1) Decomposition under the action of electric arc;
2) Decomposition under corona, spark and partial discharge;
3) Catalytic decomposition at high temperatures.
The main manifestations of SF6 gas decomposition products are:
1) Pure SF6 gas is non-toxic, but it produces many kinds of toxic, harmful, corrosive gases and solid decomposition after decomposition.
2) These gases are mainly thionyl fluoride (SOF2), sulfuryl fluoride (SO2F2), sulfur tetrafluoride (SF4), sulfuryl tetrafluoride (SOF4), disulfide decafluoride (S2F10), disulfide oxydecafluoride (S2F10O), etc.; The main solid decomposition products are copper fluoride (CuF2), difluorodimethylsilicon [Si (CH3) 2F2], aluminum trifluoride (AIF3) powder, etc.
