Abstract
The invention relates to a drying chamber of an SF6 micro water tester. The drying chamber comprises a sampling air chamber, a drying air chamber, an isolation pipe, a rear end cover and a handle, which are located on a same horizontal center line. The sampling air chamber is connected with the handle through a fixed orifice. The drying air chamber coats the isolation pipe. The isolation pipe coats the sampling air chamber. The open end of the rear end cover is connected with a precise dew point transducer. When the drying chamber works, SF6 gas is injected into the sampling gas chamber, and a micro water dew point value is detected; and when the drying chamber is in a standby or storage state, the handle is rotated, and the sampling air chamber is communicated with the drying air chamber via the isolation pipe so as to maintain dryness of the sampling air chamber. According to the invention, switching of the states of the drying chamber of the SF6 micro water tester is convenient to operate; when the drying chamber is in the standby or storage state, the drying chamber maintains dry in real time without pre-charging of gas, so testing efficiency of the SF6 micro water tester and reliability and stability of test data are effectively improved.
