Title (EN) COMBINED CURRENT AND VOLTAGE TRANSFORMERS FOR A HIGH VOLTAGE INSTALLATION ENCLOSED IN A METAL ENVELOPE FILLED WITH PRESSURE GAS
(FR) TRANSFORMATEURS DE COURANT ET DE TENSION COMBINES POUR UNE INSTALLATION DE HAUTE TENSION ENFERMEE DANS UNE ENVELOPPE METALLIQUE REMPLIE DE GAZ SOUS PRESSION
Abstract: front page image
(EN)In order to avoid taking leads through the envelope (1, 2) the electrode of the voltage transforming capacitive part comprises an intermediate piece (3) insulated and tight to the pressure gas, inserted in the envelope. This piece comprises, outwardly, an insulating material coating (9) and a metal layer (10) on said coating. The three (3, 9, 10) form a support for the current transforming cores (11) wound with the secondary winding. The low voltage between the intermediate piece (3) and the metal layer (10) is led by an armoured measuring able (12/12a) of an electronic measuring amplifier (14). The current transforming cores (11) are mechanically protected by a cylindrical screen which, at the same time, leads the envelope currents.
(FR)Pour eviter de faire passer des cables de connexion a travers l"enveloppe (1, 2), l"electrode de la partie capacitive transformatrice de tension est constituee par une piece intermediaire (3), isolee et etanche au gaz sous pression, inseree dans l"enveloppe. Cette piece comporte, a l"exterieur, un revetement (9) en materiau isolant et sur celui-ci une couche metallique (10). Le tout (3, 9, 10) constitue un support pour les noyaux transformateurs de courant (11) entoures de l"enroulement secondaire. La basse tension entre la piece intermediaire (3) et la couche metallique (10) est amenee par un cable sure blinde (12/12a) d"un amplificateur de mesure electronique (14). Les noyaux transformateurs de courant (11) sont proteges mecaniquement par un ecran cylindrique qui en meme temps conduit des courants d"enveloppe.
