Abstract
1. Способ компенсации реактивной мощности в питающей сети переменного тока промышленных предприятий и/или индивидуальных потребителей, заключающийся в установлении в каждой линии питающей сети вентильного моста, имеющего во входной цепи со стороны питающей сети по меньшей мере один конденсатор, и пропускании выходного тока вентильного моста через нагрузку, обеспечивающую регулирование тока, протекающего через этот конденсатор, отличающийся тем, что в качестве нагрузки используют по меньшей мере один светодиод.2. Способ по п.1, отличающийся тем, что выходной ток вентильного моста, поступающий на светодиод, предварительно сглаживают резисторно-емкостным фильтром, подключенным к выходным полюсам вентильного моста, а затем пропускают через последовательно соединенные регулятор тока и токоограничивающий резистор, причем для формирования напряжения на управляющем электроде регулятора тока используют опорный резистор, подключенный параллельно светодиоду.3. Способ по п.2, отличающийся тем, что дополнительно к резисторно-емкостному фильтру подключают ограничитель напряжения, обеспечивающий защиту светодиода, срезая скачки напряжения, возникающие в питающей сети.4. Способ по любому одному из пп.1-3, отличающийся тем, что во входную цепь вентильного моста параллельно конденсатору, формирующему напряжение на вентильном мосту, включают сглаживающую индуктивность.1. A method of compensating reactive power in an alternating current supply network of industrial enterprises and / or individual consumers, which consists in installing a valve bridge in each line of the supply network having at least one capacitor in the input circuit from the supply network side and transmitting the output bridge current through a load, providing regulation of the current flowing through this capacitor, characterized in that at least one LED is used as the load. 2. The method according to claim 1, characterized in that the output current of the valve bridge supplied to the LED is pre-smoothed by a capacitance filter connected to the output poles of the valve bridge, and then passed through a series-connected current regulator and a current-limiting resistor, and to form a voltage on The control electrode of the current regulator uses a reference resistor connected in parallel with the LED. 3. The method according to claim 2, characterized in that in addition to the resistive-capacitive filter, a voltage limiter is connected, which protects the LED, cutting off voltage surges that occur in the supply network. The method according to any one of claims 1 to 3, characterized in that the smoothing inductance is switched on in the input circuit of the valve bridge parallel to the capacitor generating voltage on the valve bridge.
