Power plants and high-voltage isolation switch is important substation electrical system electrical switches, need and supporting the use of high voltage circuit breakers, its main functions are: to ensure the safety of high-voltage electrical appliances and equipment during maintenance work, acts isolation voltage can not be used with cut into breaking load current and short-circuit current, can be used not only to produce some powerful arc switching operation, that it does not have the interrupter function; according to the installation site is divided into different, inside and outside type style Wuhan high voltage isolation switch , divided by the number of insulating pillars, single-column Heze pressure isolation switch, double-column and three-column, the voltage level has optional equipment. Commonly used high-voltage isolation switch has GN 19 - 10, GN 19 - 10 C high-voltage isolation switch, corresponding to similar older products GN 6 - 10, GN 8 - 10. Now with GN 19 - 10, for example, includes the following components: a conductive part 2, part 3 insulation, transmission part 4, the base portion of sunlight pressure isolation switch high-voltage isolation switch _ _ Huayi electricity from Xi'an Huayi power plant available.
