<p>PURPOSE:To make it possible to assemble a gas insulated measuring instrument use transformer so as to prevent a gap in the abutment parts of the cut surfaces of cut cores by a method wherein two sheets or more of insulating sheets are respectively inserted between the side surfaces at the positions of both ends, which are apart from the abutment parts of the cut surfaces, of the cut cores and frames. CONSTITUTION:Cut cores 2 and 3 formed into a C type of a two-split structure are respectively inserted in the hollow parts of primary and secondary coils 1, both cut surfaces of the core 2 are made contact with both cut surfaces of the core 3 and abutment surfaces A and B are made to form. Here, while frames 11 and 12 with insulating sheets 6 to 8 sticked on their respective inner surfaces are provided in such a way that they are inserted between both side surfaces of the combined cut cores 2 and 3 and between the parts excluding the parts, which are inserted in the coils 1, of the cut cores, bolts are inserted and fixed in bolt holes 13 to 16. At this time, the insulating sheets 6 are respectively stuck one sheet to parts, which correspond to the abutment surface B, of the frames 11 and 12 and the insulating sheets 7 and 8 are respectively two-plied and stuck at the positions of both ends, which are apart from the abutment surfaces A and B, of the frames 11 and 12.</p> |
