国产受电弓一直使用钢球式缓冲阀控制升降弓速度,该阀由于原理上的问题,作用不良、难于调整。法制6G型电力机车使用Faiveley式缓冲阀控制升降弓速度,该阀较前者有较大改进,但我们认为仍不甚理想。所以近年来。我们在研制新型升降弓阀的同时,对受电弓升降弓速度的控制问题进行了一些原理性的探讨。一、机车所要求的升降弓时间特性升降弓时间特性,是机车受电弓的重要特性之一。用户十分重视该特性的调整,制造广在出厂时也要仔细调整该特性,这是因为该特性的优劣会直接、间接地影响到机车
Domestic pantograph has been using ball-type buffer valve control bow speed, the valve due to the principle of the problem, the role of poor, difficult to adjust. The French 6G electric locomotive uses the Faiveley-type damping valve to control the speed of the raising and lowering bow. The valve has greatly improved over the former, but we think it is still not quite satisfactory. So in recent years. In the process of developing a new type of lifting bow valve, we carried out some theoretical discussions on the control of the bow speed of the pantograph. First, the required lifting of the locomotive time characteristics of the bow down time characteristics of the pantograph is one of the important characteristics of locomotives. The user attaches great importance to the adjustment of this feature, manufacturing wide factory carefully adjusted this feature, it is because the merits of this feature will directly and indirectly affect the locomotive
