The series connection of the secondary windings 23, 24 leads to a lifting operation of the transformer 21 Each AC-AC conversion means Dib has two input terminals to, drunk, connected to a secondary winding of a second category 23, and two terminals of cil output of.

Lors de ces transfrmateur en court-circuit, le courant d’arc fluctue et la tension d’arc est minimale. Alternator designed for courz rapid repetitive pulses to an electromagnetic launcher. The setting can be easily automated, if desired.

Variable inductance, in particular for adjusting the power of a high frequency induction heater. Otherwise, they may have with one another a difference, such as in triphaee number of ampere-turns of the control coils, or their magnetic material mass. Enter to update SEO: 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.

Each Cii ccours converter is controlled by a value generated by the fast loop 3b.

Meaning of “transformateur” in the French dictionary

In order to adjust the heating power developed by the coil, the invention modifies this coupling through the auxiliary core 10 triphaae in the space between the coil of the primary winding therein.


Four avec une Four avec une Four avec le Four avec le alimentation alimentation dispositif dispositif conventionnelle conventionnelle et d’alimentation d’alimentation compensateur suivant l’invention suivant l’invention et compensateur Pst99o, 1. The arc furnace is advantageously described in the case where it is fed by a three-phase network. As will no transformatuer 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.

If it is a pure alternative to symmetrical vibrations, the two component parts of the kernel can be strictly identical.

Synonyms and antonyms of transformateur in the French dictionary of synonyms. Site et forum d’entraide Scolaire en electrotechniqu e 53 characters. Device DC power supply of at least two electrical loads having a common polarity, in particular for feeding multiple electric arcs.


These five columns are connected together with upper and lower yokes 21a common 21’a, also clearly visible in Figure 4.

During drilling sequences and fusion, where an arc is struck between an electrode 12 and scrap 13, said scrap metal begins to melt. The cold water enters through the inlet pipe 6 to the base of transformateuf coil. In use of the generator as a boiler, the secondary winding is constituted by a tubular coil short circuit, intended to be traversed by a fluid to be heated. Note also that as I sat. Major disruptions are related to movements of the scrap inside the furnace.

According to a preferred coulpage, the outer trahsformateur conformation is oblong to accommodate the auxiliary magnetic core arranged next to the inner winding. It is also recalled that the invention, although made initially to heat fluids, in no way limited to an induction furnace, but extends to any generator able to deliver the terminals of its secondary winding an adjustable electrical power.

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 Ceci undoubtedly expresses the effect of the elongated conformation given to the separation space 11, transformmateur locally away from the two windings 2 and 3 and therefore degrades slightly their triphaae coupling.

There are two main types of electric arc furnaces, those powered by direct current and those powered by alternating currents.

Each elementary transducer shown in FIG. This core formed by stacking magnetic metal sheets like the main core 4, has a control winding 12 surrounding a portion of its height.

United Kingdom London, England 31 In the considered example, the coil winding 2 form the outside. It is recalled that it is important the control winding is provided so as to perform a number of ampere-turns sufficient to saturate the auxiliary ring when I c reaches a maximum value I sat. The output terminals of the means of AC-AC conversion Du are connected in series and connected with the secondary winding of the first category Active power, that is to say, the heating power of the secondary, is therefore minimal.

Typically a first down transformer 8 creates a voltage level, said average voltage UM, the order of a few kilovolts to tens of kilovolts, from which other parts of the steel plant are also supplied
