Description
Technical field
The utility model relates to a kind of gas-detecting device, specifically a kind of indoor SF of transformer station
6Gas online monitoring alarm system.
Background technology
SF
6Be synthetic in 1900 by two french chemist Moissan and Lebeau.From the sixties in last century, SF
6Be widely used in the primary cut-out and converting equipment in the bulk of worldwide electricity industry as extremely superior insulation, arc-extinguishing medium.Now, SF
6Gas almost becomes insulation unique among high pressure, extra high voltage circuit breaker and the GIS and arc-extinguishing medium.
Pure SF
6Gas is colourless, tasteless, do not fire, and chemical property is stable especially at normal temperatures, is more than 5 times of air specific weight.But in electric system, because SF
6Gas mainly serves as insulation and arc-extinguishing medium, under factor affecting such as electric arc and shelf depreciation, high temperature, and SF
6Gas can decompose.Its analyte generates corrosivity electrolyte, especially some high toxicity analyte after meeting moisture content, like SF
4, S
2F
2, SOF
2, HF, SO
2Deng, cause dizziness and pulmonary edema like a large amount of suction people cognition, even stupor and dead.
Indoor what seal relatively, since sluggish in air circulation, SF
6And analyte adds SF in indoor deposition
6Gas is colourless, tasteless, thereby tour, maintainer are produced great harm.After GIS (gas insulated transformer substation) produces leakage, SF
6Gas accumulates in the low sheaf space in terrace top, causes local anoxic, the people is suffocated and causes a serious accident.
The utility model content
To above-mentioned deficiency, the utility model provides a kind of transformer station indoor SF
6Gas online monitoring alarm system, it not only can detect the indoor SF of transformer station in real time
6Concentration is also reported to the police, and can be according to SF
6Concentration is opened blower fan automatically and is carried out air regulation.
For addressing the above problem, the utility model adopts following technical scheme: the indoor SF of a kind of transformer station
6Gas online monitoring alarm system; It is characterized in that; Comprise central processing unit, gas-detecting device, human body sensing device, fan controller and acoustic-optic alarm, said gas-detecting device, human body sensing device, fan controller and acoustic-optic alarm are connected with central processing unit respectively; Said gas-detecting device comprises the gas collecting controller and as doing an acquisition terminal, said acquisition terminal is connected with the gas collecting controller respectively; Wherein, the acquisition terminal of said gas-detecting device is separately positioned on the indoor different places of transformer station, in order to gather SF
6And O
2Gas concentration information also sends to the gas collecting controller, the SF of said gas collecting controller to being gathered
6And O
2Send to central processing unit after gas data information is handled, said central processing unit is according to collecting SF
6And O
2Gas density compares with the setting threshold values, if SF
6And O
2Gas density exceeds setting threshold values scope then reports to the police to acoustic-optic alarm transmission warning message, sends the work order of startup blower fan to fan controller simultaneously and ventilates; Said human body sensing device is arranged on the indoor porch of transformer station, if the personnel that detect get into, then sends relevant information and gives central controller, and said central controller then starts blower fan work and ventilates.
Further, said human body sensing device comprises the infrared human body induction sensor.
Further, also comprise the humiture pick-up unit, said humiture pick-up unit is connected with central processing unit.
Further, also comprise the upper level supervisory system, said upper level supervisory system is arranged on Surveillance center.
The beneficial effect of the utility model is: after adopting said structure, this system can be to the indoor SF of transformer station
6Combined electric appliance equipment SF
6Oxygen level is monitored in real time in the leakage situation of insulating gas and the air, has realized unattended operation transformer station and switch gear room are monitored in real time, has improved the efficiency of management, improves and safeguards system.The utility model is through detect the indoor SF of transformer station in real time
6Concentration is also reported to the police and automatic vent carries out air regulation automatically, has not only improved the security of unattended operation transformer station operation, and reliable guarantee is played in daily tour and maintainer's personal safety.
