Description
Technical field
The utility model relates to a kind of device for direct current station conductivity meter Comparison calibration, belongs to DC converter station water quality Quality Detection technical field.
Background technology
DC converter station converter valve inner cooling water carries out ion processing by deionizer, and inner cooling water water quality is purified, and water quality Quality Detection uses online conductivity meter to detect.State's network technology supervision requires to verify conductivity meter every year.
In-line meter need be pulled down and send the unit of qualification to examine and determine by conductivity meter verification from system, but consider DC converter station converter valve inner cooling water system tightness and operational reliability, in-line meter is difficult to pull down censorship from stream valve inner cooling water system, therefore adopts the conductivity of assay approval and online conductivity meter to compare to calibrate.
Conventional comparison method: open converter valve inner cooling water water drain valve, draining, in beaker, then uses inner cold water conductivity, measured value and the in-line meter comparing in the conductivity meter measurement beaker of assay approval.There is following problems in this method: measurement data is bigger than normal, because converter valve inner cooling water water quality is pure, as its conductivity of certain current conversion station is about 0.04 μ s/cm, when discharging water to beaker, oxygen in air, carbon dioxide etc. dissolve in rapidly in water, cause the conductivity of detection high, be Measurement accuracy water quality, comparison method is improved.
In view of this, the utility model provides a kind of device for direct current station conductivity meter Comparison calibration, to solve the problem.
Summary of the invention
The purpose of this utility model is: for the deficiency of the conductivity meter Comparison calibration of routine, thus a kind of device for direct current station conductivity meter Comparison calibration is provided, add an airtight water tank, simulate online conductivity meter running environment, conductivity meter electrode inserts water tank by reserved pore and measures.
The technical scheme that the utility model adopts is: a kind of device for direct current station conductivity meter Comparison calibration, it is characterized in that, by airtight water tank, conductivity meter, water drain valve, connecting hose and drainpipe composition, concrete syndeton is: be connected with the mouth of pipe bottom airtight water tank by converter valve water-cooling generator by connecting hose, connecting hose is provided with water drain valve, airtight water tank top is provided with drainpipe, open water drain valve, converter valve inner cold water enters bottom airtight water tank, flow out from top drainpipe after being full of airtight water tank, the electrode of conductivity meter inserts airtight water tank by reserved pore and measures.
The beneficial effects of the utility model are: conductivity meter Comparison calibration device of the present utility model, valve inner cooling water is by airtight water tank, simulate online conductivity meter measurement environment, insert from top and calibrated qualified conductivity meter electrode measurement water quality, airtight water tank exists, decrease the impact of external environment condition on water quality, measurement data, close to water quality actual value, improves the accuracy of comparison.This device obtains application in current conversion station, respond well.
