Abstract

Feeders are a standard installation of DC electrified railways in Japan in order to complement the electric capacity of contact wires. Recently in metropolitan area in Japan, the installed area of the feeder messenger catenary system that has the function of feeder in messenger has been expanded. Then we developed a new feeder messenger catenary system with the auxiliary wire that has the function in which the contact wire is hard to break. For this purpose, we investigated the best structure of this catenary system first and simulated electric performance. Then we performed running tests by using a pantograph installed on the current collection testing equipment of our institute and evaluated the current collecting performance of the new system. From the results of these tests, it has been proved that there are no problems in its current collectin
