摘要：
UHV GIS spacer is a key insulator in the gas insulated switchgear, the concentration of stress may cause tiny flaws on the spacer which will lead to discharge on the spacer. In order to analyze the stress concentration on the GIS spacer when external stress acts, the ANSYS is applied to calculate the distribution of the stress and strain during the hydrostatic test. At the same time, the fiber Bragg grating is arranged on the surface of the GIS spacer based on the calculation to measure the strain of different positions in hydrostatic test. The results of measurement and calculation indicate that the worst stress concentration lies near the flange where the spacer has a small radius of curvature, and the cracking begins here. The experiment shows a similar result on the strain distribution with the calculation, which verifies that the calculation is an effective method to study the mechanical of GIS spacer. © 2018, High Voltage Engineering Editorial Department of CEPRI.
