سادسا. القضايا المشتركة
س1: Why is the voltage of a high-voltage generator set 10.5 kV instead of 10 كيلو فولت?
أ: 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?
أ: Huaquan Power recommends referring to the following standards:
| Your request | الحل الموصى به | سبب |
| Single unit power < 500 كيلوواط | Low-voltage unit (400V) | Low-voltage equipment is mature and low-cost |

| Single unit power > 1000 كيلوواط | High-voltage unit (10.5كيلو فولت) | الجهد العالي والتيار المنخفض, with a more reasonable equipment capacity |
| The distance between the load and the generator is greater than 1000 متر | High-voltage unit (10.5كيلو فولت) | The loss of power transmission over long distances is small |
| Data center/Medical center | High-voltage unit (10.5كيلو فولت) | Centralized power supply, دقة تنظيم الجهد العالي |
| 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 |
