<p><P>PROBLEM TO BE SOLVED: To provide a small current transformer that can be used with large current. <P>SOLUTION: The current transformer 1 is provided with an outer cylinder 17, an inner cylinder 16 arranged inside the outer cylinder, and cooling water hoses 15a, 15b and 15c fitted to one end of the outer cylinder 17 and the inner cylinder 16. When current is made to flow in the current transformer 1, cooling water is introduced into the current transformer 1 from one of the cooling water hoses 15a, 15b and 15c, and cooling water is discharged from one of the hoses. Primary winding 11 wound to a ferrite core 14 is coated and linkage is previously prevented. The outer cylinder 17 and the inner cylinder 16 are joined, and they function as secondary winding 12 having an output terminal for making current flow to a heating coil. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
