Abstract
The utility model relates to a solid seal polar pole used for a high-current vacuum circuit breaker. The solid seal polar pole comprises a hollow epoxy resin insulator, wherein an upper outgoing-line seat and a lower outgoing-line seat are respectively arranged at the upper and the lower parts of the epoxy resin insulator; sheds are arranged at the lower part of an outer wall of the epoxy resin insulator, a vacuum arc-extinguishing chamber is arranged in a cavity of the epoxy resin insulator, and a movable end of the vacuum arc-extinguishing chamber is connected with the lower outgoing-line seat; and the solid seal polar pole is characterized in that the connection between the movable end of the vacuum arc-extinguishing chamber and the lower outgoing-line seat adopts a flexible connection structure. According to the utility model, a copper foil flexible connection structure is adopted to connect the movable end of the vacuum arc-extinguishing chamber and the lower outgoing-line seat, so that the reliable connection between the movable end and the lower outgoing-line seat is realized under the premise that the movable end of the vacuum arc-extinguishing chamber is not limited. As a plurality of symmetrical axial heat-dissipating reinforced ribs are arranged at the front and the back parts of the outer wall of the epoxy resin insulator, the mechanical strength of the solid-sealed polar pole body is improved, and good heat-dissipating effect is achieved.
Description
Technical field
The utility model belongs to a kind of high current vacuum circuit breaker pole.
Background technology
Pole with the use of electric power system vacuum circuit-breaker coupling, its structure comprises the epoxyresin insulator of a hollow, at the outlet seat on the position is respectively equipped with up and down and the following outlet seat of epoxyresin insulator, the bottom of epoxyresin insulator outer wall is provided with full skirt.Be provided with vacuum interrupter in the inner chamber of epoxyresin insulator, the moved end of vacuum interrupter is connected with following outlet seat, quiet end is connected with last outlet seat.
At present, the vacuum interrupter moved end of great-current fixed sealed pole and the syndeton of following outlet seat, need movable characteristic owing to consider the moved end, therefore, generally all adopt the slidingtype syndeton, promptly, guarantee the normal operation in pole loop by movable being overlapped on down on the outlet seat of spring touch finger.There are the following problems in actual use for this syndeton: spring touch finger is in long use, phenomenons such as mechanical wear, fatigue strength reduction can appear, thereby influence effective contact performance of spring touch finger and following outlet seat, will cause the normal operation of whole pole and even vacuum circuit-breaker equipment when serious.
Summary of the invention
For solving the problems referred to above that prior art exists, the utility model aims to provide a kind of high current vacuum circuit breaker pole, this pole can realize effectively that the vacuum interrupter moved end is connected with the reliable of following outlet seat under the prerequisite that does not limit the activity of vacuum interrupter moved end.
Realize that the above-mentioned purpose technical scheme is as follows, this high current vacuum circuit breaker pole comprises the epoxyresin insulator of a hollow, at the outlet seat and the following outlet seat on the position is respectively equipped with up and down of epoxyresin insulator; The bottom of described epoxyresin insulator outer wall is provided with full skirt, in the inner chamber of this epoxyresin insulator, be provided with vacuum interrupter, the moved end of this vacuum interrupter is connected with following outlet seat, it is characterized in that: the moved end of described vacuum interrupter is a flexible connection structure with following outlet seat.
During concrete enforcement,, be provided with the axial heat radiation reinforcement of many symmetries at the front portion and the back of described epoxyresin insulator outer wall.
Beneficial effect: compared with prior art, the utility model adopts the Copper Foil flexible connection structure to connect the moved end and the following outlet seat of vacuum interrupter, has realized that under the prerequisite that does not limit the activity of vacuum interrupter moved end the moved end is connected with the reliable of following outlet seat.Moreover, as required, be flexible coupling and adopt the high Copper Foil of conductance to be overrided to form, both can guarantee current capability, can also avoid because of the excessive thermal effect that produces of electric current impacts accessory, and under the situation of volume-diminished, ampacity does not diminish, and meets pole miniaturization requirement.In addition, at the front portion and the back of epoxyresin insulator outer wall, the axial heat radiation reinforcement of many symmetries is set after, both improved the mechanical strength of pole body, played good heat-radiation effect again.
