Against the backdrop of social development, the pace of urbanization is gradually accelerating. To meet the needs of transmission and transformation projects, electrical cables are widely used. The main factors for the failure of cable accessories typically include: damage to cable joints and cable terminals. If not addressed promptly, this can cause significant impact. For cable joints, their working stability is only between five to ten years. After that, they will be affected by operating conditions, environmental factors, and human influence, leading to the aging and deterioration of cable joints, thus reducing their working quality. Therefore, seeking new solutions is of great significance for the current work of power companies.
The application of X-ray inspection technology accurately identifies the defects, locations, and sizes of cable joints, enhancing the accuracy of fault detection, checking quality, and efficiency. This provides effective support for the operation and development of cables, fully meeting the core requirements of modern power companies for cable fault detection.
Now, the X-RAY can inspect a wide variety of items, such as electronic components, BGA, electronic device parts, LED components, metal composites, and plastic materials, including issues like open solder joints in BGA casting. It can also accurately and quickly differentiate, as well as conduct detailed inspection and analysis of packaged components and microelectronic systems.
What are the advantages of X-ray inspection technology?
Firstly, it possesses strong penetrability: Due to the relatively short wavelength and high energy of X-rays, only a portion of the material is absorbed during the照射 process, with most of it passing through the gaps between atoms, thereby giving X-rays their strong penetrating power.
Next, the ionizing effect of X-rays: When X-rays are used to irradiate matter, a method can be constructed to measure charge by tracking the deviation of electrons from their original orbit due to the nuclear outer electrons, thereby achieving the purpose of fault detection.
Furthermore, the fluorescence of X-rays: due to their short wavelength, X-rays are difficult to see with the naked eye. However, when exposed to certain compounds, they undergo a fluorescence reaction. For instance, when substances like phosphorus or barium platinocyanide are irradiated, visible light and ultraviolet light are produced, and the intensity of this light is positively correlated with the X-rays. Therefore, in the current stage of cable structure fault detection, relevant personnel can determine the detection method through the advantages of X-rays, thereby improving the timeliness of fault detection and providing support for the stable operation of power enterprises.
In summary, during the current phase of analyzing cable joint failure factors, we can promptly identify issues through X-ray inspection equipment. Moreover, by examining different locations and orientations of the cable, we can quickly diagnose the type of cable defects, enabling the implementation of an inspection plan for the cable's internal structure to rapidly assess cable defect issues.
