Summary:The utility model relates to a GIS isolation grounding switch far and near control converting loop. The converting loop is provided with a converting switch, an AC/DC device, a storage battery and a DC relay, wherein an alternated current connection pin of the AC/DC device is connected to a power supply end of an alternated current power supply; a coil of the DC relay is serially connected to the converting switch to form a converting branch; and the converting branch is connected to the storage battery in parallel and is connected to the anode and cathode of the alternated current connection pin of the AC/DC device. The converting loop transforms the alternated current supplied by the alternated current power supply into the direct current through the AC/DC device, stores the direct current for the storage battery and uses the current as the power supply of the DC relay. Even if the alternated current power supply is cut off caused by the failure of the transformer substation, the GIS isolation grounding swi
