Definitions

  • the present invention relates to a circuit breaker control, in particular for high and very high voltage circuit breakers.
  • circuit breakers for the operation of circuit breakers, and in particular for carrying out the so-called OFO cycle (opening, followed by rapid reclosing, followed by opening), controls of the mechanical (spring), pneumatic or hydraulic type.
  • a mechanical control is described for example in American patent n ° 4 240 300.
  • An object of the invention is to use a low power control already carried out and to adapt it to carry out a circuit breaker control of high power but very low cost price.
  • the subject of the invention is a control for the operation of a circuit breaker by the rotation of the main operating shaft, characterized in that it comprises a control of a pilot circuit breaker of power significantly lower than that required for the operation of said circuit breaker, associated to an assembly comprising a first trigger spring, a second engagement spring and a resetting motor, said springs being arranged to cause by their relaxation a 180 degree rotation of said main shaft, the relaxation of the springs being controlled by a movement of an output member of said pilot command.
  • the block referenced 1 shows diagrammatically a command for a circuit breaker of the conventional type, either mechanical, hydraulic or pneumatic, of known type.
  • this control has a much lower power than that which is necessary to actuate the circuit breaker to be operated.
  • This command serves as a pilot for a mechanism which will be described later and which is capable of storing and restoring the necessary energy.
  • the pilot control can perform a maneuver corresponding to the opening or tripping (0) of the circuit breaker, which takes the form of a rotation in the direction of the arrow f1 of a pilot shaft 2; an operation corresponding to the closing or latching (F) of the circuit breaker takes the form of a rotation of the shaft 2 in the opposite direction (arrow f2).
  • the pilot shaft is thus used to pilot a mechanism capable of supplying sufficient power for the operation of the circuit breaker considered.
  • the mechanism comprises a fixed frame 3 supporting a shaft 4 controlling the operating members, not shown of the circuit breaker.
  • a first arm 5 On the shaft 4 is fixed a first arm 5, one end of which serves as a point of attachment to a spring 6, said trigger spring by means of a rod 6A.
  • the arm 5 In the position of the figure, the arm 5 is in the high position and the spring is tensioned, having stored sufficient energy for triggering.
  • the arm 4 carries, by means of a ball bearing 7, a sleeve 8 secured to a toothed wheel 9.
  • a free-wheel type member 10, between the shaft 4 and the sleeve 8, allows the drive to the shaft 4 in the direction of the arrow F1 when the wheel 9 is driven in the same direction and prohibits all movements in the opposite direction of the shaft 4 and of the sleeve 8.
  • An arm 11 is integral with the sleeve wheel 9 and the sleeve 8.
  • a rod 12A to which is attached a first end of a spring 12, the other end of which is fixed to the base of the frame 3.
  • the arm 12 In the position of the figure, the arm 12 is in the high position and the spring 12 is tensioned, having stored sufficient energy to simultaneously ensure the circuit breaker is engaged and the trigger spring 5 is reset.
  • the toothed wheel 9 is connected by a chain 13 to a reset motor 14.
  • the wheel 9 rotates in the direction of the arrow F2, causing the arms 5 and 12 to rotate.
  • the arm 11 is provided with a roller stop 16 cooperating with a cam 17 (engagement stop) secured to the pilot shaft 2.
  • a fixed stop 18 prevents the arm from rotating in the direction opposite to the arrow F1.
  • the arm 5 carries a roller stop 20 cooperating with a lever 29 (trigger stop) forming part of a small mechanical assembly comprising a small lever 22 secured to the pilot shaft and articulated at 23 to a lever 24 articulated at 25 to a port 26 of a lever 27 having a fixed axis 28, and the lever 29 of fixed axis 30 articulated at 31 at one end of the lever 24.
  • a lever 29 trigger stop
  • the operation of the control is as follows: - when an order to open the circuit breaker is given by the network or line protection system in which the circuit breaker is inserted, the pilot control acts, which causes rotation of the shaft 2 in the direction of arrow f1.
  • the lever 22 pivots and drives the lever 24 which pulls the lever 29 which releases the stop 20.
  • the spring 6 relaxes, causing the arm 5 which rotates the shaft 4 by 180 degrees in the direction of the arrow F1, which causes the circuit breaker to open.
  • the pilot command then receives a closing order which causes the shaft to rotate in the direction of the arrow f2.
  • the cam 17 then pushes the roller stop 16 against the arm 11 which, passing its neutral position, is driven by the rebound of the spring 12.
  • the arm 11 rotates the shaft 4 in 180 degrees in the direction of the arrow F, which causes the circuit breaker to reset.
  • a stop 32 for example made of elastomer, absorbs the impact of the contact of the roller 20 with the lever 29.
  • the spring 12 To allow the resetting of the spring 6, the spring 12 must have a higher force.
  • the two arms 5 and 11 are then in the low position.
  • a rearming of the control is then carried out using the motor 14.
  • the latter causes the wheel 9 to rotate 180 degrees in the direction of the arrow F2, which produces the rearming of the spring 12 which comes into abutment on the abutment 18 and the 180 degree rotation of the shaft 4 which rotates the arm 5 by resetting the spring 6.
  • roller 20 abuts on lever 29 which has taken up the position of FIG. 2, because at the same time the pilot control 1 has been reset.
