Abstract

The invention discloses a method and a system for establishing a mid-infrared spectrogram library of silicone rubber for a composite insulator, and belongs to the technical field of research on materials for high-voltage power transmission lines. The method comprises the following steps: determining a monochromatic spectral line of a background peak within an effective duration; acquiring an infrared spectrogram of a silicone rubber for a target composite insulator according to the ratio, and taking the infrared spectrogram as a sample wafer; carrying out mid-infrared infrared spectrum test on the sample wafer preset times, recording a variance graph and a mean graph of an infrared spectrum graph, determining a standard deviation graph according to the variance graph, selecting points with high stability in the standard deviation graph as identification feature points, and taking a test result of the identified feature points as the mid-infrared spectrum graph; and establishing a mid-infrared spectrogram library for the variance graph, the mean value graph and the mid-infrared spectrogram. According to the invention, a proper middle-infrared spectrum silicone rubber formula map library can be established, and unknown sample wafers can be identified by using the formula map library.

Description

technical field [0001] The invention relates to the technical field of research on materials for high-voltage transmission lines, and more specifically, relates to a method and system for establishing a mid-infrared spectral library of silicone rubber for composite insulators.
