Description

TECHNICAL FIELD

[0002] Gas insulated metal enclosed switchgear (GIS) has the advantages of small floor area, high operation reliability, long maintenance cycle, etc., and has been more and more widely used in power system, especially in high voltage level power grid. But there are the following problems in the process of use:

[0003] The switching contact may not match the actual opening and closing state of the contact, or the opening and closing may not be in place, resulting in the failure of the electrical lock mechanism. If the GIS is operated in this state, a high voltage switch operation accident will occur. As one of the key units in GIS, the isolation switch is operated most frequently, and in a large number of operation processes, the contact will be continuously worn under the impact of mechanical closing force and the stress between contacts, and often appears the situation of contact finger plating crack, peeling, etc., resulting in poor contact of the contact. When the contact is not in good contact, the contact mode will change, and at this time, when the current flows through the contact, the electric force will be generated between the contacts, thereby causing abnormal vibration, and long-term vibration may cause the bolt to loosen, causing GIS gas leakage and pressure reduction, thereby causing an accident. At present, the opening and closing state of the switch is mainly monitored by regular inspection, but this way is not only low in efficiency, but also cannot monitor the opening and closing state of the switch in real time, and it is difficult to prevent the occurrence of high voltage switch operation accident.
