Isolation switch disconnectors are used in high-voltage switching equipment up to an appliance, as the name suggests, is isolated from the role in the circuit itself working principle and structure is relatively simple, but due to the use of large, high reliability requirements of the power plant impact design, build and safe operation are larger. The main features of the knife is the ability to isolate non-interrupter switch, only in the case of no load current points, co-circuits. Circuit breakers and disconnectors for the difference? What is the difference referred to? Circuit breaker interrupter device, it can bring a load circuit breaker operation, not only to operate the load current, but also to operate fault (short circuit) current; circuit breakers have a good package, it is simply to observe the breaker, it is not visually determine in the closed or open position. Disconnectors no interrupter device, although the rules of order that can be operated in the load current is less than 5A occasions Shenzhen isolation switch, but it does not belong with the overall load operation; but the simple structure of Guangzhou isolation switch disconnectors, can see at a glance from the appearance of its Liuzhou isolation switch operating status, a significant overhaul break point. In use, the circuit breaker referred to "switch", disconnector referred to as "knife" In use, the two often used in combination. Disconnectors _ Shenzhen 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.
