Description
Technical field
The utility model relates to a kind of glass syringe for insulating oil gas chromatographic analysis sealing sampling auxiliary joint device, belong to electric power transformer insulated oil gas chromatographic technical field.
Background technology
Due to all many-sided reasons of the equipment de-sign such as large-scale power transformer, current transformer, manufacture, quality and operation, serious accident and the fault of these equipment happen occasionally, and have a strong impact on the safe and stable operation of electrical network.For guaranteeing the safe operation of the equipment such as transformer and even electrical network, the many different monitoring method of development, wherein with the content utilizing vapor-phase chromatography to detect various dissolved gas in insulating oil, with this judge the type of oil-filled electric equipment internal fault and the order of severity the most effective.
Vapor-phase chromatography, it is the chromatographic technique that a kind of compound not occurring to decompose to being easy to volatilize in organic chemistry carries out separation and analysis, its utilize all components that will be separated mobile phase alternate with Stationary liquid two be assigned difference, be separated and calculate gas composition content, judging oil-filled equipment internal fault.In analysis, frequent use glass syringe sealing sample connection, but between glass syringe during gas transfer, due to sampling sealing adaptor surface and rubber Capsule smooth and firmly, syringe needle skids in joint and inserts not enter glass syringe or insert partially, cause sample unsuccessfully, sample is contaminated, the domestic artificial experience that only relies on solves at present.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and provide a kind of structure simple, easy to use and reliable, the work efficiency of oil dissolved gas stratographic analysis can be improved, solve the sealing of the glass syringe for the insulating oil gas chromatographic analysis sampling auxiliary joint device of the smooth branch problem of gas between syringe.
The purpose of this utility model has been come by following technical solution, a kind of sealing of the glass syringe for insulating oil gas chromatographic analysis sampling auxiliary joint device, described glass syringe sealing samples to comprise in one and detects the A glass syringe and of gas with the B glass syringe sampling syringe needle containing sampling, described A glass syringe is configured with one can insert from A glass syringe head and be plugged in the sampling auxiliary joint A glass syringe, the side end of this sampling auxiliary joint is provided with a funnel shaped syringe needle guide, and this funnel shaped syringe needle guide and A glass syringe head rubber sealing cap can achieve a butt joint and clamp after grafting is located.
Sampling auxiliary joint described in the utility model comprises and to contact with A glass syringe and to realize fixation adapter bracket, and described adapter bracket both sides have the window observing sight line when not affecting sampling.
The utility model is the defect overcoming prior art, improves the work efficiency of oil dissolved gas stratographic analysis, and special glass syringe of doing seals sampling auxiliary joint device, and specialized designs syringe needle penetrates a little, will stop syringe needle and skids or insert inclined phenomenon.Sampling auxiliary joint critical piece is infundibulate guide, i.e. syringe needle guide, makes it concentric with the rubber sealing cap (plug) of glass syringe, and is fixed on glass syringe front end by resin joint support, during guarantee gas transfer, syringe needle vertically inserts syringe, does not touch syringe inwall.
In gas chromatographic analysis, sealing sampling the completing of auxiliary joint, stops syringe needle in oil chromatogram analysis and skids or insert inclined phenomenon, and do not occur because the problems such as sampling failure that local derviation causes, sample be contaminated pricked by syringe needle, secure sample shifts; By glass syringe sealing sampling auxiliary joint in development gas chromatographic analysis, improve the work efficiency of oil dissolved gas stratographic analysis; Raising test accuracy of measurement, the safe and reliable operation for electrical network provides truly, effective data; Meanwhile, the development of this equipment reduces the loss of sampling syringe needle, Capsule, for enterprise saves equipment cost.
It is simple that the utility model has structure, easy to use and reliable, can improve the work efficiency of oil dissolved gas stratographic analysis, to solve between syringe the features such as the smooth branch problem of gas.
Accompanying drawing explanation
Fig. 1 is use structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1, a kind of sealing of the glass syringe for insulating oil gas chromatographic analysis sampling auxiliary joint device described in the utility model, described glass syringe sealing sampling comprises in one and detects the A glass syringe 1 and of gas with the B glass syringe 3 of sampling syringe needle 2 containing sampling, described A glass syringe 1 is configured with one can insert from A glass syringe head and be plugged in the sampling auxiliary joint 4 A glass syringe 1, the outboard end of this sampling auxiliary joint 4 is provided with a funnel shaped syringe needle guide 5, and this funnel shaped syringe needle guide 5 can achieve a butt joint with A glass syringe 1 head rubber sealing cap 6 and clamp after grafting is located.
Shown in figure, described sampling auxiliary joint 4 also comprises and to contact with A glass syringe 1 and to realize fixation adapter bracket 7, and described adapter bracket both sides have the window observing sight line when not affecting sampling.
embodiment:the A glass syringe 1 of 100ml inserts sampling auxiliary joint 4, rotates A glass syringe 1, makes injector head rubber sealing cap 6 and auxiliary joint 4 block jail, causes infundibulate syringe needle guide 5 and rubber sealing cap 6, A glass syringe head on same perpendicular line.Then use double end syringe needle 2, insert from guide 5, the sampling in A glass syringe 1 is detected gas (balanced gas) and transfers in the B glass syringe of 5ml, use in order to stratographic analysis.
