Abstract

Изобретение относится к области электротехники. Для обеспечения нормального процесса возбуждения электрической дуги и варки загрязненного и окисленного металла, стали, алюминия в способе возбуждения электрической дуги после размыкания закоротки выхода источника питания к нему подают форсирующее напряжение той же полярности, но большей амплитуды, после чего на дуговой промежуток подают с задержкой по времени импульс напряжения обратной полярности по отношению к источнику питания электрической дуги, превышающий по номиналу вышеуказанное форсирующее напряжение и имеющий укороченный фронт, а в устройство для возбуждения электрической дуги введены источник внутреннего форсирующего напряжения, блокировочный дроссель и элемент "длинной линии". Кроме этого, усовершенствованы источник импульсов напряжения возбуждения и магнитные ключи со способом организации их управления.Международная заявка была опубликована вместе с отчетом о международном поиске.The invention relates to the field of electrical engineering. To ensure the normal process of initiating an electric arc and cooking polluted and oxidized metal, steel, aluminum in the method of exciting an electric arc, after opening the short circuit of the power supply output, a forcing voltage of the same polarity but greater amplitude is applied to it, after which the arc period is delayed time, a voltage pulse of reverse polarity with respect to the power source of the electric arc, exceeding at the nominal value the above-mentioned boost voltage and having a shortened th front, and for driving the electrical arc device incorporated booster internal source voltage, and the throttle interlocking member "long line". In addition, the source of excitation voltage pulses and magnetic keys with the method of organizing their control have been improved. The international application was published together with an international search report.
