概述Product Structure

FZW28-12F型户外用户分界真空负荷开关(FFK),为额定电压12kV,三相交流50Hz的户外柱上配电开关设备。采用真空灭弧和SF6气体作对地及相间绝缘介质，是一种免维护负荷开关。

本产品符合：GB3804《高压交流负荷开关》及GBT11022《高压开关设备和控制设备标准的共用技术要求》。该户外分界真空负荷开关(负荷开关本体与FDR-01型故障检测控制器)具备故障检测功能，保护控制功能和通讯功能，安装于10kV配电线路用户进线的责任分界点处，也可以适用于符合要求的分支线连接处与前级重合器配合，可实现自动切除单相接地故障和自动隔离相间短路故障，并能快速定位故障点。

Users boundaries FZW28-12F Outdoor vacuum load switch (FFK),rated voltage 12kV,three-phase AC 50Hz outdoor column distribution switchgear.Vacuum interrupter and SF6 gas against ground.interphase dielectric,is a maintenance-free load switch.

This product complies with:GB3804 "AC high voltage load switch"and GBT11022 "high-voltage switchgear and control equipment standardcommon technical requirements."The boundaries of outdoor vacuum load switch (negative dutch switch body and FDR-01-type fault detectioncontroller)with fault detection,protection and control functions and communication functions,mounted on responsibility 10kV distribution line atthe demarcation point into the line user,you can also applicable to meet the requirements of the branch line connection in conjunction with thepre-coincidence,automatic removal of single-phase ground fault isolation and automatic phase short circuit fault,and can quickly locate the pointof failure.
