Description
Technical field
The utility model relates to field transformer, particularly a kind of transformer base structure.
Background technology
Transformer manufactures according to electromagnetic induction principle.Magnetic energy is the medium of electric energy conversion, and iron core is the magnetic circuit part of transformer, and Main Function is magnetic conduction, and it is made up of the cold-reduced silicon sheet that magnetic permeability is very high.Along with transformer station more and more near residential block and people to the enhancing of environmental consciousness, the noise problem of transformer has been subject to the great attention of power department and transformer manufacturing factory.
Analyze from the vibrative reason of power transformer.The vibration of transformer is mainly caused by the vibration of transformer body (mainly unshakable in one's determination and winding) and cooling device, in the scope being less than 100HZ, and the mainly vibration that causes of cooling device.Transformer just in stable operation is primarily of the vibration caused that is unshakable in one's determination and winding.Transformer core just in stable operation and the vibration of winding are mainly from following reason: the first, and the magnetostriction of silicon steel sheet causes vibration unshakable in one's determination; The second, there is the electromagnetic attraction because leakage field produces between silicon steel sheet seam crossing and lamination, thus cause vibration unshakable in one's determination; 3rd, when electric current is by winding, between winding, between line cake, between wire turn, produces Dynamic Electromagnetic Force, cause the vibration of winding.
Transformer noise is due to iron core, and the vibration of winding and cooling device produces.Iron core, winding is referred to as the body of transformer, therefore, can say again, and transformer noise is because the body vibration of transformer and the air flowing of cooling device fan produce.
If Fig. 1 and 2 is transformer base structure in prior art, transformer comprises several iron cores arranged in parallel 1, understructure comprises two folders 2 and two pieces of insulation boards 3, each folder 2 all forms 23 in C character form structure by upper plate 21, intermediate plate 22 and lower plate, cored 1 both sides, front and back be all coated with insulation board 3, all fit and be provided with intermediate plate 22 in the outside of each insulation board 3, iron core 1, between insulation board 3 with folder 2 by with several iron cores one to one the first screw rod 4 be fixedly connected with; The downside of each lower plate 23 is all fixedly connected with a planchet plate 5, and planchet plate 5 is fixedly installed on feet backing plate 6, and feet backing plate 6 is fixedly installed with in feet 7.Feet 7 is provided with fan supporter 8, fan supporter 8 is fixed with blower fan 9.
Can find that above design is fixed on fan supporter 8 by blower fan 9, then fan supporter 8 is fixed in feet 7, when the impact that such design can produce is transformer operation, the vibration that the vibration of transformer body adds fan 9 can make whole transformer noise excessive, and in prior art, directly transformer is placed in ground, completely without any buffering, this also will cause the vibration & noise of transformer more violent.
Summary of the invention
The purpose of this utility model, a kind of transformer base structure that can alleviate transformer vibration is provided exactly in order to solve the problem, this understructure not only changes position in original technology on transformer base between each parts and annexation, but also add the parts of many dampings, the effect that good damping removes noise can be reached.
The purpose of this utility model is achieved in that
A kind of transformer base structure, described transformer comprises several iron cores arranged in parallel, described understructure comprises two folders and two pieces of insulation boards, described each folder is all made up of upper plate, intermediate plate and lower plate in C character form structure, the both sides, front and back of all described iron cores are all coated with described insulation board, all fit and be provided with intermediate plate in the outside of described each insulation board, described iron core, between insulation board with folder by with several iron cores described one to one the first screw rod be fixedly connected with;
The downside of described each lower plate is all fixedly connected with a planchet plate, and described planchet plate is fixedly installed on feet backing plate, and described understructure also comprises
The fan supporter be fixedly connected with the downside of described upper plate;
Be fixedly connected with described fan supporter and hang the blower fan arranged; And
Two to be symmetrically fixed on below described feet backing plate and feet;
The two ends of described each feet are respectively arranged with a damping device, are fixedly connected with silicagel pad below described each damping device.
Above-mentioned a kind of transformer base structure, wherein, described damping device comprises outer sleeve and to be arranged in described outer sleeve and can to carry out the inner sleeve of relative motion with described outer sleeve; Upper shed place of described inner sleeve is fixedly connected with upper top cover, and the lower opening of described outer sleeve is fixedly connected with lower bottom cover; Be provided with compressing tablet in described inner sleeve, described compressing tablet is fixedly connected with by the second screw rod with described upper top cover; Be provided with a spring in described outer sleeve and inner sleeve, upper end and the described compressing tablet of described spring are conflicted, and the lower end of described spring is connected with described lower bottom cover.
The beneficial effects of the utility model are as follows:
Compared with prior art, structurally maximum change of the present utility model changes blower fan into suspended structure exactly, because blower fan in prior art and feet are linked together by fan supporter, the vibration that blower fan produces can cause very large vibration, the utility model is by blower fan and feet isolation, and by fan supporter by blower fan and hang on folder, reduce the noise of transformer blower fan.Meanwhile, breakthroughly again in the utility model under feet, damping device and silicagel pad are installed, whole transformer and ground have been isolated, the vibration of whole transformer is dropped to minimum, greatly reduces noise.
