The outer cover locating part 11 and outer cover buckle 12 for connecting outer cover are formed on the outer edge of end plate 2.Outside end plate 2
Rectangle recess is formed on edge, outer cover buckle 12 is formed in recess；Outer cover locating part 11 is rectangular cam, is formed in end plate
On 2 outer edges, and it is spaced apart one by one with outer cover buckle 12.
End plate 2 is formed with the connecting hole 13 of perforation in the four corners of interior frame 3, is formed with correspondence on the outer surface of end plate 2
In the outer rim 14 of groove 5, the height of outer rim 14 is significantly less than interior frame, is mainly used for providing enough parts for end plate 2
Thickness forms groove 5, and to be divided between the flanging 15 of 2 surrounding of outer rim 14 and end plate by several floors 16 be in the first marker space
Domain, being divided between outer rim 14 and the rectangle position 17 in 2 outer surface of end plate center by floor 16 is in the second separated region.This knot
Structure while middle section has enough thickness to form groove 5, can effectively reduce the dosage of injected plastics material in guarantee end plate,
And guarantee the insulation performance and mechanical strength of end plate 2.
In addition, two pairs of opposite attached buckles 18 are formed on the outer surface of end plate 2, in order to install in oil tank of transformer
The other component (not shown) of portion's package assembly.
It is the outer surface schematic diagram of a side end panel shown in Fig. 6 please also refer to Fig. 8 to Figure 12, Fig. 8；Fig. 9 is shown in Fig. 8
The inner surface schematic diagram of end plate；Figure 10 is the outer surface schematic diagram of another side end panel shown in Fig. 6；Figure 11 is end plate shown in Figure 10
Inner surface schematic diagram；Figure 12 is the partial enlarged view of end plate upper right comer region shown in Figure 11.
When being assembled, left and right cabinet is directed at the groove 5 on left and right end plate 2, the two is plugged in together, then
It by the connecting hole 13 of 3 four corners of interior frame, is reinforced, cabinet 1 and end plate 2 can be assembled in using connectors such as screws
Together, after assembling, the first limit body 6, the second limit body 7 and third limit body 8 can limit cabinet 1 relative to end plate 2 or end
Plate 2 is mobile relative to cabinet 1, combines the two even closer, is not easy to misplace, meanwhile, the first limit body 6 and the second limit body
7 can be also used for mounting circuit boards, and outer cover is equipped between notch corresponding with outer cover locating part 11 or through-hole, with end plate 2
It is attached by outer cover buckle 12.
It is verified by test of many times, in terms of insulation, the present invention is more relatively reliable than original scheme, caused by insulation deficiency
Sparking rate is reduced to 0% by original 20%, greatly reduces equipment failure rate, while reducing maintenance loss working hour (because of maintenance
When need replacing all PC components, maintenance man-hours are almost identical as the total production hour of single-piece, and maintenance cost is high), assembling
It is also easier and easily operated than original scheme in disassembly.
What needs to be explained here is that above-mentioned cabinet 1 and end plate 2 are polyformaldehyde material, polyformaldehyde material is selected, on the one hand
It can obtain optimal insulation effect, another aspect polyformaldehyde material ratio PC material softness, during assembly and disassembly, each part
Sharp edge acute angle will not all scratch the hand of worker.
Above-described embodiment is only preferred embodiment of the invention, is specifically not limited thereto, on this basis can be according to reality
It needs to make to have and targetedly adjust, to obtain different embodiments.For example, according to actual needs, limiting component
Quantity can be further increased or be reduced, alternatively, limiting component is designed to other shapes, etc..Due to mode in the cards
It is more, it just no longer illustrates one by one here.
In addition to above-mentioned oil tank of transformer assembled inside structure, the present invention also provides a kind of transformers, including transformer winding
And oil tank of transformer, wherein the oil tank of transformer is equipped with oil tank of transformer assembled inside structure described above, remaining structure
Refer to the prior art, and repeats no more herein.
Oil tank of transformer assembled inside structure provided by the present invention and transformer are described in detail above.Herein
In apply that a specific example illustrates the principle and implementation of the invention, the explanation of above example is only intended to sides
Assistant solves core of the invention thought.It should be pointed out that for those skilled in the art, not departing from this hair
