The invention discloses a stray current monitoring device for a steel oil gas pipeline. The stray current monitoring device comprises an optical fiber current sensor, a switching module, a communication optical fiber, a collection unit, a collection communication terminal and a power supply management module, wherein the steel oil gas pipeline is wound with the optical fiber current sensor, the switching module, the communication optical fiber, the collection unit, the collection communication terminal and the power supply management module are sequentially connected, and the optical fiber current sensor is connected with the switching module; a background server is in communication connection with the collection communication terminal; the connection unit is connected with the power supply management module; and a solar cell panel and a storage battery are connected to the power supply management module. According to the stray current monitoring device, the current running in a steelpipeline can be monitored in real time, and the severity degree of the pipeline interfered by the stray current can be judged according to the size and direction of the current.
Description
technical field [0001] The invention belongs to the field of oil and gas pipeline monitoring equipment, in particular to a steel oil and gas pipeline stray current monitoring device. Background technique [0002] Steel oil and gas pipelines will be severely corroded under the influence of external stray currents. External stray current interference is a dynamic interference, which is a process that changes with time. The existing stray current equipment cannot monitor the current in real time, and the accuracy of detection is reduced, which cannot meet the requirements of research and production. Since the stray current flowing into the steel pipeline cannot be measured in real time, the degree to which oil and gas pipelines are affected by stray current has always been a difficult problem for scholars to study. Contents of the invention [0003] The object of the present invention is to provide a steel oil and gas pipeline stray current monitoring device, which can moni...
