Abstract
Disclosed is a instrument for measuring PH value of water-soluble acidity of in-service transformer oil and steam turbine oil, in particular the instrument is capable of transferring colors of PH standard color grade into corresponding 256 grade R, G, B chromatic digital signal for permanent storage via a chromatic light/ frequency converter, and is capable of transferring extracting fluid from water of transformer oil and steam turbine oil and colors of color-matching glass container of indicator into corresponding 256 grade R, G, B chromatic digital signal via the chromatic photo-converter or the frequency changer to compare and determine PH of water of transformer oil and steam turbine oil by comparing with digital signal of standard color grade. The instrument is composed of six portions of a white illuminating source, an optical element, a colorimetric glass container, a chromatic light/ frequency converter, a single chip device and a display and ancillary equipment, wherein the colorimetric glass container and the chromatic light/ frequency converter are arranged on the same axial trace in a line and are kept in a space distance no more than 29 millimeters. Through combination of the colorimetric glass container and the digital style chromatic light/ frequency converter, conventional method of distinguishing fluid colors by eyes is changed, thereby eliminating interference of color changing, production of floccules and the like of standard color gradation due to reasons of long-term storage, light strike and the like, and reducing systematical errors.
Description
Affiliated technical field
The utility model relates to a kind of instrument that the water soluble acid pH value of transformer oil in service, steam turbine oil is measured, and especially can PH standard colors level color conversion be carried out permanent storage for corresponding with it 256 grades of R, G, B colorful digital signal by colorama/frequency converter; Can be corresponding with it 256 grades of R, G, B colorful digital signal by the colorimetric glass container color conversion that colorama/frequency converter will add transformer oil, steam turbine profit Extract and indicator, through comparing to determine its pH value with standard colors stages of digital signal.
Background technology
At present, known transformer oil in service, steam turbine oil water soluble acid determination method are the artificial visual colourimetrys.Method is to mix with isopyknic distilled water and test specimen to shake, get its water Extract, contain in the colorimetric glass container after adding bromcresol purple or bromcresol green indicator, with its be sealed in the colorimetric glass container PH standard buffer solution that adds bromcresol purple or bromcresol green indicator, promptly, judge pH value with the progressive pedestrian worker's visual colorimetric determination of PH standard colors.The standard colors level inevitably will be subjected to natural causes influences such as solar radiation and difference variation, understands progressively variable color and produces cotton-shaped impurity, influences test findings, therefore will regularly prepare and change.Owing to the difference of testing crew eyes colour vision, also can exert an influence simultaneously to test findings.
Summary of the invention
The variable color of standard colors level and testing crew eyes colour vision difference exert an influence to test findings in the existing test method in order to overcome, realize transformer oil, the purpose that steam turbine oil water soluble acid pH value detects automatically by instrument, the utility model provides a kind of transformer oil, steam turbine oil water soluble acid pH value color comparator, this instrument combines the colorimetric glass container with digital colorama/frequency converter structure, changed originally and discerned liquid color traditional method in the colorimetric glass container, realized the adding transformer oil with eyes, the colorimetric glass container color of steam turbine profit Extract and the indicator sign of RGB (RGB) colorful digital signal.
The technical scheme that its technical matters that solves the utility model adopts is:
This instrument is made up of white light source, optical element, colorimetric glass container, colorama/frequency converter, single-chip microcomputer, demonstration and utility appliance six parts.White light source, optical element, colorimetric glass container, colorama/frequency converter are emitted on the same geometrical axis successively, keep being not more than 29 millimeters space lengths between colorimetric glass container and colorama/frequency converter.The light that white light source sends forms light beam through behind the optical element, vertical irradiation was on colorama/frequency converter after light beam passed colorimetric glass container center, colorama/frequency converter is converted to redness, green and blueness respective frequencies signal separately with incident beam, obtains corresponding with it 256 grades of R, G, B colorful digital signal through single-chip microcomputer sampling, analysis.Each PH standard colors level that at first will be sealed in the colorimetric glass container detects one by one, corresponding 256 grades of R, G with each PH numerical value, B colorful digital signal are stored successively, water Extract with transformer oil, steam turbine oil sample injects the colorimetric glass container then, adding bromcresol purple or bromcresol green indicator also fully mixes, detect corresponding with it 256 grades of R, G, B colorful digital signal, through comparing to determine its pH value and select the indicator type for use, inform testing crew by demonstration and utility appliance at last with standard colors stages of digital signal.
The beneficial effects of the utility model are, PH standard colors level color conversion is carried out permanent storage for corresponding with it 256 grades of R, G, B colorful digital signal, realized the automatic detection of transformer oil, steam turbine oil water soluble acid pH value, eliminate interference such as the color change that the standard color range causes because of reasons such as long-term storage, solar radiations, generation floccus, reduced systematic error.
