Background

When the overhead/cable line connector is in operation, the overhead/cable line connector is influenced by an operation environment, a construction process and the like, and phenomena such as component looseness, connection surface oxidation corrosion and the like are easily generated at the joint, so that the contact resistance is increased and the temperature is increased. The line joint operates under the condition of long-term abnormal temperature rise, the oxidation corrosion of a connecting surface is aggravated, the contact pressure is further released after the temperature reaches a metal soft point, the contact resistance rapidly rises, and finally the electrical connection point is ablated and burnt off, so that the safe and stable operation of the power transmission line is seriously influenced.

Therefore, it is very important to monitor the operating temperature of the line joint. At present, the traditional method is to use an infrared thermal imager to detect the temperature of the line joint regularly at night, cloudy day and load peak period according to an operation and maintenance strategy. In the mode, the infrared thermal imager can only measure at night and in cloudy days, the measurement accuracy is greatly influenced by the environment, and meanwhile, the load peak is not at night, so that a large amount of manpower can not be invested in the actual operation, and temperature measurement equipment can not measure the temperature of all overhead/cable line connectors at the load peak, thereby having high cost and low efficiency.
