The invention discloses a leakage-proof adsorbent frame and a GIS provided with the adsorbent frame. The leakage-proof adsorbent frame comprises a screen plate. The outer side or the inner side of the screen plate is provided with a leakage-proof net. The shape of the leakage-proof net is matched with the shape of the screen plate. The leakage-proof net is provided with leakage-proof holes, wherein the hole diameters of the leakage-proof holes are smaller than the diameters of screen holes in the screen plate. According to the technical scheme of the invention, the structure of the leakage-proof net is additionally arranged on the structural basis of an existing screen plate. The leakage-proof net is provided with leakage-proof holes and the hole diameters of the leakage-proof holes are relatively small. Therefore, the adsorbent leakage condition in the screen plate is greatly improved. Meanwhile, the permeability of the adsorbent frame is almost not influenced at all.
