Description
Technical Field
The invention belongs to the technical field of cable spacing, and particularly relates to a spacing device for overhead transmission line cables.
Background
The overhead cable is a power supply cable arranged at high altitude; at present, two, four or more split conductors are adopted for each phase conductor of the long-distance and high-capacity ultra-high voltage transmission line. Currently, a 220kV and 330kV power transmission line adopts two split conductors, a 500kV power transmission line adopts three split conductors and four split conductors, and a spacer is arranged between the split conductors to separate the split conductors. The operational characteristics of spacers can be generally divided into two categories, namely damped spacers and non-damped spacers. The damping type spacer is characterized in that: rubber is used as damping material at the movable joint of the spacer to consume the vibration energy of the wire, so as to generate damping effect on the vibration of the wire. Therefore, the spacer is suitable for various areas. However, in view of the economy of the power transmission line, such a spacer is important for a line for a region where the wire is liable to vibrate. The non-damping spacer is poor in shock absorption and can be suitable for lines in areas where vibration is not easy to occur or used as jumper spacers. The prior spacer rod is of a general polygonal bracket structure, and each corner of the bracket is provided with a clip for clamping and fixing the cable, but the cable is fixed in the air more troublesome, so that the overhead operation time is longer. The existing spacer is of a fixed size, the size of the existing spacer is larger than that of the existing spacer when leaving the factory, and when working aloft, the existing spacer cannot be adjusted transversely and longitudinally, so that the installation speed is low, and the working efficiency is low. Therefore, there is a need for a spacer that can be adjusted in both the lateral and longitudinal directions when installing spacers in an overhead operation, so that the operator can easily install the spacer with less effort.
