Description
Technical field
The present invention relates to the electronic instrument technology field technical field, particularly a kind of sulfur hexafluoride analyte tester.
Background technology
Sulfur hexafluoride (SF
6) be widely used in the high voltage electric equipment because of its superior insulation, arc-extinguishing medium.Along with developing rapidly of domestic power industry, from eighties of last century after the 80's, SF
6Electrical equipment replaces traditional oil-filled electrical equipment gradually, for safety and stability, the economical operation of electric system obtains good effect.But because equipment has influenced the normal operation of equipment, even led to a disaster in some defective that aspects such as design, manufacturing, installation and operation maintenance exist, therefore in time detect SF
6The inside electric appliance defective has very important meaning to the safe operation of assurance equipment and electrical network.Detect SF early
6Electrical equipment malfunction improves and sends out power supply reliability and judge SF
6Whether electrical equipment needs to overhaul is the major issue that power department is paid close attention to.
At present, the early diagnosis SF for how
6Electrical equipment malfunction, traditional electrical test method seems unable to do what one wishes sometimes.By detecting SF
6The content of other gases judges whether electrical equipment breaks down in the electrical equipment.Diagnosing electrical equipment malfunction with this, is following developing direction, and huge market potential and using value SF are arranged
6Decomposition product during the inside electric appliance fault mainly is sulfide and fluoride.Sulfide mainly contains sulphuric dioxide SO
2, sulfuretted hydrogen H
2S, SF
4, SO
2F
2, SOF
2Deng; Fluoride mainly contains HF, CF
4And metal fluoride.Remove sulphuric dioxide SO in the above-mentioned analyte
2, sulfuretted hydrogen H
2S and CF
4Outside toxicity was little, other all is violent in toxicity, and was few at the content of device interior, unstable again, wherein SF
4, SOF
2Deng again can hydrolysis producing stable sulphuric dioxide SO
2And HF, therefore, the sulphuric dioxide SO of detection
2Concentration is the total amount of directly decomposition and hydrolysate.Sulfuretted hydrogen H
2S is the characteristic component that solid insulating material decomposes, and just can produce when the fault energy is big.HF corrosivity is very strong, sensor costliness, life-span weak point, and the on-the-spot necessity that detects is not very big.CF
4Whether the 200 μ l/L content of having an appointment in new gas decompose if estimate insulating material with the added value of so big content, and its reliability just greatly reduces.Along with the widespread use of GIS, new detection method and the raising of detection means, SF
6The gas discharge decomposition component detects and analyzes and certainly will will become SF
6A kind of effective means of electrical equipment malfunction monitoring and diagnosis.Purpose as preventive trial is to detect inherent vice in early days, therefore there is no need at the scene also can not all analyze various pyrolysis products but not carry out comprehensive diagnos.
