Background technology
Gas switchgear is widely used at high pressure and ehv power transmission system break road device, the axial sealing of gas switch is one of key technology of switchgear, if the axial sealer of switchgear can not guarantee fully in the switchgear in fill insulating gas and do not reveal, will affect rotating shaft and under harsh operating mode, move.Therefore, the leakage that how the to prevent gas particularly preventing gas leakage work of axial motion place fails effectively to be solved always, and this technological innovation is under this requires, and the change design satisfies the axial seal effect of gas switchgear.
See also shown in Figure 1ly, it has shown the structural representation of the axial sealer of existing gas switchgear.As shown in Figure 1, the axial sealer of existing gas switchgear mainly comprises: guide ring 11, U-shaped shaft seal 12, power transmission shaft 13, O RunddichtringO 14, fixture 15, dust ring 16, upper shell 17, lower house 18.The axial sealer of existing gas switch is positioned by the direction of motion of 11 pairs of axles 13 of guide ring, utilize the arc control device internal gas pressure to produce the axial seal effect greater than U-shaped shaft seal 12 compressive deformations of forcing of atmospheric pressure, fixture 15 pushes mutually with upper shell 17, lower house 18, and then O RunddichtringO 14 also is squeezed, form airtight between fixture, after upper shell 17 and lower house 18 usefulness bolts are fixed and clamped, O RunddichtringO 14 between upper-lower casing also is squeezed, form airtight between upper-lower casing, thereby realize the airtight of total system.
The axial sealer complex structure of existing this gas switch, sealing effectiveness is not good, easily causes the leakage of gas in the switch.
The utility model content
It is a kind of easily assembled that the purpose of this utility model is to provide, the axial sealer of the gas switch of good sealing effect, the technical problem of the axial seal poor effect of the existing gas switchgear of solution.
For reaching aforementioned purpose, the axial sealer of a kind of gas switchgear of the utility model, it comprises guide ring, shaft seal, the dust ring of power transmission shaft, axle sleeve, sealing ring and power transmission shaft and shaft room.Wherein, the upper end of power transmission shaft is arranged in the arc control device that put in an end in the switchgear body, the lower end of power transmission shaft is arranged in the mechanism case that puts in the arc control device below, axle sleeve and switchgear body housing are bolted, described guide ring is arranged on the centre of axle sleeve, described shaft seal is arranged on the two ends of axle sleeve, and described dust ring is arranged between the shaft seal.
According to an embodiment of the present utility model, described shaft seal is V-packing, is arranged on the fixture.
According to an embodiment of the present utility model, described V-packing has two, and one group of V-packing is arranged on axle sleeve and puts in an end in the switchgear body near power transmission shaft; Another group V-packing is arranged on axle sleeve and puts in mechanism case one end near power transmission shaft, and gas switchgear is carried out the internal layer sealing.
According to an embodiment of the present utility model, described dust ring has two, is separately positioned between the V-packing, and preventing has dust to enter in the air chamber when power transmission shaft from rotating.
According to an embodiment of the present utility model, described sealing ring is the O RunddichtringO, is arranged between axle sleeve and the switchgear body housing, and gas switchgear is carried out outer static sealing
The beneficial effects of the utility model: the centre that guide ring is arranged on axle sleeve, guarantee that power transmission shaft reliably turns round, and position, two groups of V-packings are arranged on the two ends of axle sleeve, can guarantee gas switchgear in fill the insulation gases at high pressure can not reveal, adopt simultaneously the O RunddichtringO that gas switchgear is carried out outer static sealing, two groups of dust rings are arranged between the V-packing, prevent having dust to enter in the air chamber when power transmission shaft from rotating, the utility model compared with prior art, simple in structure, it is convenient to install, and sealing effectiveness is better.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
See also shown in Figure 2ly, the axial sealer of gas switchgear of the present utility model comprises guide ring 24, shaft seal 25,26, the dust ring 28,29 of 22 on power transmission shaft 21 axle sleeves 22, sealing ring 23 and power transmission shaft 21 and axle sleeve.
Wherein, the upper end of power transmission shaft 21 is arranged in the arc control device that put in an end in the switchgear body, and the lower end of power transmission shaft 21 is arranged in the mechanism case that puts in the arc control device below.
Wherein, axle sleeve 22 and switchgear body housing 210 are bolted, and O RunddichtringO 23 is arranged on 210 of axle sleeve 22 and switchgear body housings, and gas switchgear is carried out outer static sealing,
Wherein, guide ring 24 is arranged on the centre of axle sleeve 22, and the direction of motion of power transmission shaft 21 is positioned.
