Abstract
The invention discloses a vibration damping and noise reducing dry type transformer, which comprises a main body, an iron core and a clamping fastening piece, wherein a vibration damping pad is arranged between the iron core and the clamping fastening piece. The vibration damping and noise reducing dry type transformer has the advantages that: a vibration damping part with reasonable material and structure is arranged between solid installations which are contacted with the iron core of the dry type transformer, and an inner structure of the iron core is bound through a strip, so that the dry type transformer keeps the original performance and can reduce vibration and transmission noise, the performance of the dry type transformer is improved, the noise pollution of an equipment operating environment is reduced, and the dry type transformer is particularly suitable for occasions having special requirements on noise or installation conditions.
Description
Technical field
The present invention relates to a kind of dry-type transformer, particularly a kind of dry-type transformer that can reduce vibration, reduce rotational noise.
Background technology
The vibration of dry-type transformer when operation not only can produce noise by the erecting device transmission, and long-time running also can produce certain influence to the performance of dry-type transformer.When the eigentone of dry-type transformer itself is identical with power frequency, covibration will take place, influence more obviously, and the noise of the vibration of the bigger dry-type transformer of capacity and generation thereof is particularly outstanding.
Dry-type transformer mainly is made up of the transformer body that comprises coil, iron core and clamping securing member, and iron core is main vibration source, and the transfer of vibration between it and the clamping securing member is to cause the main cause of the problems referred to above.
Summary of the invention
Goal of the invention:, the purpose of this invention is to provide a kind of dry-type transformer that can reduce vibration, reduce rotational noise at the problems referred to above.
Technical scheme: a kind of vibration and noise reducing dry-type transformer, comprise main body, iron core and clamping securing member, between described iron core and the described clamping securing member beam is installed.
For iron core is also reduced as far as possible in the vibration of vertical direction, described iron core also is equipped with cushion socket in a side relative with the lower margin support.
The material of described beam and described cushion socket is an elasticity absorbing material, can slow down the core vibration noise, reduces the transmission of vibration noise on folder and strutting piece.
Best, the material of described beam and described cushion socket is a silicon-based rubber.
Because iron core is to be layering by the coremaking material to make, iron core column and the band colligation of iron yoke to described core interior can reduce the issuable vibration of core interior structure.
Described beam and described cushion socket are the modularization molded part, carry out the modularized design moulding according to the transformer of different capabilities, install with assembling and improve.
Because cushion socket is installed on described iron core and is supporting a relative side with lower margin, bearing quite a few weight of whole transformer, therefore described cushion socket is a composite construction, the centre is a hard plate material, described hard plate material is up and down an elasticity absorbing material, support firmly, improve the effect of vibration and noise reducing.
Beneficial effect: compared with prior art, advantage of the present invention is by to mounting material between the solid installation material that contacts with dry-type transformer iron core, damping means rational in infrastructure, and to the colligation of core interior structure band, make dry-type transformer on the basis that keeps original performance, more can reduce vibration, reduce rotational noise, improved the performance of dry-type transformer, simultaneously the noise pollution of conditions for equipment use is improved, be specially adapted to noise or mounting condition are had the field of employment of specific (special) requirements.
Description of drawings
Fig. 1 is the structural representation of a kind of vibration and noise reducing dry-type transformer of the present invention;
Fig. 2 is the structural representation of cushion socket cross section;
Fig. 3 is the iron core column of core interior and the structural representation of iron yoke colligation.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment only is used to the present invention is described and is not used in and limit the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
Shown in accompanying drawing 1 to 3, a kind of vibration and noise reducing dry-type transformer comprises main body 1, iron core 2 and clamping securing member 3, between described iron core 2 and the described clamping securing member 3 beam 4 is installed.
Described iron core 2 also is equipped with cushion socket 6 supporting 5 relative sides with lower margin.Described beam 4 and described cushion socket 6 are the modularization molded part, and material is an elasticity absorbing material, particularly silicon-based rubber, can effectively reduce and absorb the vibration noise of iron core, prevent to vibrate the noise transfer that causes by the installing component propagation that is in contact with it.
The iron core column 7 and iron yoke 8 usefulness of described iron core 2 inside are with 9 colligations, reduce the issuable vibration of core interior structure.
Because cushion socket 6 is installed on described iron core 2 and is supporting 5 relative sides with lower margin, bearing quite a few weight of whole transformer, for this adopts composite construction to described cushion socket 6, the centre is a hard plate material 10, and described hard plate material 10 is up and down an elasticity absorbing material.
Through dispatching from the factory end product quality of the present invention is detected, detection noise reduces by 30%～50% than international standard, is specially adapted to noise or mounting condition are had the field of employment of specific (special) requirements.
