Gas analysis and testing system for sulfur hexafluoride with low-temperature and constant humidity

The invention discloses a gas analysis and testing system for sulfur hexafluoride with a low-temperature and a constant humidity, and relates to the field of the electric test. At present, the changesof the temperature and the humidity have a significant effect on the test result of a gas analysis and testing instrument for the sulfur hexafluoride, and the gas analysis and testing instrument cannot work normally especially in high temperature and low humidity test environment in the summer. The gas analysis and testing system comprises a box body, a box door located in front of the box body,a physical cooling module arranged in the box body, a temperature measuring device, a constant humidity device, a testing instrument, and a sulfur hexafluoride inflatable device communicated with thetesting instrument through a pipeline. The box body is composed of double-layer plates, and insulating materials are filled between layers of the plate; a hollow support is arranged in the box body, and divides the interior spa
