摘　　要：利用对称分量法，推导了三绕组Δ／Δ／Δ连接分裂变压器，在相间短路情况下的稳态短路电流和突发短路电流计算公式；在此基础上，利用有限元法，对变压器在相间短路情况下的漏磁场进行了计算和分析。By using the method of symmetric components,the paper derives a formula for calculating the steady and transient short circuit current.Further more,the leakage of magnetic field during the short circuit between phases as also calculated and analysed.
