Abstract

Изобретение относится к области машиностроения и может быть использовано в гидравлических приводах для силовых высоковольтных выключателей, преимущественно в приводах элегазовых выключателей. Целью настоящего изобретения является обеспечение длительной и непрерывной эксплуатации привода в любых климатических условиях. Гидравлический привод для силового высоковольтного выключателя, содержащий гидравлический цилиндр с поршнем и штоком, связанным с подвижным контактом выключателя, насосный агрегат, гидросистему с предохранительным клапаном, с реле максимального и реле минимального давления и накопитель энергии, причём предварительное давление газа в накопителе энергии принято равным минимальному рабочему давлению рабочей жидкости в гидросистеме при максимальной температуре эксплуатации, а объём корпуса накопителя энергии выбран с возможностью автоматической компенсации падения давления газа при снижении температуры эксплуатации, при этом насосный агрегат выполнен в виде насоса низкого давления и сдублированных мультипликаторов давления, каналы которых выведены на опорные фланцы и через стыковочный узел параллельно связаны с гидросистемой, а накопитель энергии состоит из газогидравлических аккумуляторов, установленных на запорных патрубках фланца гидравлического цилиндра и связанных с рабочей жидкостью через запорные вентили с возможностью отключения каждого из них так, что объём оставшихся аккумуляторов обеспечивает осуществление полного цикла аварийной защиты выключателя.The invention relates to the field of engineering and can be used in hydraulic drives for high-voltage power switches, mainly in the actuators of gas-insulated switches. The aim of the present invention is to provide long-term and continuous operation of the drive in any climatic conditions. A hydraulic drive for a high-voltage power switch containing a hydraulic cylinder with a piston and a rod connected to the moving contact of the switch, a pump unit, a hydraulic system with a safety valve, a maximum and minimum pressure relays and an energy store, the preliminary gas pressure in the energy store being set to the minimum the working pressure of the working fluid in the hydraulic system at the maximum operating temperature, and the volume of the energy storage case is selected with the ability to The automatic compensation of the gas pressure drop when the operating temperature decreases, while the pump unit is designed as a low pressure pump and duplicated pressure multipliers, whose channels are led out to the supporting flanges and are connected in parallel with the hydraulic system through the docking station, and the energy storage device consists of shut-off pipes of the flange of the hydraulic cylinder and associated with the working fluid through the shut-off valves with the ability to turn off each of them, h then the volume of the remaining batteries ensures the implementation of a full cycle of emergency protection circuit breaker.
