61 High voltage circuit breaker operating at low energy JP7032989 1989-03-22 JPH02148526A 1990-06-07 EDOMON CHIYURI; DOUNI DEYUFURUNE; MISHIERU PERE
PURPOSE: To avoid generation of a spark resulting from a secondary arc by limiting the maximum clearance between secondary contacts to a value lower than the maximum clearance between arc contacts, and completely stopping a spark when a circuit breaker is closed. CONSTITUTION: When a circuit breaker is opened, a movable part is driven by a tube 6, and when contacts are separated from each other, a spark 50 occurs between arc contacts 4B, 5A. Then, the internal pressure of a chamber 20 increases, a piston 22 is pressed to resist the action of a spring 24, and gas expands via openings 16, 23A to keep the internal pressure of the chamber at a constant small value. At the end point of the opening movement of the circuit breaker, a sphere 36 leaves a groove 39 and is placed in a groove 38, and the excess pressure of the chamber 20 is eliminated via an opening 23A. Therefore, the maximum clearance between secondary contacts is limited to a value lower than the maximum clearance between the arc contacts 4B, 5A. Also when a tube 5 is driven to close the circuit breaker, the contacts 30, 31 are kept equipotential by contact with members 48, 49 so as to make contact without generation of an arc.

62 Dielectric gas type high voltage circuit breaker used for blowing JP23973489 1989-09-14 JPH02121219A 1990-05-09 EDOMON TOURII; DOUNI DEYUFURUNE; MISHIERU PURE
PURPOSE: To perform an operation with little energy regardless of interrupting current value by providing an interrupting chamber having a blowing cylinder and a set of secondary contacts together with an interrupting chamber for placing a fixed assembly having a fixed essential contact and a fixed arc contact and a movable assembly having a movable essential contact and a movable arc contact. CONSTITUTION: When a circuit breaker is opened, a movable part is driven by a tube 6, and when the contact is broken, an arc 50 sparks between arc contacts 4B and 5A. The increase in internal pressure of a chamber 20 keeps a piston 14 laid under the action of a spring 17 making contact with a part 16 as it is. The internal pressure of the chamber 20 is contact and low, and any excessive pressure is eliminated by opening a valve 14A. A pressure reduction caused within a capacitive part 35 opens a valve 44 to keep the internal pressure of the capacitive parts 35. Thus, no air energy is lost by suction. The arc 60 sparking between contacts 30 and 31 stops the piston 15 simultaneously with the arc 50 so that it is not moved to a part 16A. Thus, a circuit breaker which required a small operating energy even in the interruption of a weak current can be provided. COPYRIGHT: (C)1990,JPO
63 Auto-pneumatic compressed gas breaker JP16786788 1988-07-07 JPS6431318A 1989-02-01 DEIITORITSUHI HOFUMAN
PURPOSE: To completely protect the gas gap of an opened circuit breaker from plasma cloud by separating an outside chamber from a chamber of inside arc contacts by a shielding cylinder, when a short-circuit current is interrupted, so as to be situated at the outside of a switching section at all positions and processes. CONSTITUTION: When a short-circuit current is interrupted, a shielding cylinder 21 completely separates the outside chamber 19 of outside contact pieces 4, 5 from the chamber of inside arc contacts 12, 13. Further, the repelling force between soft iron rings 23, 26 on the occurrence of a short circuit drastically accelerates the movable soft iron ring 23, together with the shielding cylinder to follow an insulating material nozzle 11 which is moved so as to separate. The shielding cylinder 21 moves and is brought into contact with an elastic cushion 27, arranged in the stepped part of the nozzle 11. Thus, the chamber filled with arc plasma is surrounded by the shielding cylinder 21 and separated from the outside chamber 19, for housing a cold gas which is not contaminated.

L'objet de la présente invention est de fournir une assistance de commande au piston de compression (6) d'un disjoncteur pour coupure en charge à gaz comprimé avec cylindre de compression commandé (3), grâce à l'effet magnétique du courant de rupture. Un élément cylindrique creux (12), fait d'un matériau ferromagnétique, enveloppant de manière concentrique un élément de contact stationnaire (2), est fixé au cylindre de compression (3). Ledit élément (12) comporte au moins une rainure (16) dans laquelle est guidée une tige de piston (7, 9) du piston de compression (6). Une partie (9) de ladite tige de piston (7, 9) est faite de matériau ferromagnétique. Aussitôt qu'une petite portion de cette partie pénètre dans une rainure (16), elle est attirée dans ladite rainure (16) grâce à l'effet magnétique du courant de rupture. Cela accélère le piston de compression (6) dans la direction opposée à celle du cylindre de compression (3). La pression maximale du gaz de coupage est donc ainsi atteinte plus rapidement que par le seul actionnement du cylindre de compression (3). Ladite invention concerne les disjoncteurs à piston à effet de soufflage, en particulier les disjoncteurs SF6.
