PANTOGRAPH OF THE AUTOMATICALLY CONTROLLED SYSTEM FOR ELECTRIC ROLLING STOCK

The ER-200 d.c. electric train is being developed in the USSR, the operating speed being 200 km/h. A special pantograph was designed for this train to provide for a satisfactory and reliable current collection. The main task put before the designers of the pantograph consisted in the fact that the effective mass of it should not exceed 2.5 kg. sec/sec/m in case of current collection up to 1700 A and of the operating range of height of the contact wire equal to 1500 mm. This problem was solved by means of using automatic control. Unlike the widely spread symmetric (four- and two-armed) and asymmetric (single-armed) designs, an automatically controlled pantograph has two systems of movable frames--upper and lower ones. The upper system of movable frames is a pentahedron, the arms of which, however, unlike the arms belonging to serial Soviet designs, were shortened approximately two-fold. The lower system is made as two parallelograms, the upper horizontal sides of which are the base on which the rotatable shafts of the upper system are located. The fact that the given operating range of heights of the contact wire suspension does not influence the value of the pantograph effective mass (it influences only the length of the levers (arms) of the lower movable system) allow to consider that the use of the automatically controlled pantographs may be a solution of the problem of current collection.
