The invention relates to the field of electric power auxiliary equipment, in particular to an automatic gas taking mechanism, a gas detection device and an SF6 gas online detection system so as to solve the problems of low automatic detection degree and long detection result input time consumption of the gas taking and detection of the existing SF6 gas decomposer and humidity detection work. The automatic gas taking mechanism comprises joints, a first electromagnetic valve, a gas taking unit, a first pipeline and a second pipeline, wherein one end of the joint is connected with an equipment gas taking opening; the other end of the joint is connected with the first electromagnetic valve; one side, far away from the joint, of the first electromagnetic valve is connected with the first pipeline; one end, baking to the joint, of the first pipeline is communicated with a gas inlet of the gas taking unit; one end of the second pipeline is communicated with a gas outlet of the gas taking unit; and the other end of t
