SF6Gas is widely used in the GIS device of urban distribution network substation with its excellent insulation and arc extinction performance
On.But work as SF6When electrical equipment leaks, the SF that leaks out6Gas and its decomposition product are gathered to indoor low layer space,
Ischaemia is caused, meanwhile, it include to pacify there are many noxious gas component to the life of the staff entered the room in decomposition product
Serious danger is constituted entirely, so industry provides SF indoors6In electrical equipment workplace, it is necessary to which online SF is installed6-O2
Leak supervision alarm, to SF in real-time monitoring environment6The content of gas and oxygen.At present about sulfur hexafluoride gas
The technical report of leakage warning device, such as the self-calibration GIS room sulfur hexafluoride of Patent No. " CN201410192175.7 "
Gas leakage monitoring alarming device, including online sulfur hexafluoride gas leakage monitoring host, gas-monitoring sensing unit, pneumoelectric connect
Device, controller of fan, human body infrared switch, combined aural and visual alarm and GPRS transmission module are connect, is remotely connected by GPRS transmission module
Central processing unit and remote control center are connect, in the case where Remote triggering, controls online sulfur hexafluoride gas leakage monitoring master
The central processing unit of machine sends order；GIS room sulfur hexafluoride gas can be detected by gas-monitoring sensing unit leak feelings
Condition, when carrying out the calibration of gas-monitoring sensing unit, remote control center sends self-test order, central processing to central processing unit
Device sends signal to relay, and control electrical ball valve successively calibrates sulfur hexafluoride and oxygen, gas-monitoring sensing unit
By calibration, the Zero drift in main amplifier of sensing unit is overcome, guarantee the accuracy of detection.Defect is: existing gas sensor is equal
It is exposed in air or its surface is only covered with filter screen, after longtime running, gas sensor surface or filtering net surface easily quilt
Dust covering, air cause measurement performance to decline to sensor surface diffusion hindered；In addition, sensor calibration uses SF6Gas, O2
The substances such as gas are only capable of carrying out sensor zero point correction, rather than SF6/O2The gamut concentration of gaseous mixture verifies.
Summary of the invention
The object of the present invention is to provide one kind can be cleaned to gas sensor surface, realizes SF6/O2Gaseous mixture
