Main points for power selection of Cummins diesel generator

选择多大功率的康明斯柴油发电机要根据工作要求，这样选择的康明斯柴油发电机才符合工作，那么怎么选择康明斯柴油发电机功率的大小呢。功率有长行（额定）功率和后备功率之分，长行功率为康明斯柴油发电机可以连续12小时运行的功率，而后备功率只能在12小时连续运行中运行一小时。The power of Cummins diesel generator shall be selected according to the work requirements. In this way, the Cummins diesel generator can meet the work requirements. How to select the power of Cummins diesel generator. The power can be divided into long-term (rated) power and backup power. The long-term power is the power that Cummins diesel generator can operate for 12 hours continuously, while the backup power can only operate for one hour during 12 hours of continuous operation.
To determine the power of Cummins diesel generator is not to simply add up the power of all electrical appliances, but also to consider the starting mode of electrical appliances. Generally, the starting mode is divided into direct starting, step-down starting or variable frequency starting. The starting current of the former is about 6 times of the working current, and the instantaneous power will also reach 6 times of the rated power.
The starting current of the latter is about 3 times, and the instantaneous power is also 3 times of the rated power. Therefore, when selecting the power of Cummins diesel generator, in addition to the sum of the power of all consumers, it is also necessary to consider the starting power of each consumer.
