Problems solved by technology

In the application, we found that after the test is completed, there will be a lot of sulfur dioxide poisonous gas inside the box used for temporary storage of gas by the detector. Since the inspectors generally use hand-held inspections, and the inspectors are very close to the detector, long-term operations will be affected. Sulfur dioxide poisoning

Abstract

A gas detection tubefor a discharge fault of a combined electric appliance comprises a box body, the box body is of a cuboid-shaped shell structure with an opening in the lower portion, and a gas detector is installed at the opening end of the box body. Through combination of a fan, a second valve, a third valve, a gas storage bag and the like, after test is completed, a detector can close the second valve at first and open the fan at the same time, so that the fan pumps outside air into the box body, and therefore, on one hand, poisonous gas left in the box body is diluted, on the other hand, the poisonous gas is pumped into the gas storage bag to be stored; then the third valve is closed, so that the poisonous gas is stored in the gas storage bag and does not escape, and the toxicity of sulfur dioxide to detection personnel is reduced.

Description

technical field [0001] The invention relates to a detection tube, more precisely a gas detection tube for discharge faults of combined electric appliances. Background technique [0002] When a discharge fault occurs in the gas chamber of the combined electrical appliance, SO2 and other gases will be generated. The gas composition and content in the gas chamber can be judged by the gas composition meter, and the discharge fault gas chamber can be accurately detected. In the application, we found that after the test is completed, there will be a lot of sulfur dioxide poisonous gas inside the box used for temporary storage of gas by the detector. Since the inspectors generally use hand-held inspections, and the inspectors are very close to the detector, long-term operations will be affected. Sulfur dioxide is poisonous. Contents of the invention [0003] The object of the present invention is to provide a gas detection tube for combined electrical discharge faults, which can...
