Abstract
The utility model discloses a low -noise transformer belongs to the substation equipment field, including the box, the box both sides are equipped with a plurality of radiators, and the radiator passes through pipe and the inside intercommunication of box, and the radiator includes the metal casing, and the metal casing leaves with the box mutually, is equipped with damping pad and insulating layer between metal casing and box, and the damping pad touches with the box mutually, and the insulating layer touches with the metal casing mutually, the bottom half is equipped with the hydraulic stem, and it is fixed with outside object that the box passes through the hydraulic stem, the box surface covering has one deck noise damping layer, through increase damping or amortization part in many places, wholly reduces the noise that the transformer produced.
Description
Technical field
The utility model relates to converting equipment field, particularly a kind of low noise level transformer.
Background technology
Along with the development of urbanization process, land resource is in short supply, and a large amount of transformer is applied to the place of the people such as commercial center, office block, residential quarters work, life, then frequently causes noise and to exceed standard complaint.Therefore, noise when how control transformer runs, has become the focal issue that state's wet end door is paid close attention to.
Vibration is the root that noise produces, and transformer noise is produced by the magnetostriction of iron core, and outwards propagated by coupled object.One is the feet between transformer body and fuel tank, and two is the insulating oils between device body and fuel tank.In prior art, for the noise reduction technology of iron core, effect is general, and therefore the outside propagation of blocking transformer iron coring vibration and noise just becomes particularly important.
Prior art, the Chinese patent, the application number that are 201220447315 as application number are the Chinese patent etc. of 201320356540, although disclose the mode reducing transformer noise, are not suitable for oil-filled transformer or noise reduction is lower.
Summary of the invention
The object that the utility model will reach is to provide a kind of low noise level transformer, effectively reduces the noise produced when transformer runs.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of low noise level transformer, comprise casing, casing both sides are provided with some radiators, and radiator is communicated with box house by conduit, and radiator comprises metal shell, metal shell and casing from, be provided with beam and thermal insulation layer between metal shell and casing, beam and casing touch, and thermal insulation layer and metal shell touch; Bottom half is provided with hydraulic stem, and casing is fixed by hydraulic stem and exterior object; Tank surface is coated with one deck noise reduction layer.
Cause the casing of transformer to vibrate after iron coring vibration, and then cause radiator to vibrate.For the problems referred to above, cushion blocking is set between the metal shell and casing of radiator, effectively can weakens radiator and vibrate the noise sent, improve the stability of radiator simultaneously, extend the bulk life time of transformer; Between cushion blocking and metal shell, arrange thermal insulation layer, the shell that can effectively prevent the heat conduction of radiator from returning transformer-cabinet increases radiating efficiency; Hydraulic stem is set at bottom half and exterior object, can changes into being rigidly connected and flexibly connect, reduce the vibration of transformer whole further, effectively can absorb casing simultaneously after tank surface covers noise reduction layer and vibrate the noise sent.
Further, described transformer is threephase oil immersed transformer, and this structure is more suitable for threephase oil immersed transformer.
Further, described cushion blocking is rubber blanket, thus provides sufficient damping capacity, and with low cost.
Further, described thermal insulation layer is asbestos layer, good heat-insulation effect.
Further, described noise reduction strata ester acoustical cotton layer, effectively absorb vibration, cost is lower.
After adopting technique scheme, the utility model tool has the following advantages:
By increasing vibration damping or sound attenuation features in many places, the overall noise reducing transformer and produce.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the vertical view of a kind of embodiment of the utility model.
Fig. 2 is the front view of Fig. 1 embodiment.
Embodiment
Accompanying drawing 1-2 is depicted as a kind of embodiment of the present utility model.
A kind of low noise level transformer, for threephase oil immersed transformer, comprise casing 1, casing 1 both sides are provided with some radiators 2, radiator 2 is communicated with casing 1 inside by conduit 3, radiator 2 comprises metal shell 4, metal shell 4 and casing 1 from, be provided with cushion blocking 5 and thermal insulation layer 6 between metal shell 4 and casing 1, cushion blocking 5 and casing 1 touch, thermal insulation layer 6 and metal shell 4 touch, cushion blocking 5 is rubber blanket, thus provides sufficient damping capacity, and with low cost, thermal insulation layer 6 is asbestos layer, good heat-insulation effect; Be provided with hydraulic stem 7 bottom casing 1, casing 1 is fixed by hydraulic stem 7 and exterior object, reduces the vibration of transformer whole further; Casing 1 surface coverage has one deck noise reduction layer 8, and noise reduction layer 8 is polyester acoustical cotton layer, effectively absorb casing and vibrate the noise sent, and cost is lower.
Cause the casing 1 of transformer to vibrate after iron coring vibration, and then cause radiator 2 to vibrate.For the problems referred to above, cushion blocking 5 is set between the metal shell 4 and casing 1 of radiator 2, effectively can weakens radiator 2 and vibrate the noise sent, improve the stability of radiator 2 simultaneously, extend the bulk life time of transformer; Thermal insulation layer 6 is set between cushion blocking 5 and metal shell 4, can effectively prevents the heat conduction of radiator 2 from returning the shell of transformer-cabinet 1, increase radiating efficiency; Arrange hydraulic stem at bottom half and exterior object, can change into flexibly connect being rigidly connected, reduce the vibration of transformer whole further, effectively can absorb casing 1 after casing 1 surface coverage noise reduction layer 8 vibrates the noise sent simultaneously.
Except above preferred embodiment, the utility model also has other execution mode, those skilled in the art can make various change and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all should belong to the scope that the utility model claims define.
