Abstract:To improve the lightning resistance level of 10 kV distribution lines in the oil production area, this paper systematically studies the lightning protection status of 10 kV distribution lines, discusses the advantages and disadvantages of various lightning protection measures, uses PSCAD simulation software to model the inverted F-shaped pole tower and triangular pole tower respectively, simulates and analyzes the impact of lightning protection measures such as insulator type, lightning arrester installation, and lightning protection wire erection on the lightning resistance level of the line.Then, through the field measurement and modeling simulation of a 10 kV distribution line in an oil production area, the feasibility and effectiveness of a number of lightning protection measures are analyzed and verified. Finally, the measures such as applying resistance reducing agent to and deeply burying the grounding electrode for 24 #3 poles, setting lightning protection wires on the first 20 poles and towers of the line, and connecting parallel line arresters at both ends of the three-phase insulators of some poles and towers are adopted. The simulation results show that the overall lightning resistance level of the line is significantly improved after taking the above optimization measures. The lightning protection optimization scheme formulated in this paper is universal, which can provide reference for lightning protection of 10 kV distribution lines in other oil production areas.
