Abstract

PURPOSE:To reduce the total dimensions of a set of current transformers, by a method wherein three-phase conductors are so arranged to form an equilateral right triangle and the two transformers on the phases of the larger phase distance are placed at the same position of the direction of the conductor axis and another transformer on another phase is placed at the position shifted from that of the other two. CONSTITUTION:A pipe-type busline is composed of a casing 21 and three-phase conductors 22, 23, 24 inserted in the casing 21 and so arranged to form an equilateral right triangle. These three-phase conductors 22, 23, 24 are supported by a three- phase insulating spacer 25. Two current transformers 31, 32 which are inserted on the two-phase conductors of the larger phase distance are placed around the shields 29a, 29b, 29c of a flange 29 so as to be parallel to each other. And another transformer 30 on another phase conductor is placed at the shield 27a of a flange 27. Thus the transformers 31, 32 are placed at the position shifted from that of the other two. With the above method the phase interval of the conductors is securely maintained and as the shields 27a, 27b, 27c and 29a, 29b, 29c are so arranged to face each other, the interal between the facing surfaces can be reduced, so that the dimensions of the total configuration can be reduced.
