产品用途和特点
JW10系列高压交流接地开关是三相交流频率50Hz/60Hz的户外高压输电设备,用于释放被检修线路和设备的静电荷,对检修的母线与断路器等高压设备实行电气安全接地,使线路中有明显可见的接地开合标志,保证停电检修人员的人身安全。通常在采用单柱垂直断口隔离开关的场所,用它对上层母线进行接地。
JW10系列接地开关可以附装在GW4C、GW6B、GW7B、GW22B、GW23B等型号的隔离开关上,也可以构成独立的接地开关。JW10-126、145、252型采用SRCS型人力操动机构或SRCJ3型电动机操动机构进行三极联动操作。JW10-363、550型接地开关配用SRCJ2型电动机操动机构进行单极操作,也可实现三极电气联动。
本接地开关加辅助回路、引弧触头后具有高于国家标准及行业标准B类规定的开合感应电流的能力,适用于同塔双回路平行架空输电线路中变电站进出线端接地。
