电气化铁路对埋地天然气管道交流干扰电压的影响

Effect of Electrified Railway on AC Disturbance Voltage of Buried Natural Gas Pipeline

天然气是一种清洁能源,作为改善环境的一项措施,近年来被广泛推广应用于居民用气、工业燃料、化学化工、电力工业等。但由于天然气本身具有易燃易爆的危险性,每年因天然气管道腐蚀穿孔引起的燃爆类安全事故屡屡发生。所以,了解天然气管道周围杂散电流的干扰程度,及时监测管道的腐蚀情况并采取合理有效的防护措施,对延长管道的使用寿命,保证管道的安全运行具有十分重要的意义。本工作主要对电气化铁路对埋地天然气管道交流电压的影响进行论述。

Natural gas is a high-quality clean energy source that can improve ecological environment. In recent years, natural gas has been widely recommended for civil usage, industrial fuel, chemical industry, and electrical industry. However, natural gas has certain risks of ignition and high dangerous explosion. Every year, the corrosive of natural pipe occurs frequently, therefore, for prevention and safety, it must be monitoring the gas pipe on time, check the corrosion on the pipe and engaged protection on the surface of pipe or surrounding area will extent the life span or durability of the gas pipe. This mainly discuss about electrified railway cause by voltage explosion in natural gas pipe.
