Description

Насто щее изобретение относитс  к автоматическим выключател м с выдержкой времени, снабженным биметаллической пружиной дл  привода силовых и вспомогательных контактов в цепи нагревательного элемента.The present invention relates to time-delay circuit breakers equipped with a bimetallic spring for driving the power and auxiliary contacts in the circuit of the heating element.

Предлагаемый выключатель отличаетс  от известных тем, что управление силовыми контактами осуществлено в нем при помощи кулачковой щайбы, укрепленной, на одном валу с поворотной руко ткой выключател  и снабженной подпружиненным храповиком, который механически св зан с биметаллической пружиной.The proposed switch differs from the known ones in that the control of the power contacts is carried out in it by means of a cam plate, reinforced, on the same shaft with a rotary knob of the switch and equipped with a spring-loaded ratchet, which is mechanically connected to the bimetallic spring.

Такое выполнение выключател  позвол ет регулировать врем  срабатывани .This embodiment of the switch allows you to adjust the response time.

На чертеже изображена схема предлагаемого выключател .The drawing shows a diagram of the proposed switch.

Автоматический выключатель приводитс  в действие подвижной руко ткой 1, на одном валу с которой посажена кулачкова  шайба 2, воздействующа  на подвижные силовые контакты 3, через которые проходит ток нагрз зки. Шайба 2 снабжена подпружиненным храповиком 4, который, механически св зан посредством рычагов 5 и б с биметаллической пружиной 7.The circuit breaker is driven by a movable knob 1, on the same shaft with which a cam washer 2 is fitted, acting on the movable power contacts 3 through which the load current passes. The washer 2 is provided with a spring-loaded ratchet 4, which is mechanically connected by means of levers 5 and b with a bimetallic spring 7.

Обмотка нагревательного элемента 8 этой пружины подключаетс  к сети с помощью выключател  9. При нагреве биметаллической пружины она воздействует через подвижный рычаг 6 на храповик 4 и руко тку 10 выключател  9. При этом храповик 4 поворачивает кулачковую щайбу 2, а руко тка 10 отключает нагревательный элемент 8 от питающей сети, что вызывает охлаждение биметаллической пружины. При охлаждении пружины описанный процесс происходит в обратном пор дке, т. е. кулачкова  щайба поворачиваетс  в противоположном направлении и рычаг 6 устанавливает руко тку 10 в положение, соответствующее замкнутому состо нию контактов выключател  9. Цик.тThe winding of the heating element 8 of this spring is connected to the network by means of the switch 9. When the bimetallic spring is heated, it acts through the movable lever 6 on the ratchet 4 and the handle 10 of the switch 9. At the same time, the ratchet 4 turns the cam plate 2, and the handle 10 turns off the heating element 8 from the mains, which causes the cooling of the bimetallic spring. When the spring cools, the described process takes place in the reverse order, i.e. the cam plate is turned in the opposite direction and the lever 6 sets the handle 10 to the position corresponding to the closed state of the contacts of the switch 9.
