Abstract (en)
[origin: JPH05234469A] PURPOSE: To provide a more compact structure in compliance with requirements for an overvoltage. CONSTITUTION: An extra high voltage breaking chamber is provided which accommodates a main breaking chamber 1 containing an insulative casing 20 having a permanent contact, an arc contact and two closed registers. These closed registers are inserted by actuating a closed circuit switch 30 as a semimoving device for operating one register called a first register before operating the other register called a second register. An auxiliary chamber 2 equipped with the insulative casing 20 is attached in parallel with the main breaking chamber 1. The insulative casing 20 includes an open varistor 26 associated with the open circuit switch 30 having an open circuit delaying mechanism positioned in the inside of the casing 20.
Abstract (fr)
La présente invention concerne une chambre de coupure pour ultra haute tension comprenant une chambre principale (1) comportant une enveloppe isolante contenant des contacts permanents, des contacts d'arc et deux résistances de fermeture insérées par un dispositif semi-mobile dit interrupteur d'enclenchement mettant en fonction l'une des résistances, dite première résistance, avant l'autre, dite seconde résistance. Une chambre auxiliaire (2) est montée en parallèle de la chambre principale (1) et comprend une enveloppe isolante (20) contenant une varistance d'ouverture (26) associée à un interrupteur de déclenchement (30) présentant un mécanisme de retardement de l'ouverture situé à l'intérieur de l'enveloppe (20). <IMAGE>
