METHOD OF CHECKING EQUALIZING CURRENT IN DOUBLE-TRACK SECTION OF AC TRACTION MAINS

摘要

FIELD: electrified railway transport. SUBSTANCE: proposed method is based on determining summary time interval at no traction load within preset time by recording time intervals during which ratio of track currents between buses of substations is in inverse proportion to ratio of their resistances. Route mean square value of equalizing current is calculated by formed time interval and current values of odd and even tracks. EFFECT: enhanced accuracy of measurement, simplified checking. 2 dwg
