摘要
针对汽车起重机中起重机子系统的电路系统中存在的传导性骚扰源,通过现场测试,指出了骚扰源的作用方式及其时域特性,比较了不同工况下、不同测试点的电磁骚扰特性,并通过分析得出影响骚扰源特性的因素主要是电磁骚扰电压中的不规则振荡部分。该分析结果为制定汽车起重机中起重机子系统专门的测试标准和进一步开展相关的电磁兼容研究提供了基础。
The conducted disturbance sources of the electrical system of the truck crane were investigated.The influence and the time-domain characteristics of possible conducted disturbance sources were analyzed.The electromagnetic disturbance characteristics at differenttestpointsunder different operation conditions were compared.Based on the analysis of test results,it was pointed out that the irregular oscillation was the main factor for the electromagnetic disturbance voltage.The presented results could provide a basis for the developmentofaspecialstandardfortheEMCtestofthetruckcraneandfurtherrelevantEMCresearch.
