Method and device for the detection of SF6 decomposition products |
| 摘要 |
This invention is in the field of gas detection for sulphur hexafluoride (SF<SUB>6</SUB>) gas decomposition products, particularly for the detection of thionyl fluoride (SOF<SUB>2</SUB>) and sulphur dioxide (SO<SUB>2</SUB>). The invention relates to a novel portable handheld instrument that can readily detect SOF<SUB>2</SUB>, SF<SUB>4 </SUB>and SO<SUB>2 </SUB>in SF<SUB>6 </SUB>gas filled electrical equipment and in air. An apparatus for detecting SF<SUB>6 </SUB>decomposition products comprising: (a) an inlet for receiving SF<SUB>6 </SUB>gas containing SOF<SUB>2 </SUB>or SF<SUB>4</SUB>; (b) A chamber connected to the inlet and containing a catalyst which converts SOF<SUB>2 </SUB>or SF<SUB>4 </SUB>into SO<SUB>2</SUB>; and (c) an SO<SUB>2 </SUB>detector connected downstream of the chamber.
