Abstract
1. Способ определения сопротивления контактной и рельсовой сетей, заключающийся в измерениях на экспериментальном участке железной дороги значений напряжения между рельсом и «удаленной» землей, напряжения контактной сети на границах экспериментального участка и тягового тока, одновременном снятии показаний с измерительных приборов в момент прохождения электроподвижным составом поста секционирования в режиме тяги, отличающийся тем, что напряжение на рельсе принимается отличным от нуля и измеряется относительно «удаленной» земли.2. Способ по п. 1, отличающийся тем, что на полигоне переменного тока измерения значений напряжений и токов осуществляются с учетом фазового сдвига между ними и их учете при расчете сопротивления.1. A method for determining the resistance of the contact and rail networks, which consists in measuring the voltage between the rail and the “remote” earth on the experimental section of the railway, the voltage of the contact network at the boundaries of the experimental section and the traction current, while taking readings from the measuring instruments at the time the electric rolling gear passed section section in traction mode, characterized in that the voltage on the rail is taken to be different from zero and measured relative to the "remote" earth. The method according to claim 1, characterized in that at the alternating current polygon, voltage and current values are measured taking into account the phase shift between them and taking them into account when calculating the resistance.
