background
The transformer and the reactor are used as important equipment of power transmission equipment, the traditional design generally only has one oil tank, components such as a coil, a reactor body and the like are placed in the oil tank, and only one insulating medium is used as an internal component. However, when two or more kinds of insulating media are used as the internal components, the dual-structure design of the internal and external oil tanks is required because the different properties of the insulating media cannot be mixed.
The existing double structure of the inner oil tank and the outer oil tank has the problems of installation deviation, poor sealing property, easy oil leakage and the like due to the adoption of two or more than two insulating media, the sealing property and the strength property of the double structure can not meet the requirements of the existing national standard, and the safe and stable operation of a product can not be ensured.
Disclosure of Invention
Aiming at the defects of installation deviation, poor sealing performance, easy oil leakage and the like of an internal and external oil tank dual structure in the prior art, the invention aims to provide an oil tank rabbet flange structure which can ensure that a sealing surface of an external oil tank is in complete contact with an adjusting flange and does not generate oil leakage.
In order to solve the technical problems, the invention adopts the technical scheme that:
The invention relates to an oil tank rabbet flange structure which comprises an internal oil tank fixing flange, an external oil tank adjusting flange, a mounting bolt and a sealing gasket, wherein the internal oil tank fixing flange is in contact with a sealing surface of an internal oil tank and is arranged on the wall of the external oil tank through the mounting bolt, and the external oil tank adjusting flange is sleeved on the internal oil tank fixing flange.
A first sealing gasket is arranged between the sealing surface of the inner oil tank fixing flange and the sealing surface of the inner oil tank 1.
And a second sealing gasket is arranged between the external oil tank adjusting flange and the internal oil tank fixing flange.
The external oil tank adjusting flange is fixedly connected to the external oil tank.
The invention has the following beneficial effects and advantages:
1. The invention realizes the reliable installation of the double structure of the internal oil tank and the external oil tank, solves the structural problem that two or more than two insulating media exist in the oil tank, can also be properly adjusted when the interfaces of the internal oil tank and the external oil tank cannot be completely corresponding in the installation process, provides a direct operation interface for leading out the components of the internal oil tank, and is convenient for maintenance and inspection in long-term operation.
The invention 2 has flexible and simple installation, adopts rigid flange sealing connection, not only ensures that the internal and external oil tanks can bear the strength requirement of national standard, but also ensures the sealing property of the internal and external oil to prevent the risk of oil leakage.
Drawings
FIG. 1 is a front view of an internal and external fuel tank mounting structure in accordance with an embodiment of the present invention;
FIG. 2 is a top view of the present FIG. 1;
Fig. 3 is an enlarged schematic view of part I in fig. 2.
Wherein, 1 is inside oil tank, 2 is outside oil tank, 3 is inside oil tank mounting flange, 4 are outside oil tank adjusting flange, 5 are first sealed pad, 6 are the construction bolt, 7 are the second sealed pad, 8 are outside oil tank wall, 9 are inside oil tank wall.
Detailed Description
The invention is further elucidated with reference to the accompanying drawings.
As shown in fig. 1-2, the oil tank rabbet flange structure of the invention comprises an inner oil tank fixing flange 3, an outer oil tank adjusting flange 4, a mounting bolt 6 and a sealing gasket 5, wherein the inner oil tank fixing flange 3 is contacted with a sealing surface of an inner oil tank 1 and is mounted on the wall of the outer oil tank 2 through the mounting bolt 6, and the outer oil tank adjusting flange 4 is sleeved on the inner oil tank fixing flange 2.
As shown in fig. 3, a first gasket 5 is arranged between the sealing surface of the inner tank fixing flange 3 and the inner tank 1; a second sealing gasket 7 is arranged between the external oil tank adjusting flange 4 and the internal oil tank fixing flange 2; the external fuel tank adjusting flange 4 is fixedly connected to the external fuel tank 2.
According to the invention, the inner oil tank fixing flange 3 is contacted with the sealing surface of the inner oil tank 1, and the inner oil tank fixing flange is installed by the installation bolt 6, so that the opening of the inner oil tank can be led out to connect a cable with an external electrical element, and the problem of oil leakage is avoided.
The flange is adjusted to outside oil tank 4 can appear certain mounting dimension deviation when inside oil tank 1 is installed in outside oil tank 2, uses the flange of adjusting to adjust with outside oil tank this moment to adopt the welding mode to fix, guarantee that the sealed face of outside oil tank contacts completely with the flange of adjusting, does not produce the oil leakage.
As shown in fig. 1 to 2, when the internal fuel tank 1 is placed in the external fuel tank 2, the internal fuel tank fixing flange 3 and the first gasket 5 are first attached, and the internal fuel tank fixing flange 2 is tightened to the wall of the internal fuel tank 1 by the attachment bolts 6, thereby forming a seal surface of the internal fuel tank 1.
As shown in fig. 3, the outer tank adjustment flange 4 is fitted over the inner tank fixing flange 2 while the second gasket 7 is installed, and then the inner tank fixing flange 3 and the outer tank adjustment flange 4 are welded together to form a sealing surface of the outer tank 2.
Finally, the external tank adjustment flange 4 is welded to the external tank 2, forming a whole.
The invention is mainly used for transformer and reactor products with oil immersed type internal and external double oil tank structure, is flexible and simple to mount, adopts rigid flange sealing connection, not only ensures that the internal and external oil tanks can bear the strength requirement of national standard, but also ensures the sealing property of the internal and external oil to prevent the risk of oil leakage.
