Fixing apparatus of current transformer

The current transformer 16 is disposed on an outer circumference of a current transformer attaching-pipe 12 disposed around a central conductor 10 through an insulation-packing 14. A cylindrical container 18 is disposed on an outer circumference of the current transformer 16. A current transformer attaching plate 20 supports the bottom of the current transformer 16. A fixing bolt 34 is fastened to an airtight flange 24 coupled to an upper part of the container 18. By using the fixing bolt 34, an upper part of the current transformer 16 is pressed through a current transformer pressing plate 36 and an insulation-packing 38. The movement of the current transformer 16 in the axial direction is regulated, a rotational shift is prevented, and the space in the axial and radial directions of the container 18 is reduced.
