Overvoltage protection system for the protection of a terminal against overvoltages, as well as method for establishing an overvoltage protection system

摘要

Overvoltage protection system for the protection of a terminal (3) against overvoltages, consisting of one or more, the terminal (3) upstream over-voltage protection devices (4, 5), wherein the electrical output values of the respective over voltage protection device (4, 5) on the electrical input values of the downstream terminal (3) or of a further downstream over voltage protection device (5) are matched in terms of energy and a stepwise energy conversion and voltage limitation takes place, characterised in thatthe overvoltage protection devices are designed as modules, each of which consists of a arranged at the input side of the surge arresters (6) and a arranged on the output side impedance (7), whereby the impedance (7) a resistance wire - a coreless coil which is both for decoupling as well as for the reduction of the to a following a voltage surge protection device (5) to be protected, or to an energy output terminal (3) is used, and wherein the resistance of this impedance (7) is substantially smaller than the resistance value of the eingangsimpedeanz of the terminal (3), as well as significantly greater than the resistance value of the input impedance of a possibly downstream-connected further over voltage protection device (5), andthat the overvoltage protection devices (4, 5) with a..
