point indirect grounding system. The device mainly consists of a three-phase combined overvoltage protector DCB, a high-voltage vacuum contactor JZ which can be controlled by phase separation, a microcomputer controller, a high-voltage current-limiting fuse assembly FU, a voltage transformer PT with an auxiliary secondary winding and the like.
