The main role of isolation switch: 1. for isolated power, high-voltage electric equipment maintenance equipment and high-voltage isolation switch off Jining make room there is an obvious disconnect points visible. 2. isolating switch and circuit breaker with high voltage isolation switch Weifang, as required system operation mode switching operation carried out in order to change the system to run wiring. 3. to turn on or off a small current circuit. 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 that high-voltage electrical equipment and in the maintenance of safe working pressure isolation switch, played the role of isolation voltage can not be used and 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 Dongying pressure isolation switch, the house style and outdoor type, divided by the number of insulating pillars, single-pole, double-column and three-column, the voltage level has optional equipment. Yantai pressure isolation switch | Huayi Electric Power (certified) | high voltage isolation switch provided by Xian Huayi power plant. Xian Huayi power plant (www.xahy.com) is a leader in Xi'an, high voltage circuit breakers, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
