After the calculation method is proved correct by experimental results, this calculation method is used to calculate the flow velocity distribution of the outlets of multiple radial ventilation ducts at various flow
(42) Install ac and dc conduit above generator in accordance with paragraph 4-35 of the Operator and Organizational Maintenance Manual.
Ventilation air inlets and outlets should be positioned to prevent pockets of stagnant or recirculating air, especially in the vicinity of the generator air inlet.
There are many sensors available for dynamic monitoring of the air gap when the generator is rotating. However, typical tools for static measurement of the air gap prior to generator rotation called
Since the air gap is a central part of the motor or generator and is the interface between mechanical and electrical forces, it is straightforward to identify problems by monitoring them.
Just like in the main generator, the voltage waveforms will be distorted, plenty of harmonics and electrical vibration in the exciter rotor (though it won''t affect the bigger animal). Not
Whenever possible, use no ductwork at all. Simply position the inlet air duct so that air will be drawn directly over the generator and expelled horizontally to the building exterior (outdoors).
The temperature distribution of the iron core and air gap in the air duct is obtained by calculation. The results show that the design of air duct can effectively reduce the temperature rise of
10 mm and upwards. Unlike conventional inspection devices, which are restricted to turbo/hydro generators with very large air gaps, ABB Air Gap Inspector can be used on all synchronous motors
An air gap is a crucial parameter in hydroelectric generators, measuring the distance between the rotor and stator. This small distance is essential for preventing damage and maintaining
