Description
Technical field
Device field, specifically a kind of adjustable power transmission and transformation line distance maintaining are maintained the present invention relates to cable space adjustment
Device.
Background technology
In power transmission and transformation line, the distance of circuit still, has depending on the distance between insulator circuit on electric pole, steel tower
When can be because the reason for wind, can make to produce swing between electric wire.Particularly in coastal area or mountain area, once strong wind is swept, just
It can cause and set up electric wire on utility poles and disorderly put, in this case, short-circuit danger between electric wire be there is, in order to anti-
Short circuit phenomenon only between electric wire is, it is necessary to which setting a kind of can keep the device of the spacing between electric wire.The patent No.
201420724939.8 disclose a kind of device of the spacing between holding electric wire, can play a role, but use process
In there is following wretched insufficiency：
When the 1st, sweeping strong wind, the electric wire set up on utility poles will disorderly be put under the action of the forces of the wind, when wind-force is very big, by
Corresponding buffer unit is not provided with device, there can be following hidden danger：
(1), steel wire rope and scale end insulator 4a, scale set end insulator 4b junction are easily torn, Er Qieyou
Very big in wind-force, when electric wire is disorderly put, steel wire rope is constantly drawn with scale end insulator 4a, scale set end insulator 4b junctions
Drag and rub, the service life of device can be greatly reduced, while the steel wire rope of this junction has the danger for the disengaging that breaks again.
(2) steel wire rope also, is connected between scale set top loop 1a and scale set lower loop 1b and the two ends of bow-shaped part 5,
When electric wire is disorderly put, steel wire rope herein is distorted easily in the presence of strong wind, or even several steel wire ropes easily mixed torsion herein
Cheng Yituan, prolonged distortion and pulling, can also greatly reduce the service life of device under wind effect, while this is connected
The steel wire rope at place has the danger for the disengaging that breaks again.
2nd, power transmission and transformation line interval adjusting apparatus is complicated disclosed in the patent No. 201420724939.8, in manufacturing process
Part is more, and many places are connected using steel wire rope, troublesome when each part of device is assembled and connected, and uses very not square
Just.
