Definitions

  • the present invention relates to a controlled electrical power switch and a method for switching an electrical power circuit.
  • a power switch is called a switch intended to be placed on an electric power circuit.
  • Electromechanical switches are the oldest, but are still widely used. Their drawbacks are their size, which is a function of the electrical power transmitted by the line on which they are placed, and their wear due, inter alia, to breakdown phenomena when the circuit on which they are opened or closed. placed.
  • the objective of the invention is a controlled electrical switch which has neither the drawbacks of electromechanical switches, nor those of semiconductor switches.
  • the invention relates to an electrical switch intended to be placed on an electrical power circuit, closing and opening controlled by a control signal, comprising a semiconductor switch.
  • it also includes an electromechanical switch and a signal processor.
  • the electromechanical switch is connected in parallel to the semiconductor switch, and the signal processor receives the control signal and controls the semiconductor switch and the electromechanical switch.
  • the invention also relates to a method for switching an electrical power circuit comprising a semiconductor switch and an electromechanical switch connected in parallel.
  • the semiconductor switch when closing said switch, the semiconductor switch is first closed, then the electromechanical switch is closed; conversely, on opening, the electromechanical switch is first opened, then the semiconductor switch is open.
  • this switching method is applied to a circuit traversed by an alternating current, and the closing and the opening of the electromechanical switch are produced at a time when the value of the voltage of the circuit, at the terminals of the switch, is weak.
  • Switch 1 is placed between a load 2 and a main power circuit 3.
  • the switch 1 when the switch 1 is closed, the load 2 is energized, its power is produced from the main circuit or power circuit 3. On the contrary, when the switch 1 is open, the load 2 is disconnected from the main circuit 3.
  • the opening and closing of the switch 1 is advantageously produced remotely, for example by a signal circulating in the power circuit 3 on a carrier and demodulated by the modem 4.
  • a local command can also or alternatively be provided .
  • a signal processor 11 forming part of the switch 1 receives the signal from the modem 4 and controls the interrupt assembly 12 interposed between the main circuit 3, to which it is connected by the terminals 5 and 6 and the load 2.
  • Modem 4 is also connected to terminals 5 and 6, through which it receives the modulated signal from power circuit 3.
  • the signal processor 11 can also emit a signal indicating the open or closed state of the switch 1, or also indicating the execution of a command.
  • This signal is sent by the modem 4 through the power circuit 3.
  • a control unit connected by a second modem to the main circuit, dialogues with the signal processor 11.
  • the switch 1 is described in more detail in Figure 2 where we find, with the same numbering as in Figure 1, the terminals 5 and 6 of the main circuit, the modem 4, the signal processor 11, all 12 and load 2.
  • the interrupt assembly 12 comprises a semiconductor switch 121 and an electromechanical switch 122 each connected to terminals A and B and therefore connected in parallel.
  • the semiconductor switch is advantageously a triac, the trigger 123 of which is connected to a port 1, 124 of the signal processor 11.
  • This switch can also be an association of thyristors, or an association of components of the Isolation Gate Bipolar Transistor type.
  • the electromechanical switch 122 comprises a coil 126, the powering up of which controls the movement of the contact 125 which is capable of connecting the terminals 127 and 128.
  • This electromechanical switch 122 can also be bistable.
  • it includes a permanent magnet core and two coils.
  • the control of one or other of these coils determines the direction of magnetization of the core.
  • the electromechanical switch control terminal 129 is connected to port 2, 130 of the signal processor 11.
  • the modem 4 comprises a signal processor 41, an operational amplifier 42 and a transformer 43.
  • the primary of the transformer 43 is connected to the terminals 5 and 6 of the main current circuit, a capacitor 143 preventing the transmission of parasites.
  • the secondaries of the transformer are connected to the operational amplifier which is itself connected to the semiconductor 41, which addresses or receives the signals from the signal processor 11.
  • a power supply unit 13 connected to terminals 5 and 6, supplies the power necessary for the operation of the semiconductor 41, the operational amplifier 42 and the signal processor 11.
  • the modem 4 receives at T o a switch closing signal and transmits it to the signal processor 11, which first of all triggers the closing of the triac, which is carried out at T1.
  • the potential difference V B - V A then decreases considerably and is reduced to the drop voltage V c of the triac.
  • the signal processor 11 commands the closing of the electromechanical switch 122.
  • the switch is opened symmetrically on reception of the corresponding control order by the signal processor 11 via the modem 4.
  • the electromechanical switch 122 when it opens or closes, the electromechanical switch 122 is only subject to its terminals A and B at a potential difference equal to the drop voltage V c of the semiconductor switch. This therefore allows the use of a lightly dimensioned electromechanical switch and limits its wear.
  • the semiconductor switch 121 is crossed by the supply current of the load 2 only during the time periods between T1 and T2 on the one hand, and T3 and T4 on the other hand .
  • T2 and T1 on the one hand, T4 and T3 on the other hand are only separated by a very small time interval, for example corresponding to a few oscillations, when the voltage in the main circuit 3 is alternating.
  • a preferred embodiment which we will describe with reference to Figure 4, makes it possible to further reduce the stresses weighing on the electromechanical switch 122.
  • the voltage V V B - V A has the same shape and, in the periods of time separating T2 and T1 on the one hand, T3 and T4 on the other hand, it varies between + V c and - V c .
  • the signal processor 11 uses the result of its analysis, so as to trigger the opening and closing of the semiconductor switch 121 at instants T2 and T3 near an instant of zero crossing of the voltage V That is to say that the point T2, for example, is positioned between the times t'2 and t''2 corresponding to voltages V o and - V o , of absolute value much lower than the maximum voltage V c that may be present between terminals A and B, when the switch at semiconductor 121 is closed.
  • the electromechanical switch 122 changes state only when the voltage has its terminals at an absolute value at most equal to V o , that is to say very low.
  • This invention can be carried out with components of different origins.
  • the electromechanical switch 122 is advantageously a relay with mercury contacts.
  • the invention can be implemented under the following conditions.
  • V vs 1.2 V to 1.7 V V e ⁇ 100 mV
  • the time interval between T2 and T1 is equal to 100 to 200 ⁇ s.
  • the time interval between T3 and T4 is equal to 100 to 200 ⁇ s.
