【Abstract】 Damage and leakage of gas pipelines lead to property losses and casualties. Detection of natural gas for trunk lines can reduce accidents and ensure the safety of natural gas transportation. To cope with the power supply issue for the testing instrument in the main gas pipe network, a kind of pipeline generator that harvesting the pipeline fluid kinetic energy for power supply has been developed. Structural optimization of the motor parameters including electromagnetic parameters has been numerically investigated and validated. The experimental results demonstrate that the developed pipe generator can meet the design requirements.更多还原
