1. The turbine generator of the power plant is installed on the "operating platform". Under the air-cooled generator, there is a "generator air-cooling room", in which you can see the "tail" of the generator stator coil, and also It is a "neutral point" where the three-phase stator windings are connected.
2. Turbine generator refers to a generator driven by a steam turbine. The superheated steam generated by the boiler enters the steam turbine and expands to do work, causing the blades to rotate and drive the generator to generate electricity. The waste steam after the work is returned to the boiler for recycling through the condenser, circulating water pump, condensate water pump, feed water heating device, etc.
3. The IEC standard calls the conductor carrying multi-phase unbalanced current the neutral line (N line), which is often referred to as the "neutral line".
Do air-cooling units and water-cooling units refer to cooling steam turbines? For example, the exhaust steam of the steam turbine is cooled with water, and the generator is cooled with air.
CB steam turbines are generally equipped with coolers.
CB steam turbine is a rotating generator that usually has the characteristics of high-speed rotation and high temperature, so it must be effectively cooled. According to the manufacturer's information and relevant instructions, CB steam turbines are generally equipped with a cooling system to ensure stable operation. Cooling methods usually use different methods such as water cooling, air cooling or hydrogen cooling, depending on multiple factors such as machine model, equipment specifications and usage environment.
When using a CB steam turbine, not only does it need to be installed and debugged correctly in accordance with the manufacturer's equipment requirements, but the cooling system also needs to be regularly maintained and inspected. To ensure the long-term, stable and efficient operation of CB steam turbine.
What kind of generator is divided into what kind of generator?
We now say that a thermal power generating unit is air-cooled or water-cooled, which refers to the cooling method of the steam turbine exhaust steam. If it is If the steam enters the condenser and is cooled with water, then it is a water-cooled unit. If the exhaust steam is led to an air-cooling device and cooled with air, then it is an air-cooled unit. It has nothing to do with the cooling method of the generator itself. If the generator is air-cooled, then the generator is said to be an air-cooled generator, not an air-cooled unit. Therefore, if the steam turbine is water-cooled and the generator is air-cooled, the unit is still a water-cooled unit and the generator is an air-cooled generator.
