Porcelain fracture failure. In 2005, Xuzhou power grid twice porcelain fracture fault isolation switch wholesale, once the operation is running, once the wiring in the construction process, the breaks are glued at the porcelain and the flange. Porcelain fracture related to both product quality gas pressure isolation switch, but also with the overall quality and method of operation of the relevant isolating switch. Control may result in improper porcelain porcelain pieces cooked, dense uneven and cement loading problem of the poor in the firing process, combined with strict quality control measures disconnectors, resulting in poor quality of individual vases are assembled product, put into operation pose a great threat to the security. The operator at the time of division and isolation switch operating improper methods, excessive force are likely to cause damage porcelain. In addition, in 2005 and 2004 also occurred knots 8 500kVSOPLT type knife support insulator cracking defects. Institutional issues. Institutional issues showed malfunctioning load isolation switch, such as tripping or sub-switch is not in place, tend to occur in switching operation, the safe operation of the system. Since the mechanism box sealing bad or corrosion caused by water bodies severe corrosion, lubricate dry, operation resistance increases, the difficulty of operating at the same time, will occur damaged parts, such as transmission gear broken, connecting rod twist like. Transmission difficulties. Transmission of corrosion caused by transmission isolation switch resistance, even rejecting Resist, such as in the operation of a base bearing rust had appeared, the situation can not be operated, which is the spindle copper sets of dry transmission parts, bearing dirt, grease dry caused. Disconnectors wholesale | Hangzhou isolating switch | 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.
