Description

подвижный контакт 3, соединенный с поршнем 4 при помощи штока 5.movable contact 3 connected to piston 4 by means of rod 5.

Поршень 4 перемеш;аетс  в цилн-ндре 6, сообш,аюш,емс  отверсти ми 7 с атмосферой. Диэлектрическа  жидкость заполн ет -камеру 1 и через отверстие 8 и колонку 9 посто нно действует на поршень 4. Герметизированное отделение 10 частично заполнено жидким диэлектриком 11. Средством, поддерживаюш,им жидкий диэлектрик под давлением,  вл етс  газова  «подушка 12.The piston 4 is mixed in cylindrical 6, coaxially, ayush, with openings 7 with the atmosphere. The dielectric liquid fills the chamber 1 and through the opening 8 and the column 9 constantly acts on the piston 4. The sealed compartment 10 is partially filled with a liquid dielectric 11. The means supported by a liquid dielectric under pressure is a gas cushion 12.

Средства замыкани  цепи выполнены гидравлическими и содержат включающий домкрат 13, воздействующий на подвижный контакт 3 через плунжерный порщень 14, поршень 4 и шток 5. На домкрат масло подаетс  или подвергаетс  продувке в зависимости от положени  управл ющего клапана Г5. Гидравлическа  цепь заканчиваетс  гидравлическим аккумул тором 16, который запитываетс  насосом 17. Масло находитс  в резервуаре 18.The chain closing means are hydraulic and contain an engaging jack 13 acting on the movable contact 3 through the piston piston 14, the piston 4 and the piston rod 5. Oil is supplied or jacked to the jack depending on the position of the G5 control valve. The hydraulic circuit is terminated by a hydraulic accumulator 16, which is powered by a pump 17. The oil is in a reservoir 18.

Работает выключатель следующим образом.The switch operates as follows.

Во включенном положении (см. фиг. 1) наход щеес  под давлением масло аккумул тора 16 действует на домкрат 13 и удержр вает подвижный контакт 3 прижатым к неподвижному контакту 2 до тех пор, пока управл ющий клапан 15 остаетс  в своем положении «Подача.In the on position (see Fig. 1), the pressurized oil of the accumulator 16 acts on the jack 13 and keeps the movable contact 3 pressed against the fixed contact 2 until the control valve 15 remains in its position "Feed."

При продувке включающего домкрата посредством регулировани  клапана 15 газо-ва  подушка 12 через жидкий диэлектрик 11 будет толкать разъединительный поршень 4 вниз и отсоединит подвижный контакт.When purging the on jack by adjusting the valve 15 of the gas, the airbag 12 through the dielectric fluid 11 will push the separator piston 4 down and disconnect the moving contact.

Варианты выключател , представленные на других чертежах хот  и имеют конструктивные различи  в выполнении и расположении некоторых элементов работают в основном аналогично выключателю, представленному на фиг. 1.The switch variants presented in other drawings, although having structural differences in the design and arrangement of some elements, operate basically similarly to the switch shown in FIG. one.
