Abstract

Изобретение относитс к электротехнике и может быть использовано дл приводов коммутационных аппаратов, например разъединителей. Цель состоит в повышении надежности и т гово-энергетических показателей . Устройство включает электродвигатель 1 с индуктором 2 и вторичным элементом 3, установленный со стороны неподвижного контакта 20 коммутационного аппарата 11. В закрытом положении подвижного контакта 21 вторичный элемент 3 вт нут в расточку индуктора 2. Хвостова часть вала 10 коммутационного аппарата 11 со стороны установки рычага 9 помещена в поддерживающий подшипник, а упоры 7 крайних положений размещены на валу 10 между его рамой 12 и рычагом 9. Конструкци снижает ударные нагрузки, исключает длительное пребывание вторичного элемента вне расточки в коммутационных аппаратах с нормально замкнутым подвижным контактом. 2 з.п. ф-лы. 7 ил. ел сThe invention relates to electrical engineering and can be used to drive switching devices, such as disconnectors. The goal is to increase reliability and talk energy performance. The device includes an electric motor 1 with an inductor 2 and a secondary element 3 mounted on the fixed contact side 20 of the switching device 11. In the closed position of the movable contact 21, the secondary element 3 is retracted into the bore of the inductor 2. The tail part of the shaft 10 of the switching device 11 from the mounting side of the lever 9 placed in a supporting bearing, and the stops 7 of the extreme positions are placed on the shaft 10 between its frame 12 and the lever 9. The structure reduces shock loads, eliminates the long stay of the secondary element e boring in switching devices with a normally closed moving contact. 2 hp f-ly. 7 il. ate with

Claims

Claim

1. A linear electric drive of a switching apparatus, comprising a linear electric motor mounted on a frame with an inductor on a hinged support and a secondary element connected by a lever to the shaft of a switching apparatus mounted on the same frame, end position sensors, their control elements, characterized in that, in order to increase the traction and energy characteristics and reliability, the engine is mounted on the frame with respect to the switching device as follows. that with the normally closed position of the switching device, the secondary motor element is pulled into the stator bore, the angle between the longitudinal axis of the secondary element and the longitudinal axis of the lever is in the range of 90-105 °, the tail of the shaft of the switching device is equipped with a support bearing mounted on the frame, the shaft of the switching device is equipped emphasis extreme positions. mounted on it between the frame of the switching apparatus and the lever, and the end position sensors are mounted on the frame connecting the linear motor and the switching apparatus.

2. The electric drive according to claim 1, characterized in that the lever is mounted on the shaft of the apparatus by a sliding nozzle and placed between the ridges restricting its circular motion.

3. The drive according to claim 1, characterized in that. that the transverse axis of the hinge support intersects the longitudinal axis of the secondary element.
