Abstract
The outdoor AC high-voltage isolation switch insulation column rotary support that the utility model provides, rotating shaft rotates and is arranged on bearing body axis, be provided with taper roll bearing and small-bore lower taper roll bearing on aspectant heavy caliber between the upper bearing (metal) chamber of bearing body and ring flange and between lower bearing chamber and rotating shaft axle journal, between the outer ring of upper taper roll bearing and upper bearing (metal) chamber, seal between lower bearing chamber and rotating shaft axle journal.The technical program provides more strong axial bearing capacity, and radial load bearing value, under comparatively severe environmental conditions, also can ensure flexibly, reliably and accurately complete separating brake, combined floodgate, and have good sealing and self-lubricating property.
Description
Technical field
The utility model relates to the alternating-current high-voltage isolation switch horizontally rotating three-phase ganged structure, in particular horizontally rotate the insulation column bearing of double-fracture three pillar type three-phase ganged outdoor high-voltage alternating current isolating switch.
Background technology
Though this explanation is with GW7-252 type outdoor high-voltage alternating current isolating switch product for typical case, this protection range not limit by illustrative examples.GW7-252 type outdoor high-voltage alternating current isolating switch is the non-loaded circuit switching of responsible three-phase alternating current and by the high voltage bus, the isolating switch of electrical isolation between circuit breaker and live high voltage circuit that overhaul.Its main technique requirements has: significantly separating brake cut-off point, enough insulation distances, stable mechanical strength, Dynamic stability and dielectric strength.Thrust ball bearing is adopted to support in the insulation column bearing of existing outdoor AC high-voltage isolating switch, it is the one of this class formation disclosed in Chinese patent CN2718762, the technical problem that this class formation exists is: only have axial force ability to bear, without radial load ability to bear, and axial force ability to take the burden is limited, be difficult to the dynamic stability ensureing integral product, in addition, sealing, lubricious setting and assembling all comparatively difficulty.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of outdoor AC high-voltage isolation switch insulation column rotary support ensureing rotating insulated pillar and integral frame dynamic stability.The outdoor AC high-voltage isolation switch insulation column rotary support technical scheme that the utility model provides, its main technical content is: a kind of outdoor AC high-voltage isolation switch insulation column rotary support, rotating shaft rotates and is arranged on bearing body axis, ring flange is fixed on rotating shaft upper end, taper roll bearing and small-bore lower taper roll bearing on aspectant heavy caliber is provided with between the upper bearing (metal) chamber of bearing body and ring flange and between lower bearing chamber and rotating shaft axle journal, seal between the outer ring of upper taper roll bearing and upper bearing (metal) chamber, seal between lower bearing chamber and rotating shaft axle journal.
In above-mentioned overall technical architecture, outside two taper roll bearings, be provided with packer accessory.
Outdoor AC high-voltage isolation switch insulation column rotary support technical scheme disclosed in the utility model, on heavy caliber, taper roll bearing and small-bore lower taper roll bearing is upper, lower support effect, provide and more have strong axial bearing capacity, and radial load bearing value, the rotating insulated pillar of this type of isolating switch can be born reliably divide, combined floodgate actuating effect, under comparatively severe environmental conditions, also separating brake can be ensured, close a floodgate flexibly, reliably and accurately complete, the technical program structure defines labyrinth sealing and self-lubricating environment through rotating shaft axial plane in addition, it is made to keep good sealing and self-lubricating property.
Accompanying drawing explanation
Accompanying drawing is total sectional structure chart of the present utility model.
Embodiment
Outdoor AC high-voltage isolation switch insulation column rotary support disclosed in the utility model, its form comprise bearing body 6 and with the rotating shaft 15 that is rotatably assorted on bearing body 6 axis, ring flange 1 is fixedly assemblied in rotating shaft 15 upper end, fixed insulation pillar.Bearing body 6 liang fixedly picks up the ears 16 to be fixedly installed on switch pedestal crossbeam by fixture.
Taper roll bearing 4 and small-bore lower taper roll bearing 8 on aspectant heavy caliber is provided with between the upper bearing (metal) chamber of bearing body 6 and ring flange 1 and between lower bearing chamber and rotating shaft 15 axle journal, between upper bearing (metal) chamber base ring mouth and the inner ring of upper taper roll bearing 4, sealing ring 5 is set, between lower bearing chamber and rotating shaft 15 axle journal, lower seal 7 is set.Packer accessory is provided with outside two taper roll bearings, described packer accessory is upper closed-loop 3 and lower closed-loop 10, the interior side ring surface of upper closed-loop 3 is fixed between ring flange 1 and upper taper roll bearing 4 inner ring, be closed in taper roll bearing 4 upper port, lower closed-loop 10 closes the lower port being arranged at lower taper roll bearing 8.Two taper roll bearings 4,8 constitute labyrinth sealing and self-lubricating environment, and permanent maintenance moves cooperation flexibly.
