Abstract
The utility model relates to a device, through which a medium-voltage circuit breaker, a high-voltage circuit breaker, other high-voltage or ultra-high-voltage transmission and transformation equipment can be sealed in a translation manner. The device comprises a translation-sealing shaft (1), a sealing plate (2), two sealing washers (3), an O-shaped sealing ring I(4), an O-shaped sealing ring II (5), and an oil-less bearing (6); the translation-sealing shaft (1) is mounted in a shaft hole of the sealing plate (2); the O-shaped sealing ring II (5) is arranged between the sealing plate (2) and a bracket; the oil-less bearing (6) is mounted between the sealing plate (2) and the translation-sealing shaft (1); the sealing washers (3) and the O-shaped sealing ring I (4) are arranged at the middle part between the sealing plate (2) and the translation-sealing shaft (1); and the O-shaped sealing ring I (4) is arranged between the two sealing washers(3). The utility model is characterized by simple structure, convenient manufacture of spare parts, simple installation, reliable sealing, cost reduction, transmission efficiency improvement and the like.
Description
One, technical field
The utility model is in a kind of power transmission and transforming equipment, and the translation seal device of middle and high voltage breaker also can be used for the translation seal of other high pressure and ehv power transmission equipment.
Two, background technology
At present, the hermetic seal overwhelming majority of high-voltage sf6 circuit breaker moving contact operation rod member adopts rotary seal, rotate by being contained in rotating shaft on the transmission case that to take action bars to directly moving, sealing means is a rotary seal between rotating shaft and transmission case, and sealing apparatus structure complexity, transmission efficiency is not high, cost is high.
Three, summary of the invention
The purpose of this utility model provides the SF6 primary cut-out translation seal device that a kind of movable sealing structure is simple, transmission efficiency is higher, replace former rotary seal, make the overall structure of circuit breaker simple more, reliable, greatly reduce SF6 circuit breaker cost simultaneously.
For achieving the above object, the technical scheme that the utility model is taked is: include translation seal axle, sealing plate, seal washer, O RunddichtringO I, O RunddichtringO II, oilless bearing etc.The sealing plate middle part is provided with axis hole.Sealing plate is fixed on the support of circuit breaker, the translation seal axle pack into axis hole, and can move freely; Between sealing plate and support, be provided with O RunddichtringO II, with the end between the translation seal axle oilless bearing is housed at sealing plate, be provided with seal washer, O RunddichtringO I at sealing plate with the middle part between the translation seal axle, O RunddichtringO I is contained in the middle of two seal washers.
Operation principle: when the translation seal axle moves up and down, play the guiding role by seal washer and oilless bearing, seal group decrement between translation seal axle and the sealing plate is kept evenly, and seal washer can prevent that also O RunddichtringO I is extruded, and causes gas leak phenomenon simultaneously.After increasing oilless bearing, can make guiding more reliable, guarantee that the seal group decrement keeps evenly, thereby guaranteed sealing effectiveness.
Therefore the utlity model has simple in structurely, parts are easy to process, install simply, and sealing is reliable, and cost reduces, characteristics such as transmission efficiency raising.
Four, description of drawings
Accompanying drawing is a schematic diagram of the present utility model.
Five, embodiment
Accompanying drawing is embodiment of the present utility model, includes translation seal axle 1, sealing plate 2, seal washer 3, O RunddichtringO I 4, O RunddichtringO II 5, oilless bearing 6 etc.Sealing plate 2 middle parts are provided with axis hole.Sealing plate 2 is fixed on the support of circuit breaker, translation seal axle 1 pack into axis hole, and can move freely; Between sealing plate 2 and support, be provided with O RunddichtringO II 5; End between sealing plate 2 and translation seal axle 1 is equipped with oilless bearing 6; Middle part between sealing plate 2 and translation seal axle 1 is provided with seal washer 3, O RunddichtringO I 4, and O RunddichtringO I4 is contained in the middle of two seal washers 3.
Seal washer () can adopt materials such as polytetrafluoroethylene pad.
By O RunddichtringO I 4, two seal washers 3, O RunddichtringO I 4 forms one group of seal group in the middle of being contained in two seal washers 3.Seal group can only be established one group, and many groups also can be set.Present embodiment (as shown in the figure) is two groups of seal group.
Operation principle: when translation seal axle 1 moves up and down, because seal washer 3 and oilless bearing 6 guiding, seal group decrement between translation seal axle 1 and the sealing plate 2 is kept evenly, and seal washer 3 can prevent that also O RunddichtringO I 4 is extruded, and causes gas leak phenomenon simultaneously.After increasing oilless bearing 6, can make guiding more reliable, guarantee that the seal group decrement keeps evenly, thereby guaranteed sealing effectiveness.
Therefore the utlity model has simple in structurely, parts machining is convenient, installs simply, and sealing is reliable, Cost, the characteristics such as transmission efficiency raising.
