Description
Technical field
The utility model provides a kind of automatic volume displaced type vacuum degasser for transformer oil, belongs to power system automatic field.
Background technology
At present, increasing power transformer begins to install online gas chromatography system, the on-line chromatograph system can continuous, real-time, online, automatic Transformer Oil Analysis in the content and the rate of growth of dissolved gas, transformer fault is carried out automatic diagnosis.And the characteristic gas that the object that the on-line chromatograph system is analyzed is promptly gathered from the transformer oil degasser.Main transformer oil degas method mainly contains following 2 kinds at present: the one, and the vibration degassing method, it is a kind of method that generally adopts, the oil sample of syringe collection need be carried out aerating, constant temperature, vibration in advance, make to reach gas-liquid volume equilibrium state in the syringe, extract a certain amount of characteristic gas injection chromatographic system then and analyze.The shortcoming of this method is prior vibration, constant temperature and Balance Treatment to sample oil, time-consuming, effort, and be not suitable for the on-line chromatograph analysis; The 2nd, the vacuum outgas method, it mainly is reducing piston vacuum outgas method, need to use vacuum pump and reducing piston, earlier with vacuum pump to system's extracting vacuum, sample oil enters behind the degas chamber in the oil gas and can separate out, utilize vacuum pump as drive power source reducing piston characteristic gas in the degas chamber to be transferred to discharge this moment again, but characteristic gas can not thoroughly be gathered in the degas chamber, must use the gas washing technology, thereby characteristic gas effective concentration is reduced, be unfavorable for improving the sensitivity for analysis of on-line chromatograph, and use the vacuum pump noise big, the length that expends time in, efficiency ratio is lower.
The utility model content
The purpose of this utility model provides a kind ofly can overcome above-mentioned defective, improve degassing efficiency, accelerate degassing rate, and can realize automatically outgasing and the fully automatic vacuum degasser that effectively is connected with on-line chromatograph.Its technology contents is:
A kind of automatic volume displaced type vacuum degasser for transformer oil, it is characterized in that: comprise sample oil injector, the sample gas quantity tube, gas shifts cylinder, the gas exchange cylinder, oil sample degassing cylinder, draining valve F1 and some solenoid valves, the outlet of sample oil injector connects oil sample degassing cylinder respectively by the pipeline that is provided with the second solenoid valve F2, draining valve F1 and the 3rd solenoid valve F3, the other end of the 3rd solenoid valve F3 meets gas exchange cylinder and the 4th solenoid valve F4 respectively, the other end of the 4th solenoid valve F4 connects gas respectively and shifts cylinder and the 5th solenoid valve F5, the other end of the 5th solenoid valve F5 meets sample gas quantity tube and the 7th solenoid valve F7 respectively, the other end UNICOM carrier gas of the 7th solenoid valve F7, the outlet of sample gas quantity tube is provided with the 6th solenoid valve F6.
Described automatic volume displaced type vacuum degasser for transformer oil, sample oil injector is glass syringe or other quantitative sample injection device.
Its principle of work is: the inlet that gas shifts cylinder, gas exchange cylinder, oil sample degassing cylinder all is arranged on separately piston away from a side of piston rod.Open the second solenoid valve F2, other closed electromagnetic valve, the piston of vacuum outgas cylinder outwards moves, oil sample in the sample oil injector 1 is sucked oil sample degassing cylinder, stop the piston operation of oil sample degassing cylinder then, close the second solenoid valve F2, open the 3rd solenoid valve F3, the piston that starts the gas exchange cylinder outwards moves fast, the inner high vacuum that forms rapidly of an end that is connected with oil sample degassing cylinder in the gas exchange cylinder, contained sample gas is deviate from rapidly, close the 3rd solenoid valve F3, open the 4th solenoid valve F4, the piston that starts the gas exchange cylinder moves inwards, and the piston that the interior gas promotion of gas exchange cylinder this moment gas shifts cylinder outwards moves.When the piston arrives top of gas exchange cylinder, sample gas is shifted in the cylinders by whole injecting gas in the gas exchange cylinder.Close the 4th solenoid valve F4, open the 5th solenoid valve F5, the piston that starts gas transfer cylinder moves inwards, makes gas shift the interior sample gas of cylinder and all enters the sample gas quantity tube, closes the 5th solenoid valve F5.Open the 6th solenoid valve F6 and the 7th solenoid valve F7, carrier gas (is generally N
2) promote sample gas in the sample gas quantity tube through the 7th solenoid valve F7 and output to the on-line chromatograph system by the 6th solenoid valve F6 and carry out the gas composition analysis.
The utility model compared with prior art, the fully automatic vacuum degasser utilizes cylinder that sample oil is carried out vacuum outgas, degasification process is simple, the degassing efficiency height can reach more than 90%, and degassing rate is fast, whole degasification process just can be finished with interior at 5 minutes, shortened the working time greatly, improved work efficiency, is greatly improved the serviceable life of device.
