20150348704 | 0.2Ss class special-type high-voltage measuring current transformer - 0.2Ss class special-type high-voltage measuring current transformer belongs to a field of current transformer. An iron core includes two kinds of “L”-shaped sheets with the same size, wherein a ratio of a long side to a short side of each “L”-shaped sheet is 3:2; a first kind of the “L”-shaped sheets are permalloy sheets (1) and a second kind of the “L”-shaped sheets are cold rolled silicon steel sheets (2); and required windings are wound on each side of the iron core. Sheets of the iron core of the current transformer include the permalloy sheets and the cold rolled silicon steel sheets, which improves performance of the iron core. Utilizing structural characteristics of the iron core of different materials, a fractional turn compensation of coils is formed, which realizes a precise measurement. | 12-03-2015 |
