Abstract

Изобретение относитс  к электротехнике и может быть использовано 5 Г дл  регулировани  мощности, потребл емой активными электронагревател ми . Цель изобретени  - повышение козффициента мощности. Регулирование мощности осуществл ют изменением фазы включени  симисторов 1-7, св зывающих нагрузку 12-14 с фазами сети 9-11 и с нулевым выводом 8. Введение симистора 7 между нулевым выводом 8 и общей точкой симисторов 1-3 увеличивает число участков регулировани , на границах которых коэффициент мощ- . ности близок к единице, до дес ти, за счет чего достигаетс  поставленна  цель. 1 ил. с « (Л 8 J // J // JThe invention relates to electrical engineering and can be used 5 G to regulate the power consumed by active electric heaters. The purpose of the invention is to increase the power coefficient. The power control is carried out by changing the switching phase of the triacs 1-7, connecting the load 12-14 with the phases of the network 9-11 and with the zero output 8. The introduction of the triac 7 between the zero output 8 and the common point of the triacs 1-3 increases the number of control sections the boundaries of which power ratio-. close to one, up to ten, whereby the goal is achieved. 1 il. with "(L 8 J // J // J
