摘　　要：配电变压器是配电网的关键装置,但其运行期间易受到短路电流的干扰,由此引发低压出口短路等故障,严重危害设备的稳定性,甚至诱发安全事故。对此,文章以400 kVA配电变压器为基本对象,围绕其出口短路故障展开分析,以供参考。Distribution transformer is the key device of distribution network,but it is easy to be disturbed by short-circuit current during its operation,which leads to low-voltage outlet shortcircuit and other faults,seriously endangers the stability of equipment,and even induces safety accidents.In this regard,this paper takes the 400 KVA distribution transformer as the basic object,analyzes its outlet short circuit fault for reference.
