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, and uses PSCAD simulation software to model the upper shaped tower and the triangular tower respectively, and simulates and analyzes the influence of lightning protection measures such as insulator type, lightning arrester installation, and lightning protection wire erection on the lightning resistance level of the line. For a 10kV distribution line supporting an oil production area, field measurement and modeling simulation were carried out, and various lightning protection measures were taken, including: using resistance reducing agents for 24 #3 poles in turn, Deeply buried grounding electrode, increase the number of suspended insulator sheets, erect a small protection angle lightning protection line for the 20 base towers before the substation outlet, optimize the lightning arresters of the three-phase insulators at both ends of some towers, etc., the lightning resistance level of the oil production line is significantly improved after optimization, and the feasibility and effectiveness of various lightning protection measures to improve the lightning resistance level of the line are theoretically verified, and finally the lightning resistance improvement strategy of the line is given, which provides a reference for the lightning protection of 10 kV distribution lines in other oil production areas.
