PGS SF6气体绝缘杆式负载开关适用于额定电压12kV、额定电流630A、额定频率50Hz的架空线路配电系统。当电路出现故障时,能及时隔离故障段,恢复非故障段的供电。本产品有手动、电机、遥控三种操作方式。实现了配电网的自动化功能。描述1。•标准气体压力:0.035 MPa(即0.35kg•f/cm2•G, 20℃);•配有气体压力表,可监测气体压力。压力开关是另一种选择,当气体压力低于设定值(0.1~0.2kg•f/cm2•G)时,可操作电路锁定;•为了防止外壳爆炸和内部物体散射,采用了防爆装置。防爆板的破裂压力为1.0 ~ 2.0 kg•f/cm2•G,在操作手柄的另一侧安装防爆装置,确保操作人员安全; 2. Casing and sealing: • The interrupter and the mechanism are sealed in a tank which is filled with SF6 gas, the casing is made of 3mm thick stainless-steel plate, welded by argon arc welding art, and being anti-rust treated; • There are 3 layer of special NBR (nitrile butadiene rubber) sealing material between both of the porcelain bushing and the switch, and, the operating handle and the operating mechanism; • Installation bracket is equipped with the switch, there are lifting hook, bolts, bolt-holes on the casing, and all installation metal parts are made of galvanized steel parts;
