Description

GIS equipment operating handle safety control structure

Technical Field

The utility model relates to the technical field of safety measures of electric power systems, in particular to a safety control structure of an operating handle of GIS equipment.

Background

GIS in the power system refers to a gas-sealed isolating switch station, and the general sealing gas is sulfur hexafluoride gas, so the GIS is also called a sulfur hexafluoride sealed combined electrical appliance. The GIS is composed of a circuit breaker, a disconnecting switch, an earthing switch, a mutual inductor, a lightning arrester, a bus, a connecting piece, an outgoing line terminal and the like, all the equipment or components are sealed in a metal grounded shell, and sulfur hexafluoride insulating gas with certain pressure is filled in the metal grounded shell for insulation. The GIS device is formed by assembling a plurality of independent air chambers.

The operating handles of a plurality of GIS spaced high-voltage switches and knife switches are usually concentrated in one box body, and each operating handle cannot be locked independently. When equipment is overhauled, only one interval in the box body is overhauled. During the maintenance, the maintenance equipment (also including the operating handle in the box) needs to operate the operating handle at the maintenance interval at any time according to the maintenance requirement, but the operating handles at other operation intervals cannot be operated at will. Otherwise, serious personal and equipment accidents are caused, and the safe operation of the power system is directly threatened. The above-mentioned interval is an electrical interval, and in an electric power system, the electrical interval of a substation refers to a complete or relatively complete loop.

Present GIS equipment during operation generally can use electrician's adhesive tape to paste operating handle, perhaps directly hangs the warning sign on operating handle, avoids the corresponding handle of maloperation, but the method that above-mentioned two kinds of handles prevent the maloperation can only play the suggestion effect, can not realize forcing shutting operating handle's purpose, and electrician's adhesive tape and the warning sign that hangs drop easily, lose the suggestion effect.
