Description
Technical field
The present invention relates to field of gas treatment, in particular to a kind of sulfur hexafluoride alarm processing method and device.
Background technology
At present, with the fast development of urbanization, big city population is more intensive, and skyscraper stands in great numbers, and electricity consumption is drastically
Increasing, number transformer is also being continuously increased, and traditional large capacity oil-immersed transformer oil mass is big, once because failure is caught fire, it will
Serious threat is formed to the security of the lives and property of skyscraper and people.Therefore, six-component force balance transformer is in last century
It is had been widely used after the eighties in Urban Underground substation of China.Compared with traditional filling transformer, SF6 transformations
Device has clear advantage：Due to the non-combustible of SF6 gases and not combustion-supporting property, SF6 gases do not have the potentially possible of fire, and noise
It is low, it is particularly suitable for using in bustling commercial center and densely populated residential block.Especially those are populous, land used is nervous
High-Density Urban Area all have underground substation, wherein being exactly that the six-component force balance applied becomes electric appliance.
SF6 gas-insulated performances are although superior, still, stringent quality must be carried out to it according to related regulatory requirements and is supervised
It superintends and directs and safety management.This is because SF6 gases in its production process or under the action of the high energy factor, can decompose generation
Several toxic or even hypertoxic, strong corrosive objectionable impurities, when there are moisture, air (oxygen), electrode material, equipment and materials in system
Deng, then can lead to the complication of decomposable process, cause the value volume and range of product of decomposition product significantly to increase, harmfulness also significantly plus
Greatly.A large amount of leakages occur for six-component force balance transformer when urgent catastrophic failure, and the common processing method of substation is to let out
After leakage alarm sends out warning, staff should withdraw rapidly scene, if being happened at indoor location place, should open room ventilation
Device.Do not wear a gas mask or positive-pressure air respirator personnel no admittance.Only by sufficient natural exhaust or by force
Air draft processed, when monitoring that SF6 gases, oxygen content are up to standard by SF6 leakage monitoring systems, personnel are just accurate to be entered.
If but the generation leakage failure of the underground substation six-component force balance transformer positioned at down town, above-mentioned processing
Counte-rplan are very improper, are densely populated as the aerial part of Beijing Xidan underground substation has an area of within 600 meters
Area, if still selecting the measure of ventilation after Sudden Leakage failure, it will cause serious consequence, SF6 gases and equipment are transported for a long time
The complicated decomposition product that row produces in the process will pollute ground air, SF4, SOF2, SF2, SO2F2, HF etc. and be
Toxicity and the extremely strong compound of corrosivity dough figurine group can generate body harm, and it is possible that cause pernicious personal injury over the ground.
In addition, again since requirement of China's power department to power failure is catastrophic failure, emergent management is powered in time.
It once, be in a short period of time to being leaked in the interior space so underground substation six-component force balance transformer catastrophic failure
Sulfur hexafluoride gas recycled, and store it in and subsequent processing is waited in container, to make gas leakage accidents live
It is rapidly achieved the state that can be repaired.
But there is presently no relevant Emergency recovery device, early warning and Emergency recovery after more happening suddenly without leakage accident
Linked system.
Sulfur hexafluoride is effectively located for that can not be realized when sulfur hexafluoride leakage accident is faced in above-mentioned the relevant technologies
The problem of reason, currently no effective solution has been proposed.

I/O input terminals, start Emergency recovery flow, fall shutter door.
It that is to say, above-mentioned sulfur hexafluoride alarm processing method provided in an embodiment of the present invention can pass through the SF6 of transformer chamber
The real-time monitoring of leakage monitoring sensor sends out three kinds of alarm signals to the I/O input terminals of PLC hosts：SF6 gases it is current dense
It is red alarm information during degree >=1000PPM, the alarm when red on corresponding transformer chamber doorway dodges, and adjoint voice alarm,
For staff to be prompted not pay attention to personal safety close to the scene of the accident.Alarm is transmitted to PLC in the form of switching signal
The I/O input terminals of host, start the recovery command for recycling SF6, fall shutter door.When the existing concentration of SF6 gases is more than
500PPM, but no more than 900PPM when be generated as yellow alarm information, the bright sudden strain of a muscle of alarm amber light on corresponding transformer chamber doorway, and
With voice alarm, alarm is transmitted to the I/O input terminals of PLC in the form of switching signal, closes recovery command, starts strong
Power exhaust system.As the existing concentration ＜ 500PPM of SF6 gases, meanwhile, it is corresponding during the oxygen content ＞ 18% of above-mentioned presumptive area
The alarm green light on transformer chamber doorway dodge, and with voice alarm, indicating alarm has released, and staff can enter existing
Field construction, alarm are transmitted to the I/O input terminals of PLC in the form of switching signal, close strength exhaust system, lift shut-off
Door.
In an optional embodiment of the present invention, after being handled according to warning message presumptive area, this hair
The sulfur hexafluoride alarm processing method that bright embodiment provides can also include：To what is recycled in the case where starting recovery command
SF6 carries out purification processes.It that is to say, after the completion of a large amount of gas leakage Emergency recovery work occurs in transformer chamber, operation maintenance personnel can
Repair and maintenance work is practiced, and the SF6 gases of recycling are purified in reasonable time.It specifically can be lithium by pressing
Sulphur report leaks the purification button of early warning recovery control system, opens gas classification module, then presses reservoir gas purification button,
After confirming button is pressed, it can both perform and recycling carried out to the SF6 of leakage and the SF6 gases of storage tank purify.
In addition, after warning message is generated according to existing concentration, at sulfur hexafluoride alarm provided in an embodiment of the present invention
Reason method can also include：Warning message is stored, in case post analysis is called.
Wherein, warning message can pass through data processing and control operation accordingly, then pass control operation result
Host computer is transported to, and is shown inside the warning message of host computer and history warning message, is checked in case calling.In sulfur hexafluoride
By upper while report leakage early warning recovery control system starts Emergency recovery instruction (that is to say the recovery command in context)
The short message transmitter of position machine sends SMS to chief leading cadre, is prepared so that it is prompted to carry out trouble hunting in advance.
