Definitions

  • the present invention relates to an improvement made to ferro-magnetic voltage regulators in which the properties of ferro-resonance are used for the saturation of magnetic circuits and which are used in particular in inverters as well as in voltage stabilizing regulators and for which the properties of ferro-resonance with saturation of the magnetic circuit are used in the voltage regulation process.
  • such regulators consist essentially of a magnetic circuit associated with coils.
  • the regulators marketed to date give satisfaction from a simple functional point of view, but lead, for a given power and performance to heavy and bulky assemblies (therefore expensive), taking into account that the evacuation of the heat losses released both by the magnetic circuit only by the various windings which, to date, is produced simply by controlling the temperature of the ambient air surrounding the device, the heat exchange being carried out by simple natural conduction and convection.
  • the invention therefore relates to a ferro-magnetic voltage regulator in which the properties of ferro-resonance are used for the saturation of magnetic circuits and comprising a ferro-magnetic circuit associated with coils, and it is characterized in that said regulator is combined with an assembly allowing a forced extraction of the heat losses released both by the magnetic circuit and by the various windings, said forced extraction being obtained by action on the external surface of the components of said regulator by a forced air circulation directed against one regulator surfaces and flowing along other surfaces.
  • the single appended figure illustrates, diagrammatically, and in perspective an embodiment of a regulator according to the invention.
  • the regulator itself consists, conventionally, of a ferromagnetic circuit (1) associated with coils (2).
  • an assembly allowing the extraction of the thermal losses released both by the magnetic circuit (1) and by the coils (2), this assembly being designated by the general reference (3) and consisting essentially of a fan (4) disposed opposite the coils (2).
  • This fan (4) is mounted on a support (5) and its air flow is channeled, for example by means of a box (6) which extends from the support (5) to near the coils and this, so that the air flow acts on the entire surface of the regulator.
  • the air flow escapes on the one hand through the windings, and on the other hand and above all, laterally along the walls of the regulator.
  • the air flow will be a function of the power of the regulator, therefore of the calorific losses which occur, and will be adjusted to extract practically the greatest part of these losses despite a very limited heating of the system both on the peripheral surface '' inside coil and magnetic core.

Claims (2)

  1. Ferromagnetischer Spannungsregler, bei dem die Eigenschaften der Ferroresonanz zur Sättigung der Magnetkreise verwendbar sind und der einen an Wicklungen (2) gekoppelten ferromagnetischen Kreis (1) aufweist, dadurch gekennzeichnet, daß der Regler mit einer Einheit (3) verbunden ist, die ein erzwungenes Abführen der sowohl durch den Magnetkreis (1) als auch durch die verschiedenen Wicklungen (2) abgegebenen Wärmeverluste erlaubt, wobei das erzwungene Abführen durch Einwirken auf die Außenfläche der Bestandteile des Reglers durch eine erzwungene, gegen eine der Oberflächen des Reglers gerichteten und längs der anderen Oberflächen verlaufenden, erzwungenen Luftströmung erreicht ist.
  2. Regler nach Anspruch 1, dadurch gekennzeichnet, daß die Einheit (3) im wesentlichen durch einen gegenüber den Wicklungen (2) angebrachten Ventilator (4) gebildet ist, wobei der Ventilator (4) auf einen Träger (5) angebracht ist und dessen Luftstrom mittels eines Gehäuses (6), das sich zwischen dem Träger (5) bis in den Bereich der Wicklungen (2) erstreckt, so geführt ist, daß der Luftstrom auf die größtmögliche Oberfläche des Reglers einwirkt.
