Description

Technical Field

[0001] The utility model belongs to the technical field of transformer oil tanks, and in particular relates to a combined transformer oil tank shell. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core (magnetic core). Its main functions include voltage conversion, current conversion, impedance conversion, isolation and voltage stabilization (magnetic saturation transformer), etc. It can be divided into power transformers and special transformers according to its use.

[0003] The heat sink or heat sink plate on the transformer oil tank in the prior art is fixedly welded on the outer wall of the transformer oil tank. Although the fixed welding method is firm, the cost and intensity of production and processing are relatively high; secondly, after long-term use, the heat sink on the transformer oil tank is prone to damage or maintenance problems, and the heat sink plates in the prior art are fixedly welded, so there is a problem of inconvenient maintenance.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0006] A combined transformer oil tank shell comprises a transformer oil tank, wherein four outer walls of the transformer oil tank are provided with detachably mounted heat dissipation components, the heat dissipation components comprising two upper and lower mounting seats and a plurality of heat dissipation plates arranged between the two upper and lower mounting seats, the mounting seats are fixedly arranged on the side wall of the transformer oil tank, and the plurality of heat dissipation plates are distributed on the side wall of the transformer oil tank in a state of equal spacing.

[0007] As a preferred embodiment of the utility model, the upper and lower mounting seats are fixedly welded on the side wall of the transformer oil tank, the upper and lower mounting seats are arranged in a symmetrical state, the side wall surface of the upper and lower mounting seats close to each other is hollow, and one end of the upper and lower mounting seats is also hollow.

[0008] As a preferred embodiment of the utility model, a rotating part in a convex state is integrally formed at one end of the heat dissipation plate, and the rotating part is always in contact with the outer wall of the transformer oil tank. Limit rods are fixedly welded on the upper and lower end walls of the rotating part, and the limit rods are located on the center line of the center of the circle of the rotating part. The limit rods are arranged in the corresponding mounting seat.

[0009] As a preferred embodiment of the utility model, a positioning rod is fixedly arranged in the cavity of the mounting seat, one end of the positioning rod is fixedly installed together with the inner side wall of the cavity of the mounting seat, a limiting hole is provided on the limiting rod, the inner diameter of the limiting hole is larger than the outer diameter of the positioning rod, and the limiting rod is inserted into the outer wall of the positioning rod through the limiting hole.

[0010] As a preferred embodiment of the utility model, springs are evenly spaced and inserted into the outer wall of the positioning rod. The springs are located between the limiting rods of two adjacent heat sinks. An external thread is provided on the other end of the positioning rod. A locking nut is screwed to the external thread of the positioning rod. The end cover is fixed to the hollow side of the mounting seat by screws.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The heat dissipation assembly is installed on the side wall of the transformer oil tank in a detachable manner, so there is no need to weld each heat dissipation plate to the side wall of the transformer oil tank at equal intervals, which reduces the overall production and processing intensity and labor intensity of the transformer oil tank of this scheme, and also saves more production and processing costs.

[0013] 2. The heat sink, limit rod, positioning rod and spring provided in this scheme can adjust the number of heat sinks installed or the distance between two adjacent heat sinks. When the number of heat sinks increases or decreases, it is only necessary to increase the number of heat sinks installed on the positioning rod or reduce the number of heat sinks. At the same time, the adjustment of the distance between two adjacent heat sinks can not only be controlled by the number of heat sinks installed, but also can be achieved by replacing springs with different coefficients. Therefore, it can better meet the actual installation and use requirements.

[0014] 3. Through the heat dissipation assembly provided in this scheme, the heat dissipation plate can be more conveniently replaced or maintained during later use, reducing the overall disassembly and maintenance of the transformer oil tank. Only the heat dissipation plate needs to be disassembled and maintained, thereby improving the practicality of this scheme.

[0015] The specific implementation modes of the present utility model are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0025] A combined transformer oil tank housing, such as Figure 1 , Figure 2 As shown, it includes a transformer oil tank 10, and the four outer walls of the transformer oil tank 10 are each provided with a detachably mounted heat dissipation assembly 20, the heat dissipation assembly 20 includes two upper and lower mounting seats 25 and a plurality of heat dissipation plates 21 arranged between the two upper and lower mounting seats 25, the mounting seats 25 are fixedly arranged on the side wall of the transformer oil tank 10, and the plurality of heat dissipation plates 21 are distributed on the side wall of the transformer oil tank 10 at equal intervals.

[0026] like Figure 2 , Figure 3 As shown, the upper and lower mounting seats 25 are both fixedly welded on the side wall of the transformer oil tank 10, and the upper and lower mounting seats 25 are arranged in a symmetrical state. The side wall surfaces of the upper and lower mounting seats 25 that are close to each other are hollowed out, and one end of the upper and lower mounting seats 25 is also hollowed out. A rotating portion 24 in a convex state is integrally formed at one end of the heat dissipation plate 21, and the rotating portion 24 is always in contact with the outer wall of the transformer oil tank 10. The upper and lower end wall surfaces of the rotating portion 24 are fixedly welded with a limit rod 22, and the limit rod 22 is located on the center line of the center of the rotating portion 24, and the limit rod 22 is arranged in the corresponding mounting seat 25.

[0027] like Figure 4 , Figure 5 , Figure 6As shown, a positioning rod 27 is fixedly arranged in the cavity of the mounting seat 25, one end of the positioning rod 27 is fixedly installed with the inner side wall of the cavity of the mounting seat 25, and a limiting hole 23 is provided on the limiting rod 22, the inner diameter of the limiting hole 23 is larger than the outer diameter of the positioning rod 27, and the limiting rod 22 is inserted into the outer wall of the positioning rod 27 through the limiting hole 23. Springs 28 are also inserted into the outer wall of the positioning rod 27 at equal intervals, and the springs 28 are located between the limiting rods 22 of two adjacent heat sinks 21. The other end of the positioning rod 27 is provided with an external thread, and a locking nut 29 is screwed to the external thread of the positioning rod 27, and the end cover 26 is fixedly installed with the hollow side surface of the mounting seat 25 by screws.

[0028] When in use, the heat dissipation assembly 20 is installed on the side wall of the transformer oil tank 10 in a detachable manner, so there is no need to weld each heat dissipation plate 21 to the side wall of the transformer oil tank 10 at equal intervals, thereby reducing the overall production and processing intensity and labor intensity of the transformer oil tank 10 of this scheme, and also saving more production and processing costs.

[0029] Specifically, when installing the heat sink 21, align the limiting rod 22 on each heat sink 21 and put it into the cavity of the mounting seat 25, align the limiting hole 23 on the limiting rod 22 with the positioning rod 27, and then insert it. After insertion, the spring 28 is sleeved on the outer wall of the positioning rod 27. After all the heat sinks 21 are installed in this way, the locking nut 29 is screwed into the external threaded end of the positioning rod 27, and the outermost heat sink 21 is tightened and fixed. Finally, all the heat sinks 21 can be squeezed and fixed. The arc-shaped end of the rotating part 24 will always be in contact with the outer wall of the transformer oil tank 10, thereby ensuring the transfer and conduction of heat.

[0030] The heat sink 21, limit rod 22, positioning rod 27 and spring 28 provided in the present solution can adjust the number of heat sinks 21 installed or the distance between two adjacent heat sinks 21. When the number of heat sinks 21 increases or decreases, it is only necessary to increase the number of heat sinks 21 installed on the positioning rod 27 or reduce the number of heat sinks 21. At the same time, the distance adjustment between two adjacent heat sinks 21 can not only be controlled by the number of heat sinks 21 installed, but also can be achieved by replacing springs 28 with different coefficients. Therefore, it can better meet the actual installation and use requirements.

[0031] In this solution, by providing the heat dissipation assembly 20, the heat dissipation plate 21 can be more conveniently replaced or maintained during later use, thereby reducing the overall disassembly and maintenance of the transformer oil tank 10. Only the heat dissipation plate 21 needs to be disassembled and maintained, thereby improving the practicality of this solution.
