Abstract
The utility model relates to the technical field of high-voltage 126-kV switch electric equipment and particularly relates to an arc extinguish chamber tank for a 126-kV common-box GIS (Gas Insulated Switchgear), comprising a cylindrical shell, wherein three pulling openings are formed at the side part of the shell; sealing cover plates are arranged at the outer sides of the three pulling openings; a welded sealing cover plate is arranged at the lower end of the shell; a detachably-connected sealing cover plate is arranged at the upper end of the shell; a mechanism box is arranged on the upper part of the shell; the sealing cover plate at the upper end of the shell is provided with a through hole through which a pull rod can pass; and the pull rod of an arc extinguish chamber stretches out of the mechanism box to be connected with the sealing cover plate. The arc extinguish chamber tank for the 126-kV common-box GIS has the characteristics that structure is simple, production and installation are convenient, maintenance is reduced and cost is lowered.
Description
Technical field
The utility model relates to a kind of high pressure 126kV switch electric equipment technical field, and specifically a kind of 126kV case GIS altogether uses the arc control device tank body.
Background technology
The circuit of 126kV electric pressure directly arrives city transformer station in the big-and-middle-sized industrial city; Annual according to country's year power consumption calculating; Country needs 126kV, and case GIS at interval approximately need be up to ten thousand individual altogether, and each need join a circuit breaker at interval, and every circuit breaker then needs an arc control device tank body.In the design in the past, owing to consider that symmetrical structure, the tank body of design are four and pull out mouth.Pull out increasing of mouthful number, cause the possibility of occurrence of waste in the course of processing to increase; And because the increase of pulling out mouthful number needs more sealing, because in the installation process, sealing part increases, the probability that causes leaking gas also can be bigger than normal.And, increased the production and the maintenance cycle of this equipment owing to pull out the volume that mouth has increased material usage and increased tank body, cause the cost of tank body sharply to rise.
Summary of the invention:
In order to overcome above-mentioned defective, it is a kind of simple in structure that the utility model provides, and is convenient to produce and install, and reduces and safeguard, the 126kV that reduces cost case GIS altogether uses the arc control device tank body.
The technical scheme of the utility model is: a kind of 126kV case GIS altogether uses the arc control device tank body; Comprise cylindrical shell; It is characterized in that: described housing sidepiece is provided with three and dials mouth, and three outsides of dialling mouth are provided with seal cover board, are provided with the seal cover board that is welded to connect in the lower end of housing; Be provided with the seal cover board that removably connects in the upper end of housing, be provided with mechanism case on the top of housing, the seal cover board of housing upper end is provided with the through hole that pull bar can pass, and the pull bar of arc control device stretches out the sealing cover plate and is connected with mechanism case.
The utility model design is provided with seal cover board in the housing upper end, the sealing cover plate top case that sets up an organization, and dialling of housing sidepiece mouthful is set to three; Reduced the unnecessary mouth that pulls out, obviously reduced the probability of gas leakage, three of both sides are pulled out mouth and are connected through cover plate for sealing or with the bus bar canister of transition; Effectively reduce sealing part, reduced the probability of gas leakage, reduced the expense of tank body processing simultaneously; Reduce cost, also improved the high-voltage switch gear reliability of operation.

Embodiment:
The technical scheme that the utility model adopts is: a kind of 126kV case GIS altogether uses the arc control device tank body, comprises cylindrical shell 1, and described housing 1 sidepiece is provided with three and dials mouth, and three groups mouthfuls the outside is provided with seal cover board.Be provided with the seal cover board that is welded to connect in the lower end of housing 1.Be provided with the seal cover board that removably connects in the upper end of housing 1; Be provided with mechanism case 2 on the top of housing 1; The seal cover board of housing 1 upper end is provided with the through hole that pull bar 3 can pass; Between pull bar 3 and sealing cover plate, be provided with sealing gasket usually, the pull bar 3 of arc control device stretches out the sealing cover plate and is connected with mechanism case 2.
The utility model is provided with seal cover board in housing 1 upper end, the sealing cover plate top case 2 that sets up an organization, and dialling of housing 1 sidepiece mouthful is set to three; Reduced the unnecessary mouth that pulls out, obviously reduced the probability of gas leakage, three of both sides are pulled out mouth and are connected through cover plate for sealing or with the bus bar canister of transition; Effectively reduce sealing part, reduced the probability of gas leakage, reduced the expense of tank body processing simultaneously; Reduce cost, also improved the high-voltage switch gear reliability of operation.
The utlity model has simple in structurely, be convenient to produce and install, reduce and safeguard, the characteristics that reduce cost.
