GIS Earthing switch for Gas Insulated Switchgear with measurement function of ground safety

摘要

The present invention relates to a grounding switch for GIS having a grounding safety measurement function, and more particularly, a grounding resistance measuring unit for measuring the grounding resistance of the grounding system and a contact state sensing unit for detecting the contact state of the electrode is further included. The present invention relates to a grounding switch for GIS equipped with a grounding safety measurement function that can guarantee the safety of the system and prevent power system failures and accidents. The present invention, the opening and closing operation unit for grounding or ungrounding the power line by intermittent electrical connection between the movable electrode connected to the grounding system and the fixed electrode connected to the power line; A ground resistance measuring unit connected to the ground system and measuring ground resistance of the ground system; And a control unit for controlling the operation of the opening and closing operation unit and the ground resistance measuring unit; GIS grounding switch with a ground safety measurement function, characterized in that consisting of.
