請求の範囲第(1)項記載の抵抗付接地開閉器。[Claims for Utility Model Registration] (1) Grounding for discharging residual charges in a high-voltage conductor used in a miniature switchgear in which a switch is installed in a closed container filled with an insulating and arc-extinguishing medium. In the device, a fixed contact connected to a high voltage conductor of the reduced type switchgear and a movable contact provided substantially coaxially with and facing the fixed contact and connected to a ground potential are configured to be able to connect and separate. At the same time, a shield electrode having a hole through which the movable contact passes is connected to the high voltage conductor via a resistor on the side facing the movable contact of the fixed contact, and the high voltage conductor is grounded by the movable contact. In this case, the voltage charged in the high-voltage conductor causes a preliminary discharge to occur between the movable contact and the shield electrode, and after discharging the residual charge through the resistor, the high-voltage conductor is directly grounded. A grounding switch with a resistor, characterized in that it is configured to. (2) The earthing switch with a resistor according to claim (1) of the utility model registration claim, characterized in that an arc-resistant electrode is fixed to the discharge surface of the movable contactor and the shield electrode.
