Description
Опыт показывает, что применение гидравлического привода в электрических контакторах позвол ет просто осуществить малую скорость размыкани контактов и многократный разрыв на каждый полюс контактора .Experience has shown that the use of a hydraulic drive in electrical contactors simply allows a low opening speed of the contacts and a multiple discontinuity per contactor pole.
Однако дл полного использовани преимуществ малой скорости размыкани контактов и многократного разрыва электрической цепи на каждый полюс контактора необходимо, чтобы в контакторе обеспечивалась одновременность размыкани всех контактов и резкое изменение давлени на контакты при включении и отключении контактора.However, to take full advantage of the low speed of opening the contacts and repeatedly breaking the electrical circuit for each pole of the contactor, it is necessary that the contactor ensure simultaneous opening of all contacts and an abrupt change in pressure on the contacts when the contactor is turned on and off.
В соответствии с насто щим изобретением эта задача решаетс путем снабжени каждого подвижного контакта контактора отдельным поршнем при общем дл всего гидропривода распределителе жидкости.In accordance with the present invention, this task is accomplished by providing each movable contact of the contactor with a separate piston with a fluid distributor common to the entire hydraulic drive.
На чертеже, схематически изображающем предлагаемый электрический контактор с гидравлическим приводом, прин ты следующие обозначени :In the drawing, schematically depicting the proposed electric contactor with a hydraulic drive, the following notation is accepted:
/ - неподвижные контакты, 2 - подвижные контакты, 3 - дугогасительна камера, 4 - деталь,- несуща подвижные контакты, 5 - гибкие электрические соединени , 6 - изол торы, 7 - возвратные пружины , 5 - внещн оболочка гидропривода, .9 - порщни гидропривода , /( и У/ - входное и выходное отверсти гидропривода, 12 v. 13 - входное и выходное отверсти распределител рабочей жидкости, 14 - электромагнит дл привода распределител ./ - fixed contacts, 2 - moving contacts, 3 - arcing chamber, 4 - part, - supporting moving contacts, 5 - flexible electrical connections, 6 - insulators, 7 - return springs, 5 - external sheath of the hydraulic drive, .9 - vehicles hydraulic drive, / (and U / - inlet and outlet of the hydraulic drive, 12 v. 13 - inlet and outlet of the working fluid distributor, 14 - electromagnet for driving the distributor.
При включении контактора рабоча жидкость через отверсти 10 и 12 одновременно подаетс под все порщни 9 гидропривода, что ведет к замыканию цепи между неподвижными и подвижными контактами/и 2.When the contactor is switched on, the working fluid through the holes 10 and 12 is simultaneously supplied under all the actuator 9 of the hydraulic drive, which leads to the closing of the circuit between the fixed and moving contacts / and 2.
При отключении контактора открываютс отверсти // и 13, в результате чего давление под всеми поршн ми 9 одновременно начинает падать, что и обусловливает строго одновременное размыкание всех контактов контактора.When the contactor is disconnected, the holes // and 13 open, as a result of which the pressure under all pistons 9 simultaneously begins to fall, which causes a strictly simultaneous opening of all the contacts of the contactor.
