Embodiment Construction

[0074] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0075] A lightning protection system for power distribution lines, comprising: a composite umbrella skirt 3, an upper metal fitting 2 is installed on the upper end of the composite umbrella skirt 3, and a lower metal fitting 4 is arranged on the lower end of the composite umbrella skirt 3; the upper metal fitting 2 and a cable 1 Fixed connection, and the fitting 2 can pierce the insulating layer of the cable 1 and communicate with the conductive core of the cable 1 .

[0076] The lower metal fitting 4 is provided with a lightning guide post 5, which is electrically connected to the upper metal fitting 2. The end of the lightning guide post 5 is inclined downward, and there is a certain lateral distance from the upper end of the lightning rod 6 to prevent During heavy rain, the two are connected through rainwater, resulting in an electric leakage accident.

Abstract

The invention relates to a method for replacing a lightning rod, which uses a lightning protection system of a distribution line. Fitting mounting; a lower fitting; the lightning triggering convex column is arranged at the lower end of the upper fitting; the support is provided with a detachable lightning rod; two ends of the connecting rod are respectively hinged with the lower fitting and the support; and the gap adjusting rod is rotatably connected with the lower fitting, the upper end of the gap adjusting rod is provided with a worm, the connecting rod is provided with worm teeth, and the worm is in transmission connection with the worm teeth. The installation and disassembly steps of the lightning rod are simpler, and the maintenance and replacement of the lightning rod are facilitated.

Description

technical field [0001] The invention relates to the technical field of power transmission equipment, in particular to a method for replacing a lightning rod. Background technique [0002] Lightning protection system is mainly used to protect various electrical equipment (transformers, switches, capacitors, wave arresters, transformers, engines, motors, power cables, etc.) in power systems, railway electrification systems, and communication systems from lightning overvoltage , operation overvoltage and other damage. The main types of lightning protection systems are tubular arresters, valve arresters and drop arresters. [0003] The drop-type (castable, detachable) arrester is a refitted zinc oxide arrester of the distribution type and cleverly installed on the drop-type mechanism of the drop-type fuse, so that it can be operated by means of an insulating switch in the case of uninterrupted power supply. The pole can easily detect, repair and replace the arrester, which not...
