[0002] For transmission lines, the external working environment is complex and changeable, and it is easy to cause defects such as corrosion and overheating on the line. Especially in the summer peak load period, the thermal damage caused by the overheating of the diversion plate area of ​​the tension clamp has become a serious threat to the power grid. The hidden danger of safe operation is becoming more and more prominent. The transmission line wire is a current-heating type equipment. When the current-carrying conductor is put into operation, due to the existence of a certain resistance, a part of the power loss will inevitably occur, thereby increasing the temperature of the current-carrying conductor; Among them, the parallel trench clamps used for the connection of the tension jumper and the tension drainage plate connected by bolts are relatively easy to generate heat. When the transmission line transmits a heavy load, the contact resistance of the drainage plate is large and heats up, and a vicious cycle occurs. The contact resistance becomes larger, the heating temperature increases, the oxidation contact resistance is larger, the heating is more serious, until the drainage plate is heated and blown out, which poses a great threat to the safe operation of the power grid; therefore, a simple structure, online real-time It is very necessary to monitor, find overheating problems in time, and ensure the stable operation of the line. The online temperature monitoring device of the deflector based on the high-voltage electric field power supply is very necessary
