Specific embodiment
So that Gansu Province is in ± 800kV days center line tangent tower V-type list string composite insulators of fortune as a example, ± 800kV is extra-high
As shown in Figure 2 and Figure 3, the angle between V-type list string composite insulator string 9 exists straightening stream transmission line tangent tower V-type list string structure
Between 85 °～105 °, the upper end of every group of insulator chain 9 passes sequentially through right angle link plate 8 and trunnion hanging panel 7 is connected on cross-arm 1, absolutely
The lower end of edge substring 9 is connected on hanging yoke plate 4 by U-shaped link 11, and wire 5 is suspended on hanging yoke plate 4 by seton device；
Grading ring 10 is provided with insulator chain 9, hanging yoke plate 4 upper center is provided with construction hole 12.Because insulator chain connects about 9
Connect and all adopt circulus, therefore, during along insulator chain 9 axis direction arrangement Work tool, lower fixture can not be arranged on U-shaped link
At 11.
As shown in Fig. 4, Fig. 5, Fig. 6, charged for replacement ± 800kV DC line V-type list insulator string instrument, including on block
13rd, lower card 16, hydraulic screw rod 2 and insulation pull-rod 3, formation telescopic bar after insulation pull-rod 3 and hydraulic screw rod 2 connection, two groups
Telescopic bar is connected to form rectangle framework with the two ends of upper card 13 and lower card 14 respectively, wherein, the stretching of two hydraulic screw rods 2
Contracting end is connected with the lower end of two eradication edge pull-rods 3 respectively, and the two ends of upper card 13 and lower card 16 are respectively arranged with bolt through-hole, two
The upper end of insulation pull-rod 3 is bolted the two ends in upper card 13 respectively, and the fixing end of two hydraulic screw rods 2 passes through spiral shell respectively
Tether the two ends being connected on lower card 16.Flexible for easy for installation, rotation, card contiguous block 14 in the two ends setting of upper card 13, upper card
The upper end of contiguous block 14 with upper card 13 ends bolt through-hole be bolted, the lower end of upper card contiguous block 14 with insulation pull-rod
3 upper end is bolted；Card contiguous block 15 under the two ends setting of lower card 16, the lower end of lower card contiguous block 15 and lower card 16
The bolt through-hole of end is bolted, and bolt is passed through with the fixing end of hydraulic screw rod 2 in the upper end of described lower card contiguous block 15
Connect.
As shown in Fig. 5, Fig. 8 to Figure 13, upper card 13 is by card body 131 and to renovate 132 and match the overturning plate clamp being formed, and described turns over
One end of lid 132 is connected through the hinge with the side of card body 131, forms card-type chamber 134 in the central authorities of overturning plate clamp, in card-type chamber
134 both sides form the clamping hole 133 of insertion；The right angle link plate 8 of the shape in described card-type chamber 134 and insulator chain 9 top and ear
The contour structures at bolt connection between axle link plate 7 are adapted, the cavity size in card-type chamber 134 be slightly larger than right angle link plate 8 with
The appearance profile at connecting bolt between trunnion hanging panel 7；The axis in described clamping hole 133 perpendicular to the axis of insulator chain 9,

The distance between ring 11；
That opens card 13 renovates 132, the right angle link plate 8 above insulator chain 9 for card-type chamber 134 envelope of upper card 13
With trunnion hanging panel 7 junction, the clamping hole 133 on card body 131 is made to be held in right angle link plate 8 and trunnion hanging panel 7 connecting bolt
One side end, rotary flip 132 makes the clamping hole 133 renovated on 132 be held in right angle link plate 8 and trunnion hanging panel 7 connecting bolt
End side, locking renovate 132；
The holding tank 161 of lower card 16 is placed in the upper center of the hanging yoke plate 4 of insulator chain 9 lower section, makes holding tank 161
Notch two side on screw hole and hanging yoke plate 4 upper center construction hole 12 centering, passed through on holding tank 161 with bolt
Screw hole and hanging yoke plate 4 on construction hole 12 make lower card 16 fixation be held on hanging yoke plate 4；
The telescopic end of hydraulic screw rod 2 withdraws, and so that the power on insulator chain 9 is transferred between card 13 and lower card 16, insulation
Substring 9 relaxes, and changes the insulator damaging；
The telescopic end of hydraulic screw rod 2 stretches out, the tension recovery between upper card 13 and lower card 16, and insulator chain 9 just returns to
Normal working condition.
