摘要: According to the comparison of the simulation results of 3 D FEM and 2 D axisymmetric FEM to calculate the short-circuit force of the transformer, the maximum force of the transformer is analysed. It is found that 3 D FEM is more accurate in calculating short-circuit force....
53 sets 110-220 KV transformers from 44 enterprises (No. 30 - 60 kV system in northeast network is the same class as 110kV in other part of China) passed short-circuit test. The rate of qualified 110kV transformers was approximate 100% (in the first time). If Transformer Works need to...
