Abstract
The utility model discloses an insulating cylinder of high-voltage vacuum breaker, wherein the inner and the external of the top of a cylinder (1) are square structures, the inner and the external of the lower portion are circumferential structures, the inner and the external of an insulating cylinder are provided with skirt rims, the inner skirt rim is a whole circumference, wire outlet seats are arranged on the upper portion and the middle portion of the cylinder (1), a supporting shoe (2) is arranged on one side of the cylinder (1), an annular reinforced rib (3) is arranged along the circumference of the cylinder (1), and the annular reinforced rib (3) is connected with the supporting shoe (2). The insulating cylinder of high-voltage vacuum breaker improves the rigidity and the impact resistibility of the cylinder, satisfies the requirements of the impact damages of the cylinder due to the great electromotive power during the short circuit of the breaker of a high-voltage generator of 10 kV, and guarantees the safety operation of electric devices.
Description
Technical field
The utility model relates to a kind of high-pressure vacuum breaker insulating cylinder, and is relevant with vacuum circuit-breaker insulating cylinder structure with a kind of high-voltage generator outlet especially.
Background technology
Insulating cylinder is the important component part of high-pressure vacuum breaker, circuit breaker primary conductive loop is risen support and insulating effect.Traditional high-pressure vacuum breaker insulating cylinder is up and down circular, and the cylindrical shell top is inside and outside to be tetragonal, and the bottom is inside and outside to be circle configurations, be equipped with the shirt rim structure inside and outside the insulating cylinder, its inner skirt is whole circle circumference, and cylindrical shell top and middle part set out the line seat, and cylindrical shell one side is provided with the wedge-like back-up block.This structure, the electric power that can only bear the certain short circuit current of circuit breaker can not satisfy the requirement of big short circuit current, and particularly 10kV high-voltage generator outlet breaker is to the requirement of insulating cylinder.
The utility model content
The purpose of this utility model design exactly a kind of can satisfy the circuit breaker full capacity and cut-off greatly the time electric power insulating cylinder is impacted requirement, particularly the outlet of 10kV high-voltage generator is used the vacuum circuit-breaker insulating cylinder.
The utility model is that above-mentioned conventional high-tension vacuum circuit-breaker insulating cylinder is improved, the cylindrical shell top is inside and outside to be tetragonal, the bottom is inside and outside to be circle configurations, be equipped with the shirt rim structure inside and outside the insulating cylinder, its inner skirt is whole circle circumference, and cylindrical shell top and middle part set out the line seat, and cylindrical shell one side is provided with back-up block, the utility model is being set up ring-like reinforcement along the cylindrical shell circumference, and ring-like reinforcement links to each other with back-up block.
The high-pressure vacuum breaker insulating cylinder that the utility model provides, after fixedly mounting with circuit breaker, ring stiffener has improved the rigidity and the impact resistance of cylindrical shell, make the cylindrical shell shrinkage stress even, avoided the ovalizing deflection of the products solidifying process that causes because of shrinkage stress is irregular, improved the rate of finished products of product greatly, the requirement that electric power is impacted insulating cylinder when having satisfied the short circuit of 10kV high-voltage generator outlet breaker.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of an embodiment of the utility model high-pressure vacuum breaker insulating cylinder;
Fig. 2 is a left TV structure schematic diagram embodiment illustrated in fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, cylindrical shell 2, back-up block 3, ring stiffener
As shown in the figure, the utility model high-pressure vacuum breaker insulating cylinder cylindrical shell 1 top is inside and outside to be tetragonal, the bottom is inside and outside to be circle configurations, be equipped with the shirt rim structure inside and outside the insulating cylinder, its inner skirt is whole circle circumference, and cylindrical shell 1 top and middle part set out the line seat, and cylindrical shell 1 one sides are provided with back-up block 2, be provided with ring-like reinforcement 3 along cylindrical shell 1 circumference, ring-like reinforcement 3 links to each other with back-up block 2.
During use, at cylindrical shell 1 top and middle part the outlet arm is housed respectively, outlet arm and fin are by screw and the quiet end fixed connection of arc control device on the top, then fin is screwed in insulating cylinder inside, the following outlet arm that install at the middle part by lower carriage, be flexible coupling, conductive clip and the connection of vacuum interrupter moved end conducting rod, connect at back-up block place and circuit breaker frame by screw, ring stiffener plays the effect of hoop, improved insulating cylinder integral rigidity and shock-resistant ability, made electric equipment operation safety.
