Abstract
The utility model relates to a gas -insulated cabinet seal structure. Including the three -phase moving contact, every moving contact sets up the front end at a drive part, and a drive part's rear end is connected with insulating pull rod, be provided with three through -hole on the wallboard of the insulating case body, stretch out from the through -hole that corresponds the rear end of every insulating pull rod to on being connected to circuit breaker operating device through drive mechanism, be provided with the bellows of cover on insulating pull rod between insulating pull rod and the through -hole, the rear end of bellows has annular connecting seat, is provided with flange between the outer wall of connecting seat and wallboard, is provided with the flange joint hole on connecting seat and the wallboard, and flange, connecting seat and wallboard pass through flange bolt zonulae occludens and be in the same place, be provided with annular recess respectively on the lateral wall around the flange, install the sealing washer in the recess. The sealing device that the three -phase moving contact corresponds is mutually independent, has reduced the installation accuracy, and the divide -shut brake precision is convenient for improve in convenient debugging.
Description
Technical field
The utility model relates to a kind of medium voltage switchgear equipment, specifically a kind of gas-insulated cabinet hermetically-sealed construction.
Background technology
Gas-insulated cabinet of the prior art comprises three-phase moving contact, and each moving contact is arranged on the front end of the running part being arranged in insulation box, and the rear end of a described running part is connected with insulated tension pole; The wallboard of insulation box is provided with three through holes, the rear end of each insulated tension pole is stretched out from the through hole of correspondence, and is connected on circuit breaker operation mechanism.Existing hermetically-sealed construction comprises plate sealing together, is provided with the hole corresponding with the through hole on wallboard, and is sealed by seal on described sealing plate.
Its shortcoming is: 1, due to the hole on sealing plate will be made to align with the hole on wallboard, installation accuracy is high, and wastes time and energy.2, debugging is not easy to, after three-phase moving contact installs, owing to needing the precision improving divide-shut brake, need the position of constantly debugging moving contact, when adjusting one of them moving contact, other two are often affected, add the difficulty of debugging, limit the raising of divide-shut brake precision.3. seal structure complex, cost is high.
In prior art, syndeton circuit breaker actuating mechanism be connected on wallboard is complicated, and cost is high.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of structure simple, install, debug gas-insulated cabinet hermetically-sealed construction easily.
Gas-insulated cabinet hermetically-sealed construction of the present utility model, comprises three-phase moving contact, and each moving contact is arranged on the front end of the running part being arranged in insulation box, and the rear end of a described running part is connected with insulated tension pole; The wallboard of insulation box is provided with three through holes, the rear end of each insulated tension pole is stretched out from the through hole of correspondence, and is connected on circuit breaker operation mechanism by transmission mechanism;
The bellows be enclosed within insulated tension pole is provided with between described insulated tension pole and through hole, the rear end of described bellows has the Connection Block of annular, adpting flange is provided with between Connection Block and the outer wall of wallboard, described Connection Block and wallboard are provided with flange connecting hole, and described adpting flange, Connection Block and wallboard pass through together with flange bolt compact siro spinning technology; The front-rear side walls of described adpting flange is respectively arranged with the groove of annular, in described groove, sealing ring is installed.
Circuit breaker frame is provided with flange connecting hole, is connected on the rear wall of Connection Block by above-mentioned flange bolt.
The sealing device that three-phase moving contact is corresponding is separate, reduces installation accuracy, and convenient debugging, when debugging the position of one of them moving contact, can not affect the position of other moving contact, is convenient to the precision improving divide-shut brake.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
