Background

The ground wire composite insulator is an insulator for insulation and lightning protection of a communication line on a power transmission line, and is installed on a lightning conductor of the power transmission line, wherein the lightning conductor is also called a ground wire and is used for power communication at ordinary times. When the insulator is in normal operation, the lightning conductor and the iron tower are insulated by the insulator, so that smooth electric power communication is ensured. When lightning strike occurs, the lightning falls on the lightning conductor, the lightning overvoltage breaks down an air gap between two arc striking electrodes on the ground wire insulator, and strong lightning current is led into the ground through the iron tower, so that the normal operation of the power transmission line is protected.

At present, two electrodes of the traditional ground wire composite insulator are simply fixed on two ends of a ground wire composite insulator hardware fitting. When the transmission line runs, the wire is in a low-frequency vibration state under the action of wind for a long time, and the vibration can be transmitted to the ground wire insulator, so that the electrodes at two ends of the ground wire composite insulator hardware are loosened, the electrodes move on two ends of the ground wire composite insulator hardware in the radial direction and the axial direction, and the air gap between the two electrodes is changed to a large or small extent. Therefore, when the air gap of the electrode is reduced, the insulation is insufficient under the condition of ice coating and rain, and normal electric power communication is influenced; when the air gap of the electrode is enlarged, the air gap can not be effectively punctured in case of lightning stroke, and the safety of protecting the power transmission line can not be achieved.

Therefore, it is necessary and practical to ensure that the above-mentioned faults do not occur in the two electrodes of the ground wire composite insulator.
