Abstract
The utility model discloses a kind of three-phase oil-immersed power transformers, including transformer case, the transformer body inside transformer case, set on the buffer of transformer case lower bottom part, the pedestal below buffer, for the steel plate case lid, the sealing device for fixing transformer body and steel plate case lid and the sheath assembly set on the steel plate box side of covering of hermetically-sealed- transformer ontology.The utility model improves case lid fixed form, overcomes traditional transformer that the defect of case lid and transformer body dislocation easily occurs during transportation.
Description
Technical field
The utility model relates to transformer manufacture fields, and in particular to a kind of three-phase oil-immersed power transformer.
Background technique
Transformer is a kind of principle using electromagnetic induction to change the device of alternating voltage, existing oil-immersed transformer
Cover board encapsulation carries out transformer body and case using the pressing force between nail pressing and transformer body, while using the frictional force of screw rod
Fixation between lid, due to transformer installation before for assembling improve transports for long-distance again, often infield farther out and transformer compared with
Weight, jolt frequent occurrence during transportation cause case lid loosen and transformer body be displaced the case where, to transformer install
Reliability have an impact, so transformation will be increased substantially if designing a kind of novel power transformer overcomes above-mentioned problem
The structural reliability of device during transportation.
Utility model content
In view of the above technical problems, the utility model provides a kind of three-phase oil-immersed power transformer, comprising:
Transformer case, the transformer body inside transformer case, set on the buffering of transformer case lower bottom part
Device, the pedestal below buffer, for the steel plate case lid of hermetically-sealed- transformer ontology, for fixing transformer body and steel plate
The sealing device of case lid and sheath assembly set on the steel plate box side of covering.
Preferably, transformer body lower part is equipped with grounding base.
Preferably, sealing device includes that hand hole flange plate, the positioning support connecting with steel plate cover bolt and card are set
Hand hole flange plate and steel plate case lid are integrally connected by the insulation sleeve between positioning support and steel plate case lid, positioning support, positioning
Bearing bottom surface is fixedly connected with transformer body upper surface.
Preferably, sheath assembly includes low-tension bushing and bushing.
Preferably, hand hole flange plate upper surface is equipped with oil level indicator.
Preferably, transformer case side is equipped with radiator, is equipped with below pedestal for mobile movable pulley.
The utility model has the advantages that
1, three-phase oil-immersed power transformer leakage field is small, high mechanical strength, and anti-short circuit capability is strong.
2, replace firm banking bracket with movable pulley, carried convenient for long-distance transport and installation up and down.
3, being positioned using hand hole flange replaces the case lid of traditional transformer to increase positioning, and reliability is higher, while also saving
Transformer oil mass.
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings.
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is enlarged diagram at A in Fig. 1.
Digital representation in figure:

Specific embodiment
As illustrated in fig. 1 and 2, the utility model includes transformer case 10, the transformer inside transformer case 10
Ontology 1, the pedestal 4 set on 3 lower section of buffer, is used for hermetically-sealed- transformer sheet at the buffer 3 set on 10 lower bottom part of transformer case
The steel plate case lid 14 of body 1, the sealing device for fixing transformer body 1 and steel plate case lid 14 and be set to steel plate case lid 14
The sheath assembly of side.1 lower part of transformer body is equipped with grounding base 6, and sealing device includes hand hole flange plate 11 and steel plate case lid
The positioning support 12 of 14 bolts 13 connection and the insulation sleeve 15 being arranged between positioning support 12 and steel plate case lid 14, positioning support
12 are integrally connected hand hole flange plate 11 and steel plate case lid 14, and 12 bottom surface of positioning support and 1 upper surface of transformer body are solid
Fixed connection.Sheath assembly includes low-tension bushing 8 and bushing 9, and 11 upper surface of hand hole flange plate is equipped with oil level indicator 2, is become
10 side of depressor shell is equipped with radiator 7, is equipped with below pedestal 4 for mobile movable pulley 5.
The utility model improves the connection type of steel plate case lid 14 Yu transformer body 1, and traditional transformer is in case lid
It when being connect with transformer body 1, is positioned using the case lid mode of rising, the front-back staggered displacement of Yi Fasheng case lid, and this is practical new
Type uses hand hole flange plate 11 and positioning support 12, shortens the distance between transformer body 1 and steel plate case lid 14, together
Shi Shoukong flange plate 11 can effectively position transformer body 1 and the upper and lower all around of case lid, overcome traditional transformation
The positioning defect of device.
Various modifications to these embodiments will be readily apparent to those skilled in the art, herein
Defined General Principle can be real in other embodiments without departing from the spirit or scope of the present utility model
It is existing.
