这些Driescher室内开关设备是专门为铁路应用而设计的。它们符合en50152 -2的规范。根据各自的设计,1杆开关可用于15 kV至27.5 kV的额定电压范围,以及400 a至4000 a的额定电流范围。参考电压:25kv;该设备可安装在海拔1000米以上的地方。在海拔1000米以上的地方,开关柜的额定绝缘等级必须相应调整。这些开关设备是为在符合en62271 -1的正常工作条件下使用而设计的。根据本规范,下列限值适用:环境温度:最大值。值:+40°CAllgemein这些Driescher室内开关是专门为铁路应用设计的。 They meet the specifications according to the EN 50152-2. The 1-pole switches are designed for a rated voltage range from 15 kV to 27.5 kV and a rated current range of 400 A to 4000 A. Fittings The switch disconnectors are basically fitted with a stored energy mechanism for rapid making and braking. The current carrying components are made of electrolytic copper with electro-silver plating in compliance with QTL 0200. All steel parts have been given an electro-plated coating which provides excellent corrosion resistance. Every switch is provided with an earthing screw
