摘要： An amorphous metal core transformer is provided with a plurality of wound magnetic cores composed of amorphous metal strips, and a plurality of coils, each of the coils including a primary coil and a secondary coil, each of the coils further including a bobbin. The primary coil employs different material from that of the secondary coil, e.g., a copper conductor is employed in a primary coil, while an aluminum conductor is employed in a secondary coil. The bobbin has higher strength than that of the amorphous metal strips.

摘要： The invention relates to a mid-frequency high power transformer which is specially used as a welding transformer in resistance welding, comprising a primary winding penetrated by the limb of a transformer core and a secondary winding which are configured as concentrically overlapping cylindrical windings. The windings of the primary windings are formed by a plurality of spirally wound layers of a relatively thin electrically conductive metal strip material, and the windings of the secondary winding are formed by an appropriate number of spirally wound layers of a thicker electrically conductive metal strip material chosen according to the desired reduction ratio between the primary and the secondary windings. The width of the winding layers of the metal strip materials measured perpendicularly in relation to the longitudinal direction is substantially identical to or only slightly smaller than the length of the limb of the transformer core penetrating the windings, and the connection lines on the secondary winding are connected to the front face edges of the windings of the strip material of the secondary coil.

摘要： A bobbin is adapted to support a winding on a permeable core and has a wall that provides a confined thermally conductive channel that causes conduction of heat along a predetermined path from the core to a location outside the winding. A value of magnetizing inductance in a transformer is set by adjusting the gap until the value of magnetizing inductance has been set and attaching a segment of the bobbin to a pair of core pieces to maintain the gap. A permeable slug provides a permeable path outside of the hollow interior space and does not couple the winding, and an electrically insulating coupler is interposed between the slug and the winding to electrically insulate the winding.

摘要： A small footprint power transformer constructed so as to exhibit improved heat dissipation characteristics and an enhanced flow of a cooling medium. The transformer construction achieves small footprint by superimposing the core legs with the windings in vertical relationship. Highly heat conductive plane dissipators are inserted between adjacent finished coil discs and extended beyond the winding structure, terminating in fins arranged to assure maximum heat transfer to a cooling medium flowing therepast resulting in substantial reduction of the temperature rise.

摘要： A compensating device suitable for use in railway car transformers has at least one compensation receptacle in fluid communication connection with the interior of the housing of a transformer and having a fluid volume. A separating element limits the fluid volume in the compensation receptacle. When a change occurs in the fluid volume in the compensation receptacle, the separating element is subject to a change in position. The separating element is designed in the form of a roll-over membrane. The circumferential edge of the membrane is connected to the side walls of the compensation receptacle at a distance form the bottom of the receptacle in a sealing manner. The connection is such that the roll-over membrane, in its rolled-up state, has a position in which it allows for the largest amount of fluid volume by substantially extending in one plane at a distance form the bottom. The membrane can be rolled-out from this position so as to approach the side walls and bottom in the compensation receptacle, reducing the fluid volume.

摘要： A transformer with an associated heat-dissipating plastic element is provided. The transformer includes a hollow main body, a core, a coil and a heat-dissipating plastic element. The core is installed inside the hollow main body while the coil wraps around the core. The heat-dissipating plastic element is also installed inside the hollow main body. The heat-dissipating plastic element encloses the core and the coil. Alternatively, the heat-dissipating plastic element encloses the hollow main body, the core and the coil so that heat generated by the coil may be directly conducted away to the exterior through the heat-dissipating plastic element.

摘要： A method of enhancing the heat dissipating properties of a rigid substrate plate through creation of an array of erect spaced-apart parallelly disposed metallic fins projecting from the heat dissipating surface of the plate. The fins are created by superimposing a sheet of metallic foil upon a metallic plate, with the foil being bonded to the plate by welding utilizing ultrasonic energy. The welds are formed as spaced-apart parallel bands, with the foil being slit adjacent one edge of the band, with the foil thereafter being folded outwardly to form the heat dissipating metallic foil fins. The folding operation is undertaken following the steps of populating the substrate, thereby eliminating the requirement for unusual steps or precautions to protect what otherwise would be outwardly extending metallic fins.
