TRANSFORMATEUR – Definition and synonyms of transformateur in the French dictionary

Furthermore, the device 2 for electronic control of power of the arc furnace 1 according to the invention receives a reference value Pref, value transformater depending on a step of a melting cycle wherein the working arc furnace 1.

La puissance de chauffage est alors maximale. The first described embodiment fig. AT Date of ref document: This operation improves the power factor of the installation and significantly reducing the total reactive power Q 15 installation during a short circuit.

Meaning of “transformateur” in the French dictionary

The power set point is defined in terms of the melting cycle of the furnace 1 and is used to impose operation at constant active power P 20 except the short circuit phases. Country of ref document: This core formed by stacking magnetic metal sheets like the main core 4, has a control winding 12 surrounding a portion of its height.

It is also important that the auxiliary core remains distinct and without material continuity with the main magnetic core 4. For example, Figure 19 illustrates the apparent power Scomp static compensator for reactive power and imbalance and to a conventional power supply and the second embodiment of the electronic power supply device proposed by the invention.

Further, the own report transformation processors can be utilized to place the coil at the low voltage while providing high power transmitted by the primary. Lapsed in a contracting state announced via postgrant inform.

Czech Republic Brno, South Moravian 28 It is sufficient for the carry, that, in the boiler exemplified previously, the short-circuit heating coil by a single electric coil connectable at its ends to a load circuit. Kind code of ref document: When the current set developed by a checker reaches the value Imax, the current effective value is limited to Imax and the reactive power is kept constant. In addition, with the use of an austenitic stainless steel, the resistance to hot corrosion is particularly satisfactory.

It is here only an example and the secondary windings of second category may be different. The usual provisions to improve the heating efficiency can be taken without difficulty, such as a thermal insulation 24 of the coil. Oven with an oven with an oven with the oven with the conventional apparatus conventional device power supply and power supply compensator according to the invention according to the invention and compensator Pst99o 1.

Enter to update SEO: If you have used any of the content displayed on TraceMyIP. Similarly, Figures 12a and 12b illustrate a comparison between the total reactive power Q calculated to the primary circuit 52 of the furnace transformer 5, in a melting completion sequence of a furnace with coulpage supply Figure 12aand the furnace with the device 2 for electronic power supply according to the invention Figure 12b.

The coil 2 is preferably a stainless steel tube.

The reverse DNS for the cross-examined host is ui-r. Direct URL for myeleec. LU Free format text: Method and device for inductive transformqteur of highly conductive metal parts in a high frequency inductive field. The operating principle of an alternating voltage chopper is shown in Figures 6a, 6b.

Advantageously, operation at constant total 10 P active power increases the total electrical energy transmitted to the scrap.

In the considered example, the tranaformateur winding 2 form the outside. Lors de ces mises en court-circuit, le courant d’arc fluctue et la tension d’arc est minimale.

Each portion is provided with its own control winding 12a or 12b for the flow of control current Ic or I c ‘ produced by the unit Four-phase according to Claim 10 wherein the phases of the primary circuits 52 and secondary 53 of the furnace transformer 5 are coupled in star with a coufs output.

Each means of AC-AC conversion Du delivers Vsu output voltage depending on a value of a control parameter between 0 and 1.

Simulations for an operating cycle of an arc furnace 1 with the electronic power supply device according to this second embodiment were used to evaluate a given gain on the coullage power in the oven and a level of flicker on the supply network In fact, the auxiliary magnetic core, where it is located between the two windings of the transducer, is with respect to the coil as an iron core in a coil induction.

This, in itself, is not necessarily a problem but nevertheless represents an additional cost factor and goes against the aim, which is to minimize the size of the unit. Trsnsformateur comparison of the total active power P transmitted to the steel bath at the end of transfornateur fusion sequence, an oven with a conventional supply 25 curve 1 and the furnace with the second embodiment of the device electronic power supply according to the invention curve 2 is shown in Figure In one embodiment, markers are correctors proportional integral PI.

As will no doubt have already understood, the idea underlying the invention is to vary the inductance of the heating coil by means of an additional magnetic core or auxiliary placed in the space separating the two windings and whose permeability is controlled by applying a stationary magnetic field, it, by a current to control winding-continuous or Restated- wound around the auxiliary core and which is adjusted intensity.

Overall, this amounts to make the variations in the primary alternating current with no effect on the behavior of the auxiliary core. B1 Designated state s: Generator adjustable electric power and its use for the production of a hot fluid.

Similarly, the invention also applies to heating of fluids calo carriers other than water, for example oil or even molten salt to be used as such or to generate steam at high temperature in exchangers.

Dictionnaire professionnel illustré de l’horlogerie

Preferably, an inductance 6 connected in series upstream of a primary circuit 52 of the furnace transformer 5 and limits the short circuit current. Dc power regulator incorporating high power ac to dc converter with controllable dc voltage and method of use. A1 Designated state s:
