High voltage isolation switch according to the different installation methods can be divided into outdoor and indoor high-voltage isolation switch high-voltage isolation switch. Outdoor high-voltage isolation switch means to withstand wind, rain, snow, filthy, condensation, ice and heavy frost and other effects, suitable for high-voltage isolation switch installed on the terrace for use. Can be divided according to their different single-pole isolation switch (single-column disconnector), double-column disconnectors (double-column disconnector), three-column disconnectors (three-column disconnector) insulation pillar structure. One single overhead busbar disconnectors column directly below the vertical space used as electrical insulation fracture, and therefore well-being of 110kv high voltage isolation switch, with a distinct advantage, and that is saving footprint Shangluo 110kv high voltage isolation switch, reducing the connection of 110kv high voltage wire Tongchuan isolation switch, while switch on state particularly clear. In case after EHV transmission and substation disconnectors single column, saving an area of ??effect is more significant. Isolating switch contact parts overheat in operation is what causes it? A: The isolation switch in the operation of overheating, overloading mainly contact resistance increases, the operation did not completely closed due.
