Definitions
- the invention relates to a high-voltage circuit breaker with a pair of opposite, in the off state arcing contact pieces delimiting a separation distance and a pair of coaxial with the arcing contacts arranged continuous current contact pieces, of which in each case at least one of the contact pieces from a drive side is drivable, as well as with one in the course of Switchable movement, a compression piston and one driven compression cylinder having compression device and one on the drive side of the compression piston arranged during the switching movement fixed heating volume.
- Such a high voltage circuit breaker is already known from DE-OS 41 03 119.
- the known switch are two arcing contacts coaxial with continuous current contacts surrounded and a fixed heating volume is provided, in which the heated by an arc during the switching process Extinguishing gas stored and for a subsequent blowing of the Arc can be provided.
- a mechanical compression device for the extinguishing gas provided that on the one hand at low currents when the arc is not sufficient to heat the extinguishing gas, provides sufficiently high extinguishing gas pressure and on the other hand at medium-sized currents, the blowing of the Arc supports.
- a major advantage of the known circuit breaker described before other known designs is that the heating volume and the components that limit it during the switching movement need not be accelerated.
- the compression cylinder the drivable continuous current contact carries on its outside that the compression piston so on the side of the circuit breaker facing the drive is arranged that the compression cylinder with the continuous current contact can be moved out of the separation distance and that the continuous current contacts from the arcing contacts gas-tight by a coaxially surrounding insulating body are separated.
- An advantageous embodiment of the invention provides that the compression piston is pierced by a check valve is only in the direction from the compression space to the Allows heating gas to flow through.
- the extinguishing gas compressed in the compression space can thus through the check valve into the boiler room while an overflow of pressurized extinguishing gas from the Boiler room in the compression room is not possible.
- an overflow of pressurized extinguishing gas from the Boiler room in the compression room is not possible.
- the extinguishing gas pressure in the compression chamber increases sharply so that it obstructs the opening movement or slowed down.
- a further advantageous embodiment of the invention provides before that the continuous current contact carried by the compression cylinder a field electrode for equalization when switched off of the electrical field in the area of the isolating section forms.
- the fixed counter contact to the moving continuous current contact can also be designed as a field electrode. It is also conceivable on the opposite side of the drive of the switch A well-known, retractable side Arrange field electrode in the axial direction of the Switch is loaded with a spring force when switching on the switch can be pushed back by the compression cylinder and when switching off the compression cylinder up to a stop and stand there as a field electrode remains.
- FIG. 1 shows schematically part of an interrupter unit a circuit breaker without the housing, and in the upper half in the off state and in the lower half Half in the on state.
- each other two arcing contacts 1, 2 in the off state opposite the upper half of the figure coaxially.
- d. H. in the lower part of the figure is the drivable Arc contact 1 moved into the fixed counter contact 2.
- the drivable is also in the switched-on state Continuous current contact 3 in contact with the fixed one Continuous current contact 4 brought.
- the drivable continuous current contact 3 consists of an electrically conductive, metallic Coating on the outside of the compression cylinder 5, the the drivable part of a mechanical compression device forms for the extinguishing gas.
- This boiler room 11 is fixed and moves not when the switch is actuated. In the boiler room, the Heat of the arc provided expanded quenching gas, to extinguish the arc at zero current the gas channel 9 flows back to the arc chamber 8.
- the compression cylinder 5 is via a linkage 13 connected to the drivable arcing contact 1 and is driven with this.
- the compression cylinder can also be made entirely of metal, for example aluminum consist.
- the heating room 11 is so far away from the arc room 8 to the drive side moved that the compression cylinder 5th during the switch-off movement up to the fixed compression piston 6 be moved back and forth from the separation distance can.
- the electrically conductive coating 3 of the compression cylinder 5 is up to the end face of the compression cylinder 5 pulled and forms a field electrode in the off state to equalize the electric field between the Arc contacts or the continuous current contacts.
- the insulating material nozzle 10, which has the gas flow channel 9, is fixed in the area of the separating section and separates the area of the arc room 8 from the outside the interrupter unit, which in turn, for example, from included a porcelain housing, not shown becomes. There is only hot extinguishing gas through the gas flow channel 9 passed into the heating volume 11.
