Lightning strike is a manifestation of tripping of transmission lines, but in the test of electric shock and lightning strike, the failure rate is shown, the line lightning strike shows the failure rate, the line lightning strike cannot be completely triggered, and the line jumping causes the line jumping phenomenon.
Oxide resistors have good nonlinear characteristics, large flux, low residual voltage level, fast response time and no freewheeling. The application of high potential gradient resistors in line lightning protection will reduce the number of resistors, thus The volume and weight of the lightning protection device are greatly reduced, which is conducive to its installation in the line; the high-gradient lightning protection device with a series gap can greatly improve the long-term working conditions of the valve plate, and the valve plate is tested and screened during product manufacturing. The requirements are relatively lower than ordinary arresters, and the price is also cheaper; moreover, when lightning strikes, the action of the high-gradient lightning protection device prevents the line from tripping and improves the power supply reliability of the power grid.
