Abstract
The utility model relates to an outdoor high-voltage vacuum circuit breaker and belongs to the structure that three separate phases share the same pedestal, wherein, three-phase insulating tubes are fixed on a box body; each insulating tube consists of an upper insulating tube and a lower insulating tube, and a flange is fixed between the upper insulating tube and the lower insulating tube; the insulating tube is internally provided with a vacuum arc extinguish chamber, the upper part is connected with an upper patch board and the lower is connected with an insulating pull rod, and the vacuum arc extinguish chamber is connected with a lower patch board and a current transformator through the flange. The utility model is characterized in that the periphery of the vacuum arc extinguish chamber which is made of porcelain is made into the shape of an umbrella skirt, and the distance between the vacuum arc extinguish chamber and the internal wall of the insulating tube is enlarged, thus increasing the creepage distance of the vacuum arc extinguish chamber. Therefore, the utility model can meet the insulating requirements without filling any materials in the gap between the vacuum arc extinguish chamber and the insulating tube and has the advantages of simple structure and reliable performance.
Description
Technical field
The utility model relates to the high pressure or the high-current switch technical field of band arc extinguishing or flash guard, especially relates to a kind of vacuum circuit-breaking switch.
Background technology
In the existing outdoor high-voltage vacuum breaker technology of China, adopt the three-phase combined type structure mostly at present, its difficult sealing easily produces condensation, has reduced dielectric strength; Also have and adopt the three-phase separate structure, but exist the not good enough problem of insulation property, and need between vacuum interrupter and insulating cylinder, to increase to fill insulating cement, easily produce the slit in this structure between vacuum interrupter and the insulating cement, cause insulation breakdown, reduced the reliability of circuit breaker.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of prior art, a kind of outdoor high-voltage vacuum breaker that need not filling insulating cement between vacuum interrupter and insulating cylinder to be provided.
The technical solution of the utility model is such: a kind of outdoor high-voltage vacuum breaker, it is the discrete understructure altogether of three-phase, the three phase isolated tube is fixed on the casing, every phase insulating cylinder is made up of last insulating cylinder and following insulating cylinder, center fixed has flange, vacuum interrupter is housed in the insulating cylinder, the top of vacuum interrupter is connected with upper wiring board, the lower end is connected with conductive clip, and link to each other with above-mentioned flange by being flexible coupling, also be fixed with down the terminal block summation current transformer on the flange, the current transformer lower end is connected with casing by insulating case; The lower end of vacuum interrupter is passed the conductive clip that connects thereon and is linked to each other with the top of insulated tension pole, stage clip is housed on the insulated tension pole, its lower end links to each other with drive stay by connecting plate, about connecting plate has two, respectively insulated tension pole and drive stay and support is fixed by pin; Tripping spring is housed on the drive stay, and is connected with auxiliary switch that is installed in the casing top and spring mechanism respectively, spring mechanism is connected with the overcurrent release that is installed in the casing side, deciliter handle and energy storage handle again; The casing side also is equipped with deciliter pointer that links to each other with drive stay and the aviation plug and the earth stud that link to each other with the secondary control circuit; Casing is sealed by base plate; Vacuum interrupter in the above-mentioned insulating cylinder is by ceramic making, and its periphery makes the full skirt shape, and distance between increase and the insulating cylinder inwall.
Owing to adopted technique scheme, vacuum interrupter creepage distance of the present utility model increases, and the space between itself and the insulating cylinder does not need any object of filling can satisfy insulating requirements, and simple in structure, dependable performance.
