Description

Background
The insulator is an important equipment component of a power transmission and transformation system, is widely used in a high-voltage power transmission line, a transformer substation and other electrical network systems, and plays a role in mechanical support and electric insulation of a power transmission conductor; the structure and the appearance of the insulators of different types are greatly different, but the insulators are composed of two parts, namely an insulating part and a connecting hardware fitting.
In the case of porcelain insulators, the mechanical properties of the insulator are reduced and the insulating ability is lost due to many reasons, and such a case is called deterioration of the porcelain insulator. For example, porcelain insulators may deteriorate during production, transportation, installation, and operation. During production, the insulator has the defects of micro-pores, micro-cracks, gaps caused by inconsistent shrinkage coefficients of the connecting piece and the porcelain piece materials, and the like in the manufacturing process. In the transportation and installation process, the head defects of the porcelain pieces can be caused due to collision and the like. After the porcelain insulator is put into operation, because the porcelain insulator has poor tensile property, pores and cracks in the porcelain insulator are expanded in long-time operation to cause deterioration. The insulator on the tower is exposed in humid air for a long time and is easy to be stained with dust, the long-term use performance is reduced, and in order to remove the deteriorated insulator and ensure the safe and reliable operation of a power grid, an accurate and effective deteriorated porcelain insulator detection means must be provided.
