Description
Technical field
This utility model relates to harmful field of gas treatment, in particular to a kind of SF6Gas gathering system.
Background technology
Along with the continuous propelling of Urbanization Process In China, standing in great numbers in urban skyscraper, population is the most intensive, power consumption, transformator
Quantity is also being continuously increased.The oil mass of Conventional mass oil-filled transformer is relatively big, once catches fire the life to people because of fault
Property safety constitutes a serious threat.Therefore, six-component force balance transformator has been widely used in China city since the sixties in last century
Underground substation, city.
Compared with traditional filling transformer, due to SF6Non-combustible and the most combustion-supporting property of gas so that six-component force balance transformator does not has
There is the Potential feasibility of initiation fire, and its noise in running is low, particularly suitable at bustling commercial center and population
Intensive residential block uses.
SF6Although gas-insulated performance is superior, but it must be carried out strict quality surveillance and safety according to relevant regulatory requirements
Management.This is because SF6Gas in process of production or under the effect of the high energy factor, can decompose that generation is some poisonous even to be had
Severe toxicity, the objectionable impurities of severe corrosive.When system exists moisture, air (oxygen), electrode material, equipment and materials, can make
Obtaining catabolic process to complicate, cause catabolite value volume and range of product substantially to increase, hazardness strengthens.
SF6The harm of gaseous impurity mainly shows as toxicity and the corrosivity of catabolite.SF6Impurity in gas and catabolite
Middle acid substance particularly HF, SO2Existence can cause the corrosion of sulfur hexafluoride insulation electrical equipment material；The existence of moisture exists
Electric property may be caused under certain condition to deteriorate (the various electric arc analytes of sulfur hexafluoride gas and SF6Gas produces through hydrolysis
Fluohydric acid gas (HF) and sulphuric acid (H2SO4), some metal object and insulating part can be produced corrosiveness, and then leak, shadow
Ring the service life of electrical equipment), even cause serious equipment breakdown.And such as SF present in sulfur hexafluoride4、SOF2、
SF2、SO2F2, HF etc. be toxicity and the extremely strong compound of corrosivity, very big to harm, it is possible to cause the pernicious person
Accident.
But, owing to the workmanship of six-component force balance transformator, mounting process, aging, the blowing pressure of potted component etc. are former
Because causing SF in transformator6Gas leakage is difficult to avoid that.Once there is leakage failure in six-component force balance transformator, it is interior
Sulfur hexafluoride gas will escape in a large number, the SF leaked out6Gas and analyte thereof, in the accumulation of indoor low layer space, cause local
Anoxia and band poison, cause serious harm to the health entering indoor maintenance and the personnel of tour.
At present, when six-component force balance transformator occurs the emergencies such as a large amount of leakages, the common processing method of transformer station is: let out
After leakage alarm sends warning, staff should withdraw rapidly scene, if occurring in indoor location place, should open room ventilation
Device.Do not wear a gas mask or positive-pressure air respirator personnel no admittance, only through sufficient natural exhaust or pressure
Air draft, and through SF6Leakage monitoring system monitors SF6After gas, oxygen content are up to standard, personnel are just accurate to be entered.
Above-mentioned ventilation emptying process scheme is not suitable for being positioned at the underground substation six-component force balance transformer leakage event of down town
Barrier.If leakage failure still selects ventilation emptying measure will make SF after occurring6Gas and equipment During Process of Long-term Operation produce
Toxicity and the extremely strong complicated catabolite such as SF of corrosivity4、SOF2、SF2、SO2F2, HF etc. pollute ground air, over the ground
Dough figurine group produces body harm, and may cause pernicious personal injury.
Visible, underground substation six-component force balance transformator once Sudden Leakage fault, be in a short period of time to Interior Space
In between, the sulfur hexafluoride gas of leakage reclaims, and makes gas leakage accidents scene be rapidly achieved the state that can carry out rushing to repair.
