Description

Generator set with intelligent short-circuit prevention function

Technical Field

The invention relates to the technical field of generator sets, in particular to an intelligent short-circuit-preventing generator set.

Background

The temperature of the generator set is rapidly increased when the volume of the diesel generator set is reduced, and the ignition point of diesel is reached. The diesel oil is ignited, the mixed gas burns vigorously, the volume expands rapidly, and the piston is pushed to move downwards, which is called 'work'. The cylinders sequentially apply work according to a certain sequence, and the thrust acting on the piston is changed into force for pushing the crankshaft to rotate through the connecting rod, so that the crankshaft is driven to rotate. By using the principle of 'electromagnetic induction', the generator outputs induced electromotive force, and current can be generated through a closed load loop. Only the most basic operating principle of the generator set will be described here. A series of diesel and generator control, protection devices and circuits are also required to obtain a usable, stable power output. The generator set is complete mechanical equipment for converting other forms of energy into electric energy, and consists of a power system, a control system, a silencing system, a damping system and an exhaust system, and is driven by a water turbine, a steam turbine, a diesel engine or other power machines to convert energy generated by water flow, air flow, fuel combustion or atomic nuclear fission into mechanical energy to be transmitted to a generator, and then the generator converts the mechanical energy into electric energy to be output to electric equipment for use. The generator has wide application in industrial and agricultural production, national defense, science and technology and daily life. The gasoline generator set is a kind of power generation equipment, which uses gasoline as fuel and is a mechanical equipment to convert other forms of energy into electric energy, and is driven by water turbine, steam turbine, diesel engine or other power machine to convert the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy for transmission.
