Description
Technical field:
the invention relates to the technical field of electric auxiliary equipment, in particular to a damper position adjusting device for an electric transmission line.
The background technology is as follows:
a certain number of damper is installed on the transmission line wire to eliminate the vibration energy of the wire and prevent the wire from being broken due to fatigue caused by vibration. In the use, due to vibration, environmental and air temperature change, human factors and other reasons, the phenomenon of loosening and displacement of the damper can occur, so that the damper cannot play a protective role, in the operation of recovering the correct position, the damper must be realized by manual operation, the process is complex, a certain personal safety problem exists, and particularly, the live reset work of the damper displacement of a 110kV double-circuit line is almost impossible due to the problem of the safety distance of a combined gap, and the damper is only reset manually under the condition of power failure.
The damage to the wire after the damper is shifted has two points: 1. the vibration prevention and energy dissipation effects on the lead cannot be achieved. 2. Wearing out the wire causes serious accidents. If the damper slides and shifts to the middle of the gear, when the aluminum wrapping tape wrapped on the wire blocks the damper to slide to the lowest point of the sag or slide to the lowest point, the damper shakes along with wind on the wire, the clip rubs with the wire, the wire is seriously worn, the mechanical and electrical properties are reduced, and accidents are caused.
The traditional method for eliminating the displacement of the wire damper is usually carried out by adopting a manual resetting method. Through field investigation, we find that the manual reset elimination method has a plurality of disadvantages, such as: 1. the manual operation is realized, so that the process is complex, and the personal safety is also a certain problem. 2. If the power failure is eliminated, the power failure is planned to be carried out, and the power failure cannot be effectively eliminated in time. 3. The wire damper displacement is eliminated by the equipotential rope ladder method as the electrification elimination. Panelists found the above method by field trials: the equipotential rope ladder method can remove the vibration damper shift, but the equipotential operation has more limited conditions, has a plurality of defects 1, can only remove the vibration damper defect of the lower phase wire, and the vibration damper defect of the upper phase wire cannot be performed due to the limitation of the combination gap; 2. equipotential operation is easily affected by weather factors, so live working is greatly affected by weather conditions.
