摘　　要：铁道牵引变电所接线复杂且负荷三相不对称,给牵引供电线路带负荷试验带来困难。根据平衡变压器接线特点以及牵引变电所换相联结情况,提出牵引供电线路带负荷试验新思路,并通过案例加以验证,试验结果正确。The connection mode of railway traction substation is complex and shows the load three-phase asymmetry,which brings about difficulties to the load tests of traction power supply lines.Based on the connection characteristics of balance transformer and the connection of traction substation in phase commutation,a new idea on load tests of traction power supply lines is proposed,which is verified in cases with accurate outcomes.

关 键 词：带负荷试验 平衡变压器 换相联结 牵引变电所
