Abstract

A device for protecting, in a multiphase electric power plant for alternating voltage, one or more objects from over-currents and/or over-voltages, said objects being connected to an electric power network or another equipment comprised in the electric power plant, said device comprising an arrangement for reducing over-currents and/or over-voltages, said arrangement being activatable with the assistance of an arrangement detecting over-current and/or over-voltage conditions. The arrangement reducing over-currents and/or over-voltages comprises a plurality of electric closing means (9a), which each are coupled to phase conductors in the plant and which are closable to reduce occurring over-currents and/or over-voltages. Said plurality of closing means (9a) have their electrode gaps (16a) arranged within an enclosure (22a) common to the closing means. The device and the closing means (9a) thereof may also be used for general switching purposes.
