Description
Technical field：
This utility model is related to a kind of electric generator inner cooling moisture film Purification of alkali control process device.
Background technology：
Have that single-machine capacity is big due to water-cooled generator, small volume, lightweight the features such as, therefore, in high-rating generator
It is used widely in group.Water-cooled generator group is too numerous to enumerate because of the accident caused by inner cold water water quality inferiority, in order to prevent here
The generation of class accident, both at home and abroad the corrosion mechanism to inner cold water water quality and copper and anti-corrosion method carry out numerous studies it was therefore concluded that：
A. inner cold water electrical conductivity is lower, and electrical insulation properties are better, and the insulation faults such as electric flashover will not occur；B. copper corrosion is basic
Reason is to there is dissolved oxygen and dissolved carbon dioxide in inner cold water, and the bivalent cupric ion producing in corrosion process in addition is to corruption
Erosion has acceleration；C. corrosion product enters inner cold water, is stopped by generator field and deposits, may lead in stator bar
Hollow core conductor is gradually blocked by copper corrosion product or flow area reduces, and causes generator coil temperature to rise, or even scaling loss.
Water-cooled generator hollow wire generally uses industrial pure copper manufacture.Corrosion speed in oxygen-free water for the fine copper
Degree is very low, only 10-4g/(m2H) the order of magnitude.Carbon dioxide and dissolving is contained due to filling in electric generator inner cooling water
Oxygen, makes water be in subacidity, and in aerobic, the corrosion rate of copper just greatly increases.Here it is due in water free two
Carbonoxide destroys the protecting film on copper surface, longer with the unit operation time, and the stripping quantity of copper is gradually increased.Cold in finding
The water system copper content rate of climb is very fast and higher, and just the water- cooling generator in explanation stator bar occurs serious electrochemistry
Corrosion.Copper pipe surface after corrosion exposes the color of matrix copper alloy, but no metallic luster, and surface is substantially smooth or slightly concavo-convex
Injustice, tube wall is bright fresh thinning, the pattern in homogeneous corrosion.
In addition, the corrosion product that electrochemical corrosion key character is copper occurs packing phenomenon at electronegative potential, rotten
Erosion product is only attached on the tube wall surface of corrosion location on a small quantity, and major part all comes off from tube wall and enters cooling medium.
Stator bar is stopped by generator field and deposits, thus leading to hollow wire gradually to be blocked by Cu oxide or through-flow face
Amass and diminish, cause stator coil temperature to raise, some copper dirts peel off and may block bar especially during Unit Commitment
Circulation part, makes to be blocked coil or iron core temperature raises and even burns.Its harm has at 2 points：The corrosion rate of usual copper is with temperature
That spends increases and rapidly increases.Therefore, coil temperature raises, and can lead to the accelerated corrosion of copper.If do not controlled early, it will cause
Electromotor bar hot-spot and damage, severe patient insulation breakdown causes ground fault.Therefore, control the corrosion of copper, prevent copper
The deposition of corrosion product is to ensure that the important measures that engine health runs.
Content of the invention：
