What Is The General Rated Capacity Of The Diesel Generator Fuel Tank?

Generally, the starting capacity of a diesel generator is only 20%-30% of its rated capacity. That is to say, the maximum capacity of the motor that can be started by a 100kw diesel generator is 20-30kw, because the throttle of the diesel generator cannot be larger. When the motor is started, it quickly opens to the correct position, so it will cause the speed of the diesel generator to drop, that is, the frequency will drop, and even the diesel engine will be suffocated to stop, and the motor starting current is 6-10 times the rated current, at such a large current Under the impact, the terminal voltage drop of the generator decreases. Of course, the excitation protection of the generator will immediately increase the excitation current, but there is a process, so when the motor starts, the diesel generator will have a voltage drop. The larger the motor , The larger the starting current, the more the voltage drops. Since the closing and closing voltage of the contactor is the circuit voltage, the generator voltage drops significantly. As a result, the contactor will lose voltage and trip due to the low closing voltage.
