In GB/T 7252-2001,6.1 perform.
2.1.1 sampling method and position
The overall process drawn oil sample from equipment should be carried out under whole sealing status, and oil sample must not be with air contact.Sampling point should
Notice that taken oil sample can represent the gassiness situation of apparatus body oil, typically should draw oil sample at the bottom sample cock of equipment.
Under special circumstances, can be in different sampling point samplings.The sample cock of equipment should mix the adapter of band oil smallmouth, little
Flexible pipe is connect on mouth.The air in transformator pipeline, sampling line and in sample cock and " dead oil ", glue used should be got rid of before sampling
Pipe should be the shortest, simultaneously with the oil flushing pipeline of apparatus body.When drawing oil sample, oil stream should be mild.
2.1.2 sampling instrument
Use standard 100 ml injector for medical purpose, seals sampling with three-way valve.Require before sampling first to check needle tubing sealing, then use
Moistening needle tubing is rinsed in formation testing, to ensure that syringe is lubricious and seals.In whole operating process, it is to avoid needle tubing occurs bubble.When
When syringe is filled with oil sample, fuse by oil volume variation with temperature slidably can make internal and external pressure balance.
2.1.3 sampling amount
Use standard 100 ml injector for medical purpose, sampling amount is at 50～80 ml.
2.2 degassing
What Gases Dissolved in Transformer Oil on-Line Monitor Device degassing mode was commonly used is dissolution equilibrium method mechanical oscillation method.
Mixed gas, after constant temperature oscillation is deviate from oil, should be transferred in glass syringe as early as possible, to avoid gas and to take off
When the oil of gas contacts, change its composition because of each component back dissolving selectively.The gas sample deviate from should be carried out chromatograph as early as possible divide
Analysis, it is to avoid store for a long time and cause gas escape.
2.3 gas analysis
Online gc on-the-spot testing test be to 8 components of oil dissolved gas (hydrogen, carbon monoxide, carbon dioxide, methane,
Ethane, ethylene, acetylene, total hydrocarbon) content analysis and comparison.On-the-spot on-line gas chromatography should be able to meet power industry standard
The requirement of 8.2 pairs of gas chromatograpies in DL/T 722-2000 or standard GB/T/T 7252-2001.
2.4 sample introduction
Use 1 ml syringe sampling, the syringe that air-tightness is good and calibrated should be selected, to ensure good sampling volume
Accuracy.Sample analysis and instrumental calibration must use same syringe, and sampling volume is identical, all takes 0.5 ml, to reduce by mistake
Difference.
2.5 verification data
The analytical data utilizing on-the-spot on-Line Monitor Device analyzes on-the-spot transformer body oil and calibrating dress with portable chromatograph
The data putting oil sample are compared, and record the data of on-Line Monitor Device and the measurement data of portable chromatograph, according to two
The data of person calculate measurement error and the repeatability of online gc.
3 online gc check results
