る。 As shown in FIG. 2, the iron core 9 is arranged along the side wall of the container so as to ensure a distance from the circuit breaker 4 within the narrow container 1 for three phases. The iron cores 9 for three phases are supported by one support plate 7. The support plate 7 forms an envelope that roughly follows the outer shape of the three phases of the iron core.
As shown in the figure, a through hole 7a for the primary conductor 15 and a through hole 7b for the stud 11 are provided. 21 is a mounting plate provided inside the container 1 for supporting the device.

定しても良い。 The stud 11 passes through the support plate 7, the presser plate 8, and the core presser plate 10, respectively. nut 12
Accordingly, the distance between the support plate 7 and the presser plate 8 is set to the maximum allowable dimension and is fixed. The iron core 9 is placed on the support plate 7 and is pressed and fixed by a presser plate 10. The core holding plate 10 can be fixed at any position on the fully threaded stud 11 by adjusting the nut 12 that supports and fixes it. Therefore, even if the longitudinal dimension of the iron core 1 changes due to rating fluctuations, etc., the same parts can be used. If deflection of the internal current transformer device 3 is unavoidable, the holding plate 8 or the shield 14 may be fixed to the container 1.

る。 In the above embodiment, since the fully threaded stud is inserted into the core holding plate 10, the core holding plate 10 can be fixed at a predetermined position between the supporting plate 7 and the holding plate 8, and therefore, the core holding plate 10 can be fixed at a predetermined position between the supporting plate 7 and the holding plate 8. Even if the height changes, it can be handled with the same parts, reducing the number of parts. Further, if the stud 11 is inserted through the mounting plate 21, it is convenient because no separate member is required to support the internal current transformer device 3 to the container 1. Furthermore, if the support plate 7, presser plate 8, and core presser plate 10 have the same shape, the number of types of parts will be reduced, which is convenient.
