0.2SS CLASS SPECIAL-TYPE HIGH-VOLTAGE MEASURING CURRENT TRANSFORMER

摘要

A 0.2Ss class special-type high-voltage measuring current transformer is a current transformer. A steel core is formed of two "L"-shaped chips of the same size, the ratio of the long side to the short side of the "L"-shaped chip being 3:2, one of the two "L"-shaped chips being a permalloy material chip (1), the other of the "L"-shaped chips being a cold rolled silicon steel material chip (2), and required windings being wound on sides of the steel core. For the steel core in the current transformer, a part of chips adopt permalloy, and a part of chips adopt cold rolled silicon steel, thereby improving steel core performance, so as to utilize structural characteristics of steel cores of different materials to form fractional turn compensation of coils, thereby achieving the objective of precise measurement.
