Technical field
The present invention relates to a kind of power equipment easy to operate sulfur hexafluoride sample devices.
Background technology
Sulfur hexafluoride（SF6）Gas has one-hundred-year history, it is France two chemists Moissan and Lebeau in 1900
The artificial inert gas of year synthesis, before and after 1940, US military uses it for Manhattan project（Core is military）.Nineteen forty-seven provides
It is commercial.Current SF6 gases are mainly used in power industry.
Sulfur hexafluoride has good electrical insulation properties and excellent arc extinction performance.Its electric strength is under same pressure
2.5 times of nitrogen, breakdown voltage are 2.5 times of air, and arc extinguishing ability is 100 times of air, are that one kind is better than air and oil
Between super-pressure insulating dielectric materials of new generation.Sulfur hexafluoride is with its good insulation performance and arc extinction performance, such as：Breaker,
High-tension transformer, sealing gland close combined capacitor, hv transmission line, mutual inductor etc..
In SF6 breakers, the necessary strict regulations of water content of SF6 gases are no more than standard.Water can be decomposed with electric arc
SF4 in object generates hydrofluoric acid（H2O+SF4 →SOF2 +2HF）And corrosion material.When moisture reaches saturation, can also
In insulating part surface condensation, significantly reduce dielectric strength or even cause creeping discharge.Operating experience and upper review analysis all tables

The similar power equipment of producer, therefore poor universality cause the different sulfur hexafluorides for needing to carry different manufacturers during inspection to fill
Equipment, it is very troublesome；3rd, the power equipment for filling sulfur hexafluoride is generally located on tower bar or substation top, and distance is higher, must
Must ascend a height operation；It is general there are two types of sample mode when being sampled at present using bulky sulfur hexafluoride filling equipment, the first
Exactly sulfur hexafluoride filling equipment is lifted at power equipment sampling, needs the auxiliary of more manpower or hanging device at this time；The
Two kinds of modes are that sulfur hexafluoride filling equipment is placed on ground, and adopting for sulfur hexafluoride is carried out in a manner that laying samples pipeline
Sample；Though the second way does not need to more manpower or hanging device auxiliary, extended pipeline can store greatly after sampling
Sulfur hexafluoride is measured, and the sulphur hexafluoride emission in pipeline must be fallen when carrying out next power equipment sampling, to avoid right
Next time, sampling impacted, and therefore, the shortcomings that second way is exactly that a large amount of sulfur hexafluorides is not only caused to waste（Sulfur hexafluoride
It is expensive）, and environmental pollution can be caused（Sulfur hexafluoride is very big to human injury）.
