[0002] Economic development leads to sustained growth in demand for electricity, and the construction of electricity is rapidly developed, the voltage level is gradually improved, and the power transmission capacity is continuously increased. China has become one of the countries with the highest AC and DC power transmission voltage level in the world.

[0003] Seasonal climate problems lead to an increasing number of forest fires. The custom of setting off fireworks or burning paper money during traditional festivals such as the Spring Festival, Tomb-Sweeping Day, and Winter Solstice is extremely easy to cause forest fires. Continuous drought also makes forest fires more likely to occur. In the season of crop harvesting, large-scale burning of straw can cause forest fires or straw fires to spread to the vicinity of overhead power transmission lines, which may result in tripping or cause unforeseen derivative effects. After the steel-cored aluminum stranded conductor is roasted by high-temperature flames, the galvanized layer is easily damaged, the steel core directly contacts the aluminum wire, and galvanic corrosion easily occurs, which leads to corrosion of the conductor, reduces the strength, increases the resistivity, and even causes strand breakage or wire breakage, affecting the safety and service life of overhead conductors. Currently, there is no research on the change in galvanic corrosion performance of power transmission lines after forest fires, and it is of great significance to investigate the corrosion impact of forest fires on power transmission lines and take active and effective preventive measures.

[0004] The patent application with publication number CN102279148A discloses an evaluation method for corrosion condition of steel-cored aluminum stranded overhead conductor. The application simulates the service environment conditions of the conductor by artificial means, conducts an accelerated corrosion test, obtains the corrosion law of the steel-cored aluminum stranded overhead conductor, and the relationship between its mechanical properties, electrical properties, and corrosion time, thereby evaluating the corrosion condition of the steel-cored aluminum stranded overhead conductor. The corrosion condition of the steel-cored aluminum stranded overhead conductor is simulated experimentally, and the single-wire tensile strength and resistivity are measured to establish the relationship between the corrosion condition of the overhead conductor under different environments and the mechanical and electrical properties of the conductor.

[0005] The patent application with publication number CN104166068A discloses a failure analysis method for steel-cored aluminum stranded conductors of power systems. The application collects relevant technical materials and conducts detection and analysis tests, and analyzes the causes of conductor failure based on the test results, wherein the detection and analysis tests include electrochemical corrosion analysis tests.
