ЭФФЕКТИВНОЕ КОНТУРНОЕ ЭКРАНИРОВАНИЕ МАГНИТНОГО ПОЛЯ ТРЕХФАЗНЫХ КАБЕЛЬНЫХ ЛИНИЙ ПРИ ОГРАНИЧЕННОМ ТЕПЛОВОМ ВОЗДЕЙСТВИИ НА СИЛОВЫЕ КАБЕЛИ

Анотація


Предложен новый тип пассивного экрана для уменьшения магнитного поля трехфазных кабельных линий электропередачи с прокладкой кабелей по схеме «в плоскости». Разработанный одноконтурный экран имеет несимметричную магнитную связь с кабельной линией, обусловленную использованием двух разных ферромагнитных сердечников, и характеризуется подтвержденной экспериментально высокой эффективностью экранирования при минимальном тепловом воздействии на кабельную линию за счет удаления от нее экранных кабелей на расстояние 0,2÷0,3 м. Получены соотношения для определения эффективности экранирования, параметров экрана и сердечников.
