摘　　要：接触网短路试验是牵引供电系统联调联试的重要内容之一,利用吸上电流比原理,在AT供电方式下,用"DaqShortCircuit"进行短路试验测试,并依据测试结果分析接触网故障点标定装置的正确程度,进而对其相关参数进行修正,提高测距精度。Catenary short circuit test is one of the traction power supply system of the FBI try. It based on the principle of neutral current ratios. In the mode of AT, with ＇DaqShortCircuit＇ making a short circuit test, and using whose result to analyze the correct degree of the fault locating equipment, and then amend its relevant parameters to improve the ranging accuracy.
