Description
Technical field
A kind of gas sampling device is the utility model is related to, more particularly to one kind is used for SF6The novel sampling device of gas.
Background technology
SF6Gas is a kind of colourless, odorless, nontoxic and non-flammable gas under normal temperature, normal pressure, and chemical property is very steady
It is fixed, and there is good electrical insulation properties and excellent arc extinction performance.Therefore, it is widely used in the high pressure of power industry
Switch, high-power transformer, the insulating materials of high-tension cable and gas.
SF6The situation that moisture enters in gas mainly has two kinds：First, power equipment is in an assembling process, into element and
The moisture diffusion of inner surface of container is to SF6In gas；Second, when equipment poor sealing, the intrusion of outside moisture.These moisture
Exist generally in the form of water vapour, at a lower temperature, vapor condensable Cheng Lu is attached to piece surface, increases and edge occurs
The possibility of face electric discharge, and under electric arc or corona high temperature action, SF6Gas can decompose, and its analyte, which meets water, will generate strong corruption
Corrosion material, threat is produced to health.Such as SF6Trace moisture content is exceeded, will influence insulation and the arc extinction performance of equipment,
It is light then reduce SF6The service life of power equipment, heavy then damage equipment simultaneously trigger insulation fault.Therefore, SF is improved6Power equipment
The test accuracy rate of trace moisture content is significant.
At present, SF is caused6The reason for measurement of power equipment gas trace moisture content is inaccurate is generally divided into two kinds：Data
Cause measurement inaccurate in the presence of interference；Measured under the extreme weather environment such as high temperature, high humidity, low temperature inaccurate.Power system is for many years
Operating experience show, under extreme weather conditions, measure inaccuracy probability accounting highest.Easily there is following defect：
First, under summer high temperature high humidity environment, moisture enters instrument by pipeline so that measurement result is higher.
Second, under winter low temperature environment, SF6Volume is shunk after contract on cooling, and causes hydrogenesis to be adsorbed in equipment,
So that measurement result is relatively low.
Third, under thunderstorm season wet environment, easily cause measurement result higher.
Some sampling equipments are developed for this to solve the above problems, but existing sampling equipment still have it is certain
Defect, such as existing the sampler flow velocity of gas and amount of gas in air inlet and exhaust process is uncontrollable, is not easy to carry out
Accurately side view.
Utility model content
The purpose of this utility model is to provide the SF that a kind of carrying is convenient and inlet, outlet speed is controllable6Gas it is new
Sampler.
It is provided by the utility model this to be used for SF6The novel sampling device of gas, it includes the sampling bottle of both ends open
Be connected at sampling bottle both ends open, the air intake assembly and gas deflation assembly of air velocity can be adjusted.
The openend of the sampling bottle is equipped with internal thread, and air intake assembly and gas deflation assembly are threadedly connected to sampling bottle respectively
Both ends, junction scribbles fluid sealant.
The air intake assembly includes being connected to the intake valve of the openend of sampling bottle one and is communicated on intake valve valve pocket
Pressure gauge and inlet suction port, the reciprocating motion of air inlet valve core can adjust the intake velocity of inlet suction port.
The intake valve is Self-sealing valve, and shown inlet suction port is self-sealing joint.
The gas deflation assembly includes being connected to the air bleeding valve of the sampling bottle other end and the exhaust being communicated at air bleeding valve valve pocket
Joint.
The material of the air bleeding valve and exhaust joint is stainless steel.
The material of the sampling bottle, intake valve and inlet suction port is stainless steel.
The utility model will need to carry out the SF of micro- water test by air intake assembly when in use6Collect to band in sampling bottle
It is back under the completely qualified environment of test condition and is tested, reduces the influence of external environment, improves the degree of accuracy of test；And
The flow velocity of gas can be controlled when collecting gas and discharging gas, the controllability of measurement gas flow is improved, is easy to further carry
The degree of accuracy of height test.
Brief description of the drawings
Fig. 1 is the schematic front view of one preferred embodiment of the utility model.
Illustrate sequence number：
1-sampling bottle, 2-intake valve, 3-pressure gauge, 4-inlet suction port, 5-air bleeding valve, 6-exhaust joint.
Embodiment
As shown in figure 1, this of the present embodiment offer is used for SF6The novel sampling device of gas, it includes both ends open
Sampling bottle 1 and be threadedly connected to the air intake assembly and gas deflation assembly at sampling bottle both ends, threaded connection place scribbles fluid sealant.
Air intake assembly includes intake valve 2, pressure gauge 3 and inlet suction port 4, the valve of pressure gauge and inlet suction port with intake valve
Chamber is connected, and the intake velocity of inlet suction port is adjusted by the reciprocating motion of air inlet valve core, and bottle internal pressure is observed by pressure gauge
Power, in order to gas flow in regulating and controlling bottle, realize precisely sampling；Simultaneously in order to ensure seal while make it is simple and reliable for structure,
Intake valve selects Self-sealing valve, and inlet suction port selects self-sealing joint.
Gas deflation assembly includes air bleeding valve 5 and the exhaust joint 6 being communicated at air bleeding valve valve pocket, is vented the motion energy of valve core
Enough adjust the aperture of exhaust joint, flow velocity during in order to control exhaust.
In order to improve chemical stability, cleannes are improved, it is stainless steel that the material of each parts, which is selected,.
The present embodiment is first shut off gas deflation assembly in sampling, opens intake valve, SF6Gas is entered by inlet suction port
In sampling bottle, pressure gauge reaction bulb can be passed through by the aperture of air inlet valve regulation inlet suction port to adjust flow velocity during this
Interior gas flow, air intake assembly is closed after completing sampling；Carry out opening air bleeding valve during micro- water gaging, by SF6Gas is connect by exhaust
, can be by the aperture for the motor adjustment exhaust joint for being vented valve core, with the row of regulation during this in head output to measuring instrument
Gas velocity degree, and experiment SF can accurately be controlled by the change of the pressure gauge monitoring pressure in the bottle6The amount of gas.
Sampling bottle can be designed and sized to volume 1L stainless steel gas sample bottle during experiment and used from sealing-in
Mouth, enclosed valve, and it is 0-1Mpa that the range of pressure gauge, which is selected,.Sampling bottle is fabricated to " grass-character-head " structure with interface, valve,
