Abstract
A kind of epoxy resins insulation support frame, comprise the support frame body of epoxy resin material, vacuum switch tube chamber and driving mechanism chamber is respectively equipped with in support frame body, in vacuum switch tube chamber, vacuum switch tube is installed, vacuum switch tube one end is fixed on support frame body, the other end is deep in driving mechanism chamber through vacuum switch tube chamber, described driving mechanism comprises being flexible coupling of being connected successively with vacuum switch tube end, wedging ring, connecting rod, transmission crank arm, mechanism's connecting axle, the axle that is in transmission connection passes driving mechanism chamber and is connected with operating mechanism.This epoxy resins insulation support frame to realize carrying out full sealing to vacuum interrupter body, vacuum interrupter moving contact and insulated tension pole coupling part, insulated tension pole body, thus achieve dynamic electrified body hermetically sealed, strengthen electrified body insulation against ground, do not affect electrified body motion again.
Description
Technical field
The utility model relates to a kind of technical field of power equipment, particularly relates to a kind of epoxy resins insulation support frame.
Background technology
At present in known medium-voltage equipment, the pole of vacuum switch tube has just carried out sealing to vacuum switch tube body, enhance its external insulation, but sealing is not carried out in its moving contact and insulated tension pole coupling part, so all there is cavity in existing pole inside around insulated tension pole.And at present mostly adopt the gas isolated insulation mode of air insulation, SF6 for the process of this cavity, but air-insulated insulation volume is large, insulation property are poor, affect by outdoor environment and very easily cause apparatus insulated puncturing; And SF6 gas insulation decline also can not easily cause equipment explosion after High aititude or extremely tremble with fear area application, SF6 Leakage Gas, and sulphur hexafluoride belongs to greenhouse gas, not environmentally, not easily reclaims.Therefore existing insulating sleeve cannot carry out full sealing to vacuum interrupter body, vacuum interrupter moving contact and insulated tension pole coupling part, insulated tension pole body.
Utility model content
For solving the problem, the utility model provides a kind of epoxy resins insulation support frame.
The technical solution of the utility model is: a kind of epoxy resins insulation support frame, comprise the support frame body of epoxy resin material, vacuum switch tube chamber and driving mechanism chamber is respectively equipped with in support frame body, it is characterized in that: in vacuum switch tube chamber, vacuum switch tube is installed, vacuum switch tube one end is fixed on support frame body, the other end is deep in driving mechanism chamber through vacuum switch tube chamber, described driving mechanism comprise be connected successively with vacuum switch tube end be flexible coupling, wedging ring, connecting rod, transmission crank arm, mechanism's connecting axle, the axle that is in transmission connection passes driving mechanism chamber and is connected with operating mechanism.
Hard silica gel is cast with in described vacuum switch tube chamber; Soft silica gel is cast with in described driving mechanism chamber.
The utility model discloses a kind of epoxy resins insulation support frame to realize carrying out full sealing to vacuum interrupter body, vacuum interrupter moving contact and insulated tension pole coupling part, insulated tension pole body, thus achieve dynamic electrified body hermetically sealed, strengthen electrified body insulation against ground, do not affect electrified body motion again.
Accompanying drawing explanation
Fig. 1 is epoxy resins insulation support frame front view.
In figure 1, support frame body, 2, cover plate, 3, vacuum switch tube, 4, be flexible coupling, 5. compressing spring, 6. wedging ring, 7. connecting rod, 8. scraper bowl connecting lever, 9. mechanism's connecting axle, 10. soft silica gel, 11. hard silica gel.
Embodiment
See a kind of epoxy resins insulation support frame of figure, comprise the support frame body of epoxy resin material, vacuum switch tube chamber and driving mechanism chamber is respectively equipped with in support frame body, in vacuum switch tube chamber, vacuum switch tube is installed, vacuum switch tube one end is fixed on support frame body, the other end is deep in driving mechanism chamber through vacuum switch tube chamber, described driving mechanism comprise be connected successively with vacuum switch tube end be flexible coupling, wedging ring, connecting rod, transmission crank arm, mechanism's connecting axle, the axle that is in transmission connection passes driving mechanism chamber and is connected with operating mechanism.Hard silica gel is cast with in described vacuum switch tube chamber; Soft silica gel is cast with in described driving mechanism chamber.
The utility model is a kind of epoxy resins insulation support frame, comprises epoxy resins insulation support frame 1, and one end is fixed on the pole vacuum switch tube 3 of support frame 1 one end; The pole other end of vacuum switch tube 3 is connected with by wedging ring 6, M10 connecting rod 7, compressing spring 5,4 assemblies formed that are flexible coupling, be connected with transmission crank arm 8 by wedging ring 6, M10 connecting rod 7, compressing spring 5,4 assemblies formed that are flexible coupling, transmission crank arm 8 is connected with mechanism connecting axle 9, cover plate 2 and support frame 1 assemble and support frame 1 are divided into two spaces do not communicated, build hard silica gel 11 to support frame 1 and the cavity residing for pole vacuum switch tube 3 under vacuum conditions, build soft silica gel 10 to the space residing for transmission crank arm under vacuum conditions.
Adopting vacuum casting process when pouring into a mould soft silica gel and hard silica gel, and removing moisture, after ensureing that it pours into a mould, excellent interior insulation property integrally.
The above is only preferred embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in patent claim of the present invention.
