Embodiment 1
[0030] Such as Figure 1 to Figure 3 As shown, the UHV transmission line tension insulator string entry and exit operation connection device includes a flexible body 1, a first connector 2, a second connector 3, and a tightener 4. The flexible body 1 includes two first insulators with the same length Shaped portion 5 and a second strip-shaped portion 6, the ends of the two first strip-shaped portions 5 and the ends of the second strip-shaped portion 6 are connected at the same point to form a Y shape; the first connector 2 includes a connecting seat 7, a U U-shaped connector 8, the two sides of the opening of the U-shaped connector 8 are connected by the first bolt 9 to form a closed loop, and the U-shaped connector 8 is installed on the connecting seat 7 vertically and rotatably around the vertical line; one end of the second connector 3 For the connection part 10 connected with the second bar-shaped part 6, the other end is a U-shaped part 11, the bottom of the U-shaped part...
Embodiment 2
[0032] Such as Figure 4 As shown, different from Embodiment 1, it also includes an extended flexible piece 14, and the two ends of the extended flexible piece 14 are respectively provided with a first child buckle 15 and a first female buckle 16; Disconnection part 17, the two ends of disconnection part 17 are respectively provided with the second female buckle 18 that cooperates with first child buckle 15, the second child buckle 19 that cooperates with first female buckle 16; The second female buckles 18 are snapped together to connect the disconnected parts 17 . The second strip portion 6 is provided with two tighteners 4 respectively disposed on both sides of the breaking portion 17 .
[0033] Working method and principle: such as Figure 5 shown
[0034] 1) The ground operator adjusts the length of the connecting device by increasing or decreasing the length of the second strip portion 6 on the ground according to the total length of the insulator string 20 and the co...
