Abstract
The utility model discloses a seal structure used for an outdoor SF6 inflatable vacuum circuit breaker switch, comprising a seal plate, a transition plate, an insulating china bottle and an upper outlet base, wherein a seal ring is arranged between the seal plate and the upper outlet base which are fixedly connected; a seal ring is arranged between the upper outlet base and the transition plate; a seal ring is arranged between the transition plate and the insulating china bottle which are fixedly connected; the structure also comprises a seal ring and a buffer device; the seal ring is arranged between the side surface of the upper outlet base and the transition plate; and the buffer device is arranged among the upper outlet base, the transition plate and the insulating china bottle. The seal ring is arranged on the upper outlet base for sealing, and the buffer device is additionally arranged to absorb the final motion gap caused by deciliter shaking of the arc extinguish chamber, and prevent SF6 gas leakage, thus having the characteristics of simple structure, small volume, flexible use, strong reliability, easy processing, low cost and the like.
Description
Technical field
The utility model relates to vacuum interrupter SF6 gas-insulated, specifically a kind ofly is used for outdoor SF6 gas-filled type vacuum circuit-breaker switch hermetically-sealed construction.
Background technology
For outdoor SF6 gas-filled type vacuum circuit-breaker, adopt the SF6 gas-insulated, not only insulation is reliable, and with low cost, satisfies no oiling requirement, is suitable for various environment and smog, special occasions such as high and cold.For the use of SF6 insulating gas, sealing becomes the product reliable premise, if sealing effectiveness is bad, causes SF6 gas along with vibrations are slowly revealed easily, influences the useful life of vacuum circuit-breaker.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of outdoor SF6 gas-filled type vacuum circuit-breaker switch hermetically-sealed construction that is used for, and improves because of the arc control device deciliter fine motion gap of bringing, and prevents gas leakage.
For achieving the above object, the technical solution of the utility model is as follows:
Include sealing plate, rebound, porcelain insulator and last outlet seat, be provided with sealing ring and fixedly connected between sealing plate and the last outlet seat, be provided with sealing ring between last outlet seat and the rebound, be provided with sealing ring between rebound and the porcelain insulator and fixedly connected, also include sealing ring and buffer unit, be provided with sealing ring between the side of last outlet seat and the rebound, be provided with buffer unit between last outlet seat and rebound, the porcelain insulator.
The utility model adopts in last outlet the sealing ring sealing is set, and other is provided with buffer unit and absorbs the fine motion gap that arc control device deciliter vibrations cause, prevents the SF6 gas leakage, have simple in structurely, volume is little, uses flexibly, good reliability, characteristics such as be easy to processing, cost is low.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is described in detail:
As shown in the figure, be provided with sealing ring and fixedly connected between sealing plate 1 and the last outlet seat 6, be provided with sealing ring between last outlet seat 6 and the rebound 2, be provided with sealing ring between rebound 2 and the porcelain insulator 5 and fixedly connected, be provided with sealing ring 3 between the side of last outlet seat 6 and the rebound 2, be provided with buffer unit 4 between last outlet seat 6 and rebound 2, the porcelain insulator 5.When arc control device divide fashionable, the side and the O RunddichtringO 3 between the rebound 2 that are arranged at outlet seat 6 can be sealed SF6 gas effectively, and be arranged at buffer unit 4 between outlet seat 6 and rebound 2, the porcelain insulator 5, can make spring, it also can be the device of other its cushioning effects, can absorb the fine motion gap that arc control device divide fashionable generation vibrations to cause, prevent gas leakage.
