고속전철용 집전장치 동특성 및 집전성능 계측시스템 개발

초록

In this paper, we introduce the measuring system which was developed in order to measure the dynamic characteristics and evaluate the current collection performance of proto-type Pantograph on Korean High Speed Train. The measuring system has two obvious peculiarities, the first one is that the signal processing amplifiers of each sensors were sufficiently insulated and tuned to same impedance level to protect from electro-magnetic interference caused by high voltage and current of 25kV AC, and the other point is that the measuring system has adopted wire-less telemetry technology in transmitting & receiving of measured data to prevent occurring short circuit through the data communicating cables.
