DIGITAL FREQUENCY CONVERSION SILENT DIESEL GENERATOR
What is the diesel digital frequency conversion generator set?
1. definition
Diesel digital frequency generator set is a kind of power generation equipment that combines diesel engine and digital frequency generator set. It uses diesel as fuel, generates power through the combustion of diesel engines, drives the generator to generate electricity, and is equipped with digital frequency conversion technology.
2. operational principle
Diesel engine work: diesel oil burns in the engine cylinder, producing high temperature and high pressure gas, pushing the piston to do work. The reciprocating movement of the piston converts the crankshaft through the chemical energy into mechanical energy.
Generator work: the rotating crankshaft drives the rotor of the generator to rotate, making the magnetic flux in the stator winding change, thus generating the induced electromotive force. According to the law of electromagnetic induction, when the conductor moves in a magnetic field, and generates a current when the external circuit is closed.
Digital frequency conversion technology: the frequency converter in the digital frequency conversion generator set processes the alternating current output of the generator. It can accurately control the output voltage and frequency of the generator, and convert the original AC generated by the generator into stable AC that meets specific requirements. For example, it can stabilize the voltage at the standard voltage values such as 220V or 380V, and stabilize the frequency at 50H [] z or 60H [] z.
2. main unit
Diesel engine: it is a power source, and its performance directly affects the power output of the generator set. Diesel digital frequency conversion generator sets of different power are equipped with diesel engine power is also different, generally including single-cylinder and multi-cylinder engines. Single-cylinder engine is simple structure, low cost, suitable for low power demand; multi-cylinder engine operation is more stable, large power, suitable for industrial and other high power requirements.
Generator: usually use synchronous generator, its stator and rotor structure design helps to produce a stable alternating current. The difference between digital frequency conversion generator and ordinary generator lies in its internal electronic control module, which can realize the accurate modulation of the output electric energy.
Frequency converter: this is the key component of the digital frequency conversion generator set. It can monitor and adjust the output voltage and frequency of the generator in real time. When the load changes, the frequency converter can react quickly to keep the output voltage and frequency stable. For example, when the connected electrical equipment starts the instantaneous current increases, the frequency converter will automatically adjust the output of the generator to avoid a large drop in voltage.
Control panel: The user can operate the generator set through the control panel, such as starting, stopping, adjusting the output voltage and frequency. The control panel usually also displays the operating state parameters of the generator set, such as engine speed, water temperature, oil temperature, output voltage, output current, etc., which is convenient for users to monitor.
3.characteristic
High output power quality: digital frequency conversion technology makes the output AC frequency stable, waveform distortion rate low, can power the precision electronic equipment with high requirements for power quality, such as computers, servers, medical equipment, etc. Compared with the traditional generator set, the output voltage fluctuation range is small, and it can generally be stable within ± 1% of the rated voltage.
Good fuel economy: With precise engine speed and output power control, the diesel digital variable frequency generator set can optimize fuel consumption under different load conditions. In low load operation, its fuel saving effect is more obvious, which can effectively reduce the operating cost.
Low noise: due to the use of advanced engine technology and sound insulation measures, coupled with the digital frequency conversion system to control the engine speed reasonably, make the noise of the generator set in the operation process is effectively reduced. Generally speaking, its noise level is about 10-15 decibels lower than that of traditional generator sets, which is more suitable for use in the environment with strict requirements on noise, such as residential areas, hospitals, schools, etc.
4. application scenarios
Home standby power supply: provide emergency power for electrical equipment in the family during power failure, and ensure the operation of basic living electricity, such as lighting, refrigerator, TV and other equipment.
Outdoor activities: in the outdoor camping, RV travel and other activities, to provide power for a variety of electrical equipment, including electric oven, small air conditioning, etc.
Commercial places: small shops, restaurants, etc., can use diesel digital frequency conversion generator set to maintain basic business activities, such as cash register, lighting system and so on.
Industrial field: for some industrial production links with high requirements for power supply stability and relatively small power capacity demand, such as small processing workshops, communication base stations, etc., it can also be used as backup power supply or temporary power supply.
