Description
technical field [0001] The invention relates to the field of rail transportation, in particular to a system for monitoring stray currents. Background technique [0002] In the existing stray current monitoring system in China, sensors are installed on both sides of the bottom of the system, that is, the driving section. The current sensors mainly measure: body potential, reference potential, and rail structure potential. Through the unit time operation of the system, the minimum polarization potential, negative average polarization potential, positive average polarization potential, maximum polarization potential, minimum orbital potential, negative average orbital potential, and positive average can be calculated through the monitoring device. The measured data of the rail structure potential and the maximum rail structure potential can only reflect the corrosion situation of each monitoring point, and cannot measure the actual leakage situation and specifically locate the ...
