Description
Technical field
The present invention relates to a kind of power transmitting device of compressed gas insulation, include closure, the phase conductor that closure centers on of a flange port and the internal flange tegmental wall that faces flange port is arranged and, first fin is being arranged on the internal flange tegmental wall and externally on the flange tegmental wall second fin is being arranged back to the blind flange of the external flanges tegmental wall of flange port.
Background technology
By the known this device of Japanese 08-223719 abridgments of specifications.The device there has a closure that comprises a blind flange.In order to increase the surface, settle the fin that constitutes by curved lever in the blind flange inboard and the outside.Cause dispelling the heat better by increasing the surface.In order to promote heat radiation, the quantity that is necessary to strengthen fin or increases fin.These just can realize the position-based situation under some condition.
Therefore the technical problem to be solved in the present invention is, a kind of power transmitting device of compressed gas insulation is provided, and it can more effectively utilize the fin heat radiation.
Summary of the invention
Take following measures to be solved by the above-mentioned technical problem of the present invention in a kind of power transmitting device of compressed gas insulation: internal flange tegmental wall dome-shaped drum above flange port is protruding.
Closure fluid seal ground is around phase conductor.Therefore can be in airtight system of the inner formation of closure.At the inner electrical insulation fluids that uses of closure, for example when insulating oil or insulating gas, can impel closure inside that higher insulating capacity is arranged.Fluid can flow around phase conductor.Except that electric insulation, fluid can also be taken away the heat of phase conductor.
The dome-shaped drum of the wall of internal flange tegmental wall above flange port is protruding, provides a spendable additional volume to closure.This additional volume can hold additional fluid.Because Fluid Volume strengthens, and increases absorbable heat.These heats that increase can correspondingly transmit in closure inside.When temperature in the power transmitting device rises, make the inner Fluid Volume vaporization that increases of closure.
Additionally, by being in the fin in the bulging convex region, the heat in the flange tegmental wall is also added in the closure.Drum is protruding can advantageously to be designed to spill basically.
Can stipulate advantageously that in addition first fin shields in dome-shaped drum is protruding.
Dome-shaped drum is protruding to provide protection machinery and that also provide electricity to be situated between in case of necessity for first fin.The moulding of fin and protruding the adapting of drum.Rouse the rigidity that protruding arch helps to improve fin here.In this case, fin can be in the protruding inside of drum of spill basically fully.Therefore external force can not act directly on first fin.Fin with many ledges becomes the object that is unfavorable for that electricity is situated between.So except the first fin mechanical masking, they can also be situated between by the blind flange electricity and shield.
In this structure, all first fin are in the flange ring top that stops blind flange.Therefore first fin is in inside, a blind zone fully.Because first fin leaves the flange face in the flange ring there, so this blind flange also can be existing closure installing afterwards.
Can stipulate advantageously that in addition first and/or second fin and flange tegmental wall integral type are shaped.
Monolithic molding can provide the heat bridge of low loss between fin and flange tegmental wall.Heat can directly exchange between first and second fin.Can make blind flange easily in addition.
Can stipulate advantageously that correspondingly with one first fin set one second fin, ground aligned with each other, their bonding pads on inside or external flanges tegmental wall is mutually opposed.
Inside and outside fin runs through blind flange and is disposed aligned, can the straight line heat transfer between the fin that each correspondence sets in fin inside.Avoid hindering in the blind flange focus of heat extraction thus.The zone that the fin that described bonding pad is those in flange tegmental wall separately here joins.
Can stipulate advantageously that also blind flange is the foundry goods of a conduction.
The conduction foundry goods can the same ground connection with closure.Therefore obtain a kind of device of touch-safe, it allows contact with being safe from danger.
Another favourable design can stipulate that flange is stamped a flange ring.
The en plaque flange can be general and be applicable to the big power of transmitting.Can constitute the en plaque flange by the flange ring that utilizes blind flange.Possibility is provided thus, closes described closure by blind flange.
Be in the fluid of closure inside, for example insulating gas such as SF
6, can apply the high pressure of some bar.When blind flange correspondingly seals, even under high pressure fluid also can not leak.
For clamping plate sheet flange, the flange face that will compress is run through by some holes on flange ring each other, and they are used for construction bolt.By the fixing sheet flange of fishbolt.
Description of drawings
Schematically illustrate embodiments of the invention and detailed description subsequently below in the accompanying drawings.
Wherein:
Fig. 1 represents the end view of the power transmitting device of compressed gas insulation; And
Fig. 2 represents to cut the section that illustrates open by blind flange.
Embodiment
The power transmitting device of the compressed gas insulation of representing among Fig. 1 has a closure 1.Closure 1 is designed to tubulose basically.In addition also can adopt other any designs.Closure 1 is coaxial to be arranged in longitudinal axis 2 ground.Closure 1 is coaxial in longitudinal axis 2 and with respect to the phase conductor 3 of closure 1 electric insulation ground layout around one.Closure 1 filling is a kind of to apply the insulating gas of high pressure with respect to its surrounding environment, as SF
6
Except using difform closure, can also change the moulding and the quantity of phase conductor.For example bus-bar section, switch contact etc. also can play phase conductor.
Closure 1 list area is outside established flange port 4.Flange port 4 is the boundary with the flange ring.In order to close flange port 4, fluid mounting flange lid 5 hermetically on flange ring.
Flange port 4 has circular cross section.The flange ring of flange port 4 is coaxial in vertical pivot 8 ground orientations.Vertical pivot 8 for example with longitudinal axis 2 orientation that meets at right angles.It is the boundary with the flange ring that blind flange 5 faces flange port 4 those ends at it.Blind flange 5 clamps by bolt each other with the flange ring of flange port 4.Between flange ring, adorn seal, therefore between flange ring, cause the connection of fluid seal.
Second fin 7 that is located on the external flanges tegmental wall 6 is distinguished each at a plane internal shaping.The arrangement parallel to each other of these planes.Each fin 7 has approximately uniform height.Therefore second fin 7 is along protruding banded extension of dome-shaped drum.
Fig. 2 represents to cut the section that illustrates open by blind flange 5.Blind flange 5 has the protruding structure of a kind of dome-shaped basically drum.Internal flange tegmental wall 9 dome-shaped spill basically ground above the flange ring of blind flange 5 extends.On internal flange tegmental wall 9, establish first fin 10.First fin 10 is designed to the shape and the orientation parallel to each other on plane.Each first fin 10 just in time with one second fin, 7 corresponding setting, the fin that here is relative to each other always in a plane ground aligned with each other directed.Therefore the fin that sets of corresponding to each other seem like with flange tegmental wall 6,9 " intersecting ", and continue in flange tegmental wall 6,9 both sides.First fin 10 has different length, and these length are tuned as, and the free end that protrudes out from the spill drum is finished in same plane.Here, this plane parallel in the clamping area of blind flange 5 flange rings and with vertical pivot 8 orientation that meets at right angles.In addition, the intra-zones that blind flange 5 electricity are situated between and shield were passed through thereby make first fin 10 be in one in this plane before the protruding the place ahead of drum is in the clamping area of blind flange 5 flange rings.
