Isolation switch conductive loop heat insulator flashover and seriously affect the safe operation of the equipment. You can replace static finger pressure springs made of stainless steel spring, stainless steel or galvanized high strength bolts and bolts with a torque wrench to tighten; adjust the contact insertion depth and clean the contact surface, or similar Siemens self-cleaning contacts. At the same time the use of infrared temperature measurement technology on a regular basis to detect fevers conductive parts of puffer type isolating switch, identify problems in time. Rust is the most important issue affecting safe and reliable operation of isolation switch disconnectors, regular anti-rust treatment, transmission parts for each additional lubricant load isolation switch, particularly the use of performance is better than butter, molybdenum disulfide lubricant. Brass sleeve replacement of the steel substrate surface of the sintered bronze plus modified PTFE composite bushings, and end portions of the outer surface of the tin to prevent corrosion. Organizations box with high quality stainless steel products, base isolation switch transformation, drill a hole in the base, the operation of molybdenum disulfide added periodically to ensure that the bearing does not rust. High voltage isolation switch isolation switch _ _ Zhengzhou Xi'an by the Xi'an high Huayi power plant. Xian Huayi Electric Power Equipment Factory (www.xahy.com) strong, credible, in the Xi'an high-voltage circuit breakers and other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Huayi electricity into the brilliant and you work for a better future!
