供应hgw4隔离开关

户外高压隔离开关说明（explanation）：gw9-12型户外高压职责离开关是单相交流50hz高压开关设备，用于10kv的电力系统中，作为有电压无负载的情况下接通或分断电源使用。本隔离开关用绝缘棒进行操作。正常使用条件（normalserviceconditions）:*海拔高度不超过1000米。*周围空气温度：上限+40℃，下限一般地区-30℃，高寒地区℃。*风压不超过700pa。（相当于风速34m/s）。*地震烈度不超过8度。*无频繁剧烈震动场所。*普通型安装场所应无严重影响隔离开关绝缘和导电能力的气体、蒸气、化学沉积、盐雾、灰尘及其它爆炸性、侵蚀性的物质。防污型适用于污秽地区，但不应有引超火灾及爆炸物质。技术参数（technicaldata)：hgw9-12(w)kv品型号type额定电压ratedvoltagekv额定电流ratedcurrent(a)4s热稳定电流4sheatsteadycurrent(a)动稳定电流shocksteadycurrent(a)冲击耐压（kv）impulsewithstandvoltage工频耐压（kv）power-frequencywithstandvoltage相对地relativelyearth断口间betweenfracture相对地relativelyearth断口间betweenfracturehgw9-12/40012400125003150075853842hgw9-12/60012600125003150075853842hgw9-12kv：产品型号type额定电压ratedvoltagekv额定电流ratedcurrent(a)4s热稳定电流4sheatsteadycurrent(a)动稳定电流shocksteadycurrent(a)冲击耐压（kv）impulsewithstandvoltage工频耐压（kv）power-frequencywithstandvoltage相对地relativelyearth断口间betweenfracture相对地relativelyearth断口间betweenfracturehgw9-12/40012400125003150075853842hgw9-12/63012630125003150075853842hgw9-12/1000121000125003150075853842hgw9-15g/40015400125003150075853842hgw9-15g/63015630125003150075853842hjdw2-0.5kv产品型号type额定电压ratedvoltagekv额定电流ratedcurrent(a)breakmgcurrent(a)hjdw2-0.5kv/5000.550030~500hjdw2-0.5kv/8000.580030~800jdw2-0.5kv产品型号type额定电压ratedvoltagekv额定电流ratedcurrent(a)breakmgcurrent(a)jdw2-0.5kv/5000.550030~500jdw2-0.5kv/8000.580030~800gwr1-0.5kv熔片额定电压120a150a220a300a360a470a600a熔片规格0.150.200.300.500.600.800.90配变压器容量80100150180-200250315-320400gw4-12/17.5/40.5分类型号type额定电压ratedvoltage(kv)额定电流ratedcurrent(a)隔离开关接地开关接地开关额定峰值耐受电流ka额定短时耐受电流ka额定峰值耐受电流ka额定短时耐受电流ka一般型(防污型)12400-10005020508020(4s)31.5(4s)不接地单接地双接地gw4（a）-126型号type额定电压ratedvoltage(kv)额定电流ratedcurrent(a)动稳定电流（峰值）ka(peak)layn额定热稳定电流kaith额定热稳定间stimeofratedthermalstability1min工频耐压kv1minpowerfrequencywithstandvoltage雷电冲击耐压kvlightningimpulsewithstandvoltage单极重量weightofsinglepole配用机构operatingmechanism隔离开关disconnector接地开关earthingseitchgw4(a)-126(d)/63012663050204210520230cs14gcs17gcs14gcs17ggw4(a)-126(d)/63012663050204210520230cs14gcs17gcs14gcs17ggw4(a)-126(d)/63012663050204210520230cs14gcs17gcs14gcs17ggw5型号type额定电压ratedvoltage(kv)额定电流ratedcurrent(a)动稳定电流（峰值）ka(peak)layn额定热稳定电流kaith额定热稳定间stimeofratedthermalstability1min工频耐压kv1minpowerfrequencywithstandvoltage雷电冲击耐压kvlightningimpulsewithstandvoltage单极重量weightofsinglepole配用机构operatingmechanism隔离开关disconnector接地开关earthingseitchgw4(a)-126(d)/63012663050204210520230cs14gcs17gcs14gcs17ggw4(a)-126(d)/63012663050204210520230cs14gcs17gcs14gcs17ggw4(a)-126(d)/63012663050204210520230cs14gcs17gcs14gcs17ggw13-40.5/72.5/126(w)/630型号type额定电压ratedvoltage(kv)额定电流ratedcurrent(a)额定短时耐受电流karatedshort-timewithstandcurrent额定短时需受时间srateddurationofshort-circuit额定峰值耐受时间karateddurationofpeak1min工频耐压kv1minpowerfreqwithstandvoltage雷电冲击耐压kvlightninimpulsewithstandvoltage接线端子额定静拉力nratedstaticpullingpowerofwiringterminalgw13-40.5(w)40.56302045095185750gw13-72.5(w)72.563020450140325750gw13-126(w)126630204501854501000gw1-12g(d)项目单位参数备注额定电压kv12额定电流a630．1250额定峰值耐受电流ka50．100接地闸刀与主闸刀相同4s额定短时耐受电流kv20．40型号结构型式电流等级gw1-12g/1250不接地1250agw1-12g（d1）/1250动触头接地1250agw1-12g（d2）/1250静触头接地1250a
