The acoustic board set (1) is connected with the fan operation observation part (2), the fan operation observation part (2) is then connected with the silencer body and fan flexible connection part (4), the silencer body and fan flexible connection part (4) is flexibly connected with a transformer fan (7), the whole transformer fan silencing device is erected on the sliding rail (3) on the ground through sliding wheels (8), and positioning clamps (9) for limiting the sliding wheels (8) are arranged on the sliding rail (3); the acoustic board set (1) is composed of one or more acoustic boards (5), and all the acoustic boards (5) are perpendicularly fixed to a silencer outer shell (6). By means of the transformer fan silencing device, influences of noise of the transformer fan on the ambient environment can be effectively reduced.
Description
Technical field
The utility model relates to transformer noise reduction process device, especially transformer fan silencers apparatus structure technical field.
Background technique
Along with development and the townie needs of electrical network, the electric substation of voltage levels and electric transmission line have started to enter into urban district in recent years.Beijing just starts to build the electric substation of 500kV in urban district in 2004.Development and expansion along with city, original 220kV and the 110kV electric substation building in suburb of Yunnan Power System, at it, the buildings such as house have been built gradually around, the noise problem being caused by the transformer of above-mentioned voltage levels has increasing trend, and electric substation's noise has been the problem that must face.
Through undergone mass production actual verification, find, operating transformer fan noise is one of main source of whole transformer noise.Fall low noise method, generally from sound source, propagation process and three aspects of acceptor, consider.Noise source in electric substation is mainly to derive from transformer, the electric substation in urban district has building and citizen zone of action around, its propagation length is very short, consider actual conditions, it is unpractical from acceptor (citizen), reducing noise, so research will be carried out noise reduction process from sound source (transformer) and propagation process.And for operating transformer, change fan possibility not high, and therefore, for transformer fan installs silencer additional, from propagation path, consider to carry out noise reduction process, be comparatively actual and economically viable.
Summary of the invention
The progress of society, the development of electrical network, voltage levels electric substation enters urban district, and the problem of being brought by transformer noise is increasing, and it is carried out to noise reduction process, unavoidable.From Noise Theory, sound wave can be worked as its crest and trough when superimposed in propagation process, can cancel out each other, and realizes " noise reduction "; Or sound wave can be absorbed by the material suitable with its frequency (wavelength).This use new device designs according to above-mentioned theory, can carry out noise reduction process targetedly for the transformer fan of different model.
The utility model is realized by following technical proposal.
A transformer fan silencer, the utility model is characterised in that:
1) transformer fan silencers is connected to form by acoustic board group, fan operation observation part, slide rail and muffler body and fan flexible joint part; Wherein: acoustic board group is observed part with fan operation and is connected, fan operation is observed part and is connected with fan flexible joint part with muffler body, and fan flexible joint part and transformer fan are flexible coupling; Whole transformer fan silencer is located on base track by pulley frame, and on slide rail, is provided with the location card of spacing pulley.
Whole device can be slided along transformer fan center line direction, normally move timer and fan is flexible coupling, when overhauling or needing, can outwards skid off along slide rail, not affect the normal operation with fan of carrying out of other work;
2) acoustic board group attracts plate to form by more than a slice (quantity is according to different model transformer mode of operation of fan calculative determination), and all acoustic boards are all vertically fixed on silencer casing.Gap between every acoustic board thickness, length, width and acoustic board, acoustic board apart from fan distance (partial-length is observed in fan operation) all according to different model transformer mode of operation of fan calculative determination.
The beneficial effects of the utility model are: can design according to different model transformer fan, select different sound absorbing materials, adopt pointed acoustic board group design, transformer fan is carried out to noise reduction process.
Below in conjunction with accompanying drawing and example, further set forth the utility model content.
Accompanying drawing explanation
Fig. 1 transformer fan silencer schematic diagram.
Embodiment
A transformer fan silencer, the utility model is characterised in that:
1) transformer fan silencers is connected to form by acoustic board group 1, fan operation observation part 2, slide rail 3 and muffler body and fan flexible joint part 4; Wherein: acoustic board group 1 is observed part 2 with fan operation and is connected, fan operation is observed part 2 and is connected with fan flexible joint part 4 with muffler body, and fan flexible joint part 4 is flexible coupling with transformer fan 7; Whole transformer fan silencer is set up on base track 3 by pulley 8, and on slide rail 3, is provided with the location card 9 of spacing pulley 8.
Whole device can be slided along transformer fan center line direction, normally move timer and fan is flexible coupling, when overhauling or needing, can outwards skid off along slide rail, not affect the normal operation with fan of carrying out of other work;
2) acoustic board group 1 attracts plate 5 to form by more than a slice (quantity is according to different model transformer mode of operation of fan calculative determination), and all acoustic boards 5 are all vertically fixed on silencer casing 6.Gap between every acoustic board 5 thickness, length, width and acoustic board 5, acoustic board apart from fan distance (part 2 length are observed in fan operation) all according to different model transformer mode of operation of fan calculative determination.
See Fig. 1, this figure has demonstrated transformer fan silencer schematic diagram.By diagram, can find out that this device is connected with whole silencer and is followed successively by muffler body and fan flexible joint part 4 from transformer fan, part 2 and muffler body are observed in fan operation, the acoustic board group 1 that acoustic board 5 forms is installed in muffler body, whole silencer is installed on slide rail 3, by pulley 8, slided, and can to it, be positioned by location card 9, do not affect the normal operation of transformer and fan, carrying out of maintenance and other work, can reduce noise 12-17dB left and right simultaneously, can effectively reduce the impact of transformer fan noise on surrounding enviroment.
