With the rapid development of the power grid and the increase of power demand, the voltage level of the substation is improving rapidly. The noise caused by the transformer becomes a serious problem because it affects the health of the surrounding residents. In this paper, the noise of 1000kV transformer in Shanxi is measured and analyzed. The results show that the transformer noise has low frequency...
In order to enhance the operation performance of middle-voltage vacuum circuit breaker, the single phase permanent magnet swing torque motor is presented according to the 40.5kV indoor vacuum circuit breaker. In the aspect of theoretical analysis, the motion characteristics and load characteristics of transmission system are studied and given the structure design and parameters of permanent magnet...
