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.
