Schematic Implementation of an Analog Traction-Current Asymmetry Alarm

It is proposed to implement an analog traction-current asymmetry alarm integrated into existing systems of technical diagnostics and monitoring of railway automation and telemechanics. Two circuit solutions of the block of nonlinear signaling operations have been developed. An analysis was carried out of the operation of an analog signaling device in the Micro-Cap computer simulation package, which showed the dependence of the characteristics of the diodes on the temperature in the proposed scheme, which significantly affects the operation of the device. To eliminate the identified shortcomings, it is necessary to supplement the developed alarm with a thermal compensation module at the next stage.
