Le dispositif de déclenchement comporte au moins un transformateur de courant pour l'alimentation de circuits électroniques. Le transformateur de courant comporte un circuit magnétique (10), entourant un conducteur (13) primaire, un enroulement secondaire (11) bobiné sur une partie du circuit magnétique formant un noyau (14), et un shunt magnétique (15) mis en dérivation sur le noyau magnétique (14). Le shunt magnétique comporte un entrefer (16). Lorsque le courant circulant dans le conducteur primaire (13) est de faible valeur, le flux magnétique passe essentiellement par le noyau de l'enroulement secondaire. A fort niveau de courant une grande partie du flux magnétique traverse le shunt à travers l'entrefer. Le dispositif de déclenchement est, par exemple, installé dans un disjoncteur. |

| 125 | Electrical reactors | EP79302940.6 | 1979-12-18 | EP0012629A1 | 1980-06-25 | Fujioka, Yoshiki |
An electrical reactor has a core (11), for example composed of silicon steel plates, forming a closed magnetic circuit including a gap (14). A by-pass member (20) across the gap (14) forms a magnetic by-pass path around the gap (14). The by-pass member (14) may be a silicon steel plate with its plane parallel to the plane of the plates forming the core. A coil (15,17,18) is wound on the core (11). The inductance of the reactor depends upon magnetic saturation of the by-pass member (20). When current in the coil is small reactor inductance is large because the by-pass member (20) does not saturate, but when current in the coil is large the by-pass member (20) saturates and reactor inductance is reduced. The reactor can be employed for blocking leakage of noise generated at the time of commutation in a thyristor controlled converter. |

| 129 | Method and apparatus for isolating and switching lower voltage pulses from high voltage pulses in electrocrushing and electrohydraulic drills | US14494461 | 2014-09-23 | US10113364B2 | 2018-10-30 | William M. Moeny; Josh Gilbrech; Richard Adler |
| Method and apparatus for isolating and switching lower voltage pulses from high voltage pulses in electrocrushing and electrohydraulic drills. A transformer with a high permeability core acts as a magnetic switch or saturating inductor to switch high voltage pulses to initiate an electrocrushing arc and lower voltage pulses to sustain the arc. The transformer isolates the lower voltage components from the high voltage pulses, and switches to deliver the low voltage current when the core saturates. The transformer enables impedance matching to the arc during all stages of drilling. The saturation time of the transformer core is the time delay between initiation of delivering the high voltage pulse and initiation of delivering the lower voltage current. | ||||||

This allows the native leakage inductance to be altered to satisfy demands for various different resonant frequencies. | ||||||

| Provided is an inductor winding method and an inductor winding device. The inductor winding method comprises steps of: A. dividing turns of coil of each winding of the inductor into a first winding and a second winding based on a preset ratio; B. winding the first winding on one of multiple magnetic columns, and winding the second winding on another one of the multiple magnetic columns which is different from the magnetic column on which the first winding is wound; and C. performing step A and step B cyclically until all the windings of the inductor are wound. With a coupling inductor having interleaving-wound structure, power frequency magnetic fluxes generated by magnetic lines in magnetic columns counteract one another, thereby solving the problem of high magnetic flux density in a magnetic core while achieving certain leakage inductance. | ||||||

| A common mode inductor includes a bobbin with two windings. A first winding is positioned between a first end flange and a first offset flange. A second winding is positioned between a second end flange and a second offset flange. The windings are spaced apart by a center section without windings. A pair of E-cores, each having a pair of outer legs and a center leg, are positioned in a passageway of the bobbin such that the center leg of each E-core is surrounded by a respective one of the two windings. An I-bar is positioned in the center section of the bobbin between the two offset flanges with the I-bar perpendicular to the outer legs and the center legs of the two E-cores. The I-bar core increases leakage inductance between the two windings to improve the suppression of electromagnetic interference caused by common mode noise in the two windings. | ||||||
