Introduction of composite insulators for electrical appliances
Composite insulators can be divided into: line composite insulators and composite insulators for power stations and electrical appliances. It can also be divided into rod-shaped suspended composite insulators, pin composite insulators, cross-arm composite insulators, pillar composite insulators, wind-proof bias composite insulators, etc. The detection principle is based on the water spray classification method of the Swedish Power Transmission Research Institute (STRI) to stop the composite insulators. Judgment of water-based state.
Based on advanced digital image processing technology, after extracting the gray level information such as the information entropy, seed rate, and spectrum amplitude mean value of the water-repellent picture, the shape factor and area percentage of water droplets or water traces are objective to the water-repellent state of the composite insulator. To judge, the function is charged to detect the hydrophobicity of various composite insulators.
Detects the water repellency of silicone rubber and RTV spray data, automatically and accurately analyzes the water repellency grade, records various data and graphics of each test, and can query the test records of each and each string of insulators, automatically discriminates the development trend of water repellency, analyzes and discriminates Pollution flashover resistance, wet flashover performance, provide a scientific basis for maintenance and selection.
