Abstract

Изобретение относитс  к электротехнике . Целью изобретени   вл етс  упрощение конструкции. Устройство состоит из электродинамически взаимодействующих элементов токопровода 1, соединенных между собой гибкой св зью 2, подвижного контакта 3, неподвижного контакта 4, установленного на сферической опоре 5 и поджатого пружиной 6 к упору 7. При протекании че- рез элементы токопровода 1 тока, равного току срабатывани  и более, подвижный элемент токопровода 1 с подвижным контактом 3 под действием электродинамических сил, поворачива сь по часовой стрелке, касаетс  неподвижного контакта 4. Подвижный элемент с контактом 3 поворачивает неподвижный контакт 4 на опоре 5 до касани  второй точкой. 3 ил. (ЛThe invention relates to electrical engineering. The aim of the invention is to simplify the design. The device consists of electrodynamically interacting elements of conductor 1 interconnected by a flexible coupling 2, a movable contact 3, a fixed contact 4 mounted on a spherical support 5 and pressed by a spring 6 to the stop 7. When the current passes through the elements 1 and more, the movable element of the conductor 1 with the movable contact 3 under the action of electrodynamic forces, rotates clockwise, touches the fixed contact 4. The movable element with contact 3 rotates fixed contact 4 on support 5 until it touches the second point. 3 il. (L
