Abstract: PURPOSE:To suppress the peak of lightning surge voltage by arranging a magnetic body in the lightning surge intruding path such that the impedance increases in high frequency region higher than several hundred kHz. CONSTITUTION:A series of suspension insulators 3, suspended from the arm 2 of a steel tower 1 in order to suspend a power line 4, is provided with an arc horn 5 and magnetic bodies 6 are arranged around the members 7, 8 of the arm 2.

IPC: C01B31/04
Filed: 1993-08-13
Abstract: PURPOSE: To provide a treating method of a scrap graphite having deposition of contaminant metals to separate the metals from the graphite.  
     CONSTITUTION: A scrap graphite is put in an oxidizing electrolyte soln., on which an electric current is applied. The current is a DC current. The metal may be uranium, and the scrap graphite may be a graphite used to cast a uranium fuel rod. The graphite is decomposed in the electrolyte soln., while the metal is dissolved as accelerated by the effect of the current. The metal falls off from the graphite, and in this case, the metal is dissolved in a long period of time. The treated graphite is then, for example, separated from the electrolyte soln. by filtering, washing, and cleaning. When a graphite is contaminated with uranium and treated by this method, the graphite can be discharged by a normal method without using a special means which is required for harmful radioactive materials.
