Rectifier life and influence range analysis system to secure the stability of urban gas piping

摘要

The present invention accurately predicts the remaining life of each rectifier by measuring and analyzing the voltage and current values of the rectifier that supplies the corrosion protection current to the underground city gas pipe and the corrosion potential potential for each section of the city gas pipe, It relates to a rectifier analysis system that derives a range value that a rectifier affects on a city gas pipe so that it can be used for city gas pipe management. The rectifier lifetime and impact range analysis system for securing the stability of city gas pipelines according to the present invention is installed one by one in a plurality of rectifiers that supply corrosion protection current to city gas pipelines buried underground to measure the voltage and current values of each rectifier. A plurality of voltage and current measuring units that transmit the measured voltage and current values to the outside, installed spaced apart from each other so that the corrosion potential of the underground city gas pipeline can be measured separately for each section, and measured in each section A plurality of protection potential measuring units that transmit the protection potential of the rectifier to the outside, an output adjusting unit capable of remotely adjusting the output of each rectifier, and voltage and current values transmitted from a plurality of voltage and current measurement units and a plurality of protection potential measurement units And by receiving and analyzing the corrosion protection potential value, characterized in that it comprises an analysis unit for deriving a range value that affects the remaining life of each rectifier and city gas pipe.
