Abstract

The invention provides a corona field lightning arrester and a lightning arresting method thereof. The corona field lightning arrester comprises a metal housing. The metal housing is uniformly provided with a plurality of discharge levers at intervals; the upper end of each discharge lever is provided with a plurality of upper discharge electrodes; the lower end of the metal housing is connected with a discharge cylinder; the discharge cylinder at the lower end of the metal housing is internally provided with an insulation support; the upper end of the insulation support is connected with thedischarge lever arranged at the top end of the metal housing; the lower end of the insulation support is connected with a lower discharge electrode; a discharge gap is arranged between the outer wallof the lower discharge electrode and the inner wall of the discharge cylinder; the lower end of the lower discharge electrode is connected with a transition section support through an insulation pad plate; and the lower discharge electrode is connected to the ground through a grounding wire. The corona field lightning arrester has the advantages of reasonable structure design, no need of a power supply, utilization of thundercloud electric field self-excited corona discharge, reliable and stable lightning arresting, no negative impact on the surrounding facilities, easy installation, high windresistance and online monitoring and the like.

Description

Technical field: [0001] The invention relates to the technical field of lightning protection, in particular to a corona field lightning driving device and a lightning driving method thereof. Background technique: [0002] For more than 270 years, the international lightning protection community has mainly used the lightning rod (lightning receptor) invented by Franklin, which attracts the thundercloud electric field to concentrate near its metal needle and increases the electric field intensity at the needle end, so that the thundercloud electric field breaks down the metal needle and will The powerful lightning current leaks into the ground through its grounding body. This kind of lightning rod has the advantages of simple structure, relatively stable performance and easy maintenance, but it has a small protection angle, high requirements for grounding resistance, and risks of contact voltage and step voltage, causing personal injury; The induction current is formed on the...
