OPEN FRAME DIESEL GENERATOR 4
What is an open-frame diesel generator set?
1.Definition
Open-frame diesel generator set is a common power generation equipment. It is mainly composed of diesel engine, generator, control screen and chassis. Compared with other types of generator sets, the main components such as the engine and generator are open-mounted on a simple frame (chassis) without a closed shell, which is also the origin of the "open frame" name.
2.Design feature
Diesel engine: is the power source of the generator set, generally for the high-speed diesel engine, through the combustion of diesel oil to generate power, drive the generator to generate electricity. For example, the common four-stroke diesel engine works through four stroke cycles of intake, compression, work and exhaust.
Generator: usually a synchronous generator, which uses the principle of electromagnetic induction to convert the mechanical energy from the engine into electricity. The stator and the rotor of the generator are the key components. The stator winding produces an induced electromotive force, and the rotor provides a rotating magnetic field.
Control panel: It is used to control and monitor the operating status of the generator set. Can start, stop the operation, but also can display the voltage, current, frequency, power and other parameters, and with overload, short circuit and other protection functions.
Chassis: it acts to support and fix the engine, generator and other components. Generally made of steel, with a certain strength and stability, and easy to transport and installation.
3. Operational principle
When the diesel engine is started, the crankshaft rotation drives the rotor of the generator, making the stator winding of the generator cut the magnetic line of the rotor magnetic field, thus generating the induced electromotive force in the stator winding. If the external circuit is closed, there will be a current output. According to the law of electromagnetic induction (which is the induction electromotive force, the strength of the magnetic field, the length of the wire, the movement speed of the wire, and the Angle between the movement direction and the magnetic field direction), the power generation process of the generator can be understood.
4. Application scenarios
Construction site: to provide temporary power for all kinds of construction equipment such as welding machine, power tools, etc. Because the construction site environment is relatively complex, the open-frame structure is easy to heat dissipation and maintenance, and can be moved flexibly, to adapt to the electricity demand of different construction stages.
Outdoor activities: such as outdoor music festivals, sports events and other occasions, used to provide stage lighting, sound systems, electronic scoring equipment, etc. Its ease of transportation and rapid installation makes it an ideal choice for temporary emergency power generation.
Emergency backup power supply: In hospitals, data centers and other places, when the mains power is out, the open-frame diesel generator set can be started quickly, to provide backup power for important equipment and facilities and ensure the normal operation of basic functions.
