Problems solved by technology

When there is lightning in the feeding tube, the result of "equipotential connection" is that there is a lightning potential difference between the equipment. If the lightning potential difference is too large, the equipment will be damaged. For example, microelectronic equipment, the lower the working voltage of the component, the more likely it will be damaged.

Abstract

The invention provides a weak-PD (potential difference) lightning protection method based on lightning arresting. According to the method, a lightening arrester is manufactured and used for reducing lightning current, so that PD damaging equipment is not produced by the lightning current; the purpose of lightning protection can be achieved with separate use of the lightning arrester, and the lightning arrester can replace an SPD (surge protection device) equipotential connection lightning protection circuit for lightning protection; under matching use of the lightning arrester and an equipotential connection lightning protection technology, lightning current can be reduced substantially, residual PD of the equipotential connection lightning protection technology can be reduced greatly, SPDbreakdown is prevented, the SPD can also be canceled, and a better lightning protection effect is realized.

Description

Technical field [0001] Lightning resistance lagging weak potential difference lightning protection method is a method of using lightning resistance lagging device to realize the weak potential difference lightning protection of equipment room equipment. Due to work needs, the equipment in the computer room must be connected to a grounded power transformer for power supply, and also connected to external equipment to complete the work, so that the external metal conductor or grounded power supply may transmit lightning to the equipment in the electrical room and damage it For equipment, we invented the "Lightning Resistance Hysteresis Device Weak Potential Difference Lightning Protection Method" to prevent lightning from damaging the equipment by ensuring that the lightning voltage does not damage the equipment's weak potential difference and preventing lightning damage to the equipment. Background technique [0002] GB50343-2012 Building Electronic Information System Lightning Pr...
