Description

Общеизвестна эффективность - с металлургической и энергетической точек зрени  - выполнени  руднотермических печей с круглой ваН ной. Применение в такой печи шести электродов, питаемых от двух трехфазных систем по схеме «треугольник на электродах, т. е. так, ч го к каждому электроду подводитс  начало одной и конец другой фа:(ы вторичных обмоток трансформатора, позвол ет повысить мощность круглой печи и улучшить ее электрические показатели - коэффициент мощности и к.п.д.It is well known efficiency - from the metallurgical and energy point of view - to perform ore-smelting furnaces with a round bath. The use of six electrodes in such a furnace, fed from two three-phase systems according to the triangle on electrodes scheme, i.e., so that each electrode is fed to the beginning of one and the end of the other phase: (the secondary windings of the transformer increase the power of the round furnace and improve its electrical performance - power factor and efficiency

Однако при этом затруднительно разместить шесть электродов в круглой ванне так, чтобы подведенна  мощность распределилась достаточно равномерно по всему сечению без образовани  мертвых зон и так, чтобы нагрузка фаз была симметричной или близкой к ней.However, it is difficult to place the six electrodes in a round bath so that the supplied power is distributed fairly evenly over the entire cross section without the formation of dead zones and so that the phase load is symmetrical or close to it.

С целью возможности получени  равномерного распределени  мощности по всему сечеиию горна предлагаетс  п ть из шести электродов расположить по ьершинам равностороннего п тиугольника, а шестой электрод - в центре печи.In order to make it possible to obtain a uniform power distribution throughout the furnace hearth, it is proposed to place five of the six electrodes along the bars of an equilateral pentagon, and the sixth electrode in the center of the furnace.

На чертеже схематически показано предлагаемое размещение электродов в круглой руднотермической печи.:The drawing schematically shows the proposed placement of electrodes in a round ore-smelting furnace .:

В круглой ванне п ть электродов /-5 .размещаютс  по вершина.1 равностороннего п тиугольника, а щестой электрод 6 находитс  в цен-тре печи и п тиугольника. Питание печк производитс  от двух трехфазных или шести однофазных трансформаторов по схеме «треугольник на электродах, т. е. так, что к каждому электроду подводитс  начало одной и конец другой фазы вторичных обмоток трансформатора.In a circular bath, five electrodes of / -5. Are placed along the top of an equilateral pentagon, and the scattering electrode 6 is located at the center of the furnace and the pentagon. The stoves are powered from two three-phase or six single-phase transformers in a "triangle on electrodes" circuit, i.e., so that each electrode is fed to the beginning of one and the end of the other phase of the secondary windings of the transformer.

В электрическом отношении система не строго симметрична, но достаточно близка к ней, поскольку взаимоиндуктивность между электрск дами одинакова дл  всех фаз и только небольшой участок токоподводл к центральному электроду в районе ванны отличен от других.Electrically, the system is not strictly symmetrical, but rather close to it, since the mutual inductance between the electrodes is the same for all phases and only a small portion of the current lead to the central electrode in the bath area is different from the others.
