Definitions

  • the present invention refers to a switch device for electrical relays.
  • the invention concerns an electronic pilot circuit for electrical relays or for any other device working electromechanically for switching, i.e. in which a current or voltage signal causes a pair of electrical contacts of a commutator and/or switch to open or close.
  • the invention similarly extends to the pilot method of the relay or of any other electromechanical switching device of a similar type.
  • electrical relays consist of electromechanical switching devices, which use a flow of current flowing inside a coil, in order to command a pair of electrical contacts, by means of the electromagnetic force generated, suitable for opening or closing an actuator circuit of an electrical and/or electronic apparatus.
  • electromechanical relays are the components that absorb most of the electrical energy necessary for the operation of the apparatus.
  • the electromagnetic force generated by the movement of the electrical contacts of a relay depends firstly upon the intensity of current flowing in the coil (and, therefore, upon the voltage applied) and upon the inductance of the coil itself.
  • the applied voltage typically varies within a range of minimum and maximum values (lower and upper limit values) and around an average value, which substantially corresponds to the nominal operating value.
  • the lower limit value corresponds to a voltage value that ensures, within a certain margin of safety, that the electrical contacts of the relay are excited, whereas the upper limit value corresponds to a tension value such that the coil does not overheat by the Joule effect and such that there is not excessive absorption and consumption.
  • the purpose of the present invention is, therefore, to indicate a switch device for electrical relays that avoids the aforementioned drawbacks, i.e. to make a switch device for electrical relays that allows the average lifetime of relays to be substantially increased, when they are used for switching in electrical and/or electronic circuits.
  • Another purpose of the present invention is to indicate a switch device for electrical relays that allows the heating and/or overheating of the relay to be avoided.
  • a further purpose of the present invention is to make a switch device for electrical relays that can be mounted, analogously, in standardised relay housing guides, i.e. inside the relative component.
  • the last but not least purpose of the present invention is to indicate a switch device for electrical relays that allows the production costs of the relay to be reduced, thanks to the possibility of making components (relays) that are substantially smaller than the prior art, and in virtue of the substantial prolongation of the average electrical life of the aforementioned components.
  • the device according to the invention allows a relay to be switched at full charge (be it of the resistive or inductive type) without an electrical arc, in such a way substantially extending the average electrical life of the relay compared to the prior art.
  • the switch device object of the present invention can be commanded through a voltage signal (for example by means of an analogue or digital signal within the range 0-24 volts), through a serial command or else through a CAN-BUS input, and can be mounted within standardised DIN sockets or guides intended for containing electrical relays, just as it is possible to incorporate each auxiliary switch device within the respective relay.
  • a voltage signal for example by means of an analogue or digital signal within the range 0-24 volts
  • serial command or else through a CAN-BUS input can be mounted within standardised DIN sockets or guides intended for containing electrical relays, just as it is possible to incorporate each auxiliary switch device within the respective relay.
  • the electrical relay R is used to switch power between the sources S1, S2 with alternating voltage.
  • the relay R is commanded to switch between the electrical contacts R1 and R2 through an optoisolator OT, which receives a digital command D2, for example from a microprocessor.
  • the electrical contacts R1, R2 of the relay R are placed in short-circuit by means of a static electronic component (such as a transistor, an MOS, a TRIAC, etc.), which is commanded to run only in the very brief period of time during which switching takes place (from a few thousandths of a second before switching to a few thousandths of a second after it has finished - outside of such a range the electronic component is deenergised), so as to allow the contacts R1, R2 to open and/or close without a drop in voltage and current flowing between them.
  • a static electronic component such as a transistor, an MOS, a TRIAC, etc.
  • an MOS electronic component is preferably used, generically indicated with K in figure 1, which is able to short-circuit the contacts R1, R2 of the relay R, through the diode bridge D (the latter used solely to rectify the sinusoidal shape of the input signal).
  • the MOS electronic component, indicated with K, is furthermore commanded to run through the photorelay F, which receives a digital command D1 from a microprocessor at the moment when the switching of the relay R takes place (which, in the case of figure 1, takes place through the optoisolator OT, following the digital command D2).
  • Each relay R together with its auxiliary switching device (circuit assembly generically indicated with P in figure 1), can also be housed inside a standardised socket or guide (such as a DIN guide), as schematically illustrated in the attached figure 2.
  • a standardised socket or guide such as a DIN guide
  • connection socket can house different circuits P (each comprising a normal electrical relay R connected to its own auxiliary switching device, also arranged inside the socket), all commanded by one or more microprocessors M, according to requirements, to the input of which digital signals DS, analogue signals DA, serial data DT or CAN-BUS type input signals CB can in turn be sent (in the last case, the CAN-BUS input signals CB are sent to the microprocessor M by means of a suitable converter C).
  • This system is particularly useful and cost-effective, in the case in which it is necessary to house a battery of relays R produced normally, each with its own switch device connected, without having to make substantial modifications to the existing circuitry.
  • each electrical relay R already with the auxiliary switching device incorporated; in this case, the switch device according to the invention is inserted directly inside the relay R, so as to allow its power to be switched, through a command of one of the various input modes (digital input, analogue input, serial input, CAN-BUS input).
