VI.Common Issues
Q1: Why is the voltage of a high-voltage generator set 10.5 kV instead of 10 kV?
UM: The rated voltage of a generator is usually 5% higher than the rated voltage of the power grid to compensate for voltage drops on the transmission lines. When the rated voltage of the power grid is 10kV, the rated voltage of the generator is designed to be 10.5kV. When the 10.5kV output reaches the user end through the transmission lines, the voltage drops to around 10kV, ensuring normal operation of the equipment.
Q2: Which is more suitable for me, a high-voltage generator set or a low-voltage one?
UM: Huaquan Power recommends referring to the following standards:
| Your request | Recommended Solution | reason |
| Single unit power < 500 kW | Low-voltage unit (400V) | Low-voltage equipment is mature and low-cost |
| The distance between the load and the generator is less than 500 metros | Low-voltage unit (400V) | Line loss is acceptable |
| Single unit power > 1000 kW | High-voltage unit (10.5kV) | Alta tensão e baixa corrente, with a more reasonable equipment capacity |
| The distance between the load and the generator is greater than 1000 metros | High-voltage unit (10.5kV) | The loss of power transmission over long distances is small |
| Data center/Medical center | High-voltage unit (10.5kV) | Centralized power supply, precisão de regulação de alta tensão |
| Multiple high-power units operating in parallel | High-voltage unit (6kV/10.5kV) | The parallel operation system is mature and has strong harmonic suppression capability |
Q3: What are the protection level and insulation level of Huaquan high-voltage generator sets?
UM: Huaquan’s high-voltage Geradores have a protection level up to IP23 (rain-proof) and an insulation level of H. The containerized units have a higher protection level and can be used outdoors in all weather conditions.
Q4: What is the service life of a high-voltage generator set?
UM: The design lifespan of Huaquan high-voltage generator sets is over 20 anos, with the generator bearings having a lifespan of over 100,000 horas. The engine, when maintained according to specifications, can undergo a major overhaul after 30,000 horas.
Q5: What are some successful cases of Huaquan high-voltage generator sets?
