Disconnectors (commonly known as "Knife"), generally refers to high-voltage isolation switch disconnectors Jilin, which rated voltage 1kV and above disconnectors, commonly referred to as isolation switch, high voltage switch is one of the most used appliances in appliances It works by itself and the structure is relatively simple, but due to the use of large, high reliability requirements, the impact of the substation, power plant design, build and safe operation are larger. The main features of the isolation switch is not extinguishing capability, only in the case of no load current points, co-circuits. Isolating switch for voltage levels used for electrical connections or to change the line or equipment and power isolation, it does not have the ability to Dalian isolation breaker switch, only the first off the line with other devices after the operation. Usually an interlocking means with a load when the erroneous operation prevention switch is sometimes necessary to prevent the pin disconnect switch magnetic force large fault. Movement isolation switch contacts should be aligned, otherwise the closing time will be next to the hammer, so that after closing and moving contacts the contact surface pressure is uneven, resulting in poor contact. Qinhuangdao disconnectors, Huayi Electric Power (certified), isolating switch is 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. Huayi power in leadership with the staff warmly welcome all inquiries negotiations to create electricity Huayi a better future.
