V. FAQs on Trailer Generator Sets
1. How to select the appropriate power rating for a trailer generator set? What key factors should be considered?
First, total load power: Calculate the combined power consumption of all electrical equipment, accounting for 3-7 times the starting current requirement for voltage-reducing and variable-frequency starting devices.
Second, operating duration: For daily use around 8 hours, select a prime power unit; for 3-4 hours, choose a standby unit. It is recommended to keep the load power at 70%-80% of the unit's actual power to balance fuel economy and equipment lifespan.
Third, application scenarios: For high-power demands like infrastructure construction or emergencies, select units with hundreds of kilowatts; for outdoor performances or field research, choose units with tens of kilowatts. Explosion-proof devices must be added for high-risk environments.
2. What is the difference between the prime power and standby power of a trailer generator set?
Prime power refers to the rated power at which the unit can operate continuously for extended periods (typically over 8 hours daily). Standby power denotes the maximum power the unit can deliver during emergency situations for short-term operation (not exceeding 1 hour per instance, with a daily cumulative limit of 3 hours), usually 10%-20% higher than prime power. For example, a 200kW rated power unit may have a standby power of 230kW. This standby capacity is only suitable for emergency scenarios like sudden power outages and should not be used for prolonged operation, as it accelerates equipment wear.
3. What are the key frost prevention techniques for using trailer generator sets in winter?
First, promptly drain all coolant after shutdown to prevent ice expansion from damaging the engine block. Before draining, allow the unit to idle at low speed to cool down gradually, preventing sudden temperature changes that could cause deformation or cracking of cylinder heads and blocks.
Second, add antifreeze to the cooling system to prevent freezing at the source.
Third, during long-term storage, periodically start the unit for no-load operation to prevent component rust and aging. Simultaneously check the antifreeze level to ensure effective freeze protection.
