Abstract

The invention relates to an insulator airtightness detection system and method. The detection system comprises an insulator and ultraviolet light sources. A cavity of the insulator is provided with air with fluorescent powder micro particles. The fluorescent powder micro particles are uniformly distributed in the air. The particle diameter of each fluorescent powder particle is 0.2-2.0 mum. The ultraviolet light sources are distributed around the insulator. One end of the insulator is enclosed and the other end thereof is provided with an air inlet. The ultraviolet fluorescent powders have very good floating performance, and can be distributed to each corner uniformly with the air, so that leak detection can be carried out on narrow and small spaces and concealed areas; the smaller the diameter of each ultraviolet fluorescent powder is, the smaller the dimension of each detectable leak point is; and the leak detection method can carry out accurate positioning on the leak points, and visual and obvious effects are achieved. The method can realize the purpose of detecting whether leakage exists through the fluorescence effect, and has the advantages of being simple to operate, small in workload, safe and reliable, good in detection effect and low in cost and the like.

Description

technical field [0001] The invention relates to a container detection system, in particular to an insulator airtightness detection system and method. Background technique [0002] Insulators are special insulation controls that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles, and gradually developed into a high-voltage wire connection tower with many disc-shaped insulators hanging on one end. It is used to increase the creepage distance, usually made of glass or ceramics, and is called an insulator. Insulators should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions, otherwise the insulator will not play a significant role and will impair the service and operating life of the entire line. [0003] For the high-voltage switchgear of GIS combined electrical appliances, the sealing requirements of the equipment are relatively high, an...
