In an integrated type gas-insulated switching apparatus, a plurality of switching devices are provided. Each of switching devices includes a contact and an insulated container in which the contact is contained. The contact comprises electrodes adapted to be contacted with each other and separated therefrom. The insulated container is filled with an insulating gas. A conductive container is provided, to which the plurality of switching devices are connected, respectively. An insulated structure supports the conductive container.

The present invention provides a switchgear, which can achieve miniaturization and simplification while securing high operation reliability, and excellent in assembly, operability and inspection, and further, has a compact size. A fluid pressure operating section is provided in a mechanical box arranged on a lower end portion of a support porcelain tube. Insulated operating rods are received in the support porcelain tube, and connecting mechanisms are received in a container. Switching contacts of circuit breaker and disconnecting switches and the fluid pressure operating section are connected via the connecting mechanisms and the insulated operating rods.

Diese Hochspannungsschaltanlage ist mit Sammelschienen (14,18) und diese tragende Stützisolatoren (15,19) und Traggestellen (16,20) versehen, ferner mit einem mehrpoligen Schaltgerät, welches pro Pol mindestens eine Löschkammer (2,3) aufweist. Jeder Pol des Schaltgeräts ist mit einem separaten, auf Hochspannungspotential gelegenen Antrieb (6) versehen. Jeder Pol des Schaltgeräts für sich ist mit einem ihn tragenden Isolator (23) und mit Anschlussklemmen (12,13) der Hochspannungsschaltanlage verbindbar. Jeder Pol des Schaltgeräts ist separat auswechselbar und jeder Pol des Schaltgeräts ist um eine Achse (21) schwenkbar gelagert. Die Hochspannungsschaltanlage weist eine vergleichsweise hohe Verfügbarkeit auf und sie kann besonders preisgünstig erstellt werden.

A switch assembly for high-voltage electric power lines, comprising a supporting base, which is supported by one or more supporting posts, and operating means for actuating a line disconnection maneuver. The switch assembly also comprising on the supporting base and arranged in two lateral rows and a central row:

• six insulating supporting columns, equally divided along the two lateral rows;
• three circuit breakers with a column insulator, mutually aligned along the central row on a substantially vertical plane which is perpendicular to the supporting base, a two-blade disconnector being associated with each one of the circuit breakers, a first one of the blades having an end which is connected to the moving contact of the circuit breaker and a second one of the blades having an end which is connected to the fixed contacts of the circuit breaker, the circuit breaker and the two blades associated therewith being rotatable together about the vertical axis of the circuit breaker, for a possible line disconnection actuated by the actuation means; and
• instrument transformers.

@ A supporting insulator (9) to support the driving mechanism (6) of a disconnect switch part (100) and a supporting insulator (9) of a breaker (10) are unified. The heights of the fixed contact (4) and the driving mechanism (6) of the disconnect switch part (100) as well as the height of the upper end of the common supporting insulator (9) supporting the breaker (10) are substantially the same. Setting area is thus decreased, while ensuring a high spatial insulation distance.

L'invention est relative à un dispositif de commande par un arbre rotatif (28) des différents pôles (10, 12, 14) d'un disjoncteur électrique haute tension. L'arbre 28 est subdivisé en différents tronçons (30, 32, 34) s'étendant dans l'entraxe des pôles (10, 12, 14) et gainé par des tronçons de carter (46, 48) reliant d'une manière étanche les enceintes des différents pôles. L'arbre rotatif de commande (28) traverse d'une manière étanche le carter et est commandé par un organe de commande disposé à l'extérieur de ce carter.
