[0037] By attaching the outdoor current transformer body 5 to the inside of the top frame 2, and then moving the two slides 10 on the two fixed rods 9 respectively, the telescopic locking rods 12, which are equipped with the first connecting springs 13 on the two slides 10, can be moved to the outdoor current transformer body 5. Then, the elastic force of the first connecting springs 13 can make the telescopic locking rods 12 automatically extend and engage with the embedded holes 66 on the outdoor current transformer body 5 for locking and positioning the outdoor current transformer body 5. Next, the connecting handwheel 22 is rotated so that the connecting handwheel 22 can drive the double-ended lead screw 17 to rotate. In this way, the two displacement plates 18 on the double-ended lead screw 17 can move towards each other, so that the locking blocks 19 at the two displacement plates 18 can engage with the positioning grooves 7 on the bottom plate 6 for securely locking and fixing the outdoor current transformer. This facilitates quick disassembly and maintenance of the entire outdoor current transformer without the need to use bolts to fix the outdoor current transformer, improving maintenance efficiency and ensuring the convenience of using the outdoor current transformer.

[0038] By attaching two brackets 23 to the top of the top frame 2 and then fixing the two brackets 23 by rotating two positioning bolts 30, the protective plate 24 can be installed on the top of the outdoor current transformer body 5. Then, the movable rod 26 with the second connecting spring 27 can be attached to the fixing block 29 to support and fix the two movable baffles 28. In this way, the protective plate 24 and the two movable baffles 28 can provide shade and rain protection, reduce the impact of weather on the outdoor current transformer, and allow the outdoor current transformer to be used safely and reliably. At the same time, by rotating the four movable rotating plates 11, the four movable rotating plates 11 can be positioned in the grooves 15 of the outdoor current transformer body 5 to prevent the outdoor current transformer from becoming loose and improve the stability of the outdoor current transformer.
