1) Technical Performance:
insulation and protection
Adopting high grade insulation paint and advanced impregnating technology with multiple layer insulation protection to stator & rotor assembly, H class insulation system ensures the generator can withstand harsh environment conditions.
Patent technology
Patent technology of stator winding structure (SWS):
Enhance the inter-phase insulation strength at the end of winding to protect any short circuit problem among each phase. Enhance the mechanical strength at the end of winding to effectively prevent and withstand the deformation at the end of stator caused by sudden load or short circuit.
Patent technology of rotor insulation structure (RIS):
Patent triple insulated structure of rotor coil can effectively improve the rotor turn to turn and interlayer insulation, accordingly the damp-proof and anti-corrosion ability, the life span, reliability and environment adaptability of generators is also substantially improved.
Winding
The design of 2/3 pitch structure can decrease the harmonic and meet the non-linear load application.
Rated voltage, Frequency and Parallel Operation
50Hz — 380V-440V(Y);220V-254V(Δ)
60Hz — 380V-480V(Y);220V-277V(Δ)
With rated frequency at 50Hz or 60Hz, N series low voltage generator can operate in parallel with the same type generator.
excitation system
The standard configuration is self-excited brushless excitation system and steady state voltage regulation≤±1%. For PMG excitation system, the accuracy of steady voltage regulation ≤± 0.5%.
