Isolation switch configuration 1, both sides of the circuit breaker isolation switch should be configured so as to form a clear fracture and power isolation in the circuit breaker maintenance. 2, neutral grounding transformer general, by isolating switch shall be grounded. 3, on the bus arresters and voltage transformers, isolation switch should be combined with a group, to ensure the safety of electrical maintenance and high voltage busbar disconnectors Tongchuan production, each group 1-2 grounding switch should be installed on the bus. 4, connected to the transformer neutral point lead or arrester installed without disconnecting switch. 5, when the side of the feeder line of the user is no power, leading to the user that the circuit breaker can not be installed side isolation switch. However, in order to prevent over-voltage lightning can also be installed. 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, high voltage switch is one of the most used appliances in Weinan high voltage electrical isolation switch production, which itself is the working principle and 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 pressure isolation switch, 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. Weinan high-voltage isolation switch production _ Huayi Electric Power (certified) _ Xi'an high-voltage isolation switch provided by 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.
