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 assembly allowing this extraction of heat losses is constituted by a forced air circulation, directed against one of the surface of the regulator and flowing along the other surfaces.
- the single appended figure illustrates, schematically, 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 most of these losses in spite of a very limited heating of the system both on the peripheral surface and '' inside coil and magnetic core.
