Abstract

  • 2.1 Ein hydraulischer Antrieb zur Betätigung des beweg­ lichen Kontaktstückes (15, 47) eines Hochspannungs­ schaltgerätes umfaßt eine Kolben-Zylinderanordnung (17, 49), deren Kolben (18, 50) mit dem beweglichen Schaltstück (15, 47) gekoppelt ist, außerdem eine Fluid-Speicheranordnung (19), aus der unter Druck stehendes Fluid dem Kolben (18, 50) zu dessen An­ trieb zuführbar ist, und schließlich eine Kompres­ soreinheit (33, 53) zur Aufladung der Fluid-Spei­ cheranordnung. 2.1 A hydraulic drive for actuating the mov union contact (15, 47) of a high voltage switching device comprises a piston-cylinder arrangement (17, 49), the pistons (18, 50) of which are movable Switch piece (15, 47) is coupled, also a Fluid storage assembly (19) from which under pressure standing fluid to the piston (18, 50) to its on driven is feedable, and finally a compress sensor unit (33, 53) for charging the fluid storage arrangement.
  • 2.2 Zur Vereinfachung und Verkleinerung des Antriebes sind die Antriebskolben-Zylinderanordnung (17, 49) und die Fluid-Speicheranordnung (19) räumlich nahe bei dem beweglichen Kontaktstück (15, 47) auf dem­ selben elektrischen Potential wie dieses befindlich angeordnet. Dabei liegt die Kompressoreinheit (33, 53) auf Erdpotential und die Leitungen, die die Kom­ pressoreinheit (33, 53) mit der Kolben-Zylinderan­ ordnung (17, 49) bzw. der Fluid-Speicheranordnung (19) verbinden, sind als elektrisch isolierende, druckfeste Leitungen ausgebildet. 2.2 To simplify and downsize the drive are the drive piston-cylinder arrangement (17, 49) and the fluid storage arrangement (19) spatially close in the movable contact piece (15, 47) on the same electrical potential as this arranged. The compressor unit (33, 53) to earth potential and the lines that the com pressor unit (33, 53) with the piston-cylinder order (17, 49) or the fluid storage arrangement (19) are electrically insulating, pressure-resistant lines formed.
  • 2.3 Der Antrieb findet Anwendung bei elektrischen Hoch- und Mittelspannungsschaltgeräten insbesondere bei SF₆-gasisolierten Trennschaltern. 2.3 The drive is used for electrical high and medium-voltage switching devices in particular SF₆ gas-insulated disconnectors.
