| | 概述 Summary FN(以下简称FN12-12D负荷开关)是额定电压为12KV,额定频率为50Hz的三相高压开关设备,用于分合负荷电流,空载变压器和电缆充电电流,关合短路电流。配装接地开关的负荷开关,可以承受短时电流。 (以下简称FN12-12(R)D组合电器),是在FN7-12D负荷开关与S□LAJ-12(XRNT□-10)高压限流式熔断器组合在一起的户内高压开关设备。它可以开断直至短路电流的任何电流;负荷开关开断工作电流,熔断器开断短路电流,联合开断工作电流与全短路电流之间的任何电流,同时熔断器通过其碰撞使负荷开关分闸。 It is a three phase H.V switch equipment of 12KV 50Hz for breaking or closing load current. No-load transformer cable charging current and closing short-circuit current.The load switch with earth switch can bear short-circuit current. It is made up of FN12-12D load switch and S□LAJ-12(XRNT□-10)H.V current.Jointly breaking any current between short-circuit current.Meantime.Fuse box make the switch off of with the striker. | 适用范围 Application FN12-12D/负荷开关FN12-(R)D组合电器主要用三相环网或终端供电的市区配电站和工业用电设备中,作负荷控制和短路保护之用。由于组合电器对变压器等电器设备的保护作用比用断路器更可靠,特别适用于环网,比辐射代单元和箱式变电站。 It is used in the ring network city distribution and industrial equipment of 12KV and three-phase AC 50Hz to cortrol load and short-circuit.Because the switch with fuse protecting transformer etc more reliably than circuit breaker .It is especialy suitable for ring network clouble radial distribution and package substtion. | 产品采用标准 Standard a、GB3804-90《3~65KV交流高压负荷开关》 b、GBXXX-XX《交流高压负荷开关-熔断器组合电器》(等效IEC420-1990) c、GB1995-89《交流高压隔离开关和接地开关》 a、GB3804-90《3~65KV AC H.V Load switch》 b、GBXXX-XX《AC H.V load switch with fuse box》(the same IEC420-1990) c、GB1995-89《AC H.V isolate switch and earth switch》 | 正常工作环境 Normal Serviec Condition A、周围空气温度 不高于 40oC 不低于-25oC; B、海拔不超过1000米; C、相对湿度,月平均值不大于90%,日平均值不大于95%; D、周围空气应不受腐蚀性、可燃性气体及水蒸汽体等明显污染; E、无经常性的剧烈运动; F、耐污秽等级:Ⅱ级。 如使用条件超过上述规定,由用户与制造厂商协商确定。A、The ambient air temperatrue : Max: 40oC.
