In other embodiments, the two molecular sieves and the local sensor mounting holes can be uniformly distributed on the cover plate in a triangular shape, so that the molecular sieves can avoid shielding the local sensor.
GIS in this application is when the assembly, because molecular sieve, density relay 9, sensor 13 and blasting subassembly 11 are all integrated on apron 3 in the office, need not to set up the mounting hole alone and seal assembly to every spare part alone for these spare parts on sealed housing 1, reduced the processing degree of difficulty to sealed barrel 1, only need during the assembly with GIS apron subassembly 2 and sealed barrel 1 seal assembly can, assembly work load is little, assembly cost is low.
The GIS of the present invention, embodiment 2, differs from embodiment 1 in that only the molecular sieve, the density relay, and the partial discharge sensor are integrated on the cover plate, and the explosion assembly is mounted on the sealed housing; set up like this and reduced GIS apron subassembly's weight when guaranteeing certain integrated level in order to reduce the assembly degree of difficulty, make things convenient for single independent assembly, in other embodiments, also can only integrate at the apron with molecular sieve, density relay and blasting subassembly, install the sensor on sealed casing with the office.
The GIS embodiment 3 of the present invention differs from embodiment 1 in that the blasting assembly mounting holes are located away from the positions corresponding to the molecular sieves, so that the parts are uniformly distributed on the cover plate, the center of gravity of the GIS cover plate assembly is close to the geometric center of gravity, and the transportation is convenient.
The specific embodiment 4 of the GIS of the present invention is different from embodiment 1 in that two molecular sieves can be symmetrically arranged in front and back, and the uniformity of adsorption can still be ensured. In other embodiments, two molecular sieves may be disposed adjacent to each other on the cover plate.
The specific embodiment 5 of the GIS of the present invention is different from the embodiment 1 in that the cavity structure of the molecular sieve is independent of the cover plate, and specifically, a square box with a gas-permeable cover plate is adopted, and the square box is fixed on the cover plate by welding or screwing, so that the difficulty in forming the cover plate can be reduced.
The specific embodiment 6 of the GIS of the present invention is different from the embodiment 1 in that the cover plate is of a flat plate structure, and at this time, the cover plate is difficult to process, and a space for accommodating parts on the cover plate needs to be reserved at the open end of the sealed housing.
In other embodiments, the number of the molecular sieves can be set according to requirements, at least one molecular sieve is arranged, and when one molecular sieve is adopted, the communication channel and the blasting assembly mounting hole can be simultaneously communicated with the inner cavity of the molecular sieve, so that parts are more intensively arranged, the area occupied by a cover plate is reduced, and positions for mounting other parts and room for subsequent improvement can be reserved; other embodiments the openings of the cavity structures in the molecular sieve may be oriented in a direction perpendicular to the axis of the cover plate, or the openings of the cavity structures in the molecular sieve may be oriented at an acute angle to the axis of the cover plate.
