Definitions

  • the invention relates to an electrical high-voltage circuit breaker with a self-generated quenching gas flow and with a compression device for blowing arcs, in which a pressure chamber which can be heated by the arc energy and is directly adjacent to the isolating section and has a compression space associated with the compression device. possibly valve-controlled, is connected, and in which the compression chamber is connected to a low-pressure chamber via a pressure relief valve having a movable valve plate on the one hand and a refill valve having a movable valve plate on the other hand.
  • the invention has for its object to simplify the assembly effort for the valve control in an electrical high-voltage circuit breaker of the type mentioned.
  • this is achieved in that the two valve plates of the valves arranged between the compression space and the low-pressure space as two directly adjacent concentric washers of different diameters with partial overlap are formed and combined into a single valve device.
  • the first of the ring disks with a smaller diameter is pressed on the side facing the low-pressure chamber under spring load against a stationary stop as a valve seat and lifts when a predetermined one is created in the compression chamber
  • the other of the ring disks with a larger diameter lies against the first ring disk as a rattling valve with its inner opening edge and lies with its outer edge against a stationary stop as a valve seat, such that this other ring disk moves when the compression device moves in the switch-on direction releases the passage cross section between the compression space and the low pressure space for refilling the compression space.
  • the spring loading of the first ring washer is advantageously adjustable.
  • the two annular disks can surround a switch rod which penetrates the compression space and the low pressure space and moves the compression device.
  • the high-voltage circuit breaker shown schematically in FIG. 1 has a fixed contact 1, which is in engagement with a movable contact 2. To separate the two contact pieces, contact piece 2 is moved in the direction of arrow 3. A pressure chamber 5 formed by a nozzle 4 for guiding the extinguishing gas flow is rigidly moved with the movable switching element and is delimited by a base 6 rigidly connected to the switching element 2. A movable part of the compression device and the cylinder 7 shown in FIG. 1 delimit a compression space 8 together with a piston crown 9, which is arranged in a stationary manner and delimits a low-pressure space 10 relative to the compression space 8.
  • the stationary piston head 9 has through openings for a pressure relief valve on the one hand and a refill valve on the other hand.
  • valve device 11 consists of two concentric annular disks 12, 13 lying directly against one another, which have different diameters and partially overlap one another in area A.
  • the annular disk 12 forms the valve disk for the pressure relief valve arranged between the compression space 8 and the low pressure space 10.
  • This first washer 12 has a smaller diameter than the other washer 13. It is on the side facing the low-pressure chamber 10 under the load of coil springs 14, which are distributed uniformly over the circumference. parts are arranged, pressed against a stationary stop 15 as a valve seat, and lifts off from the valve seat 15 when a predetermined excess pressure arises in the compression space 8.
  • the other ring disk 13 has a larger diameter and is designed as a so-called rattling valve. It lies with its inner opening edge 16 sealingly against the first ring disk 12 and lies with its outer edge 17 against a fixed stop 18 as a valve seat.
  • the springs 14 are pretensioned by screws 19, and the spring loading of the first ring disk 12 can be made adjustable by turning the screws 19.
  • the two annular disks 12, 13 surround the shift rod 20 which passes through the compression chamber 8 and the low-pressure chamber 10 and moves the compression device 7.

Abstract

Dans un disjoncteur de soufflage automatique muni d'un dispositif de compression, une chambre de compression chauffée par l'énergie de l'arc électrique est reliée à un espace de compression éventuellement par commande à soupapes. L'espace de compression est relié à l'espace de basse pression par l'intermédiaire d'une soupape de surpression et d'une soupape de recharge. Selon l'invention, les deux disques des soupapes disposés entre l'espace de compression (8) et l'espace de basse pression (10) sont conçues comme deux disques annulaires (12, 13) concentriques situés directement l'un contre l'autre et de diamètre différent, se recouvrant partiellement et regroupés pour ne former qu'un seul dispositif de soupapes.
