摘要： PURPOSE:To reduce the thickness of insulating film of a superconducting coil conductor and to enhance the space factor of a superconducting wire by a method wherein a pair of flat ring-shaped metal plates, having a spiral-shaped coil-housing groove and a prescribed potential respectively and insulated with each other, are laminated. CONSTITUTION:Flat ring-shaped metal plates 1A to 1G, provided with the groove wherein a superconducting coil conductor 10 of a spiral double-pancake-wound coil 5 will be housed, are laminated through the intermediary of an insulating layer 23. One of a pair of plates 1A to 1G is maintained at the same potential as an external lead-out part through an outer circumferential side junction part 17, other part is maintained at the same potential as the inner circumferential side transition part 6, which is connected to a power supply part 22, through the transition part 6, and a metal plate laminated body 1 is fixed by a clamping bolt 30. Using the constitution wherein the potential of a pair of metal plates, with which each layer coil is pinched, is maintained at the prescribed value and potential difference is reduced to the value equal to the allotment voltage of each layer coil, the potential difference which is formed by the dielectric covering of the superconducting coil conductor can be reduced, the space factor of the superconducting wire can be enhanced by the reduction in thickness of the covering, and the magnetic flux density of a toroidal magnetic field can also be enhanced without increasing the size of the coil.

摘要： PURPOSE:To obtain a superconducting coil device having a coil deformation- preventing means capable of absorbing the variation of the gap length, fixing a superconducting coil, firmly in a coil casing. CONSTITUTION:A superconducting coil 1 having a counter-ground insulation jacket 5 is housed in a rigid coil casing 7 made of a nonmagnetic metal. It has a coil deformation preventing means 11 composed of filler vessels consisting of thin stainless alloy sheet-made bag-like parts 13 previously inserted in the gap 9 between the jacket 5 and casing 7 and injecting pipes 14 piercing the coil casing to communicate with the parts 13, and filler injected with pressure into the vessels and heated to harden whereby this means prevents the coil from being deformed by an electromechanical force.

摘要： PROBLEM TO BE SOLVED: To provide a molded transformer having an integrated molded winding supporting structure wherein no gap is produced between it and a lower spacing piece formed on a lower frame supporting the molded winding, and an assembling method for the molded transformer. SOLUTION: Unvulcanized rubber 7, composed of silicone rubber adhesive, is applied to the surface of a lower spacing piece 6b, bonded to a lower frame 5b that is to be installed with a molded winding 1 inserted thereinto, opposed to the molded winding 1 to a height above the dimensional error of the axial length of the molded winding 1. The molded winding 1 is fit so that the unvulcanized rubber 7 layer will be pressed. The molded winding 1 is then positioned between the upper and lower frames to vulcanize the unvulcanized rubber 7 to obtain a supporting structure integrated with the lower spacing piece 6b composed of a rubber elastic body layer.

摘要： PROBLEM TO BE SOLVED: To improve airtightness by covering the inner and outer circumferences and the upper and lower ends of a winding and also a lead wire projected toward the exterior of the winding with moisture-proof sheets and sealing a joint part at which the moisture-proof sheets are joined together by fusing. SOLUTION: The inner and outer circumferences of a high-voltage winding 2a and the upper and lower ends of a winding 2 and also a lead wire 5 projected to the exterior of the winding 2 are respectively covered with moisture-proof sheets 41a, 41c, 41d comprising a fusible polyethylene film. The respective joint parts 6a, 6c, 6b, 6d of moisture-proof sheets 41a, 41b, and moisture-proof sheets 41c, 41d are held between heated press-fitting parts and press-fitted by heat whereby a polyester film forming the respective parts 6 is melted and thermally welded to airtightly join the respective moisture-proof sheets 41 together and fix them. Therefore, the quality of the winding 2 can be maintained and airtightness can be held without damaging moisture-proofness.

摘要： PURPOSE: To obtain a process for producing sand molded goods which improves the uniformity of the resin characteristics and the characteristics of the sand molded goods and is stably adjustable the resin characteristics by oscillating resins and sand via an oscillator after vacuum impregnation of the sand with the resin. CONSTITUTION: An iron core 3 and coil 4 which are previously assembled are installed in a transformer case 1 and silica sand No.4-5 is charged therein. The amt. of the silica sand to be charged is confined down to the lower part of a high-pressure bushing 6. The case 1 contg. the silica sand is subjected to preheating and drying stages in a vacuum impregnation furnace and thereafter, an epoxy resin is poured therein. The epoxy resin is adequately subjected to flow rate control from the lower part of the tank 1 through a pipe and is risen to the upper part of the tank. Consequently, a resin layer made voidless is formed. Ultrasonic waves of, for example, 1.4kw are thereafter impressed on the resin layer via liquid 8 from the bottom and the side faces by using the oscillator 7. As a result, the molded resin layer subjected to closed packing is formed. The full-mold type transformer which is thermally and electrically stable is obtd. in such a manner.

摘要： PURPOSE:To reduce the loading of mold resin and hereby ensure an outdoor aid transformer with light weight and with the low cost. CONSTITUTION:A wiring 2 wound on a winding core 20 is mounted on a casing side surface 10 being part of a metal casing 1, and an upper mold as a metal mold for covering the upper portion of the former members and a lower mold for covering the lower portion of the same are mounted to form a space for accomodating the wiring. Molding resin is injected into the space whereby the casing side surface 10 and the wiring 2 including a winding core 20 are integrally formed with the molding resin 4. After the upper and lower molds exclusively used for a metal mold are removed, an iron core 3 is inserted into the molded and integrally formed wiring 2 and casing side surface 10, and a casing lower part 12 and a casing upper part 11 being part of the casing 1 are mounted together with the casing side surface 3. Thereupon, a filler 5 is filled in a gap between an iron core 3 surface and other members at a proper timing to improve a cooling effect of the iron core 3. Further, conductive sheets 61, 62 are also molded upon the molding to prevent partial electric discharge from being produced across a gap between them and the casing.
