Description
Technical Field
The invention relates to the technical field of transformer oil tanks, in particular to a transformer oil tank with good noise reduction effect and a use method thereof.
Background
Audible noise generated by the transformer is caused by magnetostrictive deformation of the core and electromagnetic forces within the windings, the oil tank and the magnetic shield. The transformer noise has three sound sources, namely an iron core, a winding and a cooler, namely the sum of noise caused by no-load, load and a cooling system. The reason why the iron core generates noise is that the silicon steel sheet constituting the iron core undergoes a minute change, that is, magnetostriction, under the action of the alternating magnetic field, so that the iron core periodically vibrates with the change of the exciting frequency. The reason why the windings vibrate is that the current generates electromagnetic force in the windings, and the leakage magnetic field can also cause the structural member to vibrate. The electromagnetic force (and amplitude of vibration) is proportional to the square of the current, while the emitted acoustic power is proportional to the square of the amplitude of vibration. Thus, the emitted acoustic power has a clear relationship with the load current.
The noise reduction treatment of the existing transformer oil tank cannot realize the detection and positioning function of a vibration source, the limit and fixing function of the oil tank, the vibration buffering function of the oil tank and the sound insulation and heat dissipation function of the oil tank, so that the noise reduction effect of the existing transformer oil tank is poor.
