Infrared detection device of power transmission and transformation equipment

Technical Field

The utility model relates to the technical field of power transmission and transformation equipment detection, in particular to an infrared detection device of power transmission and transformation equipment.

Background

The high-voltage overhead line is a connecting channel for generating, transmitting, transforming and distributing power in a power system, and the safety and reliability of the high-voltage overhead line directly influence the stability of the whole power grid. Electrical testing is a method often used in fault diagnosis for many years, but it is costly and is generally a destructive test.

With the development of technology, the demand for detecting overhead routes is increasing, so that destructive detection can be replaced by infrared detection in some occasions with large area, long distance and rapid scanning. The principle of the infrared diagnosis technology is based on that any object can emit energy which is invisible to human eyes as long as the object has a certain temperature. Physically, the energy is called radiant energy, and the energy is proportional to the thermodynamic temperature of the object to the power of 4. Meanwhile, factors of external environment, such as direct sunlight and the existence of particles in the air, are found in the practical application process of the infrared diagnosis technology, so that the accuracy of infrared diagnosis is possibly affected. Wherein the thermal radiation of sunlight in nature is one of the most serious influencing factors for infrared thermal imaging.

Therefore, in the detection process, the required precision can be achieved through multiple-angle measurement. In the existing infrared imaging detection, the detection is generally fixed at opposite positions, and only one angle can be detected when the detection is carried out, so that the detection precision is relatively low. Meanwhile, for multi-angle detection, a plurality of infrared detection devices with different angles are required to be deployed, so that the cost is increased. Based on the above, we provide an infrared detection device for power transmission and transformation equipment.
