Description
Technical field
This utility model belongs to the preparing technical field of micro- water oil sample, and in particular to a kind of micro- water oil of simple low concentration standard
The preparation facilitiess of sample.
Background technology
With the continuous propulsion of strong intelligent grid, expansion and the voltage apparatus grade increasingly of the structure of power industry are not
Disconnected to improve, the maintenance of transformator is more and more important, and during the operation maintenance of transformator, the micro-water content in transformer oil is
One important index, micro-water content plays decisive influence to the insulating properties of oil in oil, and excessive water content will accelerate in oil
Aging, the reduction insulating properties of insulant, increases dielectric loss.When micro-water content exceedes certain value, the insulating properties of equipment will
Substantially reduce, insulation breakdown, burning apparatus can be caused when serious.The micro-water content in oil is also done in actual power generation
Strict regulation with require.Therefore, the micro- water of transformer oil is controlled before transformator puts into operation could be more favourable in below 10mg/L
In the stable operation of transformator, the micro-water content of the transformer oil for normally running in 25mg/L or so, in practical operation
Cheng Zhong, many laboratory technicians have found that the micro- water oil sample of standard of below 10mg/L concentration is difficult to prepare, and wayward.How this is configured
The micro- water oil sample of standard of low concentration is planted into a technological difficulties, the invention provides a kind of system of the micro- water oil sample of transformator standard
Standby device, especially for the micro- water oil sample of standard of low concentration, realizes inexpensively and easily.

After data, data acquisition is finished by data acquisition unit, directly intuitively shown by data display screen, so just
The content of the micro- water of oil sample can at any time be detected.
(6) preparation of humble water concentration oil sample.Because oil sample is placed in closed glass desicator, in being dissolved in oil
The content of water, can be longer and gradually reduce with the time placed, and being finally reached the numerical value of perfect condition, to be 0mg/L. same
When due to the probe of micro- water sensor be placed on prepare blank oil in, the micro-water content of oil sample to be measured is capable of detecting when at any time,
When the micro-water content data display for detecting is less than 10mg/L, oil sample required for us, the oil sample for having filtered just have been prepared
General placement just can reach requirement of experiment in 2 days or so, if the amount that desiccant is placed in glass desicator is more, reach experiment
The standing time of requirement can be shorter.
The beneficial effect of the utility model is：The device for formulating is simple to operate, test data precisely, experimental facilitiess and material
Material is cheap, is capable of monitor in real time and prepares the micro-water content of standard oil sample, and is easily achieved and reaches requirement of experiment, while low concentration
Micro- water oil sample also can be long time stored in exsiccator.
