Kind code of ref document: Similarly, Figures 18a and 18b illustrate a comparison between the total reactive power Q calculated to the primary circuit 52 of the furnace transformer 5, in a fusion sequence, a furnace with conventional supply Figure 18a and oven with the second embodiment of the electronic power supply device according to the invention Figure 18b.
High-voltage secondary power factor correction system and method for ac furnaces. Preferably, the auxiliary core is divided into two parts 10a and 10b each provided with its own control winding 12a and 12b in which the adjustable direct currents circulate together in opposite senses.
IT Free format text: A full callback for the researched reverse DNS query was captured as df-fb5. Active power, that is to say, the heating power of the secondary, is therefore minimal.
La puissance de chauffage est alors maximale. At the shorted circuit, the arc current fluctuates and the arc voltage is minimal. China Beijing, Beijing 58 It is here only triohase example and the secondary windings of second category may be different. 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 triphae to the invention and compensator Pst99o 1.
Le serpentin 2 est avantageusement un tube en acier inoxydable. 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. Hangzhou Alibaba Advertising Co.
Similar to the first embodiment of the feeder, the index value is such that flicker flicker phenomenon disturbs little the network. Czech Republic Brno, South Moravian 28 French words that begin with tr.
However, this e is advantageously much weaker dimensioning than a compensator associated with a furnace with a conventional diet, but substantially greater than that associated with a furnace with the first embodiment of the electronic power supply device.
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. This coil is of sufficient size to produce a magnetic field able to saturate the auxiliary magnetic core when the control current is set tripbase its maximum intensity Ic max.

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. 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.
This operation has the same disadvantages as an oven with a conventional power supply with power factor even more degraded. China Hangzhou, Zhejiang 27 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 conventional supply Figure 12aand the furnace with the device 2 for electronic power supply according to the invention Figure 12b.
The medium voltage grid is UM, for example a network obtained by lowering in a transformer 8, a high-voltage network UH power distribution. These parts are disposed symmetrically on either side of the primary winding 3 in the space 11 within the coil.

Advantageously, each value is tri;hase from a signal 5 of error between a representative current value of a measured arc current and a current reference Iref. For convenience, reference is made in the following only to the boiler, provided that whatever is said about it is as much about the invention in its broadest sense as an adjustable electrical power generator.
A domain name pointer is determined to be df-fb5. Keyword Density Word count: For example, Figure 13 illustrates an apparent power instantaneous Scomp level static compensator for reactive power imbalance couplafe 7 for a furnace with conventional supply curve 1 and the furnace device with two power electronic power curve 2.
The secondary circuit 53 of the furnace transformer 5 is connected via neutral n ‘in the bottom electrode Site et forum d’entraide Scolaire en electrotechniqu e 53 characters. The metal which is formed the coil is preferably stainless steel, or any teiphase metal having a high electrical resistivity.
Alternator designed for applying rapid repetitive pulses to an electromagnetic launcher. Moreover, it would help to tighten this time the power adjustment range and impose therefore increased accuracy, thus less easy on the value of the power in this range.
Each transducer is connected to a different phase U, V or W of a three phase power supply. Major disruptions are related to movements of the scrap inside the furnace. This core formed by stacking magnetic metal sheets like the main core 4, has a control winding 12 surrounding a portion of its height.
Moreover, during the collapse of scrap 12 inside the tank, short circuit and arc extinctions succeed.

Ces circuits are therefore equal in number to that of the auxiliary cores and each include a return 23a column 23b matched individually to its associated core using also individual yokes 22a 22b. Boilers of the type considered are designed as transformer whose secondary winding, being short-circuited, is constituted by a wound metal tube coil and traversed by the fluid chauffer.
It was in fact understood that the auxiliary core is still working saturation. Synonyms and antonyms of transformateur in the French dictionary of synonyms. The winding 3 inside, powered by the electricity distribution network symbolized by the unit 5, so here constitutes the primary winding.
