Description
Technical field
This utility model is related to a kind of accurate sampler of sulfur hexafluoride gas detection, belongs to High-Voltage Electrical Appliances Site Detection skill
Art field.
Background technology
By moisture, catabolite, purity detecting, monitoring device are carried out to the electrical equipment filling sulfur hexafluoride gas
Operation conditions has been a kind of generally acknowledged discovery electrical equipment malfunction, the effective means ensureing equipment safety operation.At present, electric power row
Industry requires 110kV and the above electrical equipment filling sulfur hexafluoride to take within 3 years a sample to be detected, after every sub-sampling has connect instrument
The immobilising gas of gas seam will be taken to drain only, and the gas pressure after instrument and flow will be all very little, this will be just
Need to spend longer time, if gas of not checkmating drains only, can be very big on testing result impact, or even mislead production O&M people
Member, leads to equipment to have an accident, and affects power grid security.
In recent years, sulfur hexafluoride moisture on-line monitoring technique detects as equipment outage analysis supplement and development,
Because it has the advantages that continuous on-line monitoring, its application is for the timely fault finding electrical equipment, it is to avoid the generation of accident.
Live on-Line Monitor Device is typically mounted on monitored equipment, takes gas interface to be connected with equipment, this also results in online water
Divide full of the sulfur hexafluoride that do not flow with pressure such as equipment in the sensor cell of instrument, when electrical equipment will be taken with edema caused by disorder of QI analysis, this
The gas that part retains will enter analytical tool, and then affects testing result.
The sampler of most of sulfur hexafluoride gas detection currently on the market, is all not equipped with exhaust apparatus, when need
Take cumbersome during gas operation, waste time and energy, and testing result can be affected.
Content of the invention
The purpose of this utility model is, for the existing gas analyses time filling sulfur hexafluoride equipment longer, take gas joint
And online Moisture Meter be contained within not flowing dead gas can be on the shortcoming of testing result impact, the utility model proposes a kind of sulfur hexafluoride
The accurate sampler of gas detecting.
Realizing the technical solution of the utility model is, this device, before sulfur hexafluoride gas analysis, is reclaimed using gas
Device air inlet air relief valve will take the gas retaining always in gas interface, online Moisture Meter rapidly to enter retracting device it is ensured that six
Sulfur fluoride moisture, catabolite, the accurate quantitative analysis detection of purity.
A kind of accurate sampler of sulfur hexafluoride gas of this utility model detection include filling sulfur hexafluoride electrical equipment,
Threeway sampling valve, analytical tool injection valve, sulfur hexafluoride analytical tool, gas concentration unit air inlet air relief valve, pressure gauge, gas
Retracting device.The input port of threeway sampling valve connects the electrical equipment filling sulfur hexafluoride, the output port of threeway sampling valve its
In one termination analytical tool injection valve, analytical tool injection valve connect sulfur hexafluoride analytical tool;Gas sample is analyzed through sulfur hexafluoride
Gas concentration unit is entered back into after Instrumental Analysis;The other end of the output port of threeway sampling valve connects gas concentration unit air inlet
Air relief valve, and in recovery pipe, a pressure gauge is installed, before gas analyses, the gas in equipment quickly can be entered back
Receiving apparatus.
In the accurate sampler work being detected using sulfur hexafluoride gas, by fill sulfur hexafluoride gas chopper,
The gas interface that takes of the equipment such as transformer, transformator, GIS is docked with the three-way valve of this device, then by returning after three-way valve
Receiving apparatus air inlet air relief valve is slowly opened, when the pressure value of recovery pipe upward pressure table is 0.1MPa(Relative pressure)When, stop
Air relief valve operates, and is maintained at this pressure and the sulfur hexafluoride gas in electrical equipment was entered retracting device in 1 minute, turns off decompression
Valve.Open the injection valve of analytical tool, adjust gas flow, sulfur hexafluoride gas sample enters back into gas after instrument detection and reclaims
Device is reclaimed.After detection terminates, close the injection valve of analytical tool, the gas interface that takes of electrical equipment is divided with this device
From.
The beneficial effects of the utility model are that the accurate sampler of this utility model sulfur hexafluoride gas detection can be right
Fill the chopper of sulfur hexafluoride gas, transformer, transformator, GIS etc. and carry out quick and accurate sampling, particularly to equipped with online
The gas retaining always in online instrument rapidly can be entered retracting device it is ensured that hexafluoro by the sulfur hexafluoride equipment of Moisture Meter
Change the accurate quantitative analysis detection of sulfur moisture, catabolite, purity.Save substantial amounts of detection time, substantially increase detection
Accuracy and efficiency.
This utility model is applied to gas sample in the electrical equipment filling sulfur hexafluoride gas, analysis.
