Problems solved by technology

[0005] (1) The lightning protection gap cannot be adjusted. For different types of insulators, it is necessary to replace the lightning arresters with various specifications of lightning protection gaps
[0006] (2) In the traditional drop-type lightning protection device, the installation and disassembly of the lightning rod requires multiple steps, the operation is complicated, and operation errors are prone to occur, resulting in safety accidents

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 of a distribution line. The lightning protection system comprises a composite umbrella skirt; an upper hardware fitting; a lower hardware fitting; a lightning guiding convex column which is arranged at the lower end of the upper hardware fitting; a support which is provided with a detachable lightning rod; parallel connecting rods, wherein thetwo ends of the connecting rods are respectively hinged with the lower hardware fitting and the support; a gap adjusting rod which is rotationally connected with the lower hardware fitting, wherein aworm is arranged at the upper end of the gap adjusting rod, worm teeth are arranged on the connecting rods, and the worm is in transmission connection with the worm teeth. Meanwhile, the invention further discloses an adjusting method of the lightning protection gap and a replacing method of the lightning rod. The lightning protection gap is adjustable, the universality is high, the use requirements of different types of insulators can be met, the mounting and dismounting steps of the lightning rod are simpler, and the lightning rod is convenient to overhaul and replace.

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...
