Definitions

  • the invention relates to a high-voltage circuit breaker with an on-resistance, which is connected in the course of the closing process via an auxiliary switching path in parallel with the main switching path and is switched off after its closing by opening the auxiliary switching path until the main switching path is switched on again, with a movable auxiliary switching pin of the auxiliary switching path which is spring-loaded in the opening direction and with a connecting rod articulated on this auxiliary switching pin, which is connected in an articulated manner to a rotatably mounted crank mechanism of the drive element.
  • crank pin is pivoted by the crank mechanism, which moves the connecting rod via a locking cam until this locking cam strikes a stationary trigger and releases the connecting rod for a return movement. N., ch the release runs the crank pin in an elongated hole arranged in the connecting rod, the length of which is adapted to the return path of the auxiliary switching pin.
  • the invention has for its object to provide a high-voltage circuit breaker of the type mentioned, the auxiliary switching path drive is simplified in construction. In particular, locking cams, ratchet lock or the like. be avoided.
  • crank mechanism has a link which forcibly guides the associated joint of the connecting rod, which consists of a part which is concentric with the rotary shaft of the crank mechanism and an adjoining rectilinear part which is upstream and bent upward in the direction of engagement.
  • the control of the auxiliary switching pin is effected by the backdrop, the timing of the auxiliary switching pin movement resulting from the design of the two backdrop parts and their relatively related lengths.
  • the spring loading of the auxiliary switching pin results in positive guidance with only one guide surface of the link.
  • the link has parallel guide surfaces for the crank bearing of the connecting rod. This results in a positive connection between the connecting rod and the crank mechanism.
  • the triggering of the return movement during the opening process of the circuit breaker is automatically effected by the backdrop. Nevertheless, it can be advantageous in some cases to assign a projection to the straight-line part of the setting, which acts on the connecting rod in the sense of triggering.
  • a particularly advantageous embodiment of the invention results if the link is provided with a hub which forms a stop and guide surface.
  • Figure 1 shows schematically a high-voltage circuit breaker with on-resistance.
  • FIGS. 2 to 6 show representations for the sequence of movements of the crank mechanism provided for controlling the starting resistor according to FIG. 1 on the basis of various positions during the switching on and off. _
  • a high-voltage circuit breaker with on-resistance with the parts necessary for understanding the invention is partly shown schematically in section, in which all parts not essential to explain the invention, such as Post insulators, base frame and hydraulic or pneumatic drive devices, which are omitted for the sake of simplicity.
  • the high-voltage circuit breaker contains a main switching path 1, which can be connected in parallel with a closing resistor 2 for damping switch-on overvoltages.
  • the switch-on resistor 2 is assigned an auxiliary switching path 3, which consists of a movable auxiliary switching pin 3a and a spring-loaded fixed contact 3b.
  • the auxiliary switching pin 3a is loaded by a spring 4 in the switch-off direction and is actuated via a connecting rod 5 by a crank mechanism 7 arranged on a rotary shaft 6.
  • the sequence of movements for the auxiliary switching pin 3a is controlled in such a way that the auxiliary switching path 3 closes in the course of the switch-on process before the main switching path 1 closes.
  • the series connection consisting of the on-resistance 2 and the auxiliary switching path 3 is bridged and thus rendered ineffective.
  • the auxiliary switching path 3 opens automatically after the main switching path 1 is closed. In this switch-off position The auxiliary switching path 3 remains until the main switching path 1 is switched on again.
  • the crank mechanism 7 has a link 10 comprising the joint 9 of the connecting rod 5 with parallel guide surfaces, which consists of a part 10a which is concentric with the rotary shaft 6 of the crank mechanism 7 and a subsequent rectilinear part 10b which is upstream and bent upward in the switch-on direction. If the drive for the auxiliary switching path 3, as shown in FIG. 2, is pivoted in the direction of the arrow 8, the connecting rod bearing (joint 9) arranged in part 10b of the link 10 and the associated connecting rod 5 are actuated in such a way that the auxiliary switching pin 3a is in the direction of the arrow 11 is moved.
  • the connecting rod bearing runs through part 10a to a damping cushion 13 provided at the end of the link.
  • the main switching path is switched on.
  • the crank mechanism 7 is moved in the direction of the arrow 14 together with the gear provided for this purpose, the hub 15 surrounding the rotary shaft 6 forming a stop and guide surface for the connecting rod 5.
  • the connecting rod bearing (joint 9) again reaches the bent part 10b and is ready for a restart.
  • the cushion pad 13 may be made of rubber or other suitable shock absorbing material.
