摘　　要：为实现天然气管道运输中运输效率与实时监测,本文基于环氧树脂绝缘填料,制备了一种更耐高温的绝缘材料,并将其应用于基于风力机发电原理的燃气管道内置发电机装置的接线柱,获得可以同时进行发电与数据的监控采集的管道内置发电装置。同时,为最大限度利用管道内压力能,对管道内置发电工艺进行了设计与仿真试验。结果显示:叶片旋转半径只与管道半径有关,与其他参数无关;气体密度与发电机械效率正相关,气体密度与发电机械效率共同决定了发电最大功率;升力型发电最大力矩70N.M,发电功率35~55 kW,该装置适用于中高压天然气管道发电,但发电功率波动范围大;阻力型叶片更宽更重,转速更低,发电最大力矩16 N.M,发电功率41~92 W,该装置只适用于调压站内监测装置供电。In order to achieve transportation efficiency and real-time monitoring of natural gas pipeline transportation,this paper prepares a higher temperature resistant insulation material based on epoxy resin insulation filling,and applies it to the terminal of a gas pipeline built-in generator device based on wind turbine power generation principle,obtaining a pipeline built-in power generation device that can simultaneously generate electricity and monitor data collection.Meanwhile,to maximize the utilization of pressure energy inside the pipeline,design and simulation experiments were conducted on the built-in power generation process in the pipeline.The results showed that the blade rotation radius was only related to the pipeline radius and was independent of other parameters.Gas density was positively correlated with the efficiency of power generation machinery,and together with the efficiency of power generation machinery,gas density determined the maximum power generation.The maximum torque for lift type power generation was 70 N.M.The power generation was between 35 kW and 55 kW,and this device was suitable for medium and high-pressure natural gas pipeline power generation,but the fluctuation range of power generation was large.Resistance type blades were wider and heavier,with lower rotational speed and a maximum torque of 16 N.M.The power generation was 41~92 W,and this device was only suitable for supplying power to monitoring devices inside the regulating station.
