[0002] In high-voltage electrical operations such as power line maintenance and power equipment repair, auxiliary insulating gloves are core electrical safety protection equipment to ensure the personal safety of workers. Their insulation and mechanical properties are directly related to the safety of the operation. However, in actual use, insulating gloves are exposed to a complex environment of heat, humidity, and oxygen for a long time, and are also frequently subjected to mechanical flexing caused by hand bending, which leads to the gradual aging of the polymer material of the gloves.

[0003] Material aging can cause a series of problems in insulating gloves, such as decreased tensile strength, deterioration of insulation performance, and surface cracking. If failed insulating gloves are not detected and replaced in time, they can easily lead to electric shock accidents, endangering the lives of workers. In current technology, the assessment of insulating glove aging mostly relies on single performance tests, failing to comprehensively consider the synergistic aging effects of multiple factors such as temperature and flexure, and lacking a unified and accurate life prediction model, making it difficult to accurately predict the remaining service life of the gloves.

[0004] Therefore, proposing a method that can assess the aging degree of insulating gloves from multiple dimensions and accurately predict their remaining lifespan has become an urgent problem to be solved. Summary of the Invention
