The fixture of docking.
Background technique
SF6 gas has nontoxic, non-combustible and good insulation characterisitic, dielectric strength as a kind of insulating gas
It is much higher than traditional insulating gas, and has good arc-extinguishing, therefore is widely used in SF6 electric appliance.Due to SF6 gas valence
Lattice are expensive, and under the action of electric arc, electric spark and corona discharge, can decompose generation toxic substance.
Therefore, either SF6 electrical equipment is inflated, the recycling of tonifying Qi or gas, it should be in stringent operation
It is carried out under environment.
Currently, traditional operational method is, when tonifying Qi, gas cylinder connects pressure reducing valve in connecting pipe to the direct tonifying Qi of equipment.
It is noted that the pipeline that tonifying Qi uses needs drying, cleaning.First use the pressure of 0.1MPa to duct cleaning 5 to 10 seconds when tonifying Qi, then
To equipment tonifying Qi.The micro- pressure difference greater than pressure (generally higher than 0.1MPa) in equipment of cylinder outlet decompression meter pressure is mended when tonifying Qi
Gas, tonifying Qi to the above 0.02MPa of rated pressure value.Tonifying Qi can be stopped to pressure after ten minutes is unchanged by standing observation 5
Operation.Pressurizing valve (being located at SF6 electrical equipment one end) is first closed, SF6 gas cylinder valve (is located at SF6 gas cylinder end).Finally shutdown is set
Standby valve, removes pipeline.
The process of gas recycling is substantially above-mentioned reverse process, is repeated no more.
In inflation, tonifying Qi or gas recycling operation process, since SF6 gas is harmful to the human body, for example, sucking is excessive
Also it can cause to be choked to death to die, so needing to guarantee zero leakage.Currently, in the actual operation process, pressurizing valve and SF6 bottle valve
Butt Section between door, the temporary toxic gas for having part in inside, can quickly leak, although being unlikely to cause stopping up for personnel
Breath, still, really exerts a certain influence to the health of human body of operator, such as cause the defect of certain local functions.
