Technical Characteristics
Stator of High Voltage Generator
Class F stator is wrapped with class F epoxy mica tape and mould pressed. Class H stator coil is operated with the mature class H insulation technology and impregnated in VPI (vacuum pressure impregnating) system. Both class F and class H stator coil are processed with anti-corona treatment. Meantime, the stator coil is designed with skewed slot structure to effectively reduce harmonic wave. Enhance the mechanical strength on the end of stator winding to effectively prevent and withstand the deformation on the end of stator caused by the sudden load or short circuit.
Rotor of High Voltage Generator
Triple insulated structure of the rotor coil can effectively improve the rotor turn to turn and interlayer insulation, the damp-proof and anti-corrosion ability. It will enhance the mechanical strength on the end of the winding to prevent the rotor winding from deforming under high rotation speed. Accordingly, the lifespan, reliability and environment adaptability of generator is also substantially improved. The rotating rectifier is designed as bi-section structure which is convenient for maintenance and do not require any knock down on the generator.
Winding
5/6 or 2/3 pitch option can decrease the content of voltage harmonic wave and is suitable for nonlinear load application. The standard configuration is temperature sensor, PT100 and space heater
