1) Excessive conductivity will cause large leakage current, thereby aging the insulated water pipe and causing flashover between stator phases.
2) The hardness of the cold water in the stator is too large, causing scale on the inner wall of the cooling tube in the hot state, reducing the cooling effect and even blocking it.
3) Copper pipes are subject to corrosion.
In order to ensure the safe operation of the generator.
The conductivity of cold water in the power plant cannot be less than 0.5 to ensure the safe operation of the generator. Because the conductivity of water is high, the leakage current is large. generator loss will also increase and accelerate. Corrosion of copper wires can easily cause breakdown, so the conductivity of cold water cannot be less than 0.5.
Conductivity,a physical concept, can also be called conductivity. The product of this quantity and the intensity of the electric field E in the medium is equal to the conduction current density J.
