Abstract

Изобретение относится к миниатюрному прерывателю цепи, содержащему поворотную приводную пластину 16, перемещающую подвижный контактный рычаг 12, расцепитель 18 для автоматического прерывания в случае аварии и рукоятку 20 для ручного приведения в действие. Для увеличения изолирующего расстояния и электрической прочности пластина 16 снабжена ограничителем 70 движения, удаленным соответственно от оси 42 контактного рычага 12 на величину первого радиуса R1 и от оси 14 - на величину второго радиуса R2, причем разность длин радиусов R1 R2 допускает увеличенный угол β открытия контактного рычага 12, который больше, чем угловое перемещение α пластины 16.The invention relates to a miniature circuit breaker comprising a rotatable drive plate 16 moving a movable contact arm 12, a release 18 for automatic interruption in the event of an accident, and a handle 20 for manual actuation. To increase the insulating distance and electric strength, the plate 16 is equipped with a movement limiter 70, which is removed from the axis 42 of the contact lever 12 by the value of the first radius R1 and from the axis 14 by the size of the second radius R2, and the difference in the lengths of the radii R1 R2 allows an increased contact opening angle β the lever 12, which is greater than the angular displacement α of the plate 16.
