Definitions

  • the present invention relates to a device for actuating an electrical appliance, in particular a disconnector or high earthing switch voltage.
  • It relates more precisely to a device for actuating an electrical appliance, in particular a disconnector or high earthing switch voltage, comprising in a control box a device for rotating the contacts of the high-voltage device and a control circuit comprising so-called limit switch contacts associated with device contacts.
  • High voltage disconnectors, as well as earthing switches are generally operated electrically thanks to an electric motor switched on from a local control cabinet and associated with a control circuit comprising contacts controlled by a position signaling circuit associated with the the device.
  • the order to open or close is sent from this cabinet and the engine is stopped by the pilot circuit contacts.
  • this electric motor actuator is fixed inside a housing command including a possible connection for a emergency crank in case of engine failure, sound supply or fault of the control voltage of the control contactors.
  • This mechanical connection ensures, when the crank is connected, disconnection electric motor.
  • the rotation speed of the crank cannot be imposed and can therefore be excessively slow or fast.
  • No guarantee of electrical performance disconnector cannot therefore be given, in particular during of a transfer operation in charge with positions at two busbars for example.
  • the contacts position indicators which must be in action positive for reliability reasons can open with contact separation speed too slow in the case of interruption of large currents of selfic nature.
  • contact separation speed is too slow, an arc requests these contacts for too long a time and the damages.
  • the complete closing maneuver or opening is not guaranteed and stopping the maneuver can be done by shock of mechanical stops possibly at full speed, which is detrimental to the good condition of contacts. This is particularly problematic in the case of shielded devices, i.e. in envelopes metallic, where the contacts are hidden and the operation must be done blind.
  • the invention proposes replace the crank with a portable electric motor autonomous power supply equipped with a connection arrangement mechanical with the rotary drive and provided with a device for electrical connection to the circuit steering.
  • said motor is housed in a housing of type drill housing and said connecting arrangement mechanical is a crank rod type rod intended for cooperate with the mechanical drive arrangement of the housing.
  • connection device electrical connector is intended to be plugged into the housing and ensuring the connection of a control circuit housed in the housing with said control circuit.
  • Said control circuit is preferably actuated via two push buttons and ensures rotation in one direction or the other direction of the motor.
  • the device may also include a connection to a locking relay intended to be connected to said audit connector and jumper to determine the direction of the operation intended to be connected to said connector.
  • it constitutes a emergency device actuation device electric in the event of a device malfunction normal actuation with a fixed electric motor associated with said housing.
  • said housing comprises a removable normal operating connector ensuring continuity of the driving circuit.
  • Figures 1A and 1B are schematic views in perspective and section of a control box of a electrical device according to the invention, in the position of normal running.
  • Figures 2A and 2B are schematic views in perspective and in section of the same control box, in intermediate position during a malfunction.
  • Figures 3A and 3B are schematic views in perspective and sectional view of the same control unit, to which is connected the emergency actuation device according to the invention.
  • Figure 4 is a schematic sectional view of the emergency actuation device connected to the ordered.
  • Figures 5 and 6 are electrical diagrams of a preferred embodiment.
  • control unit 2 shown in Figures 1A and 1B is known per se except for the connector arrangement removable as will be seen later.
  • This box 2 contains the actuator motor 40 fixed normal operation of the electrical appliance, provided a rotational drive device 15 for known manner at the connection of a backup crank. A switch 41 for disconnecting the motor 40 when switching on a crank is planned.
  • the order of operation is transmitted from the local control cabinet at motor 40 and contacts 5C, 6C are operated at the end opening or closing the device contacts for stop engine 40.
  • control circuit is sectioned and partly contained in a sealed connector 8 and removable via connections 42.
  • This connector 8 ensures, when mounted, the continuity of control circuit and connection of contacts 5C, 6C to the local control cabinet.
  • the actuation device is then put in place according to the invention as a backup device, as shown in Figures 3A and 3B.
  • This device comprises an electric motor 20 portable power supply 23 autonomous, preferably a battery, equipped with a mechanical connection arrangement 22 with the rotary drive device 15 and provided an electrical connection device 25 to the connections released 42.
  • the portable motor 20 is housed in a casing 21 of drill housing type and mechanical connection arrangement 22 is a rod linked to the rotor of the motor 20 and of rod type crank.
  • connection device 25 is a connector fitted of connections 43 intended to be plugged into the connections 42 released, some of these connections 43 being connected to the motor 20 by an associated control circuit 24 specified below.
  • Figure 4 shows the actuating device emergency connected to box 2.
  • the control circuit with its contacts 5C, 6C is then connected to the portable motor 20, its connections to the local control cabinet being interrupted.
  • the portable motor 20 is actuated by the circuit of control 24, in one direction to cause the opening of device contacts by pushing button 29, in the other direction to cause the closing of the contacts of the device by pressing button 30.
  • This actuation is piloted by the contacts 5C and 6C of the case, which ensure stopping the engine 20 once the appliance contacts high voltage totally open or totally closed.
  • Figures 5 and 6 are electrical diagrams of a preferred embodiment.
  • Figure 5 shows the installation in normal running. Electrically connected to the cabinet local control 1, control mechanism 2 contains the actuating motor 40 and the control circuit 4.
  • the motor 40 is driven in a direction corresponding to opening of device contacts by driver 5 and in the other direction corresponding to the closing of device contacts by conductor 6.
  • These conductors electric 5, 6 operate switches 5A, 5B, 6A, 6B mounted in a circuit known per se controlling the direction of rotation according to the conductor supplied.
  • these conductors 5, 6 are extended to form the driving circuit 4. To do this, they each have a contact 5C, 6C before being connected to the other terminal of the control cabinet 1.
  • the invention consists in equipping the housing 2 with a connector 8 which, in normal operating position, ensures the continuity of conductors 5 and 6.
  • the housing is equipped with connections 9 to 14, left open, once connector 8 is in place and whose function will be specified later.
  • the housing 2 is equipped with a mechanical drive arrangement 15 intended to produce actuation of the device contacts using a emergency device in the event of a malfunction of the 40 engine or equivalent.
  • the connector 8 is removed and the backup device is connected as shown in figure 6.
  • This emergency device comprises a motor 20 housed in a casing of the drill casing type, this motor 20 actuating a rod 22 of the crank rod type intended for cooperate with the mechanical drive arrangement 15.
  • This motor 20 is supplied by an autonomous source 23, preferably a battery, via a circuit 24 connected to a connector 25 inserted in the case in place of connector 8.
  • This control circuit 24 includes a set switches, two of which 25, 26 are closed under the effect a first push button 29 intended for opening and of which the other two 27, 28 are closed under the effect of a second push button 30 intended for closing.
  • This circuit 24 with parallel branches, of the same type as that motor 40, allows the reversal of the direction of rotation according to the button pressed.
  • the portable motor 20 is therefore controlled, so similar to motor 40, through contacts 5C and 6C of the control circuit 4. Once the device contacts fully closed or fully open, the portable motor 20 is stopped and the maneuver interrupted.
  • the locking relay 32 located in the cabinet local control 1 can be connected using connections 9 and 10 in series at the previous contact 5C or 6C. This relay provides security for authorization of the maneuver. This prohibits any false operation of the closing type with the power on or on.
  • Bridging 33 determines the direction of rotation opening or closing. Indeed, this meaning can vary according to control mechanism 2 and it is thus possible to equip the emergency device with two buttons pushers 29, 30 simply and directly indicating for the button 29 "to open” and for button 30 "to close". Bridging 33 can therefore be a continuous link or a direction reverser. The operator therefore does not have to worry about effective direction of rotation for closing or opening the device.
