Definitions

  • the invention relates to a control mechanism for a high-voltage multi-pole electric switch or circuit breaker capable of occupying a first closed position, and a second position for opening the contacts, said mechanism comprising:
  • a toggle energy storage device composed of a cocking handle articulated by an axis to a telescopic guide for supporting a compression spring
  • a first control crank mounted on an arming shaft, and coupled by a transmission rod to a second control crank, which is wedged on an actuating shaft of the switch,
  • crank arm to cause the crossing of dead center of the toggle during the passage of the mechanism from the first position to the second position, and vice versa.
  • the documents FR-A- 2.500.222 and 2.613.123 disclose tumbler-type control mechanisms for a switch with three positions, one of which is a grounding position.
  • An auxiliary lock for locking the control crank is activated during the arming operation of the energy storage spring. This blocking function is essential so as not to disturb the state of the switch during compression of the spring.
  • These known mechanisms are relatively complicated by the presence of the auxiliary locking bolt.
  • the object of the invention is to provide a simple and reliable control mechanism for a high voltage switch or circuit breaker.
  • the mechanism according to the invention is characterized in that the cocking crank is mounted loosely on the cocking shaft by cooperating with stoppers for driving the first control crank, only opposite to the axis of the toggle joint, the telescopic guide of the spring bears on a crank pin located on the second control crank, to generate during the arming operation of the spring a temporary holding torque of the first and second cranks, which are kept in their initial state until the toggle joint breaks, and the control means for the cocking crank comprise a transmission mechanism controlled either automatically by a geared motor unit, or manually by a shaft coupled to an emergency control by a rod .
  • the transmission mechanism is connected to the gearmotor block by a kinematic link, arranged to authorize automatic operations by the gearmotor unit without reaction on the shaft of the emergency control, and conversely manual operation by the shaft of the emergency control without causing forced rotation of the output shaft of the geared motor unit.
  • a cam is mounted on the shaft of the emergency control unit intended to cooperate with a microswitch device to interrupt the electrical orders transmitted to the geared motor unit in the event of manual actuation of the rod of the emergency control unit.
  • This control mechanism is particularly suitable for a three-phase switch on the pole of an overhead electrical network.
  • Figure 1 shows a three-phase electrical device, in particular a switch 10 or a circuit breaker, mounted on a pole 12 of a high voltage overhead electrical network.
  • a system of spacers 14, 16 integral with the top of the post 12 serves as a support for two adjacent sections of line conductors 18R, 18S, 18T; 20R, 20S, 20T of the network, with maintenance of a predetermined inter-phase spacing.
  • the electrical isolation with the spacers 14, 16 and the pole 12 is provided by line insulators 22.
  • the pole 12 is at ground potential.
  • the transformer 26 is connected directly to two phases of the network, and is used for the power supply of a geared motor, and of the measurement and transmission electronics.
  • Each arrester 28 is equipped at its upper part with a connection terminal 30, connected respectively to a line conductor 18R, 18S, 18T; 20R, 20S, 20T corresponding from the network by an electrical connection cable 32, and to a connection terminal 34R, 34S, 34T; 36R, 36S, 36T of the switch 10 by a cable 38 provided with a plug-in socket.
  • the cutting or electrical continuity between the adjacent sections of the conductors 18R, 18S, 18T; 20R, 20S, 20T is provided by switch 10.
  • the main mechanism 40 for controlling the switch 10 is placed directly under the switch 10, and is controlled either automatically by an integrated gear motor, or manually by a rod 42 which can be operated from an emergency control 44 located at the bottom of the post 12.
  • the main mechanism 40 is provided with a double tumbler device 46 (FIGS. 2 to 4) housed between two fixed flanges 48, 50, and comprising a first control crank 52 articulated by a connecting rod 54 for transmission to a second crank 56 control wedged on the actuating shaft 58 of the switch 10.
  • the first crank 52 is mounted on an arming shaft 60 extending parallel to the actuating shaft 58 between the two flanges 48, 50.
  • the two axes 61, 62 of articulation of the connecting rod 54 on the cranks 52, 56 are eccentric relative to the corresponding shafts 60, 58.
  • the double tumbler device 46 is associated with a device energy accumulator 64 comprising a toggle 65 composed of a crank 66 for arming articulated by an axis 68 to a telescopic guide 70 for supporting a compression spring 72.
  • the cocking crank 66 is mounted coaxially proficient on the cocking shaft 60, and can cooperate with two tabs 74, 76 fixed on the first crank 52.
  • the telescopic guide 70 of the spring 72 bears on a crankpin 78 of the second control crank 56.
  • a first closure end stop 80 and a second opening end stop 82 cooperate respectively with stop surfaces 84, 86 of the first and second control cranks 52, 56, when the mechanism 40 actuates the 'switch 10 in closed and open positions.
  • the cocking crank 66 is controlled by a transmission mechanism 88 (fig. 5) capable of being driven, either by a geared motor unit 90 (fig. 7), or by an auxiliary crank 92 mounted on a maneuvering shaft 94 mechanically coupled to the rod 42 of the emergency control 44.
  • the actuating shaft 94 passes through orifices 95 formed in the flanges 48, 50.
  • the transmission mechanism 88 comprises a transmission crank 96 mounted coaxially idle on the shaft 94 of the manual emergency control 44.
  • the transmission crank 96 is provided with an oblong opening 98 centered on the shaft 94. Inside the opening 98 is housed a first drive pin 100 attached to the auxiliary crank 92.
  • the transmission crank 96 is articulated by a connecting rod 102 to a drive crank 104 having an oblong opening 106, inside which is housed a second lug 108 training.
  • the latter is fixed to a coupling crank 110 mounted on the cocking shaft 60, and coupled to the cocking crank 66.
  • the transmission mechanism 88 is coupled to the crank 66 for arming the double tumbler device 46 of FIG. 4, shown in the closed position of the switch 10.
  • the gearmotor block 90 comprises a motor and speed reducer assembly 112, the output shaft 114 of which is provided with a lug 116 capable of driving a control crank 118 mounted idle on the shaft 114 during a half-turn.
  • the crank 118 comprises two notches 120, 122 diametrically opposite and cooperating alternately with a locking pawl 124.
  • the output shaft 114 of the gear motor 90 always rotates in the same direction (represented in FIG. 7 by the opposite direction of the needles). a watch), for remote control operations at closing and opening.
  • the crank 118 is articulated to a transmission rod 126 having a coupling axis 128 capable of being introduced into an orifice 130 in the transmission crank 96.
  • FIG. 9 represents the mechanism 40 completely assembled, with housing of the output shaft 114 of the geared motor unit 90 in a notch 132 of the flanges 48, 50.
  • a cam 136 integral with the shaft 94 of the manual emergency control 44 cooperates with a microswitch device 138 to signal and interrupt the electrical orders sent to the geared motor unit 90 as soon as the emergency link 42 is operated from the remote control position to a manual control position (opening or closing).
  • FIG. 10 it can be seen that the terminals 36S, 36R, 36T on the left of the switch 10 are in electrical connection with the fixed contacts 140 of the three poles, and that the terminals 34S, 34R, 34T on the right are connected by a braid 142 to contacts mobiles 144 correspondents.
  • a lifting beam 146 is mounted for rotation about an axis 148 extending perpendicularly to the movable contacts 144, and is coupled to the shaft 58 for actuating the mechanism 40 by means of a coupling crank 149.
  • Each contact movable 144 in the form of a pin is coupled to a crank 150 of the spreader 146, so as to transform the rotational movement of the spreader 146 into a translational movement of the movable contact 144.
  • the spreader 146 passes through the sealed tank 152 of the switch 10 insulated with SF6, with interposition of a dynamic seal 154.
  • the operation of the mechanism 40 for controlling the switch 10 is as follows:
  • the closing operation of the switch 10 is effected by rotation of the arming crank 66 anticlockwise (see arrow F, fig. 3) via the transmission mechanism 88 actuated either manually by the shaft 94 of the emergency control 44, or automatically by remote control of the gearmotor block 90.
  • the displacement of the crank arm 66 causes progressive compression of the spring 72 on its telescopic guide 70, up to a maximum value located in the closing neutral shift position in fig. 3.
  • the action of the spring 72 on the second control crank 56 generates a holding torque which urges the crank 56 against the second stop 82 during the arming operation of the spring 72.
  • the switch 10 remains in its position opening during time arming, without the cranks 56, 52 are not positively locked by additional attachment means.
  • the closing and opening orders are sent directly to the geared motor unit 90.
  • Block tree 114 gearmotor 90 always rotates anti-clockwise for closing and opening operations.
  • the cam 136 integral with the shaft 94 causes the switching of the microswitch device 138 to interrupt the electrical orders transmitted to the gearmotor block 90, as soon as the rod 42 leaves the remote control position.
  • the crazy mounting on a half-turn of the crank 118 of the output of the geared motor block 90 allows the operation of the shaft 94 by the manual emergency control 44 without causing a forced rotation of the output shaft 114 of the motor assembly and speed reducer 112. This state is shown in FIG. 8, in which the output shaft 114 of the gearmotor block 90 is still in the closed position, while the transmission connecting rod 126 has been actuated towards the position of opening by the transmission crank 96, following a manual opening by the emergency control 44.
