Background
In the electric power system, the overhead distribution line is likely to have a disconnection accident when in operation, and the tension of the wires borne by the two sides of the electric pole is unbalanced, so that a pole falling accident is caused. In order to prevent the expansion of the accident range and reduce the number of the fallen poles, an electric pole which has higher mechanical strength and can bear unbalanced tensile force of a lead is arranged at regular intervals, and the electric pole is commonly called as a tension-resistant pole. When the tension rod of the power line is inclined, the sag of the ground wire connected with the tension rod changes along with the inclination change of the tower, so that the stress of the ground wire is greater than the designed tension, and the safety operation is threatened; therefore, after the tension-resistant rod is inclined, the first measure for ensuring the safe operation of the power transmission line is to release the tension of the ground wire, so that the tension of the ground wire is in a designed safety range.
At present, the tension tower and the ground wire are generally fixedly connected, and the adjustment of the structure mostly needs the line power failure adjustment; however, due to frequent inclination changes of towers in the goaf and the geological bad area, timely adjustment is needed, otherwise accidents such as tower falling and line breaking are likely to happen (especially small span), and the adjustment workload is large and frequent. In order to solve the problem that tension cannot be released in time, avoid serious accidents such as tower collapse and broken lines, reduce operation risks and waste of manpower, material resources and financial resources, the self-adaptive tension releasing device for the tower ground wire is very important.
