Description
Technical field
The present invention relates to a kind of oil sample sampler, especially relate to a kind of 1000kV oil-filled equipment insulating oil sampler.
Background technology
Along with the construction of China hundred ten thousand volts extra-high voltage grid, input is installed and is used by increasing Large Oil immersion transformer and shunt reactor.And the stand the test standard of 1000kV insulating oil is high compared with other electric pressures, in oil, granule content standard (granularity≤1000/100mL of 5 μm ~ 100 μm, without more than 100m particle) is exclusive in 1000kV oil test project especially.Accomplish that the last test findings of 1000kV insulating oil is up to standard, except oil strain machinery and oil strain method, the sampling method of insulating oil is also a vital ring, and it directly will affect the accuracy of test findings.If sampling environment is the ground that mud ground etc. accumulates more dust earth, during when air oxygen detrition and with wind or vehicle traveling, big and small dust will float in air, and after heavy rain, moisture in air humidity is comparatively large, when light rain or snowfall, if not protection, raindrop containing impurity, snowflake etc. will be mixed into oil sample, affect test findings.So need develop a kind of device that can carry out accurate sampling operation, and sampling process does not affect the test findings of insulating oil.
Sampling method in existing 1000kV oil test project mainly contains:
One, the dust-proof room of mobile sampling, it mainly adopts dividing plate and plastic sheeting to be combined into one can hold the temporary barrier that staff carries out oil sampling.Because its volume is comparatively large, testing crew sampling operation space is well-to-do, convenient working, but be inconvenient to move, heavier.Adopt the dust-proof room of mobile sampling then to determine the import and export that will arrange people, and it is spliced primarily of plastic sheeting and dividing plate, therefore it is difficult to accomplish totally-enclosed, and dust, moisture still can enter.
Two, by plastics or metal drum, plastic sheeting and plastic flexible pipe with the use of simple and easy sampling system be that current extra-high force feed samples conventional method.It mainly adopts the semienclosed container such as Plastic Drum or metal bucket compound rubber circle and plastic sheeting to make dust guard, and plastic flexible pipe is connected on sample tap, remove partly plastic film during sampling, open fuel outlet valve, make insulating oil flow into sampling jar through plastic flexible pipe.The method preliminary work is convenient, and dust-proof effect is also better.But when sampling, hand must enter in bucket and operate simultaneously, space is little causes action inconvenience, and now dust-proof effect also can decline.When ground is uneven, also needs people and hold up bucket, increase artificial.The sight line of sampling personnel is blocked in the wrinkling meeting of plastic sheeting, is unfavorable for sampling.
In general, all there are some defects in above two methods:
1. with extraneous not isolated;
2. device moves inconvenience;
3. sampling operation inconvenience;
4. during sampling, the visual field is unintelligible;
5. the measure only preventing outside contamination from entering, does not really control the measure of internal contamination.
