Abstract:

Aiming at the problem that the leakage of stray current has great corrosion and damage to the equipment and main structure, and the function of the conventional detection technology is single, an integrated comprehensive monitoring and analysis system integrating the conduction cabinet, the drainage cabinet and the rail potential limiting device is proposed. By analyzing the relationship between the rail potential and the stray current, and intelligently designing the conduction cabinet, the drainage cabinet, and the rail potential limiting device, intelligent drainage can be performed. The system includes a reference electrode, a collector, a monitoring device, a drainage cabinet, a one-way communication device, a background of the main station, and the like. According to the full-line stray current control index, combined with the state of different equipment and its coupling with the stray current system, the multi-parameters are analyzed and calculated, and the intelligent conduction cabinet, drainage cabinet, and rail potential limiting device are optimally integrated. Control methods to achieve optimal stray current management. The tests show that the scheme designed in this paper minimizes the corrosion and damage to the equipment and main structure caused by the leakage of stray current, and prolongs the service life of equipment and rail hole structure.
