Existing dry-type transformer case is much more general, and what consider is to prevent being strayed into and anti-electromagnetic radiation of foreign object (for example mouse etc.), to avoid to the damage of the transformer in the shell with to the pollution of surrounding environment.And noise pollution also be to surrounding environment pollute a kind of, society is strict day by day to various noise pollution standards, each electricity consumption department for transformer noise require corresponding more and more higher.How each transformer manufacturer is many studies noise reduction from changing and optimize the transformer internal structure, but considers to change transformer case and reduces noise pollution to surrounding environment.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of noise reduction shell of dry-type transformer is provided, its simple in structure, easy manufacturing realizes, reduce radiation and prevent under the prerequisite of the function that foreign object is strayed into not losing the conventional dry transformer, can effectively reduce dry-type transformer and propagate into noise in the surrounding environment.
The purpose of this utility model realizes by following proposal: the noise reduction shell of this dry type transformer, it is the hexahedron structure that connects to form by top cover, base plate, left plate, right plate, back side panel, front side board, described front side board is provided with door-plate, wherein, at least one adopts noise reducing plate in described left plate, right plate, back side panel, front side board, the door-plate.
Certainly, described left plate, right plate, back side panel, front side board, door-plate also can all adopt noise reducing plate.
For realizing the utility model better, described noise reducing plate comprises metal covering flaggy, porous material layer, porous epoxy glass fabric flaggy, described metal covering flaggy is positioned at the outside, porous epoxy glass fabric flaggy is fixed in metal covering flaggy inboard, and described porous material layer is filled between metal covering flaggy, the porous epoxy glass fabric flaggy.Described porous material layer can adopt spongy layer, mineral wool layer etc.; Described metal covering flaggy is surface stainless steel flaggy or aluminium alloy panel layer.
Described door-plate is a revolving door, and it is connected with front side board by hinge page or leaf or bearing pin; Perhaps described door-plate is the slide rail door, and it is connected with front side board by slide rail.
Described door-plate comprises left-hand door plate, right door-plate, and its left-hand door plate, right door-plate are connected with front side board by hinge page or leaf or bearing pin respectively; Perhaps described left-hand door plate, right door-plate are connected with front side board by slide rail respectively.
Described top cover, base plate are shutter or metal grill panel.
Operation principle of the present utility model is: by at least one adopts noise reducing plate to reduce noise pollution in described left plate, right plate, back side panel, front side board, door-plate.There is the hole of small in a large number connection the sound-absorbing porous material layer inside of described noise reducing plate, and sound wave can go deep into material layer inside along these holes, with material generation rubbing action acoustic energy is converted into heat energy.Because most acoustic energy transforms for heat energy, so dry-type transformer reduces naturally greatly by the noise that the noise reduction shell is delivered in the environment; Because the shell skin is the metal covering flaggy, be the good conductor of heat again, so just can be delivered to the heat energy that is transformed in the environment rapidly, thereby can realize reducing noise pollution well.
Compared with prior art, the utlity model has following advantage and beneficial effect: effectively reduce the noise that transformer is delivered to surrounding environment, also solved moist insulation distance problem down, reduce the metal shell volume effectively, and manufacture craft is simple, strong operability.
