Background technology
Dry-type transformer is widely used in the place such as local lighting, skyscraper, airport, harbour CNC plant equipment, simply
Say that dry-type transformer just refers to the transformer that iron core and winding are not immersed in insulating oil.The type of cooling is divided into natural air cooling
(AN) and air is forced to cool down (AF).During natural air cooling, transformer can the long-term continuous operation under rated capacity.Forced air cooling
When, transformer output capacity can improve 50%.Suitable for interrupted running overload, or emergent accident running overload；Due to mistake
Load loss and impedance voltage amplification are larger during load, in non-economy running status, therefore should not be at continuous for a long time
Running overload.
Existing society is with the continuous progress of power equipment technology, dry-type transformer answering in the production, life of people
With more and more extensive, while the also control in terms of more and more higher, especially noise of the requirement to it, it is this it is proposed that a kind of dry
Become indirect noise reduction system.

Preferably, the inner surface wall of the silencer cover is provided with acoustic board structure.
Preferably, it is bolted to connection between the transformer supporting plate and transformer fixed plate.
Preferably, it is fixedly connected between the transformer case body and transformer yoke by fixed support block.
Preferably, the transformer beam is provided with three altogether, and three transformer beams are separately mounted to transformation
The lower section of device coil.
Compared with prior art, the beneficial effects of the utility model are：The utility model is scientific and reasonable for structure, safe to use
Convenient, dry excitation sound caused by the cored magnetostriction of transformer dominant noise source, fan operation noise and the housing resonance of becoming is made an uproar
Sound, by the calculating of the parameters such as the quality issue to transformer each several part, the rigidity of structure, it is determined that rational beam hardness and thickness
Spend size, form the noise reduction system of an entirety so that the dry noise that becomes effectively is suppressed, while in blower fan outer cup one disappear
Sound cover, effectively absorb noise caused by blower fan.
