The stator windings are wrapped with F-class epoxy mica tape and mould pressed, at the same time, adopts anticorona measure and skewed slot structure, which greatly improve the insulation efficiency, reduce the medium loss, enhance the mechanical strength and prevent from deforming.
Excitation system: the generator has adopted brushless permanent excitation. There is exciter and PMG, the exciter is inside of the generator at the inner side of the end shield and the PMG is installed outside of the end shield.
Ventilation system: the inner ventilation system is designed with a mixed style ventilation structure - wind come from both vertical and horizontal direction.
The frame is of cube type and cylinder type, which is in favor of mix ventilation system and strengthen the ventilation effect. IP23 or IP44 protection degree.
With the help of double-fed asynchronous generator's automatic lubrication system, by using America Lincoln lubricator, can realize the automatic lubrication of high-voltage generator. This lubricator is of high anti-corrosion, the stock tank is made of high-strength fiber, can provide three separated lubrication systems. With different control LCD panel available, the brake has many exits to be chosen and can be connected inside; additional three way cock is no needed.
