Abstract

The invention provides a multifunctional intelligent distribution network lightning protection system. The system comprises a transformer substation, an overvoltage isolator, a power transmission wire, a tower, a wire clamp, a wave resistance lightning rod, a grounding device, a fault diagnosis device, a signal transceiving device, a monitoring server, a mobile operation end and an insulating cross arm; the overvoltage isolator is connected in series with the transformer substation through the power transmission wire; the wave resistance lightning rod is mounted at the top end of the tower; the grounding device is mounted at the lower part of the tower; and the wire clamp is used for fixing the power transmission wire on the insulating cross arm at the upper part of the tower. Through arrangement of the wave resistance lightning rod, the fault diagnosis device and the mobile operation end, the lightning protection intelligent degree is improved, the fault elimination difficulty is reduced, maintenance is convenient, the workload is reduced, the lightning protection effect is improved, the lightning stroke risk is reduced, and popularization and use are convenient.

Description

technical field [0001] The invention belongs to the technical field of electric power lightning protection systems, in particular to a multifunctional intelligent distribution network lightning protection system. Background technique [0002] Lightning is a discharge phenomenon of the earth's atmosphere. Usually, when the electric field strength between the negatively charged thundercloud and the earth exceeds the breakdown strength of the atmosphere, a pulse discharge between the thundercloud and the earth occurs, which is what people call lightning strike. During the thundercloud discharge process, the discharge current increases sharply. At the moment when the lightning reaches the ground, the lightning current reaches tens of thousands, even hundreds of thousand amperes, and the potential difference between the two ends of the lightning channel can reach hundreds of thousands of volts. Wherever it goes, it will cause strong electromagnetic, thermal and mechanical destru...
