20080290982 | TRANSFORMER CORE - A transformer core includes a stack of a plurality of planar core plates of a magnetically permeable material, which plates each consist of a first and a second sub-part that together enclose at least one opening. The sub-parts can be fitted together via contact faces that are located on either side of the opening and that extend obliquely with respect to the centerline of the core plate. The invention also relates to the use of the described transformer core in a Coriolis flowmeter with the Coriolis tube extending through the opening so as to induce a current in the tube. | 11-27-2008 |
20090237196 | Method for manufacturing transformer, and transformer - A core is configured with two O-type cores and an I-type core which is separate from the O-type cores. In a transformer comprising a core of the type, by incorporating a first O-type core, a bobbinless coil block and a second O-type core to be stacked on a terminal block sequentially, excellent assemblability is achieved. Further, the first O-type core is incorporated from one side to the terminal block, and the bobbinless coil block and the second O-type core are incorporated by stacking up from the other side. Further, the first O-type core, the bobbinless coil block, the second O-type core and the terminal block are assembled by being stacked up. | 09-24-2009 |
20110210812 | HOLDING DEVICE FOR A CAST RESIN TRANSFORMER WINDING - A holding device for fastening a cast resin transformer winding relative to a transformer core has a support element and a receiving element attached to a tie rod. By fastening the support element to the receiving element attached to the tie rod, a cast resin transformer winding can be fixed rigidly and precisely centered relative to a transformer core. By attaching the receiving element directly on the tie rod, circulation in the lower region of the cast resin transformer winding or of an insulating cylinder also attached to the support element is ensured and thereby the thermal properties of a cast resin transformer winding produced in this way are improved. Furthermore a modular and thus simple design of the cast resin transformer is possible due to the possibility of connecting the receiving element to the tie rod by way of the support element. | 09-01-2011 |
20110316659 | TRANSFORMER TESTING - A method of testing a transformer prior to installation in a high-pressure environment wherein the transformer comprises a transformer core comprising a stack of a plurality laminations, is provided. The method comprises applying a mechanical compression force to the stack, the force being at least equivalent to the ambient pressure of the high-pressure environment; and testing the electrical efficiency of the transformer. | 12-29-2011 |
20120161915 | AMORPHOUS TRANSFORMER - An amorphous transformer which includes an amorphous core formed of an amorphous material with a lap provided at an upper portion and allowed to stand in substantially a vertical direction while being supported at a core support member, and a coil which is fitted with the amorphous core. The core support member is formed by integrating a core support member for supporting a side surface of the amorphous core and a corner support member for supporting a corner portion of the core. The core support member is provided in substantially a vertical direction along at least one of the side surfaces of the core. | 06-28-2012 |
20120206232 | REACTOR - To provide a reactor whose number of components is small and that exhibits excellent assemblability. A reactor | 08-16-2012 |
20130093559 | Stereo-Triangular Wound-Core Power Transformer With a Voltage Class More Than or Equal to 110kV - A stereo-triangular wound-core power transformer with a voltage class more than or equal to 110 kV is disclosed, which includes a stereo-triangle wound-core and windings, wherein the core includes iron yokes and core pillars which are arranged in a stereo-triangle shape, with every two adjacent core pillars connected through an iron yoke. The power transformer further includes angle rings, end rings, insulating end rings, insulating end plates and a frame-type clamp, wherein the angle rings, insulating end rings, end rings and insulating end rings are arranged at both ends of the core pillars in sequence, respectively, and the ends of the core pillars are arranged on the insulating end plates. The frame-type clamp covers the iron yokes, and the supporting boards of the frame-type clamp are connected with the insulating end plates through pressing screws. | 04-18-2013 |
20130249666 | REACTOR AND MANUFACTURING METHOD THEREOF - First and second divisional cores each including right and left leg portions and a yoke interconnecting those together are formed by molding respective yoke-side core members in a resin. Cylindrical core mounting portions extending from the outer circumference of the surface of the yoke-side core member are formed integrally with the respective right and left leg portions of the first. divisional core. I-shaped leg-portion-side core members and spacers are attached in the cylindrical core mounting portion formed in each of the right and left leg portions. The surface of the yoke-side core member molded in the resin and the surface of the leg-portion-side core member are disposed so as to have a spacer therebetween. The two divisional cores are joined together by butting respective leg portions of the two divisional cores with each other to form an annular mold core, and a coil is wound around the mold core. | 09-26-2013 |
