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 closing isolating switch disconnectors refuse, then use insulated rod operation, or in the case of Nanyang ensure the safety isolating switch, turn each phase isolation switch shaft with a wrench. (2) refusing to trip. When the isolation switch will not pull out when the actuator is the case of the ice to freeze, you can gently shake and observe the various parts of the support insulator and institutions in order according to where the deformation and displacement, identify obstacles location. If the obstacle location occurs in the contact portion isolating switch should not be forcibly opened, otherwise the 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. . Rust is the most important issue affecting safe and reliable operation of the isolation switch disconnectors Shiyan, regular anti-rust treatment, transmission parts for each additional lubricant, particularly the use of performance than butter molybdenum disulfide lubricant. Brass sleeve replacement for steel substrate surface modified PTFE composite sintered bronze bushings plus, and the ends of the outer surface of tin to prevent corrosion. Agencies box with high quality stainless steel products, base isolation switch transformation, drill a hole in the base, running regularly add molybdenum disulfide, ensure bearing does not rust. Huaibei disconnectors, Huayi Electric Power (certified), isolating switch is provided by Xian Huayi power plant.
