    摘要： A transformer for current supply and/or signalling purposes, in particular for use in a connector arrangement for electrical circuits in underwater installations, includes a magnet circuit, a first winding having a plurality of turns and a second winding having one or very few turns, whereby turn portions of both windings pass essentially in parallel through one or more openings in the magnetic circuit. For obtaining advantageous electrical properties, turn portions of the first winding are so arranged that along a major part of their length which is surrounded by the magnetic circuit they are individually enclosed by that or those conductors which constitute the turn portions of the second winding that are surrounded by the magnetic circuit.

    摘要： A low leakage inductance inverter transformer utilizing a torodial ferrite core having a primary winding wound thereon, with the secondary winding constructed from stamped conductive clips ranged to encompass portions of the core and primary winding with clip interconnections formed by printed circuit interconnections is described. The conductive clip described includes integral pins for making connection to printed circuit wiring on a printed circuit board. The turns ratio is selected by the pattern of printed circuit interconnection of the conductive clips such that the transformer structure turns ratio is established by the associated printed circuit interconnection pattern.

    摘要： The doughnut-type transformer comprises a spirally wound core consisting of several individual annular cores each tightened by rod members. The annular core is surrounded by transformer sections comprising the primary and the secondary windings. Each winding is composed of turns shaped as sectors in the plane of the transformer cross-section, a cooled turn of the secondary winding being placed between the turns of the primary winding in each transformer section. The turns of the windings surround the annular core so that the geometric center of each winding is displaced from the geometric center of the annular core in the cross-sectional plane thereof and the geometric center of the annular core is farther from the transformer axis. Each turn of the secondary winding is provided with a passage for cooling water to circulate therethrough, which water being supplied and discharged through one and the same contact ring and is first cooling one half of the whole number of the transformer sections and then the other half.

    摘要： The present invention refers to a magnetic core comprising flat magnetic plates superimposed and joined in order to constitute the toroidal form of the core, creating an internal space for the winding and a lateral air gap groove. There being assembled in the open space of the core or air gap, annulling it, an open hoop made of magnetic material having suitable dimensions, whose outer edge penetrates into the interior space of the winding in order thus to create a new internal air gap because the external diameter of the hoop is smaller than the internal diameter of the space available for the inductance coils. In this way a magnetic shunt is situated between the inductance coils in order to regulate their mutual inductance.
