Description
Technical field
The utility model relates to a kind of measurement and analysis SF that is used for electric power system
6The SF of the humidity of gas, purity and analyte
6Gas Quality Analyzer.Psychrometrc analysis comprises relative humidity RH, dew point Td, volume ratio PPM, purity analysis SF
6Content in air Air, the analyte analysis comprises analyte HF, H
2S and SO
2Analysis.
Background technology
Since the fifties in last century, SF
6Be widely used in the high voltage electric appliance with its good insulating property and superior arc quenching characteristic.But, SF
6In micro-moisture can cause the corrosion of high-voltage electrical equipment, and can cause the insulating capacity of high-voltage electrical equipment to descend.This is because electric equipment is in operation, and tends to produce electric arc, SF
6Ionization generates various impurity under the effect of electric arc, and these impurity and moisture generation hydrolysis reaction mainly generate HF and H
2SO
3, they have very strong corrosivity, will produce corrosive attack to the insulating material in the electric equipment, reduce its surperficial insulation resistance, influence its insulating property.Again, common SF
6In micro-moisture be that form with water vapor exists, when temperature descends, may form liquid water to the water-setting of gaseous state, on piece surface, thereby cause the insulating part surface to produce creeping discharge and cause accident.In addition, SF6 gas is being subjected to arcing and is having under the participation of moisture, can produce fluorine sulphur compound at a low price, wherein has the part sub-compound finally to become HF, H
2S and SO
2, they all belong to toxicity and the very strong material of corrosivity.So, by to HF, SO
2And H
2The analysis of these analytes of S just can further be understood SF
6Gas contains the degree of decomposition product, thereby understands SF in the High-Voltage Electrical Appliances
6The changing condition of gas provides the foundation of science for early diagnosis.
At present, measurement, analysis SF are also arranged on the domestic and international market
6Purity and the instrument of humidity.But no matter be online or portable, the function singleness of these instrument can only be measured one or a kind of parameter in purity or the humidity.In addition, to SF
6Original method is also adopted in the analysis of analyte, as the water-soluble back of analyte PH test paper method, and does not have the method for electronics.Moreover these instrument are not strong to the processing capacity of data, only have to preserve to wait some shirtsleeve operations, and the data of surveying can not form complete electronics shelves or paper document is done permanent preservation.The 4th, these instrument can not directly be carried out the man-machine communication, want to realize that the man-machine communication must be by computing machine or network system.The 5th, the Show Color dullness of these instrument, for black or grey.The 6th, the demonstration curve of these instrument is single, and synchronization can only show the curve of some parameters.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art existence and a kind of unitary sampling is provided, both energy measurement SF
6Purity, energy measurement SF again
6Humidity and can realize SF
6The portable measurement of analyte content analysis and analysis SF
6The gas analyzer of the humidity of gas, purity and analyte.
The purpose of this utility model is achieved in that gas inlet passes through pipeline contact successively variable valve, 3-way valve, humidity sensor, purity sensor, HF sensor, H
2S sensor and SO
2Sensor, electronic flow-meter, and be connected to exhausr port with a pipe; The 3rd valve of 3-way valve connects a drying;
Purity sensor, HF sensor, H
2S sensor and SO
2The signal wire of sensor is wired to the input end of multiway analog switch, and output terminal is wired to the input end of AD converter, and the output signal of AD converter is wired to microprocessor; The flow signal of electronic flow-meter is wired to microprocessor; The color touch screen is connected by multiple conducting wires with microprocessor; Microprocessor links to each other with level transferring chip MAX232 by lead, 2 serial ports have been expanded, wherein, serial ports links to each other by the signal end of lead and humidity sensor, another serial ports links to each other with mini-printer by lead, this serial ports can link to each other with the pc machine when printer is not worked, and realizes and the communicating by letter of PC.
Purity sensor, HF sensor, SO
2Sensor, H
2Position between the S sensor can exchange.
The utility model is once finished all parameter measurements for the sampling of measurement parameter single, and we have adopted high performance microprocessor, and sample rate that it is exceedingly fast and arithmetic speed can be finished all parameter measurements in a short period of time.Simultaneously we are designed into one with all the sensors and fetch in the path on sampler, have guaranteed the consistance of sampling.For strengthening the processing power to measurement data, the peripheral hardware of microprocessor has designed printer and serial ports.For making things convenient for the man-machine communication, adopted colored demonstration touch screen technology.Show it is in the time of the multiparameter curve in order to satisfy on-the-spot requirement.This instrument carries printer and serial ports, and data can print does the papery archives, also can be uploaded to computing machine with serial ports and do the electronics shelves; This instrument has also adopted colored demonstration touch screen technology, and man-machine interface is not only pure and fresh, can also realize the man-machine communication easily; In addition, the measurement curve of a plurality of parameters shows it also is big characteristics of this instrument simultaneously.
