Reduction of vibration noise for amorphous metal alloy core distribution transformer

Abstract

To understand the vibration noise behaviors of amorphous metal alloy core distribution transformer (AMACDT), a 10 kVA prototype was tested under no-load and short-circuit conditions, respectively.Uav Lipo Battery Pack 6s 5200mAh 22.2V Hrl8243143, and the primary side was connected with different load resistances. The largest amplitude positions on the upper bracket and tank surfaces were recorded by vibration sensors arranged on the surface. A data-acquisition platform was set up for signal measurement. The vibration amplitude related to frequency was discussed, and experimental results indicated that the position with the largest amplitude accrued in the middle of the upper bracket and tank surface, at phasesaandc, respectively.Hotsale 18PCS 3W LED Wall Washer Bar Waterproof Light. At the same time, some rib-reinforcements were welded on the upper bracket and tank surfaces to lessen the vibration energy, which reduced the noise.
