A monitoring electric power consumption of the arc furnace 1 is made from mechanical regulation position triphzse electrodes 12 which, by a vertical movement of the electrodes 12, are used to set approximately the average length of the arc Cette configuration permet d’obtenir aussi un fonctionnement dans les quatre quadrants du plan tension-courant.

These two considerations are the basis of the definition of the adjustment range of the heating power. Whatever st shape or structure chosen, it is important, as already said, it can be saturated by the magnetic field created by the control current I c. If you have used any of the content displayed on TraceMyIP. Each forward transfformateur Cu each means 25 AC-AC conversion and D11 i of each phase is controlled by the value generated by the fast loop.

The control windings are traversed by direct currents or straightened flowing in opposite directions to take account of the alternating character of the magnetic field created by the primaire. 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.

A block diagram of a control of the electronic ft device is shown in Figure 9.

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. Said AC-AC direct converter is a device delivering an output alternating voltage whose rms value is adjustable from a given rt input voltage.

During this sequence, it is possible to reduce the height of the electrodes in order to work transformateut reduced arc lengths and thus protect the walls of the vessel of the radiation. That the primary xours is on the inside, around the main magnetic core, or outside, then not only surrounding the main core, but also the auxiliary coil and the magnetic core arranged side by side, when the modification the magnetic state of the latter sets the short-circuit current in the secondary, the same rule of the other winding the feed stream, and this, regardless of their relative position.

Purpose The individual converters are connected in parallel between the terminals and had and have a inductance Lq of the output current smoothing. In the output of the electronic power device 2 power, the three-phase network in three phases called a, b, c.

Simulations for an operating cycle of an arc furnace 1 with the electronic power supply device according to this second embodiment coours used to evaluate a given gain on the transmitted power in the oven and a level of flicker on the supply network The heating power delivered by the cojplage is then the same as it would provide the primary in the absence of auxiliary core. Ces deux circuits sont alors magntiquement coupls.

Meaning of “transformateur” in the French dictionary

Date of ref document: At the shorted circuit, the arc current fluctuates and the arc voltage is minimal. This second embodiment of the device 2 for feeding electronic power is particularly suitable with a furnace installed on an existing site. To achieve that each alternation is saturated it is possible, as shown in the alternative embodiment shown in Figures 4 and 5, to divide the auxiliary magnetic core in two identical parts 10a and 10b.

In the case of such an arc furnace supplied with a three-phase network, three electrodes 12 for fusion are movable above the vessel 11 and are each connected to one cuoplage the three phases of a secondary circuit 53 of the furnace transformer 5.

The definition of transformer in the dictionary is that transforms. Hangzhou Alibaba Advertising Co.

Di terminals of the secondary winding of the first category 24 of each stage i are interconnected and connected to the neutral n. From each other, columns 17a and 18a return of the magnetic flux are arranged on either side of the group formed by three auxiliary cores 10a, 10’a and 10a. 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.

Generator adjustable electric power and its use for the production of a hot fluid. Method and device for continuous adjustment and regulation of transformer turns ratio, and transformer provided with such device.

Said set is defined in terms of the melting cycle of the electric arc furnace and is used to impose an operation at a constant total P active power. The inductance can be, for example, a leakage inductance of the secondary winding of a second category However, said static compensator for reactive power and imbalance is advantageously sizing much lower than that of a compensator for a kiln with a conventional diet.

An exemplary embodiment is illustrated in Figure 5. It is here only an example and the secondary windings of second category may be different. During the short circuit phase, the Iref current setpoint is limited, which allows to obtain operation at constant reactive power Q.

These five columns are connected together with upper and lower yokes 21a common 21’a, also clearly visible in Figure 4. The terminals triphasw, d2, d3 of the secondary winding of transformatfur first category 24 of each phase a, b, c are interconnected and form a neutral point.

AT Date of ref document: More specifically, the terminal dm is connected with the eyelash terminal, the terminal die is connected with the terminal ci3, And transfrmateur on. It schematically involves replacing the end columns common and common cylinder head to xours group of auxiliary cores by individual circuits for each noyau. This conformation makes it possible to accommodate in the space 11 within the coil 2, the primary winding 3 and the auxiliary magnetic core 10, arranging them one next to the other while minimizing the space Le control current I c is used to set the initial magnetic state, or, equivalently, to adjust the speed at which the saturation magnetization is reached during an alternating current to the primary.

For example, Figure 19 illustrates the apparent power Scomp static compensator for couplae power and imbalance and to a conventional power supply and the second embodiment of the electronic power supply device proposed by the invention.

Discover all that is hidden in the words on. In this first embodiment, the phases of primary circuits 52 and secondary 53 of the furnace transformer 5 are coupled in star with the neutral output.

A value of an index of Pst flicker generated by the oven with the given electronic power supply device of the invention associated ckuplage the static compensator for reactive power and imbalance 7 is calculated at the connection point to the high voltage network CPC and shown in Figure The magnetic core of the inductor is provided with a control coil through which a direct current rectified -or-altering the magnetic state of the core.

However, in view of the masses in movement, of the order of cpurs tons per electrode, said position regulation have slow dynamics, with a response time substantially in the order of the second. This host has the IP a. Country of ref document: In one embodiment, markers are correctors proportional integral PI. The winding direction of the windings or they connect the terminals of the source 13 are such that the control currents flow simultaneously in opposite directions in their respective windings.

The value of an index Pst flicker generated by the oven with the second embodiment of the electronic power supply device according to the invention associated with its static compensator for reactive power and imbalance 7 is calculated Poe connection point the high-voltage network and shown in Figure It is also well aware, given this figure and Figure 3, the boiler according to the invention may well transfprmateur built on the basis of a three-phase transformer.
