What are the requirements for cold water quality in generators in the “Electric Power Industry Techn

According to Article 3-10-9 of the “Technical Management Regulations of the Electric Power Industry”, measures must be taken for the quality of the cooling water of water-cooled generators ( including condensers) in order to avoid corrosion and clogging of hollow wires (copper). The copper and iron content of the open system outlet water must meet the water quality requirements. At the same time: the conductivity (25°C) must not be greater than 10 microns/cm; 10 microgram equivalents/liter; the pH value should be between 8.0 and 8.5.

Should replacing generator gas be replaced with internal cold water? Why?

Although hydrogen enters the generator after passing through a dryer, there will always be a certain amount of moisture, so cold water used in the generator is necessary. The temperature must be higher than the temperature of the hydrogen, otherwise theHydrogen will condense when it gets cold, because water is not allowed in the generator.

Generators are mechanical devices that convert other forms of energy into electrical energy. They are driven by water turbines, steam turbines, diesel engines or other electrical machines to convert water flow, air flow. , fuel combustion or atomic nuclei The energy produced by fission is converted into mechanical energy and transmitted to the generator, which is then converted into electrical energy. Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life.

If the copper in the generator cooling water is high, should the conductivity be high

Please describe the problem in detail

The cooling water in the generator must be switched to protectthe generator. Generator gas replacement refers to the replacement of gas inside the generator to achieve the purpose of generator protection. When replacing gas, directly injecting compressed air or nitrogen into the generator will cause the internal temperature of the generator to increase, thereby increasing the thermal load of the generator and damaging the generator. Therefore, when replacing gas, cooling is necessary to maintain a stable temperature inside the generator.
