Novel gas insulated metal-enclosed circuit (GIL) gas chamber structure

The utility model relates to a novel gas insulated metal enclosed line (GIL) gas chamber structure, which comprises a GIL pipeline and a GIL gas chamber arranged in the GIL pipeline, the GIL gas chamber comprises a plurality of large gas chambers which are connected, the plurality of large gas chambers are mutually independent gas chambers, the large gas chambers comprise a small gas chamber, a middle gas chamber and a small gas chamber which are connected in sequence, and the middle gas chamber is connected with the small gas chamber. The two small air chambers and the middle air chamber are independent air chambers, and inflation and deflation ports are formed in the two small air chambers and the middle air chamber. According to the utility model, the structure of the large air chamber is optimally designed, when one air chamber needs to be subjected to air extraction or vacuumizing maintenance, only one middle air chamber and two small air chambers in a small-middle-small or middle-small-small structure n
