| 内容記述 | It was reported in the previous report that the propagation constant measuring system for longdistance pipelines was produced based upon the distribution constant theory for the purpose ofmaintenance and management of long distance pipelines buried underground and to have a system todirectly measure the propagation constants and characteristic impedance of the pipeline buriedunderground. This time, a simulator for the signal propagation of a pipeline, referring to these actualmeasurement values, was constructed and various signal modes were simulated. On the prediction ofaccidents where heavy-construction equipment, such as backhoe or boring machine, has contact witha pipeline and damages the coating of pipeline, the damage simulations with a backhoe and boringmachine were performed and the fault resistances of these heavy-construction pieces of equipment atthe time of accidents were identified. As a result, it was revealed that the fault resistance generated bythe metal-to-metal contact caused by the boring machine, which damages pipeline the most, wasapproximately 20-50Ω when water was used, and that caused by the backhoe was approximately100Ω. In order to verify the detectable property of this system, a simulation was performed todetermine how each distributed constant changed when this degree of grounding faults occurred inthe monitoring section of the pipeline, and validated it with an actual pipeline. | |||||||||||||
