Abstract: Использование: в коммутационной технике. Сущность: рабочее устройство для газовых прерывателей электросетей содержит рабочий поршень, вставляемый в рабочий цилиндр и выполненный с возможностью поступательного движения между первым и вторым положениями. Рабочий поршень делит внутренний объем рабочего цилиндра на первую и вторую камеры. Рабочий поршень движется из первого положения во второе во время операции отключения рабочего устройства, а в ходе операции закрытия рабочего устройства рабочий поршень движется из второго положения в первое. Выпускной патрубок рабочего цилиндра соединен с первой камерой, когда рабочий поршень находится вблизи второго положения, и выпускной патрубок соединен с второй камерой в случае, когда рабочий поршень находится на расстоянии от первого положения. Воздух под большим давлением подается в первую камеру в ходе операции отключения. Рабочее устройство содержит выпускной клапан для выпуска воздуха из первой камеры при падении давления в первой камере ниже заданного уровня. Выпускной клапан содержит элемент клапана с участком восприятия давления, на который действует давление из первой камеры.

Title: Method of use of part of energy dissipated at mechanical oscillation of apparatus structure
Inventor: SHAMASHKIN ALEKSANDR M
IPC: F03G7/00
Filed: 1991-12-24
Granted: 1995-04-20
Abstract: FIELD: power engineering. SUBSTANCE: replenishment of store of energy of the apparatus and suppression of parasitic oscillations in its structure are effected due to taking power off piezo and/or magnetostrictive elements arranged inside apparatus. Suppression of parasitic oscillations is effected on base of inverse piezo and/or magnetostrictive effect by tapping voltage off elements of parasitic mechanical oscillations acting on them in antiphase. Depending on degree of suppression of these oscillations and present situation, all elements of apparatus are divided into groups and its own threshold is set on each group. In case electric power taken off elements of group exceeds larger threshold, group is shifted to mode of suppression of oscillations and in case this power is less than lesser threshold, group is shifted to mode of replenishment of store of energy of apparatus.
