Abstract

A high-altitude lightning arrester is disclosed. The lightning arrester is of a solid structure, and comprises a high-voltage terminal, a silicon rubber insulating jacket, a winding layer, a pluralityof resistance sheets in series, an upper electrode, a lower electrode and a ground electrode. The resistance sheets are arranged in a middle position of the lightning arrester in a stacked manner, and the winding layer covers the outer periphery of the resistance sheets and extends along the stacking direction of the resistance sheets. A silicone rubber insulating jacket is covered on the outer periphery of the winding layer; An upper electrode is arranged at the upper end of the laminated resistor sheet, the ground electrode is arranged at the lower end of the laminated resistor sheet, the lower electrode is arranged at the lower end of the ground electrode, and the high-voltage terminal is arranged at the upper end of the upper electrode. The winding layer and the silicone rubber insulating jacket are tightly wrapped around the outer periphery of the series resistor sheet to form a solid structure, and there is no gas inside the lightning arrester, which effectively solves the problems of excessive internal pressure and abnormal explosion-proof device of the existing porcelain jacket lightning arrester of a cavity structure in long-term operation.

Description

technical field [0001] The invention relates to the technical field of lightning arresters, in particular to a high-altitude lightning arrester. Background technique [0002] High-altitude areas refer to areas with an altitude of more than 1,000 meters. The meteorological characteristics are as follows: the altitude is inversely proportional to the air pressure level, that is, the higher the altitude, the lower the air pressure level, the lower the air density, the thinner, and the lower the humidity. The lower the temperature, the drier, and the thinner the air, the stronger the penetration of solar radiation, the more heat the ground absorbs during the day, the higher the temperature, and the faster and more the ground loses heat at night, the lower the temperature, resulting in a significant temperature difference between day and night , There are many windy days every year, the soil temperature is low, and the freezing period is long. As the altitude increases, the air ...
