 An overview of gas leak quantitative alarm system, is based on the current power system emphasizes the situation of production safety, personal health and safety protection in power distribution equipment installed SF6 equipment room staff designed, developed smart online testing system. It is mainly to detect SF6 gas content and oxygen content in the air, when excessive levels of SF6 gas in the environment or hypoxia, in real time alarm and automatically turn on the fan for ventilation, control the electronically controlled switch room door lock closure, and has a temperature and humidity detection, the working status of the voice prompts, remote alarm, and many other rich features. 



 Second, the main function 

 1, the SF6 gas content in the environment, quantitative detection. 

 SF6 gas content exceeded the alarm. 

 3, the oxygen content in air detection. 

 4, hypoxia alarm. 

 5, oxygen or SF6 excessive levels of forced air ventilation functions. 

 6, manually set the alarm point. 

 7, environmental temperature and humidity detection display. 

 8, regular exhaust function. 

 9, the fixed-point acquisition. 

 10 Forced ventilation function. 

 11, the last exhaust time display. 

 12, real-time display of various parameters. 

 13, SF6, of O2 content curve analysis function. 

 14, data reporting capabilities. 

 15, the historical data query functions. 

 16, infrared detection prompts. 

 17, optional wireless alarm. 

 18, optional toxic gases (such as CO, CH4, H2S) content monitoring. 

 19, an optional external input signal interface, the input signal from the smoke probe, door switches, etc.. 

 20, optional output interface, automatic 119 fire alarm, start / stop the dehumidifier, such as electronically controlled door a number of intelligent control functions. 

 21, optional digital SF6 density relay combination of network, composed of a full range of SF6 gas leakage monitoring system. 

 22, optional remote network monitoring system operation state, the direct control of the host or the operation of the transmitter. 

 Third, technical indicators 

 1, the working environment: 

 1) Temperature range: -10 ℃ ~ 50 ℃; 

 2) Humidity range: ≤ 95% RH; 

 3), seismic rating: 7 degrees; 

 4), Atmospheric pressure: 86kPa ~~ 106kPa; 

 2, SF6 measure: 

 1) Measuring range: 0 ~ 30000ppmv; 

 2), alarm point: can be set within the measuring range, the default 1000ppmv; 

 3), error: ± 5% FS; 

 4), the repeatability error: <5% FS; 

 5) Zero drift: <5% FS; 

 6) Span drift: <5% FS; 

 3, oxygen measurement indicators: 

 1), detectable concentration: 0 ~ 25%; 

 2), oxygen concentration alarm points: 18%; 

 3), oxygen measurement accuracy: <0.4%, O2 21%.
