Description
Technical field
The utility model relates to a kind of oil sample sampler, especially relates to a kind of 1000kV oil-filled equipment insulating oil sampler.
Background technology
Along with the construction of China's hundred ten thousand volts extra-high voltage grids, increasing large oil immersed formula transformer and shunt reactor will drop into be installed and uses.And the stand the test standard of 1000kV insulating oil is high compared with other electric pressures, granule content standard in oil (granularity≤1000/100mL of 5 μ m～100 μ m, without 100 μ m above 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 will directly affect the accuracy of test findings.The ground that if sampling environment is mud ground etc. accumulates more dust earth, when air is dry and during with wind or Vehicle Driving Cycle, big and small dust will float in air, and after heavy rain, moisture in air humidity is larger, when light rain or snowfall, if not protection, raindrop, the snowflake etc. that contains impurity will be sneaked into oil sample, affects 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 dustproof room of mobile sampling, it mainly adopts dividing plate and plastic sheeting to be combined into an interim barrier that can hold staff and carry out oil sampling.Because its volume is larger, testing crew sampling operation space is well-to-do, convenient working, but be inconvenient to move, heavier.Adopt the dustproof room of mobile sampling to determine to arrange people's import and export, and it is mainly spliced by plastic sheeting and dividing plate, therefore it is difficult to accomplish totally-enclosed, and dust, moisture still can enter.
Two, the simple and easy sampling system being used in conjunction with by plastics or metal drum, plastic sheeting and plastic flexible pipe is that current extra-high-speed 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, when sampling, remove partly plastic film, 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 in the time of sampling, hand must enter in bucket and operate simultaneously, space is little causes action inconvenience, and now dust-proof effect also can decline.In the time that ground is uneven, also need someone to hold up bucket, increase artificial.Sampling personnel's sight line 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. the mobile inconvenience of device;
3. sampling operation inconvenience;
4. while sampling, the visual field is unintelligible;
5. only prevent the measure that outside contamination enters, there is no really to control the measure of internal contamination.
