CURRENT TRANSFORMER CORE AND METHOD FOR PRODUCING A CURRENT TRANSFORMER CORE |
摘要 |
The invention relates to a current transformer core with a ratio of the core outside diameter Da to the core inside diameter Di of < 1.5, a saturation magnetostriction lambdas of = |4| ppm, a circular hysteresis loop with 0.50 = Br/Bs = 0.85 and with an Hcmax = 20 mA/cm. The current transformer core is made of a soft magnetic iron alloy in which at least 50 % of the alloy structure is occupied by fine-crystalline particles with an average particle size of 100 nm or less, and the iron-based alloy comprises, in essence, one combination. The invention also relates to a method for producing this current transformer core. ® KIPO & WIPO 2007 |
