Claims (3)

1. Способ гашения дуги однофазного замыкания на землю в паузе ОАПВ линии электропередачи с шунтирующим трехфазным реактором и однофазным заземляющим реактором в нейтрали его сетевой обмотки, шунтированным выключателем в нормальном режиме, отличающийся тем, что в качестве шунтирующего реактора используется пофазно управляемый реактор с подмагничиванием, вторичная обмотка управления которого, соединенная в треугольник, в цикле паузы ОАПВ одновременно с расшунтированием заземляющего нейтрального реактора шунтируется на время гашения дуги дополнительным трехфазным выключателем 35 кВ, фазы которого подключены параллельно каждой фазе обмотки управления реактора.1. The method of extinguishing an arc of a single-phase earth fault in a pause of an OAPV power line with a shunt three-phase reactor and a single-phase grounding reactor in the neutral of its mains winding, a shunt switch in normal mode, characterized in that a phase-controlled reactor with bias is used as a shunt reactor the control winding of which, connected in a triangle, in the pause cycle of the OAPV simultaneously with the unloading of the grounding neutral reactor, is bypassed for the time of quenching Ugi additional three-phase 35 kV switch, the phases of which are connected in parallel with each phase reactor control winding. 2. Способ по п.1, отличающийся тем, что в цикле ОАПВ соответствующей фазой выключателя 35 кВ шунтируется одна фаза вторичной обмотки управления реактора, соответствующая фазе линии передачи, на которой произошло однофазное замыкание и осуществляется цикл ОАПВ.2. The method according to claim 1, characterized in that in the OAPV cycle, the corresponding phase of the 35 kV circuit breaker shunts one phase of the secondary control winding of the reactor, corresponding to the phase of the transmission line on which the single-phase circuit occurs and the OAPV cycle is carried out. 3. Способ по п.1, отличающийся тем, что отсутствует выключатель, шунтирующий фазы вторичной обмотки управления, а компенсация емкостного тока дуги осуществляется предельным насыщением "здоровых" фаз реактора в цикле ОАПВ командой форсировки от системы автоматического управления.3. The method according to claim 1, characterized in that there is no switch shunting the phases of the secondary control winding, and the compensation of the capacitive arc current is carried out by saturating the “healthy” phases of the reactor in the OAPV cycle by force command from the automatic control system.
