Disconnectors (commonly known as "Knife"), generally refers to high-voltage isolation switch, which rated voltage 1kV and above disconnectors, commonly referred to as isolation switch Guizhou 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 shut-off capability, 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. The correct order of operations isolation switch: (1) First isolation switch in the operation, you should first check the appropriate circuit breaker in the off position indeed, in order to prevent a negative Hera, co-isolation switch. (2) line stop, when the power is in the order must pull together isolation switch. When a power outage, you must first pull circuit breakers, disconnectors pull the line-side isolation switch, then pull the bus side of the isolation switch. Power transmission and power operation sequence in reverse order. This is because when the malfunction occurred, according to the above procedure can reduce the scope of the accident, to avoid artificially expanded to make the bus accident. (3) operations, such as found seriously damaged insulator, isolating switch gear lever serious damage and other serious defects, may not operate. (4) isolation switch isolation switch when operating the Tibet Autonomous Region, should be on duty at the scene-by-phase check points, closing position, over the same period, the contact depth contacts and other projects, to ensure the correct operation of the isolation switch, the correct position. (5) should generally be operated isolating switch in the main control room. When the remote control electrical operation failure in the field can be manually or electrically operated locally Tianjin isolation switch, but must seek permission from owners or technical person in charge, and in the case of on-site supervision of the situation can take place. (6) disconnectors, grounding switch and circuit breaker between the installation to prevent misuse of electrical, electromagnetic and institutions locking device. Switching operations, according to a certain order. If the locking device malfunction or disconnectors and earthing switches does not operate properly, you must strictly in accordance with the requirements of lockout condition check the appropriate circuit breakers, disconnectors position status only after checking the correct order to lift the lockout operation. Tibet Autonomous Region, 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.
