<p><P>PROBLEM TO BE SOLVED: To provide a current transformer for measuring instruments, capable of easily changing the form of a coupled body according to the form of a wiring, accurately measuring currents, and protecting wirings of turning core units even at the junctions of the core units. <P>SOLUTION: The current transformer 5 for measuring instruments, capable of detecting a current flowing through the wiring, is provided with the coupled body 3 constituted by joining a plurality of the core units 1 to each other, having cases 7 and iron cores 9 and coils 11 provided for the inside of the cases 7. The core unit 1 is engaged with other core units, in such a way as to be easily detached and freely rotatable, constituted in such a way as to surround the wiring by the coupled body and detect a current flowing through the wiring, when the core units are each joined to form the coupled body, and is provided with cover parts 27 for preventing the coils etc. from exposing, when one core unit among the core unit joined to each other is turned with respect to the other core unit. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
