The isolation switch control connections with the corresponding circuit breaker lockout, which can effectively prevent a negative Hera, co-isolation switch. However, operating the bus side and line-side isolation switch disconnectors, due to human causes, it may cause reverse order of operations, which is a switch, one of the causes of the accident Switch Operation not permitted in principle, but also the power system. To prevent the isolation switch operating in reverse order, for not using anti-error program lock factory, station Jiaxing pressure isolation switch, isolation switch control of its original wiring to be improved to prevent misuse, reduce unnecessary accidents. Isolation switch operating mechanism of Wenzhou high-voltage isolation switch, transmission machinery should adjust Hangzhou high-voltage isolation switch, so that open and close operations can be normal, no anti-Jin phenomenon. But also to meet the requirements of the three-phase period, namely the three-phase moving contact points closing at the same time isolating switch action, different phase deviation should be less than 3MM. Furthermore, when in the closing position, the movable contact have enough plunging depth, in order to ensure compliance with the requirements of the contact area, but does not allow too far together, the requirements from the movable contact to the stationary contact base has 3 5MM voids, otherwise co The static contact support insulator crack when excessive brake. When in opened position, the contacts between the movement to have enough distance to effectively isolate the live parts, the distance should not be less than 160MM, or move between opened contacts with static contact angle of not less than 65 degrees . Wenzhou high-voltage isolation switch | Huayi Electric Power (certified) | 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.
