Abstract
The utility model provides a gas tank structure of a gas insulation switch device. The gas tank structure of the gas insulation switch device comprises a tank body and a sealing cover plate arranged on the tank body, and is characterized in that two annular reinforcing ribs are arranged on the top of the tank body, the gap between the two annular reinforcing ribs forms a sealing groove, and a sealing ring which is arranged on the sealing cover plate is matched with the sealing groove. The tank body of the gas tank structure of the gas insulation switch device is formed in a welding mode by a high-compactness stainless steel plate, through the two annular reinforcing ribs arranged on the top of the tank body, structural transformation is greatly reduced, intensity is increased, and electric field uniform distribution and gas circulation are better achieved. Meanwhile, the sealing groove is matched with the sealing cover plate, and accordingly tightness of the tank body is improved and unreliable sealing because of the structural transformation is reduced at the same time. Compared with the prior art, the gas tank structure of the gas insulation switch device is small in deformation and reliable in tightness.
Description
Technical field
The utility model belongs to the switch cubicle fitting field, is specifically related to a kind of gas tank structure of gas-insulated switchgear.
Background technology
The gas tank box house of gas-insulated switchgear has certain pressed gas, so it is very high to sealing requirements.Gas tank in the past generally all adopts fully closed structure, does not possess the function that gas tank is opened, but the maintenance of this totally enclosed type gas tank and maintenance are very difficult.In recent years, the gas tank of openable occurred, but openable gas tank sealing of the prior art is not good enough.
The utility model content
The utility model provides a kind of gas tank structure of reliable sealing gas-insulated switchgear to the deficiency of above-mentioned prior art.
The utility model is realized through following technical scheme:
A kind of gas tank structure of gas-insulated switchgear comprises casing and is arranged at the seal cover board on the casing that it is characterized in that the top of said casing is provided with two ring stiffeners, the gap between two ring stiffeners constitutes a seal groove; Seal cover board is provided with sealing ring, and said sealing ring and seal groove are complementary.
The further setting of the utility model is that the bottom of said casing is provided with pressure release passage.
The further setting of the utility model is that the top of said casing also is provided with plug-in unit connection hole.
The further setting of the utility model is, is welded with a plurality of bolts on the sidewall of said casing.
The casing of the gas tank structure of the described gas-insulated switchgear of the utility model adopts the high compactness corrosion resistant plate to be welded; It is provided with two ring stiffeners through the top at casing; Significantly reduced the distortion of structure, increased intensity, helped that electric field is uniformly distributed with and gas communication; Seal groove cooperates with seal cover board simultaneously, when strengthening box sealing property, has also reduced the unreliable problem of the sealing that brings owing to malformation.Compared with prior art, the deflection of the gas tank structure of the described gas-insulated switchgear of the utility model is less, and sealing is more reliable simultaneously.
