Abstract
The utility model relates to a quantitative sampler, which comprises a sampling needle cylinder, a fixing sleeve, a positioning guide post and a connecting rod, wherein the fixing sleeve is arranged on the outer wall of the sampling needle cylinder; and one end of the positioning guide post is arranged in a piston of the sampling needle cylinder, and the other end is connected with the fixing sleeve through the connecting rod. Aiming at different sampling doses, the relative position of the connecting rod and the fixing sleeve can be adjusted. Compared with the prior art, the quantitative sampler has the beneficial effects that a series of tests show that the extraction result in each time is in the error range for the same dose of test oil, and the sampling accuracy and the working efficiency of the chromatography analysis test of gas in transformer oil are obviously increased.
Description
Technical field
The utility model relates to the gas analysis field of transformer oil, relates in particular to a kind of proportional sampling device.
Background technology
The gas that contains in the transformer oil is analyzed, be to determine whether transformer inside exists the most effectual way of latency fault, in this test, accurately the sample of amount extracts has considerable influence to the test findings accuracy, when extracting 1ml sample gas, the accuracy of sampling and speed have than big-difference because of test operation person's sampling gimmick is different.
Summary of the invention
The purpose of this utility model provides a kind of proportional sampling device, extracts low dose of sample gas fast, improves the precision and the work efficiency of Gas in Oil of Transformer stratographic analysis test.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of proportional sampling device is characterized in that, comprises sampling syringe, fixed cover, positioning guide column, connecting rod, and fixed cover is arranged on the sampling probe drum outer wall, and positioning guide column one end places in the sampling cylinder piston, and the other end is connected with fixed cover by connecting rod.
Adjustable at difference sampling described connecting rod of dosage and fixed cover relative position.
Compared with prior art, the beneficial effects of the utility model are: prove through test of many times, to same dosage formation testing, extract the result all in error range at every turn, significantly improved the sampling precision and the work efficiency of Gas in Oil of Transformer stratographic analysis test.
Description of drawings
Fig. 1 is the utility model example structure synoptic diagram.
Among the figure: 1-sampling syringe 2-fixed cover 3-positioning guide column 4-connecting rod 5-piston
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
See Fig. 1, it is a kind of proportional sampling device example structure of the utility model synoptic diagram, comprise sampling syringe 1, fixed cover 2, positioning guide column 3, connecting rod 4, fixed cover 2 is arranged on sampling syringe 1 outer wall, positioning guide column 3 one ends place in the sampling cylinder piston 5, and the other end is connected with fixed cover 2 by connecting rod 4.Adjustable at difference sampling dosage connecting rod 4 with fixed cover 2 relative positions.When needing sampling 1ml in the test, only need connecting rod 4 and fixed cover 2 correspondence positions are fixed getting final product, during use, as long as the upper end of piston 5 touching positioning guide column 3, the extraction amount is promptly qualified, and is easy to operate, accurate measurement can shorten test period more than 20 minutes at every turn, and work efficiency improves greatly.
