The core comprises three single frames made of amorphous alloy strips by winding and are identical in structure, and the single frames have a rectangular shape; the vertical sides of every two adjacent frames fit together fixedly to form a core pillar, and the horizontal sides of the single frame form iron yokes; the cross sections of the core pillars have an approximately circular or polygonal shape; the transformer further comprises a clamp, comprising a quasi-triangular upper and lower clamp, and posts, the lower clamp is provide with three food pads; the iron yokes in the lower portion of the iron core are located on the foot pads, and the high-low voltage winding is wound on the core pillars; | 06-27-2013 |
20130200967 | NON-ENCAPSULATED-WINDING STEREO WOUND-CORE DRY-TYPE AMORPHOUS ALLOY TRANSFORMER - A non-encapsulated-winding stereo wound-core dry-type amorphous alloy transformer. The core of the transformer has a stereo structure. Three lower yokes are placed on a base of a lower clamp, and an upper clamp and the lower clamp are connected with each other by several press screws. Low-voltage windings include a foil-wound or wire-wound cylindrical structure, while its high-voltage windings are wound with oxygen-free copper wires wrapped in an insulate paper and processed through vacuum pressure impregnation. Upper and lower padding blocks support and compress the high-voltage and low-voltage windings, so that the product is formed in a rigid stereo frame structure. | 08-08-2013 |
20140375414 | OPEN TYPE STEREOSCOPIC TRIANGLE AMORPHOUS ALLOY WOUND IRON CORE - An open type stereoscopic triangle amorphous alloy reel iron core comprises an iron core body wherein a three-phase round core column combined by three identical closed iron core single frames, and the combined round core column is arranged in a stereoscopic equilateral triangle shape. Each iron core single frame comprises iron yokes arranged on an upper end and a lower end of the iron core single frame, the iron yoke on one side of each iron core single frame is provided with an opening, and the iron core single frame can be assembled or disassembled at the opening. By providing the opening, on the iron yoke on one side of each stereoscopic triangle amorphous alloy iron core single frame, coils can be independently wound in the production process of a transformer, and the finished coils are directly sleeved on the three core columns, improving production efficiency and saving production cost. | 12-25-2014 |
20160024719 | PAINT IMMERSING PROCESS FOR INSULATING PAPER - The invention provides a paint immersing process for insulating paper, comprising the following steps: step | 01-28-2016 |
20160027573 | Coil Structure of Open Ventilated Type Stereoscopic Wound-Core Dry-Type Transformer - A coil structure of open ventilated type stereoscopic wound-core dry-type transformer, comprising wire disks formed by wound wires and fixing parts. The fixing parts are provided with clamping grooves for fixing the wire disks. The wire disks are fixed and wound around the fixing parts to form the coil structure. The outer layers of the wires are coated with insulating paper with insulating paint. And by insulating paint, wires are adhered mutually and wire disks adhere to fixing parts, which combine into an integral structure. The coil structure does not require another paint impregnation process, so the process is simplified. And by the insulating paint on the insulating paper, wires are adhered mutually and wire disks adhere to fixing parts, so the structure is stable and firm and ensures the electrical equipment meets the requirements of electric performance, mechanical property and insulating property. | 01-28-2016 |
20160055959 | Fixing Structure for Upper Pressing Blocks of Stereoscopic Wound Core Open-Ventilated Dry-Type Transformer - A fixing structure for the upper pressing blocks of a stereoscopic wound core open-ventilated dry-type transformer, including three coils arranged vertically. Three coils are arranged in triangle; an insulation ring is arranged at the upper end of each of the coils; a pressing block used for pressing the corresponding coil is placed on the upper surface of each insulation ring; an upper clamp is arranged above the pressing blocks; and press rods for pressing the pressing blocks are arranged on the bottom surface of the upper clamp. According to the disclosure, the upper clamp presses the pressing blocks and then the pressing blocks 3 press the coils, so the loosening of the coils is prevented and impact resistance of the coils is ensured; moreover, the pressing blocks which press the coils do not need to be tensioned by a lower clamp through utilizing a screw, and thus, the phase-to-phase distance between three coils will not be increased and the insulation distance between the coils is not to be increased; and in addition, four pressing blocks are evenly arranged on each coil, and thus, the coils bear more uniform stress, so the coils can be pressed better. | 02-25-2016 |
20160055970 | High Voltage Wire Leading Method for Stereoscopic Wound Core Open Ventilated Dry-Type Transformer - The invention discloses a high voltage wire leading method for a stereoscopic wound core open ventilated dry-type transformer, which comprises the steps of fixing stereoscopic wound cores arranged in a triangular shape between an upper clamp and a lower clamp, winding A, B and C three phase coils on the stereoscopic wound cores and arranging a high voltage wire leading bracket on the upper clamp, wherein the high voltage wire leading bracket is provided with connecting terminals which respectively correspond to the A, B and C three phase coils; and each phase coil is respectively provided with a wire inlet terminal and a wire outlet terminal. In the high voltage wire leading method, each of the three A, B, and C phase coils is provided with two wire outlet terminals and the numbers of turns of the three phase coils are still equal, so that under the condition of not changing the numbers of the turns of the coils, the added wire outlet terminals make leading more conveniently and the lead structure simpler. | 02-25-2016 |
20160086706 | AMORPHOUS ALLOY TRANSFORMER IRON CORE OF THREE-DIMENSIONAL TRIANGLE STRUCTURE - An amorphous alloy transformer iron core of a three-dimensional triangle structure belongs to the technical field of electrical devices.
