Novel lightning rod with inner ring plate

Abstract

The invention discloses a novel lightning rod with an inner ring plate, and the novel lightning rod comprises an upper section steel pipe and a lower section steel pipe; an upper section flange plate is arranged on the end face, facing the lower section steel pipe, of the upper section steel pipe, a plurality of upper stiffening plates are fixed between the upper section flange plate and the upper section steel pipe, an upper inner ring plate is fixed in the upper section steel pipe, and the upper inner ring plate is flush with the top ends of the upper stiffening plates; a lower section flange plate is arranged on the end face, facing the upper section steel pipe, of the lower section steel pipe, a plurality of lower stiffening plates are fixed between the lower section flange plate and the lower section steel pipe, a lower inner ring plate is fixed in the lower-section steel pipe, and the lower inner ring plate is flush with the bottom ends of the lower stiffening plates. The lightning rod has the advantages that stress concentration is improved by additionally arranging the inner ring plate to improve the outer rigidity of the wall face of the steel pipe, meanwhile, the outer rigidity of the plane of the joint is increased, the fatigue life is prolonged, and brittle fracture accidents of the lightning rod are reduced.

Description

technical field [0001] The invention relates to a novel lightning rod with an inner ring plate. Background technique [0002] In order to avoid lightning damage to important electrical components in the substation and affect the overall operation of the power system, lightning rods need to be installed in actual substation projects to ensure the safety of electrical equipment inside the substation. The single-rod steel pipe lightning rod has been widely used in the power system due to its simple structure, easy standardization of segments, and convenient installation. Since the lightning rod is usually tens of meters high, for the convenience of transportation and production and installation, the single-rod steel pipe lightning rod is usually formed by connecting multiple sections of round steel pipes through flexible or rigid flanges. In actual engineering, in order to ensure the rigidity and bearing capacity of the joints, rigid flange connections are usually used. [00...
