Embodiment Construction

[0079] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0080] A lightning protection system for distribution lines, comprising: a composite umbrella skirt 3, an upper fitting 2 is installed on the upper end of the composite umbrella skirt 3, and a lower fitting 4 is installed on the lower end of the composite umbrella skirt 3; the upper fitting 2 and the cable 1 The connection is fixed, and the fitting 2 can pierce the insulating layer of the cable 1 and communicate with the conductive core of the cable 1 .

[0081] The lower fitting 4 is equipped with a lightning-inducing convex post 5, which is conductively connected with the upper fitting 2, and the end of the lightning-inducing convex post 5 is inclined downward, and there is a certain transverse distance from the upper end of the lightning-inducing rod 6 to prevent During heavy rain, the two are connected through rainwater, resulting in leakage accidents.

Abstract

The invention relates to a lightning protection system for power distribution lines, comprising: a composite umbrella skirt; Lightning rods; connecting rods arranged in parallel, the two ends of the connecting rods are respectively hinged with the lower fittings and the support; the gap adjustment rod is connected with the lower fittings in rotation, the upper end of the gap adjustment rod is provided with a worm, the connecting rod is provided with worm teeth, and the worm Connected with worm gear drive. At the same time, a method for adjusting the lightning protection gap and a method for replacing the lightning rod are also disclosed. Its lightning protection gap is adjustable and has strong versatility, which can meet the use requirements of different types of insulators, and the installation and disassembly steps of the lightning rod are simpler, which is convenient for the maintenance and replacement of the lightning rod.

Description

technical field [0001] The invention relates to the technical field of power transmission equipment, in particular to a lightning protection system for power distribution lines. Background technique [0002] The lightning protection system is mainly used to protect various electrical equipment (transformers, switches, capacitors, wave traps, transformers, engines, motors, power cables, etc.) in power systems, railway electrification systems, and communication systems from lightning overvoltages , Operating overvoltage and other damage. The main types of lightning protection systems are tubular arresters, valve arresters and drop arresters. [0003] The drop-type (thrownable, detachable) arrester is skillfully installed on the drop-type mechanism of the drop-out fuse after refitting the distribution-type zinc oxide arrester, so that it can be operated with the help of the insulation switch under the condition of continuous power supply. It is convenient to detect, repair an...
