The invention provides a swing arm catenary system for a railway vehicle test bed. The system comprises a driving box, a supporting stand column, a swing arm and a transmission shaft, the driving box is fixed to the supporting stand column, one end of the transmission shaft is vertically embedded into the driving box, the other end of the transmission shaft vertically penetrates through the swing arm, a motor in the driving box drives the transmission shaft to deflect and further drives the swing arm to swing. According to the swing arm catenary system, the active mobile catenary is connected with the pantograph of the train on the railway vehicle test bed, and the connection points of the catenary and the pantograph are switched by continuously sliding in a reciprocating swing manner, and the potential safety hazards caused by local heating and too high local temperature rise to the pantograph and the catenary due to the fact that the current magnitude is influenced by the train power and cannot be limited and the contact point is not changed for a long time are further solved.

    一种轨道车辆试验台用摆臂式接触网系统,包括驱动箱、支撑立柱、摆臂、传动轴,其中,所述驱动箱固定于所述支撑立柱上,所述传动轴的一端垂直嵌入所述驱动箱中,另一端垂直穿过所述摆臂,通过所述驱动箱中的电机驱动所述传动轴发生偏转,并进一步带动所摆臂摆动。通过本发明所提出的一种摆臂式接触网系统,采用主动式的移动接触网与在轨道车辆试验台上的列车的受电弓进行连接,并以往复摆动的方式不断滑动切换接触网与受电弓的连接点,进一步解决因电流大小受列车功率影响而无法限制且接触点长时间不变化导致的局部发热及局部升温太高对受电弓及接触网的带来的安全隐患。
