Description
Technical field
The utility model is mainly concerned with the checkout equipment field of sulfur hexafluoride gas, refers in particular to a kind of portable sulfur hexafluoride gas chromatograph, is used to detect steel cylinder SF
6SF in new gas and the on-the-spot operational outfit
6The purity of gas, air, carbon tetrafluoride and subfluoride component concentration.
Background technology
Sulfur hexafluoride gas (SF
6) be a kind of insulation arc-extinguishing medium of extremely superior high voltage electric equipment, its range of application and future are very wide.But the SF in equipment
6Gas purity reduction or oxygen, when carbon tetrafluoride content increases, can cause the obvious decline of its electric property.Therefore, guide rule is to gas purity, air, CF in the SF6 electrical equipment
4Content makes explicit provisions, particularly CF
4As the decomposition product of apparatus insulated material, but detect the latency fault of its content judgment device.At present, each run unit is more and more paid attention to SF
6The scene of electrical equipment is detected, for gas humidity, stop leakage in the roof and realized on-the-spot detection, but the detection of purity and decomposition product is still the method that adopts the testing laboratory of taking a sample back to analyze, there is fatal shortcoming and defect in this method: sampling error can't be eliminated, and the air of bringing into when particularly taking a sample directly influences each and analyzes data; That works is loaded down with trivial details, carry a large amount of sampling jars, also needs connecting tube at the scene, vacuumizes, extremely inconvenient; Expend a large amount of manpower and financial resources etc.
The utility model content
Problem to be solved in the utility model just is: at the technical matters that prior art exists, the utility model provide a kind of simple and compact for structure, volume is light and handy, with low cost, easy and simple to handle, be easy to carry, portable sulfur hexafluoride gas chromatograph stable and reliable for performance.
For solving the problems of the technologies described above, the solution that the utility model proposes is: a kind of portable sulfur hexafluoride gas chromatograph, it is characterized in that: it comprises carrier gas source, six-way valve, quantity tube, chromatographic column, thermal conductivity detector (TCD), chromatographic work station and display unit, the A mouth of described six-way valve is in communication with the outside, the B mouth links to each other with the two ends of quantity tube respectively with the E mouth, the D mouth links to each other with carrier gas source, the C mouth links to each other with thermal conductivity detector (TCD) by chromatographic column, the F mouth links to each other with gas to be measured, the output terminal of thermal conductivity detector (TCD) links to each other with chromatographic work station, and chromatographic work station will obtain data delivery and give display unit.
Described display unit is a portable computer.
Compared with prior art, advantage of the present utility model just is: portable sulfur hexafluoride gas chromatograph of the present utility model, have simple and compact for structure, volume is light and handy, with low cost, easy and simple to handle, be easy to carry, advantage such as stable and reliable for performance.Therefore general gas chromatograph generally is equipped with a plurality of detecting devices owing to need to detect various gaseous substances, causes its complex structure, in addition because the requirement of temperature programme must the internal furnace incubator, makes bulkyly, can only be adapted to the laboratory and use.And, only thermal conductivity detector (TCD) need be installed in instrument for the detection of sulfur hexafluoride gas, do not need temperature programme, to heating that chromatographic column only need be fixed.Therefore, volume of the present utility model has only 1/4th of universal gas chromatograph, and weight has only 1/8th of universal gas chromatograph, is easy to carry, and can satisfy the on-the-spot needs that detect.And this instrument performance is stable, and is easy to operate, and the general gas chromatograph in its technical parameter and laboratory is consistent, can satisfy the requirement of sulfur hexafluoride detection.
