Definitions

  • the invention relates to a high-voltage circuit breaker with a main switching point and with an auxiliary switching point which opens when switched off after the main switching point and is connected in series with a switching resistor.
  • Switching resistors can be provided both for switching on and for switching off. When switched on, these resistors limit overvoltages such as z. B. when switching on unloaded lines can occur. When switching off, they make it easier to switch off large outputs or can also serve to limit overvoltages that occur when switching off inductive loads, e.g. B. choke coils can be connected. If the switching resistor is used to switch off, the auxiliary switching point may only be opened after the arc at the main switching point has been extinguished, and thus the circuit completely to be interrupted. It is therefore important that the auxiliary switching point is not opened before the arc at the main switching point has gone out.
  • the invention has for its object to be as simple as possible, d. H. To create a purely mechanical control device for the auxiliary switching point. Despite the mechanical connection of the drive of the auxiliary switching point with that of the main switching point, however, the switch-off process of the main switching point should not be hindered; H. delayed or otherwise impaired.
  • the auxiliary switching point has a force accumulator which can be charged by the drive of the main switching point when switched on and has a latching device, which inevitably engages in the charged position of the force accumulator and can be unlocked when switched off depending on the position of the movable contact piece of the main switching point is.
  • the energy required to switch off the auxiliary switching point is therefore stored when the circuit breaker is switched on.
  • the drive of the main switching point only needs to apply the very low energy required to unlock the energy store of the auxiliary switching point. There is no delay in the switch-off movement of the main switching point.
  • the control device of the auxiliary switching point can comprise a lever which acts in an articulated manner on the movable switching element of the auxiliary switching point and is pivotally connected to a crank arm which can be pivoted by the one-way clutch, and the lever and the crank arm can be placed against a stationary stop in the switched-on position of the auxiliary switching point in the over-dead center position.
  • a helical compression spring is suitable as an energy store. This can be connected to the movable switching element of the auxiliary switching point directly or via intermediate elements.
  • a one-way clutch which is suitable for the purposes of the invention can comprise two stops for the crank arm mounted on the drive shaft and attached to the common drive shaft and spaced apart by the angle of rotation of the drive shaft when switching on and off.
  • the stops can expediently be formed by a disc provided with a cutout, which is fastened on the drive shaft.
  • Figures 1 to 6 show a common drive device for the main and auxiliary switching point of a high-voltage circuit breaker in different switching positions to illustrate the sequence of movements.
  • the main switch 1 comprises a movable pin-shaped contact 2 with a power supply 3 and a fixed contact 4. Details of this main switch are not shown because they are not required for understanding the invention and are otherwise generally known.
  • the auxiliary switching point 5 also has a pin-shaped, rectilinearly movable switching element 6 with a power supply 7 and a fixed switching element 10.
  • a switching resistor 11 is connected to the fixed switching element 10, which facilitates the switch-off process at the main switching point 1.
  • the connection point 12 between the fixed contact piece 4 of the main switching point 1 and the switching resistor 11 forms one connection point of the circuit breaker, while the other connection point can be provided on the transmission.
  • a common drive shaft 14 is provided, which in a manner not shown, for. B. can be rotated by a hydraulic drive such that the movable contact piece 2 is movable by means of a crank arm 15 seated on the drive shaft 14 and a rocking lever 16 from the switch-on position shown in FIG. 1 to the switch-off position shown in FIG. 5 and vice versa.
  • the common drive shaft 14 also carries a disc 17 which is provided with a cutout, as a result of which stop surfaces 20 and 21 are formed.
  • a crank arm 22, which is pivotably mounted on the drive shaft 14, can be carried by these stop surfaces.
  • a coupling rod 23 forms an articulated connection of the crank arm 22 with the movable contact piece 6 of the auxiliary switching point 5.
  • This carries an abutment 24 for a helical compression spring 25 which serves as an energy store and which is supported at its other end on a stationary abutment 26.
  • the energy storage spring 25 is tensioned in the switched-on position, the crank arm 22 and the coupling rod 23 resting with their joint 27 on a fixed stop 30 in the overtop position.
  • the energy storage spring 25 is thereby locked in the cocked position.
  • Now starts the switch-off process by rotating the drive shaft 14, the crank arm 15 and the disc 17 are rotated in the direction of arrow 31.
  • the switching pin 2 of the main switching point 1 is thereby moved in the same sense, so that the switching pin 2 comes out of engagement with the fixed switching piece 4.
  • the switching pin 6 of the auxiliary switching point 5 initially remains at rest because the stop surface 21 of the disk 17 moves away from the crank arm 22.
  • the starting position according to FIG. 1 is brought about again in that the drive shaft 14 is rotated in the opposite direction in the direction of the arrow 32, the switching pin 2 of the main switching point 1 by means of the crank arm 15 and the rocker arm 16 engaging with the fixed switching element 4 and the switching pin 6 of the auxiliary switching point 5 comes into engagement with the fixed contact piece 10.
  • the stop surface 21 of the disk 17 is effective, which rotates the crank arm 22 against the force of the energy storage spring 25 until the over-dead center position according to FIG. 1 is reached again and the articulation point 27 of the crank arm 22 and the coupling rod 23 abuts the stationary stop 30. Thereby the energy that is required for the mechanical switch-off movement and for the extinguishing device is stored.
  • the switching resistor 11 is to be used as a combined switch-on and switch-off resistor, it is only necessary to choose the position of the stop surface 21 so that a lead is produced which leads to the closing of the auxiliary switching point 5 in front of the main switching point 1.
