Abstract
1. Мобильный генератор тока для плавки гололеда на проводах воздушных линий электропередачи (ВЛ), содержащий источник электрической энергии, проводники с клеммами для его подключения к проводам ВЛ и электрические шины для соединения проводов ВЛ на пролете между опорами по схеме плавки гололеда, отличающийся тем, что в качестве источника электрической энергии использованы два дизельных электрических генератора, выпрямленное напряжение которых соединено либо последовательно, либо параллельно в зависимости от требуемой для плавки величины тока, обеспечивая повышение выходного напряжения при больших сопротивлениях цепей. ! 2. Мобильный генератор тока для плавки гололеда по п.1, отличающийся тем, что посредством полупроводникового преобразователя, обеспечивающего режим источника тока, достигается мягкий режим работы дизель - генераторов. ! 3. Мобильный генератор тока для плавки гололеда по п.1, отличающийся тем, что режим источника тока полупроводникового преобразователя обеспечивает постоянство заданного тока плавки гололеда независимо от электрического сопротивления проводных цепей и цепей заземления. ! 4. Мобильный генератор тока для плавки гололеда по п.1, отличающийся тем, что его схемное решение обеспечивает плавку гололеда на фазных проводах и грозозащитном тросе ВЛ, в том числе при исполнении грозозащитного троса с заземлением на каждой опоре, на длине до двух пролетов ВЛ. 1. A mobile current generator for melting ice on the wires of overhead power transmission lines (OHL), containing a source of electrical energy, conductors with terminals for connecting it to the wires of the OHL, and busbars for connecting the wires of the OHL on the span between the supports according to the ice melting scheme, characterized in that two diesel electric generators are used as a source of electrical energy, the rectified voltage of which is connected either in series or in parallel, depending on the value required for melting current, providing an increase in the output voltage at high resistance circuits. ! 2. The mobile current generator for melting ice according to claim 1, characterized in that by means of a semiconductor converter providing a current source mode, a soft mode of operation of diesel generators is achieved. ! 3. The mobile current generator for melting ice according to claim 1, characterized in that the current source mode of the semiconductor converter ensures the constancy of a given current for melting ice, regardless of the electrical resistance of the wire and ground circuits. ! 4. The mobile current generator for melting ice according to claim 1, characterized in that its circuit solution provides melting of ice on phase wires and a lightning protection cable for overhead lines, including when performing a lightning protection cable with grounding on each support, for a length of up to two overhead runs .
