[0041] Example: such as Figure 1 to Figure 10 Shown; a method for identifying partial discharge characteristics based on the decomposition characteristics of sulfur hexafluoride gas, which includes: the method steps are as follows:
[0042] S1: Test SF 6 Whether the purity of the gas meets the standard, SF 6 Namely sulfur hexafluoride;
[0043] S2: detect SF 6 The impurity gas content in the gas;
[0044] S3: select SF 6 The characteristics of the decomposition components of the gas after partial discharge are detected and identified.
[0045] Check SF as described in step S1 6 Gas purity standards include: SF inspection 6 Whether the gas is damp or leaking; check SF 6 Whether the oxygen and moisture content in the gas exceeds the standard.
[0046] SF is detected in the step S2 6 The impurity gas content in the fresh gas mainly detects CO 2 Gas content, CF 4 Gas content, SO 2 F 2 Gas content and SOF 2 Gas content.
[0047] SF in step S3 6 The decomposition component characteristics aft...
