Abstract: In recent years, China's power industry is booming, the power enterprises are increasing, and the power load is growing rapidly, resulting in the doubling of line safety work pressure. In order to ensure the electric power supply needed by people's daily life, further improve the safe operation level of electric power transmission lines, and ensure the normal transportation of electric energy, the operation and maintenance level of power transmission lines should be continuously improved in the existing technology. Based on this, this paper will discuss the problems existing in power transmission lines and solutions, and propose corresponding strategy analysis to provide reference for the operation and maintenance technicians of power transmission lines.

在電力系统中,提高输电线路的稳定性和安全性,不仅能起到改善电能质量的作用,还能降低维修成本。而随着供电量需求的逐渐增大,对输电线路的运维工作提出了更高的要求。受到气候条件、地理位置等因素的影响,输电线路维护维修工作开展困难。因此,电力企业更需积极探索,不断创新,为进一步提升输电线路的运行维护水平做出努力。
1 影响电力输电线路运行维护的主要因素
1.1 外力破坏因素
通常情况下,输电线路会架设在外界环境中,比如:山区和稻田,由于所处环境的特殊性,有些线路会横穿稻田和山区,而农民们会在稻田里进行农事操作,焚烧秸秆等以及工人们会在山区进行机械操作。山区树枝的刮碰、机械施工操作、秸秆焚烧产生的农烟等这些行为都会对电力线路的安全运行造成威胁,致使线路维修维护困难。另外,在输电线路附近会有人偷盗电缆电线,这也是造成输电线路正常运行的主要原因之一。……
