The invention discloses a judgment method of equivalent running time of a silicone rubber material based on thermogravimetric analysis (TGA). The judgment method comprises the following steps of S1, heating a silicone rubber sample and measuring a thermogravimetric curve of the silicone rubber sample, S2, determining a sample residual mass ratio Masstransition corresponding to a TGA transition point on the thermogravimetric curve and a final sample residual mass ratio Massfinal on the thermogravimetric curve, and S3, determining equivalent running time of the silicone rubber sample according to a predetermined relation among the equivalent running time of the silicone rubber material, Masstransition and Massfinal. The invention further discloses a judgment method of equivalent running time of a device in a grid system. With the adoption of the judgment method of the equivalent running time, a measurement result directly reflects an aging degree of the silicone rubber material; a measurement method is simple; an influence of a human factor is low; and the accuracy is high.
Description
technical field [0001] The invention relates to a method for judging the equivalent running time of silicone rubber materials based on thermogravimetric analysis. Background technique [0002] Silicone rubber materials are widely used insulating materials in power grid systems. Devices and products made of silicone rubber materials include but are not limited to composite insulators, anti-pollution flashover coatings, cable terminal accessories, etc. However, silicone rubber is an organic polymer material, which is susceptible to aging due to external environmental stress during long-term operation. High temperature vulcanized silicone rubber is the most widely used insulating material in power systems. Some high-temperature vulcanized silicone rubber insulation materials have poor aging resistance due to the raw materials or poor craftsmanship used. Contents of the invention [0003] The main purpose of the present invention is to overcome the deficiencies of the prior ...
