强腐蚀地区输电线路腐蚀及监测防护的研究现状

Research Status of Corrosion and Monitoring Protection of Transmission Lines in Serious Corrosion Area

随着我国电力事业的发展,输电线路上金属构件的腐蚀问题也逐渐凸显,尤其在工业重污染区、沿海地区等强腐蚀环境中,热镀锌金属构件的防腐蚀作用大幅减弱,很难满足服役要求。在实地勘察的基础上,结合各部件的工作特点和服役状态,对输电杆塔、导线、金具等金属构件的腐蚀现状和机制进行了总结分析,并研究了输电线路设施的监测防护技术发展状况,为输电网的安全稳定运行提供支持。

With the development of China′s electric power industry, the corrosion of metal components on the transmission line also becomes increasingly. Especially in strong corrosion environment such as industrial heavily polluted areas and coastal areas, the anti-corrosion effect of hot-dip galvanized metal components is greatly weakened, it is difficult to meet the service requirements. Based on the on-the-spot investigation, combined with the working characteristics and service status of each component, the corrosion status and mechanism of metal components such as transmission towers, wires and fittings are summarized, and the monitoring and protection technology of transmission line facilities are studied. This article may provid support for the safe and stable operation of transmission network.
