Isolation switch refused points, closing what should I do? A: (1) due to the axle pin off, wedge bolt exit, cast iron fracture mechanical failure, or because of an electrical circuit fault may occur Arbor touch with the operating mechanism, causing the isolation switch refusal closing, then use insulated rod operation or isolation in ensuring the personal safety of the switch, turn each phase isolation switch shaft with a wrench. (2) refusing to trip. When the isolation switch will not pull out when Anyang isolation switch, such as the Department of actuator is ice frozen, you can gently shake and observe the various parts of the support insulator and institutions to deformation and displacement occur according to where to find the obstacles location. If the obstacle location contact part occurs in isolation switch should not be forced to pull Shiyan isolation switch, otherwise support insulator may be affected by damage caused by a serious accident, then the only way to change the operation of the equipment to be addressed. 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, but it does not belong with the overall load operation; but isolating switch disconnectors Suizhou simple structure, can see at a glance from the appearance of its operating status, 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. Anyang isolation switch, isolation switch, the power provided by the Xi'an Huayi Huayi power plant. Xian Huayi power plant (www.xahy.com) strong, credible, in Xi'an high-voltage circuit breakers and other industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Huayi power and you hand into the brilliant, for a better future!
