Description
Technical field
The present invention relates to a kind of aid when adopting the dielectric oil chromatographic analysis method, be specifically related to a kind of instrument for gas sampling when the stratographic analysis.
Background technology
The dielectric oil chromatographic analysis method is a kind of diagnostic techniques of oil-filled equipment being carried out state estimation.It provides effective insulation control to electrical equipment, guarantees the safe and stable operation of electrical equipment.Specifically use the component concentration of gas chromatography determination Dissolved Gases in Insulating Oil, measurement result judges for power supply enterprise whether operating oil-filled power equipment exists the faults such as overheated, the discharge of latency, to ensure that power grid security effectively moves, this also is oil-filled electric equipment manufacturing firm carries out factory inspection to its equipment necessary means.GB/T7252-2001 to the requirement of stratographic analysis test figure is: to the analysis result of the repeatedly sample introduction of same gas sample, should mean value ± 1.5% in.
Its structure of injector that uses at present is common 1ml medical glass syringe.As requested, air inflow should remain on 0.5ml when carrying out chromatography test.Can only rely on the individual of testing crew to operate when getting gas for old injector, sample size is wayward, error can occur unavoidably, affects the accuracy of test figure.Through concentrating the sample introduction process of injector is analyzed, find to cause the main cause of poor repeatability just: gas production and air inlet can't accurate quantifications.And, in injector inserting needle process, because there is certain pressure in chromatographic injection port, approximately about 0.2Mpa, be easy to the injector core is ejected, cause the test operation failure, as requested accurate quantification.
The syringe needle pinprick of injector use is smaller in addition, because the sample introduction pad of injection port is silica gel material, syringe needle often contacts the sample introduction pad when sample introduction, so just is easy to stop up, and causes and can't normally use, and needs often to change syringe needle, affects the efficient of work.
Summary of the invention
In order to solve the problems such as existing, the invention provides a kind of gas production, air inlet accurate quantitative analysis, syringe needle stops up the oil chromatography analytical standard injector that also can work.
For addressing the above problem, the present invention by the following technical solutions:
A kind of oil chromatography analytical standard injector, formed by syringe cylinder, injector push-rod, syringe needle and fixed support, fixed support two screw rods and the hold-down nut that comprise fixed head, control panel, upper strata baffle plate and connect above-mentioned three plates wherein, fixed head is fixed on the syringe cylinder, the top of injector push-rod is provided with the upper strata baffle plate, the upper strata baffle plate is connected two screw rods and connects with fixed head, be provided with upper strata baffle plate nut on baffle plate top, upper strata; Also be provided with control panel between upper strata baffle plate and fixed head, control panel passes above-mentioned screw rod, and adjusts position and location by the control panel nut that is arranged on the control panel bottom.
Further, described fixed head, control panel and upper strata baffle plate are transparent organic glass material, and a side of described upper strata baffle plate is provided with arc groove.
In addition, described syringe needle is provided with by-pass port.
The good effect that the present invention has is, first guaranteed gas production, air inflow accurately, second has guaranteed that injector push-rod can not be pushed out because of admission pressure, the 3rd, even the by-pass port by syringe needle has realized that syringe needle stops up and also can continue test.

Embodiment
The present invention is described in detail below in conjunction with accompanying drawing 1-3.
With reference to Fig. 1, oil chromatography analytical standard injector of the present invention is by syringe cylinder 1, injector push-rod 2, syringe needle 3 and fixed support form, wherein fixed support comprises fixed head 4, control panel 5, upper strata baffle plate 6 and the screw rod and the hold-down nut that connect above-mentioned three plates, fixed head is fixed on the syringe cylinder 1, the top of injector push-rod 2 is provided with upper strata baffle plate 6, because chromatographic injection port has certain pressure, upper strata baffle plate 6 has guaranteed that injector push-rod 2 is unlikely to eject under the effect of pressed gas, avoided the risk of operation failure, upper strata baffle plate 6 is connected with fixed head and is connected by two screw rods 7, on upper strata baffle plate 6 tops upper strata baffle plate nut is set and is fixed.
Also be provided with control panel 5 between this external upper strata baffle plate 6 and the fixed head 4, control panel 5 also passes above-mentioned screw rod 7, and adjust position and location by the control panel nut 9 that is arranged on control panel 5 bottoms, by adjusting the position of control panel 5, can make the gas production of injector reach accurately requirement.Through repeatedly test, the result shows that each gas production and air inflow all reach standard-required.Above-mentioned fixed head 4, control panel 5 and upper strata baffle plate 6 are transparent organic glass material, can carry out easily all processes of observation experiment.
With reference to Fig. 2, in order to make things convenient for the manual operation of injector push-rod 2, a side of upper strata baffle plate 6 arranges an arc groove, and the experimenter carries out manual operation by this groove, realizes easily the function of gas production and air inlet.
Fig. 3 is the detail view of syringe needle 3, the pinprick of the syringe needle 3 that injector uses is smaller, and chromatographic sample introduction pad is silica gel material, stop up because of the contact silicagel pad easily during intake operation, therefore, open in addition a by-pass port 10 by the file head on the next door of syringe needle, by-pass port 10 does not contact with silica gel is positive like this, even pinprick stops up, air inflow can not change yet, and has guaranteed the accuracy of stratographic analysis test figure.
Although above-mentionedly by reference to the accompanying drawings the specific embodiment of the present invention is described; but be not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection scope of the present invention.
