DESIGN OF THE CURRENT LOGGER OF AUTOMATIC CONTROL SYSTEM FOR CURRENT COLLECTORS WITH ICE OR RIME FROST ON THE OVERHEAD LINE

Branislav Gavrilović, Zoran Bundalo

The article considers the ways of regulation of pantographs to provide quality and reliability of current collection. To assess impact of regulation was proposed integral criterion of the quality of current collection, taking into account efficiency and reliability of operation of the pantograph. To monitor the contact strip it is possible to utilise the fact that arcing between the contact strip and the overhead line generates a DC component in the AC locomotive current. The paper presents a automatic control system to regulate contact force between pantograph and contact wire with respect to conditions of the interaction process. The wear of the contact strip is predicted by monitoring the running distance of the pantograph as well as the DC component of the AC locomotive current. The experimental results show that the use automatic control system in design of pantographs can improve the quality and reliability of the current collection with ice or rime frost on the overhead line. Using movement DC component of the locomotive current (Ikc) as input signal for control system can be almost as effective as using direct contact force measurement.
