Abstract: The invention deals with a method and device for controlling the ignition of electric arc in the intercontact break of a disconnector during the operation of opening and closing the disconnector used in gas-insulated switchgear. The invention is characterized by the control of the supply of additional pulses of electromagnetic radiation energy to the intercontact break of the disconnector depending on instantaneous voltage values uS(t) measured on the incoming side of the disconnector or depending on instantaneous voltage values uS(t) on the incoming side of the disconnector and instantaneous voltage values uL(t) on the load side of the disconnector, with defined voltage threshold values (U1, U2) and preset time boundary values (T1, T3) during opening the disconnector or (T2, T4) during closing the disconnector, while the preset time values (T1, T3) include time moments in which the supply of energy pulses to the intercontact break is stopped, and the preset time values (T2, T4) include time moments in which supply of energy pulses to the intercontact break starts.
