Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated:
The utility model is divided into: gas bottle 1, mark vacuum extractor of gas cylinders 13; Calibrating gas injection module 14; Fill nitrogen compression module 15; Quantitative test module 16.
Mark vacuum extractor of gas cylinders 13, comprises vacuum pump 4, pneumatic tube 3, and switching nut 2, described vacuum pump 4 is connected with gas bottle 1 by pneumatic tube 3 in use, between described pneumatic tube 3 and gas bottle 1, by the nut 2 of transferring, is connected; The fundamental purpose vacuumizing is that the air of mark gas cylinder internal is found time as much as possible, and making in gas bottle is negative pressure, so that calibrating gas injects, each gas bottle pumpdown time is 10 minutes.
Calibrating gas injection module 14, comprises the syringe 8 of 10mL, the syringe 8 of 100mL, pure methane source of the gas, pure ethane source of the gas, pure ethylene source of the gas, pure acetylene source of the gas, pure hydrogen source of the gas, pure carbon monoxide source of the gas, seven kinds of calibrating gas of pure carbon dioxide source of the gas.By sealing rubber pad 5 for 1 mouthful, gas bottle, capstan nut 6 is twisted, and utilizes syringe 8 to get in the cavity of pure gas insertion sealing gasket and nut formation from gas source of the gas, opens the switch valve of gas cylinder, because gas cylinder is through vacuumizing, negative pressure can suck the pure gas in syringe in gas bottle.Wherein the injection rate IR of pure methane, pure ethane, pure ethylene, carbon monoxide is 10mL, and the injection rate IR of pure acetylene is 5mL, and the injection rate IR of pure hydrogen is 20mL, and the injection rate IR of pure carbon dioxide is 100mL.General injection rate IR number according to the roughly content of each component of operating transformer oil dissolved gas, determine, but show that without document gas concentration can exert an influence to experimental result.In this module, due to the method for implanting of the bubble-tight problems such as sealing gasket and syringe, the infiltration of air is unavoidable.
Fill nitrogen compression module 15.By the gas bottle 1 of crossing through one, two resume module, being connected into pressure is the High Purity Nitrogen gas cylinder 10 of 100MPa, open switch valve, carry out pressurized treatments, the partial pressure of controlling reduction valve is 1.0MPa, after meter pointer is stable, gas bottle is tightened to switch valve, put into gas cabinet and preserve a week, allow various components fully mix.In this process, the effect of tight mouthpart (12) is to connect the pneumatic tube 3 stator interfaces of second depressurized valve 11, prevents that air pressure is excessive and causes punching press failure.
Quantitative test module 16.Gas bottle by after mixing, connects reduction valve, to chromatograph sample introduction, carries out quantitatively.
Quantivative approach adopts chromatogram external standard method, and the higher calibrating gas of degree of accuracy of the concentration known that in the time of quantitatively, chromatograph adopts writes on the concentration of each component on label and is attached on gas bottle after quantitatively.
In quantitative module, only to the methane in institute's preparing calibrating gas, ethane, ethene, acetylene, hydrogen, carbon monoxide, carbon dioxide carries out quantitatively, and because the air that step 1, two, three is brought into, carbon dioxide is wherein by quantitatively, and oxygen and nitrogen etc. is not required component, on not at all impact of testing result.
