Abstract:Zaščitno stikalo na diferenčni tok za nazivne tokove do 125 A podjetja Iskra je v fazi razvoja naletelo na problem električnega obloka, ki je nekontrolirano gorel v gasilni komori in se pri tem širil v notranjost stikala. Z analizo smo prikazali električno polje v prostoru in nato izvedli spremembe na podlagi izkušenj, s katerimi smo vplivali na spremembo električnega polja ter posledično tudi na električni oblok. Naš cilj je bil obvladati električni oblok do te mere, da smo ga uspeli usmeriti proti izpuhu, s čimer smo skrajšali čas trajanja pojava električnega obloka in odgorevanja kontaktnih materialov, do katerega pride v času gorenja električnega obloka.

Title:Extinguishing the electric arc in the rccb for high currents
Abstract:The residual current circuit breaker for rated current up to 125 A from Iska company encountered a problem with an electric arc during the development phase, which burned uncontrollably in the arc control device and spread into the interior of the switch. The analysis showed the electric field in the arc control device, then we made changes based on the experience, with which we impact the electric field and consequently on the electric field. Our goal was to control the electric arc so we were able to direct it towards the exhaust. This reduce the duration of electric arc and the combustion of contact materias that occur during the burning of the electric arc.
Keywords:residual current circuit breaker, electric arc, arc control device, electric field
