Abstract

High voltage switchgear using arc extinction gas under pressure includes a Y shaped switch with a ribbed vertical column terminating in two ribbed switching chambers in V formation at the top. The vertical supporting column and the two chambers are filled with gas under pressure. At the base of the column is a hydraulic drive with a piston acting against two sliding rods controlling the switching members in the chambers above. Each rod slides inside a protective tube which is filled with the gas. Each tube has a straight insulated part inside the vertical column followed by a curved part inside the junction with the switching chambers, the latter part being of a resilient construction. At the termination inside the switching chamber each tube is connected to a sliding sealing member.

Description

Disjoncteur à gaz sous pression comprenant pour chaque phase deux chambres de coupure disposées en V.Pressurized gas circuit breaker comprising for each phase two interrupting chambers arranged in a V.

Dans la demande de brevet principal, la Demanderesse à décrit un disjoncteur à gaz sous pression comprenant pour chaque phase deux chambres de coupure disposées en V sur une structure reposant sur un support vertical isolant, ledit support vertical ainsi que les chambres de coupure étant remplis de gaz sous pression, un dispositif associé à chaque chambre servant à transmettre le mouvement entre un vérin de commande situé au pied du support et les contacts situés dans la chambre consi dégrée, caractérisé en ce que chaque dispositif comprend, d'une part, un tube de guidage étanche rempli de gaz sous pression comportant une partie droite isolante située à l'intérieur du support suivie d'une partie arquée disposée à l'intérieur de la structure et aboutissant à la chambre associée et, d'autre part, une bielle qui coulisse à l'intérieur du tube avec frottement doux dont une extrémité est reliée au vérin de commande et dont l'autre extrémité émerge à ltintérieur de la chambre associée, la partie de la bielle coulissant dans la partie arquée du tube étant souple, et en ce que chaque chambre est munie d'un sas d'étanchéité coulissant comprenant des moyens permettant d'assurer simultanément, d'un côté, ltétanchéité de la chambre et, de l'autre, l'étanchéité du tube, ledit sas comprenant deux parties séparables et alors respectivement solidaires de la chambre et du tube de guidage, ladite bielle comportant à l'intérieur du sas des moyens de désaccouplement en deux parties respectivement solidaires de la chambre et du tube de guidage associés. In the main patent application, the Applicant has described a pressurized gas circuit breaker comprising for each phase two interrupting chambers arranged in a V on a structure resting on a vertical insulating support, said vertical support as well as the interrupting chambers being filled with gas under pressure, a device associated with each chamber used to transmit the movement between a control cylinder located at the foot of the support and the contacts located in the chamber considered to be degree, characterized in that each device comprises, on the one hand, a tube sealing guide filled with pressurized gas comprising a straight insulating part located inside the support followed by an arcuate part disposed inside the structure and leading to the associated chamber and, on the other hand, a connecting rod which slides inside the tube with gentle friction, one end of which is connected to the control cylinder and the other end of which emerges inside the associated chamber, the pa rtie of the rod connecting in the arcuate part of the tube being flexible, and in that each chamber is provided with a sliding airlock comprising means making it possible simultaneously to ensure, on one side, the sealing of the chamber and, on the other, the tightness of the tube, said airlock comprising two separable parts and then respectively secured to the chamber and the guide tube, said connecting rod comprising inside the airlock means for uncoupling into two parts respectively secured to the chamber and associated guide tube.

Un but de la présente addition est de préciser un mode de réalisation de la partie souple de la bielle disposée dans le tube de guidage. An object of the present addition is to specify an embodiment of the flexible part of the connecting rod arranged in the guide tube.

Selon ce mode de réalisation, la partie souple de la bielle coulissant dans le tube de guidage est constituée par une chaine à galets, le tube de guidage ayant une section rectangulaire ou carrée, les galets s'appuyant sur deux faces opposées internes du tube. According to this embodiment, the flexible part of the rod sliding in the guide tube is constituted by a roller chain, the guide tube having a rectangular or square section, the rollers resting on two opposite internal faces of the tube.

Avantageusement, les axes de rotation des galets sont terminés par des bouts arrondis qui s'appuient sur les deux autres races internes du tube de guidage. Advantageously, the axes of rotation of the rollers are terminated by rounded ends which rest on the two other internal races of the guide tube.

Une telle réalisation permet notamment une bonne fiabilité du dis joncteur, un prix de revient plus faible, et autorise des rayons de courbure plus faibles de la partie arquée du tube de guidage. Such an embodiment allows in particular good reliability of the circuit breaker, a lower cost price, and allows smaller radii of curvature of the arcuate part of the guide tube.

D'autres particularités et avantages de l'invention ressortiront de la description donnée ci-après en référence au dessin annexé dans lequel
- la figure 1 est une vue partielle schématique en coupe d'un disjoncteur selon l'invention
- la figure 1A est une vue agrandie de la partie A de la figure 1.Other features and advantages of the invention will emerge from the description given below with reference to the attached drawing in which
- Figure 1 is a schematic partial sectional view of a circuit breaker according to the invention
- Figure 1A is an enlarged view of part A of Figure 1.

- la figure 2 est une vue en coupe selon la ligne II-II de la figure 1. - Figure 2 is a sectional view along line II-II of Figure 1.

- la figure 2A est une vue agrandie de la partie A de la figure 2. - Figure 2A is an enlarged view of part A of Figure 2.

Dans la figure 1, la référence 201 désigne un isolateur support en céramique ; une structure métallique 202 est placée sur le support ; à la structure sont fixée deux chambres de coupure 203 et 204, qui comprennent chacune des contacts fixes reliés à une prise extérieure et des contacts mobiles. In FIG. 1, the reference 201 designates a ceramic support insulator; a metal structure 202 is placed on the support; two interrupting chambers 203 and 204 are attached to the structure, which each include fixed contacts connected to an external socket and movable contacts.

Le mouvement des contacts mobiles est assurée par une bielle isolante 207 associée à des moyens de déplacement de type connu non repré sentés. Cette bielle, guidée dans l'isolateur par un tube isolant 208, est solidaire d'dn palonnier 209 coulissant dans un tube 210. The movement of the movable contacts is ensured by an insulating rod 207 associated with displacement means of known type not shown. This connecting rod, guided in the insulator by an insulating tube 208, is integral with a spreader 209 sliding in a tube 210.

Ce palonnier est fixé à deux bielles actionnant respectivement les contacts mobiles des chambres de coupure 203 et 204. Ces bielles comportent chacune une partie souple 213, 214 entre deux parties rigides, les unes 211 et 212 fixées au palonnier 209, les autres 215, 216 fixées aux contacts mobiles à l'intérieur des chambres de coupure. La partie souple est selon l'invention constituée d'une channe à galets. This lifter is fixed to two connecting rods respectively actuating the movable contacts of the breaking chambers 203 and 204. These connecting rods each comprise a flexible part 213, 214 between two rigid parts, some 211 and 212 fixed to the lifter 209, the others 215, 216 fixed to the movable contacts inside the switching chambers. The flexible part is according to the invention consisting of a roller track.

Les bielles sont guidées par des tubes respectivement 217 et 218 présentant une partie coudée entre deux parties rectilignes. Les tubes ont une section rectangulaire (ou carrée) de telle sorte que les galets 213A, 214A des chaines roulent sur l'une ou l'autre face opposées internes du tube 217 ou 218. The connecting rods are guided by tubes respectively 217 and 218 having a bent part between two rectilinear parts. The tubes have a rectangular (or square) section so that the rollers 213A, 214A of the chains roll on one or the other opposite internal face of the tube 217 or 218.

Les axes des galets sont reliés de manière connue par des pièces planes telles que 220 (figure 1A).  The axes of the rollers are connected in a known manner by flat parts such as 220 (FIG. 1A).

Les extrémités 213B, 2143 des axes des galets sont arrondis (préférentiellement hémisphériques) et peuvent prendre appui sur l'une ou l'autre des faces latérales du tube.  The ends 213B, 2143 of the axes of the rollers are rounded (preferably hemispherical) and can bear on one or the other of the lateral faces of the tube.

Les tubes 213 et 214 sont étanches et établissent une communication, pour le gaz isolant sous pression, entre les chambres de coupure 203, 204 et l'intérieur de la colonne isolante 201. The tubes 213 and 214 are sealed and establish communication, for the insulating gas under pressure, between the interrupting chambers 203, 204 and the interior of the insulating column 201.

L'invention s'applique également à un disjoncteur ayant trois chambres de coupure en série, comme indiqué dans la figure 8 de la demande principale. Il y a alors trois bielles guidées dans trois tubes, et reliées à un même palonnier actionnée par une tige isolante. The invention also applies to a circuit breaker having three interrupting chambers in series, as indicated in FIG. 8 of the main application. There are then three connecting rods guided in three tubes, and connected to the same lifting beam actuated by an insulating rod.

Le mode de réalisation qui vient d'être décrit présente l'avantage d'être peu onéreux, d'assurer un rendement maxiumal, d'autoriser un rayon de courbure plus faible du tube de guidage et de simplifier le mécanisme de commande du disjoncteur. The embodiment which has just been described has the advantage of being inexpensive, of ensuring maximum efficiency, of allowing a smaller radius of curvature of the guide tube and of simplifying the control mechanism of the circuit breaker.

Une telle solution permet d'avoir des chambres de coupure présentant entre elles un grand angle, et éventuellement ces deux chambres 203, 204 peuvent être horizontales, les parties arquées 217, 218 faisant un angle de 909, le tube peut être obtenu par cintrage ou être constitué d'une goulotte obtenue par fraisage avec couvercle servant de guidage latéral ; mais dans ce cas, un conduit souple enveloppe la goulotte et assure l'étanchéité vis-à-vis de la structure 202. Such a solution makes it possible to have interrupting chambers having a large angle between them, and possibly these two chambers 203, 204 can be horizontal, the arcuate parts 217, 218 making an angle of 909, the tube can be obtained by bending or consist of a chute obtained by milling with cover serving as lateral guidance; but in this case, a flexible conduit envelops the chute and ensures the seal vis-à-vis the structure 202.

On peut aussi utiliser le dispositif avec un angle de 900 dans le cas de poste sous enveloppe métallique remplie de gaz isolant sous pression ; les chambres de coupure, telles que 204 et 208, n'ont plus d'enveloppe isolante mais baignent dans le gaz isolant ; la structure 202 permet avec les tubes de transmettre ce mouvement aux deux chambres de coupure. L'isolateur 201 est alors remplacé par une traversée conique utilisée couramment dans ces postes sous enveloppe.  It is also possible to use the device with an angle of 900 in the case of a post in a metallic envelope filled with insulating gas under pressure; the interrupting chambers, such as 204 and 208, no longer have an insulating envelope but are immersed in the insulating gas; the structure 202 enables the tubes to transmit this movement to the two breaking chambers. The insulator 201 is then replaced by a conical bushing commonly used in these enveloped stations.
