Preferably, described hang spring-loaded quantity for four.
Preferably, the quantity of the spring shock absorption part is four.
Employ after above-mentioned technical proposal, the beneficial effects of the utility model are：
Because upper clamping piece is connected with lifting spring, lower clamping piece is connected with spring shock absorption part, therefore when transformer body work
When, the vibrations that transformer body is produced obtain lifting effective buffering of spring and spring shock absorption part, reduce because of transformer body production
Influence of the raw vibrations to protection shell, effectively reduces noise.
Because the top plate for protecting shell is surrounded by upper venthole, the bottom plate of protection shell is surrounded by lower air admission hole, on
Venthole and lower air admission hole formation cross-ventilation, enhance the radiating effect of transformer.
Suction fan is additionally provided with top plate due to protecting shell, suction fan will protect the air in shell to be drawn onto outside,
Accelerate the air flow in protection shell.
Due to being provided with the second damping spring between low-voltage coil group and high-tension coil group, it is possible to reduce what core assemblies were produced
Vibrations.
In summary, a kind of damping noise reduction dry-type transformer of the utility model solves transformer in the prior art and worked
When, can be because vibrations produce resonance with protection shell, the problem of causing very big noise.A kind of damping noise reduction of the utility model is done
Formula transformer, can eliminating transformer when using vibrations to protecting the influence of shell, the noise that reduction transformer is produced.
