Abstract

The utility model relates to a device for sampling and analyzing gas materials, and particularly belongs to a gas analyzer. The gas analyzer adopts the technical scheme that the gas analyzer is formed by connecting a gas inlet sealing connector with a pressure cushioning device through a conducting pipe, connecting the pressure cushioning device with a flow capacity adjusting module, connecting the flow capacity adjusting module with a magnetic valve, connecting the magnetic valve with a gas measuring device with a gas sensor inside, and connecting the gas measuring device is connected with a gas guiding device. The gas analyzer has the beneficial effects that since the gas analyzer adopts the gas measuring device of the gas sensor, the device has the function of automatic judgment, and can be switched to the most suitable measuring range in different gas content ranges, thereby the trace contents of SO2, H2S and CO with SF6 and N2 as base gas can be measured, and the maximum accuracy can reach 0.1ul/L.

Description

Gas analyzer

Technical field

The utility model relates to a kind of to the gas material sampling analysis device, especially belongs to a kind of gas analyzer.

Background technology

The test of SF6 decomposing gas thing is to using SF6 to have very important significance as the electrical equipment tool of insulating medium in the transformer station.By detecting the decomposition product of SF6, can analyze phenomenons such as whether the electric arc flashover took place in this air chamber, and then judge whether to shut down this electrical equipment operation such as maintenance.At present domestic more existing be used to detect the checkout equipment of SF6, yet have all mostly that test is unstable, optional range is single, gas test device problems such as damage easily.

Summary of the invention

The purpose of this utility model is to provide a kind of high Precision Detection device, makes that the micro-content composition in the gas is detected.

Technical solution adopted in the utility model is: it is to be linked to each other with pressure buffer device by conduit by the air inlet sealing adaptor, pressure buffer device links to each other with the flow regulation module, the flow regulation module links to each other with solenoid valve, solenoid valve links to each other with the gas measurement device that gas sensor is equipped with in inside, gas measurement device link to each other with means for guiding gas form.

The beneficial effects of the utility model are: 1, the utility model is owing to adopted the gas measurement device of gas sensor, and this device has automatic judgement, and can be in the scope of gas with various content, switch to only range, therefore can detect with SF6, N2 is SO2, H2S under the spirit and the micro-content of CO, and accuracy of detection reaches as high as 0.1ul/L; 2, the inner multi-layer gas control device that adopts of the utility model provides stable physical condition, has guaranteed the stability of test; Be provided with large and small two grades of ranges, switching ranges as required; Instrument internal chosen gas circuit, the air chamber made from the Teflon macromolecular material, reduced effectively gas circuit, air chamber wearing and tearing, prolonged instrument serviceable life.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Be illustrated in figure 1 as the utility model schematic diagram, it is to be linked to each other with pressure buffer device 3 by conduit 2 by air inlet sealing adaptor 1 as can be known from diagram, pressure buffer device 3 links to each other with flow regulation module 4, flow regulation module 4 links to each other with solenoid valve 5, solenoid valve 5 links to each other with the gas measurement device 7 that gas sensor 6 is equipped with in inside, gas measurement device 7 link to each other with means for guiding gas 8 form.

The quantity of the gas measurement device 7 described in the utility model is 2 groups, and 3 gas sensors 6 are equipped with in every group of inside, and this gas sensor 6 is respectively applied for the content of measuring SO2, H2S and CO gas.

Conduit 2 described in the utility model is made by the Teflon macromolecular material.

Set forth its course of work below in conjunction with Fig. 1 specific embodiment of the utility model:

Gas to be measured by air inlet sealing adaptor 1, is entered pressure buffer device 3 by conduit 2, and in this link, pressure buffer device 3 carries out step-down with gas to be measured, and it is tentatively adjusted to a threshold values that is fit to measurement.Then, gas to be measured will be by flow regulation module 4, by this module people the flow of gas to be measured is converted to the digital quantity that can show by analog quantity on display screen, and by this digital quantity, gas to be measured is regulated again, gas to be measured is adjusted to threshold values of suitable measurement, to guarantee the accuracy of test.

Gas to be measured will begin to carry out formal measurement after handling through above-mentioned steps.

Gas to be measured after treatment will enter solenoid valve 5 from flow regulation module 4, enter the gas measurement device 7 of two groups of different measuring precision by solenoid valve 5, why taking two groups of gas measurement devices 7, is in order to guarantee better in the threshold values interval, measuring accuracy accurately.Two groups of gas measurement device 7 inside, contain 3 gas sensors 6 respectively, they are converted to faint electric weight with the micro-content of the SO2 in the gas to be measured, H2S and CO, are converted to the measured value of our precision as can be known again by high-precision circuit.After measuring end,, the gas unidirectionals remaining to be measured in two gasmetry mechanisms 7 are discharged outwardly, accomplish that tail gas does not interfere with each other, can guarantee the measuring accuracy of gas so again by means for guiding gas 8.
