6Decomposed can occur in gas, and its decomposition product can produce some extremely toxic substances after running into moisture, as fluoridizes thionyl (SOF
2), sulfur tetrafluoride (SF
4), bifluoride sulphur (SF
2) etc., similar these extremely toxic substances are even if trace also can cause people's unnatural death.When using with SF
6When gas in use leaks for insulation and the cubicle switch of arc-extinguishing medium, the SF that leaks out
6Gas and analyte thereof can gather toward indoor low layer space, and are difficult for distributing, and cause local anoxic and band poison, and the safety that enters indoor maintenance and the personnel of tour is consisted of grave danger.
In recent years, along with China's electric power, railway construction develop raising with technical equipment rapidly.Guarantee that the electric power system safe operation becomes the most important thing in the work.And SF
6Equipment is extensively used with its excellent insulating property and arc extinction performance again, has almost become employed unique insulation and arc-extinguishing medium in middle pressure, high pressure and the ultra-high pressure switch.How strengthen management SF
6Equipment use and ensure SF
6The safe operation of equipment becomes the emphasis in the maintenance.Because SF
6Be the gas that newborn institute is not familiar with by people, detection method and detecting instrument are also immature.This will bring the larger responsibility of service work personnel and pressure.Therefore, the monitoring system that needs a kind of sulfur hexafluoride gas of design.
