Abstract

For å kunne avbryte en elektrisk strøm med en effektbryter (1) med et gassrett hus (2), som er tylt med en slukkegass og hvor i det minste en hovedkontakitrinretning (10, 13) er anordnet, som omfatter en fast kontakt (13) og en bevegelig kontakt (10), hvorved hver hovedkontakitnnretning (10, 13) er elektrisk parallelt koblet til en lysbue-kontaktinnretning, som kommer etter hovedkontaktinnretningen (10, 13) i bryterbevegelsen og som er utrustet med en slukkespole for å slukke en lysbue, hvor kommutering av strømmen ved lysbuekontaktinnretningen ved adskillelse av hove<lkontaktinnretningen (10, 13) akselereres, foreslår man at ved hovedkontaktinnretningen (10, 13) anordnes et lysbuekjøleelement (16) som omfatter i det minste et vekselvirkningsavsnitt (18) for avkjøling av lysbuen under bryterprosessen.In order to be able to interrupt an electric current with a circuit breaker (1) with a gas-straight housing (2), which is filled with an extinguishing gas and in which at least one main contact direction (10, 13) is arranged, which comprises a fixed contact (13) and a movable contact (10), each main contact device (10, 13) being electrically connected in parallel to an arc contact device, which follows the main contact device (10, 13) in the switch movement and which is equipped with an extinguishing coil for extinguishing an arc, where commutation of the current at the arc contact device is accelerated by separating the main contact device (10, 13), it is proposed that at the main contact device (10, 13) an arc cooling element (16) is provided which comprises at least one interaction section (18) for cooling the arc below the switch process.
