Description

Известные электромагнитные системы дл  быстродействующих выключателей содержат Я-образный магнитопровод, расположенный между его полюсами, отключающий электромагнит и вспомогательный магнитопровод, соедин ющий нейтральную зону Я-образного магнитопровода с нейтральной зоной  кор .The known electromagnetic systems for high-speed switches contain an I-shaped magnetic circuit, located between its poles, disconnecting the electromagnet, and an auxiliary magnetic circuit connecting the neutral zone of the I-shaped magnetic circuit to the neutral zone of the core.

Однако быстродействующие выключатели с такими электромагнитными системами не создают достаточно больщого т гового усили  при включении и сохранени  требуемого быстродействи  при отключении.However, high-speed switches with such electromagnetic systems do not create a sufficiently large pull force when switching on and maintaining the required speed when switching off.

Дл  устранени  этого недостатка располагают, на стержн х П-образного магнитопровода две обмотки, направление тока в одной из которых после включени  измен етс  на обратное.To eliminate this drawback, two windings are placed on the terminals of the U-shaped magnetic circuit, the direction of the current in one of which is reversed after switching on.

На чертеже дана принципиальна  схема предлагаемой электромагнитной системы.The drawing is a schematic diagram of the proposed electromagnetic system.

Электромагнитна  система содержит Я-образный магнитопровод 1, отключающий электромагнит 2, расположенный между полюсами магнитопровода /, и вспомогательный магнитопровод 3, соедин ющий нейтральную зону Я-образного магнитопровода с нейтральной зоной  кор  4.The electromagnetic system comprises an I-shaped magnetic circuit 1, a disconnecting electromagnet 2, located between the poles of the magnetic circuit /, and an auxiliary magnetic circuit 3, connecting the neutral zone of the I-shaped magnetic circuit to the neutral zone of core 4.

На стержн х Я-образного магнитопровода расположены две обмотки 5 и 6. Якорь 4 св зан рычагами 7 и 5 с контактными системами 9 и 10.Two windings 5 and 6 are located on the bars of an I-shaped magnetic circuit. Anchor 4 is connected by levers 7 and 5 to contact systems 9 and 10.

Нредлагаема  электромагнитна  система действует следующим образом .The proposed electromagnetic system operates as follows.

При включении быстродействующего выключател  обмотки 5 и 6 включаютс  в цепь тока управлени  таким образом, чтобы направление их магнитных полей было одинаковым. В этом случае магнитна  система превращаетс  в сдвоенный клапанный электромагнит, который позвол ет реализовать больщую силу прит жени   кор , при любой заданной величине его перемещени , и легко преодолеть усилие выключающей пружины //.When the high-speed switch is turned on, windings 5 and 6 are connected to the control current circuit in such a way that the direction of their magnetic fields is the same. In this case, the magnetic system turns into a double valve electromagnet, which allows realizing the great force of attraction of the core, at any given amount of its movement, and it is easy to overcome the force of the switching off spring //.
