Abstract
The utility model provides a low-noise amorphous alloy transformer, which comprises a fuel tank cover (1), a fuel tank body (2), a connecting screw bolt (3) for connecting the transformer body and the fuel tank cap, a nitrile rubber washer (4), an upper clamping piece hanging plate (5), a lock nut (6), an upper clamping piece (7), an amorphous alloy iron core (8), a coil (9), a lower clamping piece (10), a nitrile rubber plate (11) and a fuel tank bottom plate (12). The nitrile rubber plate (11) is additionally arranged on a contract surface of a foot pad position of the lower clamping piece (10) of the transformer body and the fuel tank bottom plate (12) to absorb shock, simultaneously, the rubber washer (4) is additionally arranged on the bolt connection position of the upper clamping piece (7) of the transformer body and the cover (1), thereby buffering direct contact of the transformer body and the fuel tank. For buffer action of the nitrile rubber washer and the nitrile rubber plate, the utility model largely reduces shock noise, and the noise decreasing amplitude is about 3-4 dB. The utility model has the advantages of being capable of reducing shock noise when operating the amorphous alloy transformer, enables whole noise of the transformer to meet noise requirements of the national standard, and is simple in method and obvious in effect.
Description
Technical field
The utility model relates to a kind of power transformer, relates in particular to a kind of amorphous alloy transformer that can reduce vibrations reduction noise.
Background technology
Non-crystaline amorphous metal is a kind of new material, international energy is deployed on calendar year 2001 and classifies amorphous alloy transformer as energy-conservation distribution transformer first-selected kind, amorphous alloy transformer no-load loss reduces by 75% than S9 type transformer, therefore, the extensive use of China's amorphous alloy transformer has brought a series of societies and economic benefits such as energy-conservation and environmental protection.But existing amorphous alloy transformer also has defective.Amorphous alloy transformer iron core is rolled by non-crystaline amorphous metal master tape material and forms, and adopts the square-section, three-phase four frame pentastyle structures.Amorphous alloy transformer is to be supported as the device body by coil and folder, and amorphous core is suspended on the coil.Because it shakes and has correspondingly just increased when operation for unshakable in one's determination suspension the, amorphous alloy transformer.In addition, transformer body adopts the transformer lower clamping piece and directly contacts by locating pin is fixing at the bottom of the fuel tank with the binding of fuel tank, and upper clamping piece directly is connected and fixed by bolt and cover plate.This iron has produced very big noise with contacting when shaking of iron, makes the overall noise of transformer increase.
The utility model content
The technical problems to be solved in the utility model is: at the above-mentioned defective of amorphous alloy transformer existence, the utility model provides a kind of low noise amorphous alloy transformer, the noise that produces because of vibrations in the time of effectively reducing the transformer body operation, thereby reduce the overall noise of transformer, make it be lower than the noise requirements of GB.
For solving the problems of the technologies described above, the scheme that the utility model proposes is: a kind of amorphous alloy transformer is characterized in that: it comprises connection screw rod (3), nitrile rubber packing ring (4), upper clamping piece boatswain chair (5), stop nut (6), upper clamping piece (7), amorphous alloy core (8), coil (9), lower clamping piece (10), nitrile rubber plate (11), the fuel tank base plate (12) of fuel tank cap (1), oil box (2), device body and case lid.
Come damping at transformer body lower clamping piece (10) pad pin place and fuel tank base plate (12) contact-making surface place increase nitrile rubber plate (4); The bolted on connection place of folder (7) and cover plate (1) increase rubber washer (11) comes damping on one's body device simultaneously, cushioning transformer body with this contacts with the direct of fuel tank, because the cushioning effect of butyronitrile rubber packing ring and butyronitrile rubber plate can make the vibrations noise significantly reduce the about 3～4dB of the noise range of decrease.
The beneficial effect of this utility model is: the vibrations noise in the time of can reducing the amorphous alloy transformer operation, thus the overall noise of reduction transformer make its noise requirements that is lower than GB, and this method is simple, and effect is obvious.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
In Fig. 1, amorphous alloy core (8) is suspended on by on the firm coil (9) of upper clamping piece (7) and lower clamping piece (10), and this part can produce vibrations owing to the effect of electromagnetic force when amorphous alloy transformer move.These vibrations upwards can and connect screw rod (3) by upper clamping piece boatswain chair (5), stop nut (6) and conduct on fuel tank cap (1) and the oil box (2), can conduct on the oil box (2) by lower clamping piece (10) and fuel tank base plate (12) downwards, lower clamping piece (10) produces noise with the high frequency bump and the oil box (2) by a narrow margin of fuel tank base plate (12) with extraneous contact-making surface high frequency bump by a narrow margin in the conductive process of vibrations.And between stop nut (6) and boatswain chair (5), add butyronitrile rubber packing ring (4), and after lower clamping piece (10) and fuel tank base plate (12) add butyronitrile rubber plate (11), because the cushioning effect of butyronitrile rubber packing ring (4) and butyronitrile rubber plate (11), can make the vibrations noise significantly reduce the noise range of decrease 3～4dB.
Claims (2)
1, a kind of low noise amorphous alloy transformer, it is made up of connection screw rod (3), nitrile rubber packing ring (4), upper clamping piece boatswain chair (5), stop nut (6), upper clamping piece (7), amorphous alloy core (8), coil (9), lower clamping piece (10), nitrile rubber plate (11), the fuel tank base plate (12) of fuel tank cap (1), oil box (2), device body and case lid, it is characterized in that: come damping at transformer body lower clamping piece (10) pad pin place and fuel tank base plate (12) contact-making surface place increase nitrile rubber plate (4).
