Isolation switch is mainly used to require high-voltage power distribution equipment parts and live parts reliably isolated to ensure the safety of maintenance work. Chang Lu isolation switch contacts all in Luoyang air pressure isolation switch, with a clear break point, there is no isolation switch interrupter device, and therefore can not be used to cut off the load current or short circuit current, otherwise under high pressure, breaking point will produce a strong arc, and is difficult to self-extinguish, and may even cause arcing (relative or phase short circuit), burning equipment, endangering the safety of Zhengzhou high voltage isolation switch, which is called "negative Hera isolation switch" in a serious accident. Isolating switch can also be used for some of the circuit switching operation to change the system runs. For example: Changsha high-voltage isolation switch, you can run the circuit switched from a bus in double busbar circuit with isolation switch to another bus. At the same time, can also be used to operate a number of small current circuits. Commonly used high-voltage isolation switch has GN 19 - 10 high-voltage isolation switch, GN 19 - 10 C, 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 Yiyang pressure isolation switch, Huayi Electric Power (certified), high-voltage isolation switch from Xi'an, China Instrument power plant available. 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. Huayi power in leadership with the staff warmly welcome all inquiries negotiations to create electricity Huayi a better future.
