The requirement of power induction system is more and more higher.Electric power resource, when long distance delivery, will use high pressure defeated to reduce energy consumption
The method of electricity.In novel high-pressure, supergrid, SF6 gas, with electrical insulating property and efficient arc extinguishing character, gradually replaces insulation
The dielectrics such as oil, air, are applied in high pressure, ehv power transmission equipment.The high-voltage electrical equipment using SF6 gas has
The features such as noise is low, volume is little, maintenance workload is little, obtain the whole nation and are widely popularized and apply.The most metal enclosed combination electricity
In device (GIS).
Along with increase and the growth of the equipment operation time limit of GIS usage amount, the accident quantity caused because of SF6 leakage is the most obvious
Raise, badly influence the efficiency of transmission of the electric power energy of China.Although the GIS using SF6 gas requires annual slip
Less than 0.1%, but, equipment application is often extremely difficult to this index.Tool statistics is to the end of the year 2010, SF6 gas high pressure electricity
Device equipment year, accident rate was about 0.4%, year fault rate be about 0.8%.Relatively early to use the Guangdong of SF6 gas high pressure electric equipment
As a example by province, during using 15 years SF6 gas high pressure electric equipments, there occurs that more than ten play electric power accident, accident band the most altogether
The economic damage directly or indirectly come is the hugest.
What the high-tension electricity equipment using SF6 gas was worried most reveals, exactly if leakage point, SF6 gas occurs in equipment
Leak, can cause the consequence of the following aspects:
The first, make gas pressure decline, cause arc extinguishing and decreasing insulating；
The second, the moisture in air can cause equipment moisture to raise from leak access arrangement, accidents caused, sternly
Chopper can be caused to explode during weight；
3rd, pure SF6 gas is gas that is a kind of colourless, tasteless, nontoxic and that do not fire.Even if temperature high to when 500 DEG C also
Will not decompose, but when coexisting with metal material, be possible to decompose when 200 DEG C, spark discharge and corona also can in addition
Make SF6 decompose the multi-products that dissociates, SF4, SF2, S2, F2, S, F etc., this type of analyte often contains severe toxicity, even if micro-
Amount, also humans and animals can be worked the mischief；
4th, SF6 is heavier than air, it is easy to assemble in lower, after reaching finite concentration, if staff enters room
In, cerebral anoxia can be caused, make people suffocate and cause a serious accident；
5th, SF6 gas is one of six big greenhouse gases, and excess emissions is understood heavy damage atmospheric ozone layer, increased the weight of air
Greenhouse effect, destroys ecological environment.
Therefore, research and development GIS switch gear room ambient intelligence wireless supervisory control system, real-time precision measurment GIS indoor SF6 concentration, when
During SF6 concentration over-standard, timely warning reminding is run or maintainer's urgent danger prevention, and takes measures in time to solve leakage, just becomes
Ensure the important topic of power generation safety
