The meaning of qfsn2-660-2 generator is: QF stands for steam turbine generator; S represents the internal water cooling of the stator; 660MW rated capacity is 2 represents this type. The generator is a three-phase AC bipolar synchronous generator. The generator adopts water-hydrogen cooling method, that is, the stator winding is water-cooled, the rotor winding is hydrogen-cooled, and the stator core and parts structural are water cooled. cooled with hydrogen.
What are the methods of cooling turbine exhaust steam?
Although hydrogen enters the generator after passing through a dryer, there will always be a certain amount of humidity, so the temperature of the cold water used in the generator must be higher than the hydrogen temperature. , otherwise the hydrogen will condense when it is cold, because the water is notnot allowed inside 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.
What are the dangers of replenishing hydrogen in the generator too quickly?
There are mainly two methods: water cooling and air cooling. Water cooling refers to the use of circulating water. louser cool through the condenser tube bundle. The steam turbine exhaust steam is suitable for places with abundant water resources. Air cooling is mainly suitable for places with abundant wind resources and lack of water resources. It mainly uses wind to cool exhaust steam from steam turbines.
Equipment easy to damage. From the generator's operating instructions, it can be seen that if the generator replenishes hydrogen too quickly, it will easily damage the equipment. Generators refer to mechanical equipment that converts other forms of energy into electrical energy. It is driven by water turbine, steam turbine, diesel engine or other electrical machines and converts energy generated by water flow, air flow, fuel combustion or nuclear fission . in mechanical energy and transmits it to the generatorr of the machine, which is then converted into electrical energy.
