徴とするガス絶縁開閉装置の事故点標定装置。 A sealed container containing switching equipment and high-current conductors is divided into multiple gas compartments by insulating spacers, and a photodetector installed in each gas compartment detects abnormal light emission within the sealed container and detects an abnormality. A device for locating a gas compartment in which luminescence occurs, receives a photo-to-electrical converted output signal from a photodetector placed in a gas compartment housing the switchgear, and its duration is determined by the switching arc of the switchgear. A gas insulated switchgear characterized in that it is equipped with a judgment circuit that determines that abnormal light emission has occurred in the gas compartment and issues a signal instructing the output of a notification signal when the emission continues for a predetermined time exceeding the duration. Accident point locating device.
