Problems solved by technology

After the lightning arrester is discharged to the ground by the first lightning strike, the lightning protection effect on subsequent lightning strikes is very poor
Due to the large difference between the design standards complied with by lightning arresters in my country and the real lightning strike phenomenon, coupled with the poor uniformity of lightning arrester product quality, the lightning protection effect is not obvious

Abstract

The invention discloses a multi-time continuous lightning stroke lightning protection method. Lightning protection is carried out in a mode of alternating multiple groups of lightning arresters; whenbeing attacked by lightning, the first working area lightning arrester and the second working area lightning arrester are impacted by high voltage at the same time, and the first working area lightning arrester works normally and discharges to the ground; a capacitor connected in parallel with the second working area lightning arrester is charged through first lightning stroke, and the lightning arrester in the second working area discharges to the ground when being subjected to the second lightning stroke; and after discharging to the ground, a movable contact bracket rotates to alternate theworking areas, and the process is repeated. According to the lightning protection method, the lightning arresters are alternated and carrying out detection alternation process, the failed lightning arrester can be cut out in time, the qualified lightning arrester is arranged in front to receive lightning stroke, multiple continuous lightning strokes can be effectively coped, and losses caused bylightning arrester failure and other reasons during multiple continuous lightning strokes are avoided.

Description

technical field [0001] The invention relates to the technical field of lightning protection methods, in particular to a lightning protection method for multiple consecutive lightning strikes and an online screening method for lightning arresters. Background technique [0002] There are millions of lightning strikes in nature every year, and the lightning disaster is one of the ten most serious natural disasters announced by the United Nations International Decade for Disaster Reduction. The latest statistics show that the loss caused by lightning has risen to the third place of natural disasters. Every year, lightning strikes cause countless casualties and property losses around the world. According to incomplete statistics, the casualties caused by lightning strikes and the negative effects of lightning strikes in my country reach 3,000-4,000 people every year, and property losses range from 5 billion to 10 billion yuan. [0003] The poor uniformity of the raw materials a...
