Abstract

The embodiment of the invention discloses an ageing degree detecting method. The method comprises the following steps: collecting parameters of to-be detected electric wires and cables, wherein the parameters comprise ampacity, leakage current, temperature, humidity, use time and historical load of the to-be detected electric wires and cables; acquiring ageing degree data of the to-be detected electric wires and cables according to the parameters and preset models. The ageing degree detecting method can detect ageing degrees of the electric wires and the cables.

Description

Technical field [0001] The invention relates to the electrical field, in particular to a detection method and a detection device for the degree of aging. Background technique [0002] In recent years, fire accidents caused by the use of old and aging wires and cables have caused significant losses to people's lives and property safety. According to statistics, there were 31,933 fires caused by electrical fires in China in 2000, accounting for 26.1% of the total number of fires in China. Among them, fires caused by aging wires and cables accounted for more than 50% of the total electrical fires. With the increase of household appliances, fires caused by the aging of wires and cables are on the rise year by year. [0003] The existing wires and cables on the market will be tested for aging before they leave the factory. The aging test is to simulate the actual use conditions of the product, and various factors will carry out corresponding condition strengthening experiments on the ...
