Electric traction hang modulo null under low-altitude head facility

摘要

PURPOSE: To stabilize a pantograph as a simple catenary overhead cable using a simple configuration and achieve speed-up of electric cars. ;CONSTITUTION: A catenary electric car cable of overhead single-line type is so structured that the overhead cables 6 on both sides of a low head clearance facility structure 1 are connected with two aux. trolley lines 9 through two-gang yokes 8. The main trolley line 4 is hung by a special hanging tool till near the structure 1 by the aux. trolley lines 9, and the main line and aux. lines are set over parallel under the structure. Because the three lines are set parallel under the structure, the pantograph is made stable, and it is also possible to feed electricity from aux. troley lines connected with the overhead cable, and electric cars can run at a high speed without deceleration even under any low head clearance facility structure.;COPYRIGHT: (C)1994,JPO&Japio
