Definitions
- the invention relates to a high-voltage circuit breaker with a contact system, with one through one Switch drive driven contact piece and with a Opposing contact piece, by means of transmission elements drivable mating contact piece, by some Transmission elements an auxiliary gear is formed and at which the contact piece with a first electrical connection of the high-voltage circuit breaker and the counter contact piece with a second electrical connection of the high-voltage circuit breaker electrically conductive via a current path connected is.
- Such a high voltage circuit breaker is for example known from European patent specification 0 313 813 B1.
- a contact piece by means of a switch drive drivable, especially during the switch-off process a pin-shaped counter contact piece to increase the contact separation speed is also drivable.
- there the movement of the driven contact piece via movement transmission elements or an auxiliary gear on the Mating contact piece transferred to this in a direction of movement to drive the contact piece in the opposite direction.
- a high-voltage circuit breaker also emerges from FR 2 491 675 in which a drivable contact piece and an opposite to this by means of an auxiliary transmission and movement transmission elements drivable mating contact piece is provided.
- a high-voltage circuit breaker is also known from EP 0 025 833 A1 known in which a contact piece and a Counter contact piece coupled together by means of a gear and can be driven in opposite directions when switched off.
- the present invention has for its object a High-voltage circuit breakers of the type mentioned at the beginning create its lifespan compared to the known switches is extended.
- the object is achieved in that a the current path electrically parallel parallel current path, the from the mating contact piece to the transmission elements the second connection of the high-voltage circuit breaker leads, is interrupted by an isolation point.
- the object is achieved in that at least one of the transmission elements to interrupt a parallel current path parallel to the current path between the Mating contact piece and the second connection of the high-voltage circuit breaker electrically insulated is.
- the state-of-the-art high-voltage circuit breakers have the property in common that the mating contact piece driven by an auxiliary transmission and transmission elements will, at least partially with stationary parts of the switch, for example for storage purposes are. For example, gears or levers must be pivoted be stored stationary.
- the motion transmission elements or the auxiliary transmission normally not to carry high currents, such as those occur in the event of a short circuit, are designed after a few operations by such an electrical Load the drive mechanism for the counter contact piece destroyed or at least damaged.
- the solution according to the invention prevents current from flowing of the main current path completely prevented, so that no damage to mechanical parts Current flow are possible.
- Magnetic force effects are also prevented, that result from parallel current paths through which current flows and for example the contact pressure for sliding contacts can have a negative impact by lifting contact fingers.
- An advantageous embodiment of the invention provides that the end of the counter-contact piece facing away from the contact piece, in the area where the point of attack of the transmission elements is made of an insulating material.
- a further advantageous embodiment of the invention provides before that at least one bearing or shaft of the auxiliary transmission consists at least partially of an insulating material.
- a sliding in a sliding guide pin Auxiliary gear consists at least partially of insulating material or that a sliding guide of the auxiliary gear from an insulating material consists.
- Figure 1 shows on the basis of Figure 2 of EP 0 313 813 B1 sections of the fixed continuous current contact 5 a High-voltage circuit breaker, in the axially from the left drivable continuous current contact piece 4 with the attached Insulating nozzle 8 and the axially driven contact piece 9 protrudes.
- the figure shows the in the lower half Switch-on position of the drivable continuous current contact piece 4 and in the top half the position of the isolation nozzle 8 in the off position. - In the on position surrounds the Isolierdüse 8 also the counter-driven counter-contact piece 7.
- the first connection is in this switch position 39 and the second terminal 40 of the switch with each other conductively connected.
- the connections (39.40) are in the Figure 1 represented symbolically.
- the transverse to the direction of thrust with a U-shaped Cross-section provided coupling rod 27 is arranged.
- the Coupling rod can also have an L- or T-shaped cross section have, each having a cross-sectional part of a slideway forms for guiding the coupling rod.
- the bottom 34 of the U-shaped cross section forms the slideway.
- Deviating from the known construction is according to FIG. 2 the coupling rod 27 guided in two bearing cheeks 31, the part of a housing 30 are.
- This housing is on a contact bridge 32 attached, which to the fixed continuous current contact piece 5 is fixed and the fixed part 33rd of a tubular sliding contact, in which the opposite drivable counter-contact piece 7 via contact blades is contacted.
- the mating contact piece 7 is on his end facing away from the arc switching path with one provided flat head 13 which in two of the bearing cheeks 31st formed slideways 35 of the housing 30 is guided.
- the flat-shaped head 13 is vertical to the coupling rod 27 extending slot 12 provided.
- a two-armed control lever 10 which is forked at one end and on its other end is provided with a pin 11.
- the Pin 11 engages in slot 12 on head 13.
- the forked side End has two prongs 16 and 17, one form mouth-like opening 18 into which the pin 28 of the Coupling rod 27 can engage.
- the two tines 16 and 17 are provided on the outside with a contact surface 19 or 20, with which the control lever 10 - depending on its position - For contact with the bottom 34 of the U-shaped cross-sectional profile the coupling rod 27 comes.
- Through stops 36 and 37 in the housing 30 ensures that the control lever 10 remains in the respective investment position.
- the two Investment positions represent end positions between which the control lever 10 moves under the action of the pin 28 becomes. So that the fork-like end here a rotational movement can execute about the axis 38, the coupling rod 27th in the bottom 34 of the U-shaped cross section with an elongated Provide slot 29.
- the head 13 can be made of an insulating material, for example made of glass fiber reinforced plastic, around the current path from this end of the mating contact piece 7 over the cheeks 31 and the shaft 38 to the housing 30 and Interrupt contact bridge 32. Can do the same also the shaft 38 and / or its bearing or the pin 28 Insulating material exist.
- Pins 28, bearing cheeks 31 and control lever 10 are as transmission elements Components of the auxiliary gearbox that drive the motion of the drivable contact piece 9 in an opposite Driving movement of the counter-contact piece 7 converts.
