Description

ZW20-12F/630A 10KV High Voltage Circuit Breaker Intelligent Outdoor Pole-Mounted Recloser


Overview

ZW20-12 outdoor pole vacuum circuit breaker is a new generation product developed by our company according to the new requirements of primary and secondary fusion complete set of on-column switch accessto the network.Unified procurement,mass production.The switch has a compact structure,a reasonable layout,and complete functions.All indicators meet the requirements of the primary and secondary fusion of the State Grid.It adopts unified parameter protection CT,zero sequence CT and zero sequence voltage sensors.It has a wide measurement range,high measurement accuracy,and reliability.High characteristics,complete analog quantity is convenient for accurate determination of various faults on the line.

The zw20-12 switch body is a common box type,which is vacuum insulated SF6 gas insulated.The box body adopts gas sealing,explosion-proof, insulating structure technology,and the overal ealing performance is excellent.The SF6 gas flled inside does not leak and is not affected by the external environment.Its spring operating mechanism has been miniaturized and optimized for performance,and its action reliability is much higher than that of the traditional domestic spring mechanism.Buit-in1 set of EVT ECT (three-phase voltage,current,zero-sequence voltage,curent used for measurement,measurement,protection).Two external electromagnetic single-phase power supplies PT,10/0.1/0.22kV.
