Abstract
The utility model relates to a component structure of high voltage switchgear equipment, in particular to a bellows installation structure of an SF6 gas insulated vacuum circuit breaker. The structure comprises a gas tank internally provided with a vacuum arc extinguish chamber, the outer side of the gas tank is provided with a bellows; and the bottom part of the bellows is open and the top part thereof is closed, the bellows is connected with the outer wall of the gas tank by an annular installation plate at the bottom edge in a sealing way, and the inner side and the outer side of the top part of the bellows are respectively provided with a connecting rod used for being connected with the vacuum arc extinguish chamber and an operating mechanism. The bellows installation structure has simple structure and convenient installation and replacement and can reduce the volume of the gas tank.
Description
Technical field
The utility model relates to a kind of modular construction of high voltage switchgear, specifically is a kind of bellows mounting structure of SF6 gas-insulated vacuum circuit-breaker.
Background technology
In SF6 gas-insulated vacuum circuit-breaker, parts such as vacuum interrupter are installed in the SF6 gas tank of a sealing, and the first end of vacuum interrupter movable contact realizes that with the operating mechanism of outer gas tank outside dynamic seal (packing) is connected by bellows.In the existing structure, bellows is installed in the gas tank inboard usually, has following defective: 1, bellows has taken the installing space in the gas tank, thereby can increase the volume of gas tank, increases the aeration quantity of SF6 gas, is unfavorable for reducing cost; 2, because bellows is installed at box inside, be difficult to change, need open even destroy gas tank and bellows could be taken out, thereby increase the maintenance cost of equipment, also prolonged maintenance time in case bellows damages.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of simple in structure, install and change bellows mounting structure convenient, that can reduce the SF6 gas-insulated vacuum circuit-breaker of gas tank volume.
Structure of the present utility model includes the gas tank that inside is equipped with vacuum interrupter, and the gas tank outside is equipped with bellows; Described bellows bottom opening, top seal, bellows is tightly connected by the mounting panel of bottom margin annular and the outer wall of gas tank, and inside and outside both sides, bellows top are respectively arranged with and are used for the connecting rod that is connected with operating mechanism with vacuum interrupter.
Described mounting panel inboard is pressed on the gas tank outer wall by sealing ring, and the mounting panel outside is pressed with pressing plate, and pressing plate is fastened on the gas tank by screw.
The utility model has the advantages that: 1, bellows is positioned at the gas tank outside, makes gas tank inner structure compactness, can reduce the gas tank volume, save aeration quantity, has reduced cost; 2, be positioned at the bellows dismounting in the outside and need not to destroy the gas tank casing when changing, easy to maintenance, efficient is high; 3, because bellows is connected by pressing plate and gas tank are firm, and bellows can rotate freely when unclamping pressing plate, the adjusting of being carried out when vacuum circuit-breaker being installed to adapt to, and need not to consider the position of installing hole on the gas tank, greatly facilitate the debugging of circuit breaker.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the local structure for amplifying schematic diagram of the A of Fig. 1.
Embodiment
As shown in the figure, this structure comprises a gas tank 1, and the gas tank outside is equipped with bellows 2; Described bellows bottom opening, top seal, the bellows mounting panel 21 by the bottom margin annular is tightly connected with the outer wall of gas tank, and inside and outside both sides, bellows top are respectively arranged with and are used for the connecting rod 22 that is connected with operating mechanism with vacuum interrupter.The connected mode of mounting panel and gas tank is: mounting panel 21 inboards are pressed on gas tank 1 outer wall by sealing ring 3, and the mounting panel outside is pressed with pressing plate 4, and pressing plate is fastened on the gas tank by screw 5.
