Definitions
- the invention relates to a circuit breaker a hollow for the discharge of hot switching gases, the Switching path limiting contact tube, whose from the Outlet opening facing away from the switching distance with a distance arranged, fixed deflector interacts.
- Such a circuit breaker is for example from the Publication DE 39 04 439 A1 or FR-A-2 760 890 known.
- a circuit breaker is for example from the Publication DE 39 04 439 A1 or FR-A-2 760 890 known.
- the contact tube is fixed arranged so that the distance between the outlet opening and the deflecting body always remains the same and therefore one constant deflected gas flow results.
- the Distance of the contact pieces limiting the switching distance during the switch-off process is made as large as possible.
- the known arrangement is an enlargement of the separation distance during the switch-off process only by an extended one Actuating stroke of the movable contact piece possible.
- the present invention is based on the object To design circuit breakers of the type mentioned at the beginning that the separation distance in the off position without extension the actuation stroke of the movable contact piece increased is, the removal of hot switching gases not is affected.
- the task is for a circuit breaker of the type mentioned Art solved according to the invention in that the contact tube is axially movable and the outlet opening in any position of the contact tube during the movement of surrounded by a fixed, nozzle-shaped flow straightener is.
- the flow straightener consists at least partially of an insulating material.
- Deflecting body at least partially from an insulating material consists.
- Figure 1 shows the schematic structure of an interrupter unit of a high-voltage circuit breaker.
- the switch-on position is shown below the line of symmetry, and the switch-off position of the interrupter unit is shown above the line of symmetry.
- the circuit breaker has a first and a second arcing contact piece 1, 2, which are surrounded by a first and a second nominal current contact piece 3, 4.
- the first arcing contact piece 1 is designed as a hollow contact tube. It has an inflow opening 5 at its first free end, while an outlet opening 6 is provided at its second free end.
- the drive of the circuit breaker is coupled by means of a switching rod 7, by the movement of which the first arcing contact 1 and the first rated current contact 3 are moved axially.
- an essentially hollow cylindrical flow straightener 8 Radially around the outlet opening 6 of the first arcing contact 1, an essentially hollow cylindrical flow straightener 8 is arranged in a stationary manner.
- a conical deflection body 9 is arranged opposite the opening 10 of the flow director 8.
- the drive-side part of the interrupter unit is enclosed by an outflow chamber 11.
- This outflow chamber 11 has outflow openings 12.
- the wall of the outflow chamber 11 consists of an electrically conductive material which serves to conduct the electrical current.
- the interrupter unit of the high-voltage circuit breaker is surrounded by a gas-tight encapsulation 13 which is filled with an insulating gas, in particular SF 6 .
- a first and a second are gas-tight due to the encapsulation 13 electrical connection 14, 15 and the shift rod 7 out.
- FIG. 2 shows a detail of the drive side of the interrupter unit shown, below the line of symmetry the position of the arrangement at the beginning of the switch-off process, above the line of symmetry the position at the end of the switch-off process is drawn.
- the arcing contact pieces 1, 2 are separated and ignited an arc 16 between them.
- This Arc 16 heats, expands and ionizes the quenching gas.
- the separating section is used flowed through additional extinguishing gas. The additional flow the separation path can be, for example, by a compression device 18 are generated.
- Extinguishing gas is partly through the inflow opening 5 of the first Free end of the first arcing contact 1 added and by the tubular design of the first arcing contact piece 1 inside the first arcing contact 1 dissipated.
- the outlet opening 6 the second free end of the first arcing contact 1 completely from the flow straightener 8 in the direction of the deflection device 9 towers.
- the hot switching gases 17 occur out of the outlet opening 6 and are by the flow straightener 8 directed in the direction of the deflecting body 9.
- On radial, swirling outflow is prevented.
- the first arcing contact piece becomes the course of the switch-off movement 1 moved in the direction of the fixed deflecting body 9.
- the outlet opening 6 of the second free end of the first arcing contact piece 1 also moves in Direction of the deflection body 9, while the stationary one Flow straightener 8 is not subjected to any movement.
