This method is complicated to operate and has a general dustproof effect. However, GIL maintenance has extremely high requirements for on-site dust values, and traditional dustproof methods cannot meet the GIL maintenance quality standards. Therefore, it is urgent to design a device that is easy to set up, simple to operate, and has good dustproof properties to improve the quality of GIL maintenance. Summary of the invention

[0012] The utility model provides a dustproof shed for GIL pipeline operations, which seals the interior of a frame through door panels to prevent dust or powder from entering. The interior space of the frame can be used as a workpiece for GIL pipeline maintenance. When the space is insufficient, two door panels without dust covers can be opened. When no operation is performed, all door panels are closed to achieve dust prevention.

[0013] The utility model has the following beneficial effects:

[0014] 1. The GIL pipeline operation dustproof shed adopts a modular on-site assembly structure, which is easy and quick to assemble, easy to tighten and operate, and has reliable connection.
