AI Technical Summary
Existing power line clamp detection technology relies on complex components and equipment, has low accuracy, cannot provide timely warnings, and is cumbersome to operate, thus failing to meet actual needs.
A mixed coating based on pre-prepared chemical reagents is applied to power transmission line clamps and adjacent conductor fittings. The defect level is determined by color comparison. The coating contains a coating matrix, a heat-sensitive fluorescent agent, a thermochromic dye, and a color-changing response filler. A coating colorimetric table is constructed for detection.
It can detect temperature changes in power transmission line clamps without the need for complex components. The color change of the coating provides an intuitive early warning of faults with high accuracy. It also protects the clamps from corrosion and extends their service life.
