Abstract Disconnecting switch is one of the largest, the most widely used, and the most important high voltage electrical equipment in power system, after long time operation, disconnecting switch common overheating, a static contact rotating part jam, switching is not in place and other defects. Maintenance personnel usually combined with the inspection of static contact is loosing, lubrication and cleaning. This paper introduces the working principle of contact maintenance device, and the disconnecting g switch contact device charged maintenance, regular contact charged maintenance, make contact resistance disconnecting switch values within the normal range, maintenance of prolonged isolation switch contact maintenance cycle, prolonged isolation switch service life, improve the reliability of equipment and power grid.
