Abstract

Устройство и способ для равномерного распределения электрической нагрузки (ответвленная цепь 1-5) через схему разводки трехфазного электропитания. Ток в каждой входящей фазе и в каждой ответвленной цепи измеряется множеством датчиков тока (16-20 и 42-50). Выходной сигнал датчиков тока (16-20 и 42-50) находится под постоянным контролем процессора (12). С каждой ответвленной цепью (BRANCH CIRCUIT 1-5) связаны мультипольный переключатель (22-30) и обычный автоматический выключатель (14). Каждый переключатель (22-30) способен соединять свою соответствующую ответвленную цепь (BRANCH CIRCUIT 1-5) с любой входящей фазой или отсоединять ответвленную цепь (BRANCH CIRCUIT 1-5) от всех трех фаз. Процессор (12) периодически контролирует электрический ток, проходящий через каждую входящую фазу, и, основываясь на состоянии нагрузки в ответвленной цепи, программирует работу переключателей (22-30), чтобы удерживать нагрузки ответвленных цепей (BRANCH CIRCUIT 1-5) равномерно распределенными по всем трем входящим фазам. По другому варианту схема суммирования (52) объединяет допустимые нагрузки по току всех трех входящих фаз в одиночный суммированный выходной сигнал. Затем этот выходной сигнал выпрямляется и используется для генерирования (56) однофазового напряжения переменного тока, который подается во все ответвленные цепи (BRANCH CIRCUIT 1-5) системы.Международная заявка была опубликована вместе с отчетом о международном поиске.
