Abstract

The invention discloses a multiple-pulse synchronous thunder and lightning isolating inhibiting unit. The multiple-pulse synchronous thunder and lightning isolating inhibiting unit comprises a band elimination filter, wherein a first end of the band elimination filter is connected with a port of a strong lightning area; a second end of the band elimination filter is connected with an equipment port of a protected area; and impedance of the band elimination filter increases along with increase of lightning wave frequency. The invention also discloses a multiple-pulse synchronous thunder and lightning isolating inhibiting circuit and meanwhile discloses a multiple-pulse synchronous thunder and lightning isolating inhibiting method. The multiple-pulse synchronous thunder and lightning isolating inhibiting unit, circuit and method has the advantages of avoiding dependence on cable characteristics, enabling most part of invasion of lightning current to be blocked and isolated and taking a good lightning protection effect on protected equipment.

Description

technical field [0001] The invention relates to the technical field of lightning protection, in particular to a multi-pulse synchronous lightning isolation and suppression unit. [0002] The invention also relates to a multi-pulse synchronous lightning isolation and suppression circuit. [0003] The invention also relates to a multi-pulse synchronous lightning isolation and suppression method. Background technique [0004] The existing lightning protection technology is based on the characteristics of lightning overvoltage, and the nonlinear device that converts high impedance into low impedance instantaneously is connected in parallel in the power line. When lightning invades, start the overvoltage protection device of the nonlinear device, provide bypass shunt, voltage division, and discharge channels for the power line, and discharge the lightning current to the ground network, and rely on multi-level lightning protection measures to reduce the line or equipment. Reduce...
