Abstract
The utility model relates to a vibration absorptive structure of an amorphous alloy iron core power transformer. An elastic body cushion block A is welded between a suspension board and a transformer body, the suspension board is disposed between two sides of a case cover of the transformer, the suspension board, the elastic body cushion block A and the transformer body are fixedly connected with each other through a pin shaft, and clearances of 2 mm remains among the suspension board, the elastic body cushion block A and the transformer body, an elastic body cushion block B is disposed between the lower portion of the transformer body and a bottom plate of a case bottom, a comparatively thick elastic body flat block is disposed on the upper portion of the elastic body cushion block B, a plurality of elastic body cylindrical convex blocks are arranged below the elastic body flat block, the overall elastic body cushion block B is formed by one-time mould pressing of the elastic flat block and a plurality of elastic body cylindrical convex blocks, both the elastic body cushion block A and the elastic body cushion block B are made of cork rubber plate blocks, and a cork rubber plate block can be any one of a butadiene-acrylonitrile rubber plate block, a chloronorgutta plate block or a butylbenzene rubber plate block. The vibration absorptive structure of an amorphous alloy iron core power transformer is simple in structure, convenient in installation, reliable in operation and capable of greatly decreasing out-spreading of noise during operation of the transformer, thereby enormously decreasing noise pollution of the environment around the transformer.
Description
Technical field
The utility model relates to a kind of shock-damping structure of amorphous alloy iron core electric transformer.
Background technology
Use the hard method of placing that connects when at present, the amorphous alloy iron core electric transformer that generally uses on the market is placed in the casing.Both sides welding two boatswain chairs 2, these boatswain chairs 2 directly are connected with transformer body 4 by bolt 3 on the case lid 1 of transformer top.Lay polylith hard packing piece 5 at the bottom of transformer body 4 bottoms and the case between the base plate 6.The noise that produces because of magnetostrictive effect when this structure makes the transformer operation directly passes to the casing outside by the vibrations of hard coupling components, causes the great noise pollution of transformer surrounding environment.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy for installation, reliable and can greatly reduce the shock-damping structure of the amorphous alloy iron core electric transformer of transformer when operation noise unofficial biography, and this shock-damping structure can greatly reduce the noise pollution of transformer surrounding environment.
The technical solution of the utility model is: a kind of shock-damping structure of amorphous alloy iron core electric transformer, and it is respectively to weld a boatswain chair in the middle of transformer case lid both sides, this boatswain chair links by bearing pin and transformer body.Lay the polylith cushion block at the bottom of transformer body bottom and the case between the base plate.Be characterized in: elastomer cushion block A of pad between boatswain chair in the middle of the transformer case lid both sides and the transformer body, bearing pin is fixed together boatswain chair, elastomer cushion block A and transformer body, and the gap of 2mm is left in the centre.The polylith cushion block of laying between the base plate at the bottom of transformer body bottom and the case is elastomer cushion block B.This elastomer cushion block B is that top is the dull and stereotyped piece of a thicker elastomer, a plurality of elastomer cylindrical bumps is arranged below the dull and stereotyped piece of elastomer.The dull and stereotyped piece of elastomer and a plurality of elastomer cylindrical bump are the whole shape elastomer cushion block B that disposable mold pressing is made.
Described elastomer cushion block A and elastomer cushion block B all select the cork-rubber plate for use.
Described cork-rubber plate is selected any in acrylonitrile-butadiene rubber plate, neoprene plate or the butadiene-styrene rubber plate for use.
Described cork-rubber plate is the off-the-shelf of professional production enterprise processing and fabricating.
Performance characteristics of the present utility model is: adopt scientific formula production by what cork-rubber plate, the advantage that integrates cork and rubber, both keep ageing-resistant, oil resistant, temperature tolerance, great friction coefficient, the good compression of cork and compressed restoratively, had the high resiliency of used rubber and the tensile strength of share again.Performances such as media-resistant are similar to the rubber properties of selecting for use, oil resistance is better.All select above-mentioned cork-rubber plate for use by what elastomer cushion block A and elastomer cushion block B, the noise that produces because of magnetostrictive effect when this moves with regard to making transformer can not or can not pass to the casing outside by the vibrations of above-mentioned cork-rubber plate substantially, and this just makes the transformer surrounding environment be improved greatly.
The utility model has the advantages that provides a kind of simple in structure, easy for installation, reliable and can greatly reduce the shock-damping structure of the amorphous alloy iron core electric transformer of transformer when operation noise unofficial biography, and this shock-damping structure can greatly reduce the noise pollution of transformer surrounding environment.
