Comparative review of the current collection quality parameters between catenary and pantograph by measuring the contact force and arcs simultaneously during new Korean high speed train trial runs

초록

This paper concerns the experimental comparison between contact force and percentage of arcing on the measurements of the current collection quality between catenary and pantograph. According to the UIC 799 and EN50119, a good current collection quality is defined in a contact force(F) method (index) as Fmin-3σ > 0N. Meanwhile, according to the IEC62486, in addition to the contact force method, a good current collection quality is defined also in a percentage of arcing(NQ) index as NQ ≤ 0.2%. In these various criteria for evaluating the current collection quality, we have been interested in the correlation between the contact force and the percentage of arcing. We have a chance to measure the current collection quality during new train(HEMU-430X) test runs. We installed the contact force measuring device and also the arc detecting one simultaneously for the same HEMU-430X pantograph. We made measurements and obtained the data from the both devices. In this paper, the measurement works and result data of the contact force and the percentage of arcing are described. Furthermore, the result data are comparatively reviewed in the viewpoint of the international standard criterion for the both parameters.
