Abstract
Двигательный привод прямого действия, осуществляющий операции включения и отключения вакуумного выключателя путем замыкания и размыкания контактов вакуумных дугогасительных камер, содержащий электродвигатель, приводящий в круговое вращательное движение, напрямую или через редуктор, кулачек в форме диска, который имеет участки с низким и высоким профилем, а также пружину отключения, механическую защелку и рычажный механизм, рычаги которого соединены с подвижными контактами вакуумных дугогасительных камер и с пружиной отключения, и который совершает качательные движения между включенным и отключенным положениями, при этом на одном из рычагов закреплен ролик, на который давит кулачек участком с высоким профилем при его вращении и выполнении операции включения, а рычажный механизм может удерживаться во включенном положении механической защелкой, причем, при операции включения осуществляется зарядка пружины отключения, а операция отключения происходит при срабатывании механической защелки и повороте рычажного механизма под действием разряжающейся пружины отключения в отключенное положение, отличающийся тем, что на боковой поверхности кулачка имеется выступ, а рычажный механизм имеет дополнительное плечо, которое при повороте во включенное положение взаимодействует с выступом и останавливает вращение кулачка в положении, когда его участок с низким профилем находится напротив ролика.Direct-drive motor drive that performs operations of turning on and off the vacuum circuit breaker by closing and opening the contacts of the vacuum interrupter chambers, containing an electric motor that rotates in a circular motion, directly or through a reducer, a cam in the form of a disk that has sections with a low and high profile, and also a tripping spring, a mechanical latch and a lever mechanism, the levers of which are connected to the movable contacts of the vacuum interrupter chambers and the tripping spring, and the latter makes swinging movements between the on and off positions, while on one of the levers there is a roller mounted on which the cam presses with a section with a high profile during its rotation and the inclusion operation, and the lever mechanism can be held in the engaged position by a mechanical latch, and, during the operation the switch-on spring is charged, and the switch-off operation occurs when the mechanical latch is activated and the lever mechanism is turned under the action of a discharging spring tions in the disconnected position, characterized in that on the side of the cam surface there is a projection, and the lever mechanism has a further arm, which, when turned to the on position interacts with the protrusion and stops rotation of the cam in a position where its low profile portion is located opposite the roller.
