摘　　要：机上大感性负载和电源接触器在进行通/断电及工作模式转换过程中,电源汇流条上会产生电瞬变干扰信号,继而导致同一汇流条上其它设备的敏感。通过对商用客机电瞬变电磁兼容性机上验证方法的研究,给出了商用客机机载电瞬变干扰源和敏感设备的选取原则和方法,介绍了电瞬变电磁兼容性机上地面试验验证方法的实施流程,为CCAR/FAR-25部第25.1431(d)条款的试验验证提供了技术支持,并指导完成了我国自主研发的商用客机首次电瞬变电磁兼容性的测试。An electrical transient signal will be produced when the large inductive load or power bus contactor turn on/off or changing work mode, which will introduce susceptibility of the equipments on the same power bus. Through the study on the methods conducting ground test of electrical transient, this paper described the philosophy and methods of distinguishing the large inductive load and victims in the civil aviation, supplied the practical guidance for ground test of electrical transient test thereafter, experienced gained can be a reliable support to airworthiness CCAR/FAR-25.1431.d certification, and guiding the transient electromagnetic compatibility test completed on domestic civil aircraft.
