Problems solved by technology

[0002] Overhead high-voltage transmission lines are an important part of the power system. High-voltage transmission cables are metal devices. The quality of the quality, insufficient compression during installation and debugging, etc. will cause the resistance of the high-voltage cable core to increase. Trigger arc short circuit, or even burn out the equipment, expand the damage range of the transmission line, and reduce the service life, especially the dynamic and static contacts of the line with high transmission capacity, and the heating phenomenon of the main transformer cable is more serious, the failure rate is high, and accidents occur frequently ; Since the transmission line is a high-voltage live equipment, the hot spot is inconvenient to detect and difficult to find, which seriously affects the safe operation and reliable power supply of the power system

[0003] At present, the detection method of high-voltage lines is mainly that inspection personnel regularly monitor the equipment with thermal imagers or spot thermometers. This method can only measure the situation at that time, and cannot realize real-time detection, let alone alarm, inspection time interval, It is difficult to grasp the measurement angle and measurement position, and it is even more difficult to distinguish the accuracy of the measurement data, which is very prone to missed detection and false detection, which makes the detection of overhead high-voltage lines a big problem and greatly affects the overhead high-voltage transmission lines. normal operation of
