Description

Technical Field

[0001] The utility model relates to the field of box-type transformer top cover structures, in particular to a detachable top cover structure of a waterproof and dustproof segmented box-type transformer. Background Art

[0002] At present, outdoor box transformers are protected by prefabricated European box bodies. The box body is divided into several functional small chambers, and multiple chambers are arranged separately, such as high-voltage cable chamber, load switch chamber, transformer chamber, low-voltage chamber, etc. The box cover on the top of the box body is an integrated design. Although it is easy to assemble, there are other problems during use. For example, when one of the chambers needs to be repaired or replaced, the entire box cover must be removed. After the box cover is removed, other chambers will have no roof protection and are easily affected by the outside world. This problem is particularly important for power stations within the power grid, because the power outage application process and time consumption will directly and negatively affect the power generation efficiency, and the noise reduction effect is poor. The electromagnetic noise and structural vibration generated by the operation of the transformer in the box transformer are relatively large, and the low-frequency component is heavy. If the noise is transmitted to the outside through the box cover, it will cause noise pollution to the surrounding environment. We propose a detachable top cover structure for a waterproof and dustproof segmented box transformer. Utility Model Content

[0003] The utility model aims to provide a detachable top cover structure of a waterproof and dustproof segmented box-type transformer, which solves the problem that the existing detachable top cover structure is an integrated structure and has a poor noise reduction effect.

[0004] The above technical purpose of the utility model is achieved through the following technical scheme: a detachable top cover structure of a waterproof and dustproof segmented box transformer, including a base plate, the top of the base plate is integrally formed with two guide frames, the top of the guide frame is slidably sleeved with a cover plate, the inside of the cover plate is welded with an inner frame body, the bottom of the cover plate is bonded with a sealing ring, the inside of the inner frame body is filled with sound-absorbing cotton, the inside of the inner frame body is welded with a sound insulation board, and the bottom of the sound insulation board is provided with sound-absorbing holes.

[0005] By adopting the above technical solution, the covers above different chambers can be opened independently, which is convenient for personnel to carry out maintenance, and has good waterproof and dustproof effects between the box frame and the sound insulation effect. It improves the surrounding environment and is highly practical.

[0006] The utility model is further configured as follows: a fixing bolt is provided through the interior of the inner frame, and a threaded groove used in conjunction with the fixing bolt is provided inside the guide frame.

[0007] By adopting the above technical solution, the cover plate can be fixed by setting the fixing bolts and the threaded grooves, thereby preventing the cover plate from shifting up and down when it is vibrated after installation.

[0008] The utility model is further configured as follows: a lifting ring is welded on the top of the cover plate.

[0009] By adopting the above technical solution and providing the lifting ring, it is convenient for personnel to lift the cover plate using lifting equipment.

[0010] The utility model is further configured as follows: both sides of the top of the cover plate are inclined downward.

[0011] By adopting the above technical solution, rainwater falling on the top of the cover plate can slide down quickly, thus preventing rainwater from being retained on the top of the cover plate.

[0012] The utility model is further configured as follows: the sealing ring is made of polytetrafluoroethylene.

[0013] By adopting the above technical solution, the sealing ring has good heat resistance, cold resistance and excellent acid and alkali resistance.

[0014] The utility model is further configured as follows: the sound-absorbing cotton is made of glass fiber material.

[0015] By adopting the above technical solution, the sound-absorbing cotton has the characteristics of good sound-absorbing effect, strong heat resistance and excellent corrosion resistance.

[0016] The utility model is further configured as follows: the surfaces of the substrate and the cover plate are sprayed with a hydrophobic coating.

[0017] By adopting the above technical solution and providing a hydrophobic coating, the waterproof and moisture-proof properties of the surfaces of the substrate and the cover plate can be improved.

[0018] In summary, the utility model has the following beneficial effects:

[0019] 1. The utility model fixes the base plate on the top of the box frame during installation, fixes the sealing ring in the cover plate by hot melt adhesive after the base plate is fixed, lifts the cover plate and puts it on the guide frame after the sealing ring is fixed, and drops the cover plate down to fit the top of the base plate after the cover plate is put on. Then the personnel inside the box frame screw the fixing bolts into the threaded grooves to complete the fixation. The same method can be used for installing other cover plates, so that the cover plates above different chambers can be opened independently, which is convenient for personnel to inspect and repair, and has a good waterproof and dustproof effect between the box frame.

[0020] 2. The utility model realizes that when the transformer inside the box-type transformer generates noise, the noise will first pass through the sound insulation board when it propagates outward through the cover plate. The sound-absorbing holes opened in the sound insulation board can initially reduce the noise. After passing through the sound-absorbing holes, the noise will hit the sound-absorbing cotton. The sound-absorbing cotton can absorb the noise and isolate the sound waves, thereby achieving good sound insulation effect, improving the surrounding environment, and having high practicality.
