The transformer is an amorphous alloy three-dimensional wound core transformer, the amorphous alloy material has the characteristic of high brittleness, and the vibration generated by the operation of the transformer can enable the amorphous alloy three-dimensional wound core to generate fragments and scraps. In the process of convection of the transformer oil in the transformer oil tank 200 due to heat dissipation, fragments and debris migrate and settle along with the transformer oil. The magnetic attraction piece 120 of the fragment adsorption device 100 can attract the fragments and the fragments, and the problems that the fragments and the fragments are migrated and settled to cause insulation faults of the transformer and influence the power supply reliability of the transformer are avoided.
The magnetic attraction piece 120 is affected by the high temperature of the transformer, and the magnetism can be weakened along with the time; the magnetic member 120 of the fragment adsorbing device 100 in this embodiment is disposed on the lower surface of the oil tank bottom plate 210 through the fixing member 110, that is, on the outer side of the transformer oil tank 200, so as to facilitate replacement of the magnetic member 120 with weakened magnetism.
The fixing member 110 and the magnetic member 120 located on the lower surface of the tank bottom plate 210 may fall out of the tank even if fragments are generated, and the fragments may not migrate with the transformer oil, such as the fixing member 110 and the magnetic member 120 disposed in the transformer tank 200.
In some embodiments of the present invention, the magnetic attraction member 120 is a permanent magnet. The permanent magnet refers to a magnet capable of maintaining its magnetism for a long period of time. The permanent magnet is a hard magnet, is not easy to lose magnetism due to the influence of high temperature of the transformer, is not easy to be magnetized, and has no change in polarity.
In some embodiments of the present invention, the magnetic attraction member 120 is a neodymium iron boron magnet or a ferrite magnet. The neodymium iron boron magnet or the ferrite magnet has strong heat resistance and is not easy to lose magnetism under the influence of high temperature of the transformer.
