Title: Transformer
Inventor: INOUE TAMOTSU
IPC: H01F27/00
Filed: 1988-06-14
Abstract: PURPOSE:To improve the measurement sensitivity of partial discharge, and to inhibit the increae of the potential of a node by connecting a capapcitor cylinder, into which a zinc oxide arrester element is inserted, between the connecting section of a high-tension external winding and a high-tension internal winding and the ground. CONSTITUTION:A capacitor cylinder 11 into which a zinc oxide arrester element 12 is inserted is connected between the connecting section of a high-tension external winding 7 and a high-tension internal winding 5 and the ground. A partial discharge mearusing instrument 17 is connected on the grounding side of a capacitor cylinder 11. Consequently, since the elevation of the potential of the connecting section is inhibited by the discharge voltage of the zinc oxide arrester 12, potential is not increased more than that, over-voltage does not appear in the connecting section, and reliability is improved. Since partial discharge is measured in approximately the intermediate section of the winding, both partial discharge generated on the high tension side and partial discharge generated on the low tension side are measured in approximately the same magnitude, thus measuring even partial discharge generated in any section with sensititvity better than conventional divices.

Abstract: PURPOSE:To obtain the title cast iron having high mechanical strength and toughness at a low cost by removing the dephosphorizing slag generated in the dephosphorizing stage, diluting the remaining slag to form dil. slag, removing the dil. slag and then supplying the molten iron freed of the dil. slag in a casting mold, and casting the molten iron into a specified shape. CONSTITUTION:Blast-furnace molten iron is pretreated to reduce the content of impurities, especially phosphorus, the composition of the pretreated molten iron is adjusted, and the molten iron is cast into a specified shape. In this case, the dephosphorizing slag generated in the dephosphorizing stage is removed, the remaining slag is diluted, and the dil. slag is removed. By this method, reinfiltration of phosphorus into the molten iron can be almost completely prevented, and the content of phosphorus can be remarkably reduced. In addition, since the content of impurities, especially phosphorus, can be thus reduced, the toughness can be enhanced. Moreover, since the cost of the blast-furnace molten iron itself is low, the production cost can be remarkably reduced.
