Electric appliance 27.
The end face of the oil conservater 21 be equipped with oil level indicator 28, the oil level indicator 28 be pipe structure, pipe structure it is upper
End and lower end are connected to the top and bottom of oil conservater 21.Oil level indicator 28 is for observing 21 oil surface level of oil conservater.It is above-mentioned
Oil level indicator 28 can use pipe type oil-level gauge 28, or with magnetic-type oil level indicator 28 simultaneously band signal contact.
Corrugation radiator 12 includes corrugated plate group and oil collecting pipe, and oil collecting pipe includes oil inlet pipe 13 and oil outlet pipe 14, is divided
It is not connected to the top and bottom end of corrugated plate group.Oil inlet pipe 13 and oil outlet pipe 14 are made of square steel, and axial the one of square steel
Welding steel closing, axial other end welded flange is held to be used for connecting butterfly valve.In other embodiments, it can not also be welded on square steel
Acting flange, when use, are directly welded in the trepanning of tank wall.Four sides of square steel are plane, and length is equipped on three sides
Hole.
The material of corrugated plate 11 is 1.2mm 1.5mm steel plates（The trade mark is not less than ST14）, the bending on plane steel plate
Go out the U-shaped bending 15 of multiple protrusions, U-shaped bending 15 forms oil groove 119, the depth of oil groove 119（That is the height of wave wing protrusion plane
Degree）Range is generally between 170mm to 350mm, and oil groove 119 inner wall distance is generally 6mm, and the spacing between oil groove 119 is minimum
For 45mm.Oil groove 119 on each corrugated plate 11 folds rear upper and lower side welded closure.The upper and lower side end of oil groove 119 is respectively with two
Root round steel 16 is spot-welded together, for preventing oil groove 119 to be formed by the deformation of wave wing.Certainly, the thickness of corrugated plate, length etc.
Parameters can also be changed according to actual needs.
It is welded with vertical supporting beam 17, vertical supporting beam 17 between the bottom surface and the top surface of oil outlet pipe 14 of oil inlet pipe 13
Can be rectangle steel, channel steel or the steel plate for being bent into U-shaped, the side plate of steel plate or the side plate of channel steel are connect with the corrugated plate 11.
Vertical supporting beam 17 uses channel steel in the present embodiment.Oil inlet pipe 13, oil outlet pipe 14 and vertical supporting beam 17 form radiator
The vertical side of skeleton, oil inlet pipe 13 and oil outlet pipe 14 and the vertical side of vertical supporting beam 17 are coplanar so that corrugated plate
11 each lateral edges can fit on radiator skeleton, and the edge of corrugated plate 11 is realized by radiator skeleton to be closed, meanwhile,
The horizontal both sides of the edge of two panels corrugated plate 11 are closed by vertical supporting beam 17, and the interval between corrugated plate is made to form closing chamber,
Closing chamber communicates with the oil groove on corrugated plate and oil pocket is collectively formed with oil groove.It, can be in order to improve the intensity of radiator skeleton
Setting is connected to the reinforcing rib between at least two of oil inlet pipe 13, oil outlet pipe 14 and vertical connector in interval 18.
In the slot hole being arranged on the side of square steel, the slot hole on the side of horizontal direction both sides vertically extends
Slot hole forms oil groove communication port 19, the side of the notch opening's edge and oil collecting pipe horizontal direction both sides of 11 finishing bathtray 119 of the corrugated plate
Face close fit, the oil groove 119 on corrugated plate 11 are connected to the oil groove communication port 19.The bottom surface of square steel is equipped with interval and is connected to
Mouth 110, the interval communication port 110 and oil groove communication port 19 are arranged separately to each other on the tube wall of oil collecting pipe.Square steel does not open length
Platform sling and fixed plate are welded in the one side in hole, in order to lift by crane corrugation radiator 12 and consolidating convenient for 12 component of corrugation radiator
It is fixed.
Oil conservater 21 in the present invention is all-sealed, has pouring orifice 24 and gas vent 23, apnea mouth not to connect moisture absorption
Device.Different from traditional oil conservater 21, which fills transformer oil when using, and due to being not provided with pneumostome, does not have
The function of the transformer oil volume change because caused by lifting oil temperature is repaid in the next choice, and function is to ensure that under transformer body and casing
Portion is reliably dipped in oil.The oil conservater 21 use when with corrugation radiator 12 coordinate, it can be achieved that high-power transformer it is hermetically sealed.
In other embodiments of the invention, gas vent can not also be set on oil conservater, it can be real by other means
Existing oiling, such as oil conservater is vacuumized into rear oiling.In addition, gas vent can also replace with the form of air relief cock.In other realities
It applies in example, pouring orifice can not also be set on oil conservater, oiling is realized by Oil Tank connector.
In the present invention described in the embodiment of the embodiment of the oil conservater of oil-immersed transformer, that is, above-mentioned oil-immersed transformer
Oil conservater, details are not described herein again for concrete structure.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not limited to this hair
