Detailed Product Description: | Basic principle of operation - Bing spot guidance | Nanjing generator leasing basic principle of operation: diesel engine driven generator running, this is fundamental. Diesel energy into electrical energy. The cylinder of the diesel engine through the air cleaner clean filtered air and a high-pressure atomizing nozzle injected diesel mix, extruding the piston upward, the volume reduced, rapid temperature rise, to diesel fuel ignition. Diesel fuel was ignited, severe burning gas mixture, rapid expansion of volume, push the piston down, called for power. Each cylinder for a certain order of power, acting on the piston rod thrust into a push through the power of crankshaft rotation, so as to drive the crankshaft rotates. The brushless synchronous AC generator and diesel engine crankshaft coaxial installation, you can use the diesel engine driven generator rotor rotation, the use of electromagnetic induction principle, the generator will output the induced electromotive force, the closed loop will be able to generate the load current. It only describes the basic working principle of generator sets. To be usable, stable power output, but also a series of diesel engines and generator control, web design and circuit protection devices. Generator is not connected load, the armature current is zero, called the no-load operation. At this point of the three-phase stator winding excitation current If only no-load electromotive force induced in E0 (three phase), with If the size of the increases. However, since the motor magnetic core has saturated phenomenon, so the two are not directly proportional. Reflect the load emf E0 and excitation current If the relationship curve is called synchronous generator load characteristics. Load operating characteristics, mainly refers to the external characteristics and adjustment features. External characteristic is that when speed is rated, the excitation current and load power factor is constant, the generator terminal voltage U and the load current I relationship. Adjust feature is the rated speed and the terminal voltage, the load power factor is constant, the field current If and the relationship between the load current I. Synchronous generator voltage change rate of about 20 ~ 40%. General industrial and household loads are required voltage remains basically unchanged. Therefore, as the load current increases, the excitation current must be adjusted accordingly. Although the trend of adjustment features and external features just the opposite, for purely resistive and inductive loads, it is rising, while the capacitive load is generally declining.
