Description
Technical field
The utility model is involved in a kind of gas sample collector, particularly relates to the SF6 gas sample collector in container or the electrical equipment technical field.
Technical background
Because sulfur hexafluoride (SF
6) be nontoxic, colourless, tasteless at normal temperatures, chemical property is very stable, has excellent insulation arc extinguishing electric property, so the present electric sulfur hexafluoride (SF that more and more pays attention to
6) use.But sulfur hexafluoride gas through corona, spark and arcing, also can produce multiple poisonous, corrosive gas and solid decomposition product in electrical equipment, as: fluoridize thionyl, fluoridize inferior acyl, sulfur tetrafluoride etc.So, to containing sulfur hexafluoride (SF
6) the electric use of the gas detection of must taking a sample, guarantee the safe operation of equipment.Yet, to electrical equipment or container SF
6Sampler remains a vacancy at present, and this vacancy is for electrical equipment or container SF
6Gas uses and causes many inconvenience.
The utility model content
The purpose of this utility model is, in order to solve at present to electrical equipment or container SF
6The vacancy of sampler reaches sulfur hexafluoride (SF in the electrical equipment
6) accuracy that gas sample detects, guarantee that the safe operation of equipment provides a kind of SF
6The SF6 gas sample collector.
For reaching the technical solution that above purpose adopts be:
The SF6 gas sample collector, its design feature is: sampler mainly contains pipeline and is connected in electrical equipment, vacuum pump, sampling jar output unit and emptying composition is set, described electrical equipment is provided with valve switch output, valve switch is connected in an end of pressure vacuum gauge, the manometric other end is connected in sampling jar output unit that is provided with valve switch and the emptying setting that is provided with valve switch, in emptying the place ahead is set and is provided with the vacuum pump that connects valve switch.
The utility model can also adopt following measure to reach:
Be provided with reduction valve between electrical equipment and the pressure vacuum gauge.
Electrical equipment respectively is provided with fast connector with the sampling jar output unit and is connected with flexible pipe (7).
The pipeline connected mode of sampler all adopts tapered being tightly connected.
Emptying is set to connect the pipeline of valve switch.
The utility model has the advantages that:
1, the utility model is owing to be provided with in electrical equipment, valve switch, vacuum pump and emptying and respectively be provided with valve switch between the connection, so in emptying with more convenient and swift when finding time, the raising service efficiency.
2, pipeline of the present utility model connects the tapered mode that is tightly connected that all adopts, and assurance equipment (0.1MPa) and under the pressure (1MPa) can not leak, improve the security performance of sampling equipment in vacuum.
3, the utility model has adopted vacuum pump, the emptying before can carrying out more for a full due finding time in the electrical equipment evacuation system, and it is more accurate that sampling is detected, and more can guarantee the safe operation of equipment.
