SF can be depended greatly on6The purity of gas and density, so, to SF6The supervision of the detection of gas purity and density shows
Obtain particular importance.If using ordinarily manometer to monitor SF6The leakage of gas, that will be hard to tell is to let out owing to being truly present
Leakage still causes SF due to variation of ambient temperature6The pressure change of gas.In order to be able to the purpose reaching often to monitor density, state
Family's standard regulation, SF6Electrical equipment should install Pressure gauge or SF6Air density meter and density monitor.Pressure gauge or SF6Gas
Density meter has been supervision effect, SF6Density monitor has been control and protective effect.
Due to SF before6Density monitor is to be directly installed on SF6On equipment cavity, to original SF6Density monitor
Must dismantle when verifying, frequent dismounting can increase the possibility of gas leakage, and because mechanical damage causes SF6Density relay
Device interface even SF6Electrical equipment interface thoroughly damages, and causes very big economic loss.Meanwhile, because SF dismantled by needs6Density continues
Electrical equipment causes site examining and repairing operating efficiency extremely low.Secondly, there is the three-way connection of valve control function because not having error locking proof function,
After desk checking completes, easily forget recover valve to properly functioning duty, or scene by other uncorrelated personnel mistake
Operation valve control switching knob causes SF6Density monitor departs from SF6Electrical equipment monitor state, brings great potential safety hazard.
