Background
Buried metal pipelines are widely used for the transportation of petroleum, natural gas, water and the like. In order to slow down the corrosion of the pipeline and prolong the service life of the pipeline, a cathode protection system is installed on most long-distance pipelines. The gas transmission station which does not need protection is arranged along the long-distance gas transmission pipeline, and in order to prevent the leakage of cathodic protection current and the interference corrosion between the pipeline sections, electric insulation measures are adopted between the pipeline and equipment devices and the grounding grid, and between the pipeline sections. The insulating device is used for blocking the cathodic protection current on the pipeline from flowing into other non-protected metal equipment or structures connected with the cathodic protection current, and blocking the stray current of the interfered pipeline section from flowing into other pipeline sections. The insulated joints may be damaged, have reduced insulating properties, etc. due to factors such as materials, installation, structure, lightning strikes, aging, etc. The non-protection side is electrified to cause damage to personnel and equipment on the non-protection side, and meanwhile, the non-protection side shunts the negative protection current on the protection side, so that the protection side cannot be completely protected by the negative protection current.
At present, a PCM method, a potential method, an insulation resistance method and the like are adopted as a test method of an insulation joint, most of the test methods are mobile detection equipment, and only manual periodic detection can be carried out. Some patents also mention the adoption of automatic monitoring devices, but the adopted method is single, an external power supply is also needed, GPRS is adopted for remote data transmission, the speed is low, data is easy to lose, and whether an insulated joint is damaged or not can not be automatically identified and warned.
