Development and application of a measuring tool for creepage distance of composite insulators

Composite insulators in high voltage transmission lines mainly play the role of support, fixation and insulation. The creepage distance is a necessary test item for composite insulator detection. Due to the difficulty in measuring the creepage distance of composite insulators, a composite insulator creepage distance measuring tool is developed based on the traditional measuring method, which uses the combination of laser and hand-held measuring end to measure the creepage distance of composite insulators. In the actual application, through the comparison of the old and the new method, the results show that this set of measuring tools not only solves the problems of heavy workload and low measurement accuracy when testing the creepage distance of composite insulators, but also improves the flexibility and reliability of measurement work through the measurement path displayed by laser and the replacement of rollers with different specifications, as well as shortens the measurement time of creepage distance of composite insulators and improves the work efficiency.
