Definitions

  • the present invention relates to a device for operating a circuit breaker and more specifically to a device for operating a linear movement communicating, to the movable rod of the circuit breaker, an opening movement in one direction and a closing movement in the direction opposite.
  • An object of the invention is to provide an operating device making it possible to carry out a rapid OFO cycle (cycle comprising successively an opening of the circuit breaker, its closing and a second opening) followed, after a time delay (for example not less than 15 seconds ) a rapid FO cycle (cycle comprising closing of the circuit breaker followed by opening).
  • a disadvantage of the devices of the prior art is that the energy of the springs is transmitted from one spring to the other as well as to the operating member of the circuit breaker, by means of connecting rods articulated around shafts.
  • high voltage circuit breakers especially those with self-blowing require rapid movement of the contacts so that the opening and closing times of the contacts are as short as possible. It is therefore important that the operating device is placed as close as possible to the movable rod for transmitting the movement.
  • An object of the invention is to provide an operating device in which the energy transfers from one spring to another and from the springs to the movable rod are carried out without the interposition of rods, connecting rods or other movement transmission elements .
  • Another object of the invention is to provide an operating device in which the functions “energy accumulation” and “control” are physically separable, in particular so as to be able to control the operation of the circuit breakers remotely, without having to use members mechanical transmission of triggering and rapid engagement movements.
  • the subject of the invention is a device for operating circuit breakers, making it possible to carry out a rapid cycle of opening, closing and reopening of a circuit breaker (OFO cycle), the circuit breaker comprising a set of fixed contacts and a set of movable contacts, comprising an operating rod intended to be connected to said set of movable contacts, a first spring communicating when it relaxes, a movement of the rod in the direction corresponding to the opening of the circuit breaker, a second spring, of which the energy is at least twice that of the first spring and when it relaxes a movement of the rod in the direction corresponding to the closing of the circuit breaker, said device comprising means so that the relaxation of the second spring causes rearming the first spring, each of said springs being associated with a controllable locking member, characterized in that it comprises a first cylinder axially traversed by said tig e of operation, a second cylinder coaxial with said first cylinder, fixed with respect thereto, and containing inside it said first spring and a third

  • the movable assembly comprises contacts 9 and a nozzle 10 fixed to a compression cylinder 11.
  • the cylinder is connected to an operating rod 12 which passes through the partition 7 in leaktight manner.
  • This rod 12 is fixed to a rod 13 of the operating member of the invention, represented in FIG. 1 by a polygonal contour 14.
  • the operating member 14 is fixed to the chassis 2, therefore in the immediate vicinity of the operating rod 12 of the circuit breaker. Reference will now be made to FIG. 2 representing the operating member 14.
  • It comprises a cylindrical body 20, open at its lower end and closed, at its upper part, by a cover 20A provided with a central orifice traversed by the rod 13, connected, as we have seen previously, to the rod operation 12 of the mobile circuit breaker assembly.
  • the rod 13 passes through the bottom 21 of a fixed cylinder 22, coaxial with the cylinder 20 to which it is fixed by arms 23.
  • a spring 24 is disposed between the bottom 21 of the cylinder 22 and rests on a flange 13A of the rod 13. In Figure 2, the spring 24 is shown bandaged.
  • the rod 13 is in the high position (circuit breaker closed) and is maintained by means of a locking lever 30, of axis 31, bearing on a roller 13B at the end of the rod 13.
  • the locking lever 30 is itself even maintained in a fixed position by an angled hooking lever 34, with an axis 35 bearing on one side on a roller 32 of the lever 30 and on the other side on a core 36 of an electromagnetic coil 37.
  • the levers 30 and 34 are provided with return springs, referenced respectively 33 and 38.
  • the axes of the levers and the coil are integral with a plate 40 attached to cylinder 20.
  • a movable cylinder 50 coaxial with the cylinders 20 and 22.
  • the cylinder 50 can slide by means of a perforated flange 51 for the passage of the arms 23.
  • the cylinder 50 is notched, at its lower part 52, to allow passage of the lever 30, and carries an end roller 53.
  • a spring 54 is disposed between the cylinders 20 and 50; it is supported, at one end, on the collar 51 and, at the other end, on a fold 20B of the cylinder 20.
  • the spring is shown bandaged in Figure 2.
  • the cylinder 50 is kept fixed by means of a locking lever 60, of axis 61 and provided with a return spring 62 and a roller 63.
  • the locking lever is itself held in place by means of an angled lever attachment 65, axis 66, provided with a return spring 64 and cooperating, in the same manner as the lever 34, with an electromagnetic coil 68 having a core 69.
  • the rod 13 carries a hinge shaft 70 around which pivot levers such as 71 and 72, provided with end rollers 71A, 71B and 72A, 72B respectively.
  • a spring 73 tends to spread the levers. Stops 71C and 72C limit this spacing.
  • the operating device of the invention is completed by a rearming assembly comprising: a toothed wheel 80 with an axis 81 on which a chain 82 can be wound, fixed to the lower end 52 of the cylinder 50. - a ratchet wheel 83, of the same axis as the wheel 80 and idle on this axis, driven in rotation by a motor 84 driving an eccentric 85 and a ratchet system 86.
  • An attachment system can secure the wheels 80 and 83, it comprises a shaft 87 secured to the wheel 83, a roller 88 secured to the wheel 80, a fixed stop 89, and a bent lever articulated around the shaft 87 and comprising an arm 90 and an arm 91 provided with a light 92, a latching finger 93 and a return spring 94 linked to the wheel 83.
  • a lug 95 secured to the wheel 83 passes through the light 92; it serves to limit the stroke of the lever 90-91.
  • the motor 84 is supplied by a current source 100, by through a contactor having a fixed contact 98 and a movable contact 99.
  • the displacement of the contact 99 is obtained by virtue of an arm 96 secured to the end 52 and cooperating with a stop 97A of the contact-carrying rod 97.
  • the spring 54 is chosen to store an energy at least twice that of the spring 24.
  • the springs 24 and 54 are bandaged. In the event of a fault, an opening order is given by an electrical pulse from the coil 37; the core 38 of the latter moves and pushes the arm of the bent lever 34 which pivots. The roller 32 is released and the lever 30 pivots under the action of the roller 13 B.

  • the core 69 of the latter switches the lever 65 which releases the roller 63 from the lever 60 which switches under the action of the spring 62.
  • the roller 53 is released, allowing the spring 54 to relax, which drives the cylinder 50 upwards. .
  • the rod 13 follows the movement of the cylinder 50 thanks to the support of the rollers 71B and 72B on the shoulders 51A and 51B.
  • the arms 71 and 72 are tightened, by rolling the rollers 71A and 72B on the ramps 20D and 20E, the rollers 71B and 72B releasing the ramps 51A and 51B.
  • the device is ready to execute a second opening order, given by an electrical pulse to the coil 37.
  • the arm 96 At the end of the closing phase (FIG. 4), the arm 96 has driven the contact 99, thus closing the supply circuit of the motor 84.
  • the latter starts up and drives the wheel 83.
  • the finger 93 drives the stop 88, which causes the rotation of the wheel 80 and the movement of the chain 82.
  • the spring 54 is thus progressively bandaged.
  • the arm 90 At the end of compression of the spring, the arm 90 abuts on the stop 89, causing the bent lever 90-91 to rotate and the finger 93 to be released.
