Experimental research on sealing performance of sulfur hexafluoride electrical equipment under low-temperature environment

摘要：

　　It is discovered that the sealing performance of the sulfur hexafluoride electrical equipment worsens under low temperature,but research in the aspect is reported rarely when corresponding measures are adopted for improving the sealing performance of electrical equipment.Therefore,sealing and leakage test of sulfur hexafluoride electrical equipment was implemented under low-temperature environment according to the analysis on gas sealing methods of sulfur hexafluoride electrical equipment.Causes of gas leakage of sulfur hexafluoride electrical equipment under low temperature environment were analyzed according to test results.Effective measures were proposed for improving the gas sealing performance of the equipment,thereby providing valuable reference for gas sealing design,installation,operation maintenance and failure analysis of sulfur hexafluoride electrical equipment under low-temperature environment.
