Abstract
1. Переключающее устройство для воздушного выключателя, содержащее: ! неподвижный контакт, соединенный с источником питания основной цепи или цепи нагрузки для каждой фазы и предусмотренный согласно каждой фазе; ! подвижный контакт, расположенный в соответствии с неподвижным контактом и перемещаемый в положение замыкания для взаимодействия с неподвижным контактом или положение размыкания для отделения от неподвижного контакта; ! ведущий вал, выполненный вращаемым, для обеспечения движущей силы, чтобы передвигать подвижный контакт в положение замыкания или положение размыкания; ! рычаг ведущего вала, соосно расположенный на ведущем вале, один конец которого соединен с подвижным контактом; ! закрывающая пружина для обеспечения движущей энергии, чтобы передвигать подвижный контакт в положение замыкания; ! приводной рычаг, соединенный с закрывающей пружиной и вращаемый с помощью движущей силы, обеспечиваемой от закрывающей пружины; ! первый рычаг, выполненный вращаемым, один конец которого соединен с приводным рычагом для зацепления с ним; ! второй рычаг, вращаемый с помощью соединения с первым рычагом, имеющим две пластинчатых части, и имеющий удлиненную часть по отношению к первому рычагу для предотвращения задевания первым рычагом с помощью расположения первого рычага между двумя пластинчатыми частями; и ! третий рычаг, один конец которого соединен со вторым рычагом, а другой конец соединен с рычагом ведущего вала и вращается вместе со вторым рычагом для перемещения подвижного контакта в положение замыкания для вращения рычага ведущего вала. ! 2. Рычаги коленно-рычажного механизма переключающего устройс�1. A switching device for an air circuit breaker, comprising:! a fixed contact connected to the power supply of the main circuit or the load circuit for each phase and provided according to each phase; ! a movable contact located in correspondence with the stationary contact and movable to a closed position to interact with the stationary contact or an opening position to separate from the stationary contact; ! a drive shaft rotatable to provide a driving force to move the movable contact to a closed position or an open position; ! a drive shaft lever coaxially located on the drive shaft, one end of which is connected to a movable contact; ! a closing spring for providing driving energy to move the movable contact to a closed position; ! a drive arm connected to the closing spring and rotated by a driving force provided from the closing spring; ! a first arm that is rotatable, one end of which is connected to a drive arm for engaging therewith; ! a second arm rotatable by being coupled to a first arm having two plate portions and having an elongated portion with respect to the first arm to prevent the first arm from being caught by positioning the first arm between the two plate portions; and ! a third arm, one end of which is connected to the second arm and the other end of which is connected to the drive shaft arm and rotates with the second arm to move the movable contact to a closed position to rotate the drive shaft arm. ! 2. Levers of the toggle mechanism of the shifting device
