Noise and vibration measurement and analysis of amorphous alloy transformer in semi-anechoic environment

In this paper, a transformer noise and vibration test platform which can simulate the actual operating conditions is built in a semi-anechoic chamber. A prototype of three-phase oil-immersed amorphous alloy distribution transformer with a rated capacity of 10kV/100kVa is taken as the test object. The effects of different no-load voltage, different three-phase balanced load, three-phase unbalanced load and harmonic load on noise and vibration of amorphous alloy distribution transformer are studied respectively.
