Abstract：Changes in the space electric field environment of high-voltage lines can have serious consequences. On the one hand, it affects its own stable operation and reduces the reliability of power supply; on the other hand, it brings ecological impact and damages adjacent structures. The high-speed rail passing through the overhead transmission line is fast and bulky. In order to study the influence of the space electric field disturbance on the high-speed railway transmission line, this paper uses the finite element analysis method to establish the two-dimensional electric field model of the line-high-speed rail and simulates the analysis. As a result, it can be seen that the high-speed rail passing through the overhead transmission line will cause distortion of the power frequency electric field under the line, and the distortion degree is the largest under the line, and the closer to the high-iron distortion, the more obvious; when the high-speed rail passes under the line and causes distortion, the line-to-ground distance is one. Important influencing factors. Therefore, the space electric field disturbance to the overhead transmission line across the high-speed rail is large, and it is necessary to attract attention and take necessary measures.
