Example Embodiment
[0019] The utility model relates to a replacement fixture for the tension-resistant triple-series insulators of 1000kV ultra-high voltage transmission lines, which is suitable for replacing the first insulator at the cross-arm end of the triple-series and the first insulator at the wire end. The specific work method is as follows:
[0020] Replace the first piece of insulator at the cross arm end such as figure 1 Shown: The cross arm end card 2 is used to connect the hydraulic screw 3 and the front card of the closed card (the front card of the closed card is figure 1 not marked in) implementation. During operation, the other ends of the upper and lower cross arm end clips 2 are respectively installed on the construction holes of the three-connected series plate 1 through the connecting pins 15 and the pin sleeves 14 ( image 3 ). The cross arm end clips 2 are arranged on both sides of the intermediate string insulator 5 . The other end of the cross arm end clamp 2 is conn...
