With the economic development and the increasing capacity of industrial power equipment, the capacity of diesel generator sets as backup power sources is also increasing. Sometimes, multiple high-power diesel generator sets are required to be connected in parallel to meet the requirements. The voltage is also increased from the usual 400V to 6300V or 10500V. At this time, the high-voltage diesel generator set came into being, and the demand for high-voltage electrical equipment was solved in time. Because the output voltage is 10kV and the voltage of the original power supply system is the same, the high-voltage unit can directly access the power supply system, eliminating the investment in equipment for large power supply and distribution systems. At the same time, because the output voltage of the unit is high, the output current is small, and the power loss during the power transmission process is small, which is suitable for long-distance transportation. It has high voltage regulation precision, good dynamic performance, small voltage waveform distortion, high efficiency, compact structure, convenient maintenance, reliable operation, long service life and good economic performance. |
