Problems solved by technology

[0004] At present, the most commonly used temperature measurement method is infrared temperature measurement, but the workload of infrared temperature measurement inspection is large and the detection accuracy of subtle parts is low; in addition, the cost of real-time monitoring system is high, and the construction is difficult. Machine inspections are becoming more and more common, and the application of image recognition technology is gradually becoming popular. However, carrying an infrared detector will greatly increase the load of the robot and increase the difficulty of automatic detection.

Abstract

The invention relates to a novel coating and system for monitoring abnormal heat generation of a power transmission line and power transmission and transformation equipment, wherein the coating is coated on the surface of a monitored object, the composition of the coating is Zn-5Al-nX, X is a pigment with a reversible temperature indicating function, and n is the component percentage of the pigment. The system comprises a coating, a color sensor, a signal receiver, a processor and an alarm, wherein the surface of a monitored object is coated with the coating, the color sensor is used for monitoring the color change of the coating, the signal receiver is used for receiving the output signal of the color sensor, the processor is used for receiving the output signal of the signal receiver, and the alarm is used for receiving the output signal of the processor. According to the invention, the novel coating is good in chemical stability, small in temperature indicating temperature level, long in service life, low in manufacturing cost and convenient to use; and with the the system, the workload is reduced, the unmanned aerial vehicle inspection time is saved, and the working efficiencyis greatly improved.

Description

technical field [0001] The invention belongs to the technical field of power transmission monitoring, and in particular relates to a novel coating and a system for monitoring abnormal heating of power transmission lines and power transmission and transformation equipment. Background technique [0002] Abnormal heating is a potential threat to the stable operation of transmission lines and important parts of power transmission and transformation equipment. If it is not detected and dealt with in time, once the heating is severe, it is very likely to cause the connection points of the equipment to burn out, causing large-scale power outages, fires and other hazards , seriously affecting the safe and stable operation of the power grid. Therefore, it is necessary to grasp the heating situation in time, so that the inspection personnel can take timely measures to reduce accidents. [0003] The main problems faced: [0004] At present, the most commonly used temperature measurem...
