针对HXD3型机车投入运用以来发生的几起“辅接地”故障,从电路构成角度,给出了故障点的查找方法,为解决此类惯性问题提供参考。
Aiming at the several “auxiliary ground fault” occurred since the HXD3 locomotive was put into operation, the method to search for the fault point is given from the angle of the circuit structure, so as to provide references for solving such inertial problems.
