The History of the Generator
The working principle of the generator set is that the generator runs continuously under the drive of the prime mover, so as to achieve the purpose of generating electricity. For example, in the cylinder of diesel generating sets, air after air cleaner filter becomes clean air, generator set, breathing fresh air inlet valve is opened, the valve is turned off, push on the piston compressed air, when the piston reaches the top dead center nozzle jet atomization diesel, the fresh air in the original compressed in the cylinder pressure, high temperature, Diesel fuel will be directly burned after ejection, burning gas volume expansion, push the piston downward motion, finally exhaust valve open, exhaust gas after combustion. The cylinders of each generator set repeat this up and down motion in turn, which drives the crank shaft of the generator set to rotate.
Generator set belongs to a type of self-contained power station AC emergency power supply equipment, it is an independent small power generation equipment, with diesel engine as the power, drive synchronous alternator and generate electricity. It is composed of diesel engine (small gasoline engine), generator, control panel, common base and other components. They are typically installed in hospitals, telecommunications rooms, data centers, factories, nuclear power plants, or key defense and government facilities for use when external power supplies are interrupted. Since generating sets take time to start up, they are often equipped with battery packs to maintain continuous and stable power supply.
Some generators can be moved, for example by vehicle transport or towing, and small generators can be hand-held or wheeled. These units can be used temporarily or in areas where electricity supply is inaccessible.
Alternating current generator
When electromagnetic induction was discovered, the method of generating alternating current was known. Early products were developed by Michael Faraday and Pollitt Pixie, among others.
In 1866, Werner von Siemens proposed the working principle of the electric generator, and a Siemens engineer completed the first human alternator.
In 1882, British electrician James Gordon built the large dual-phase alternator. Lord Kelvin and Sebastian Ferranti developed early alternators with frequencies between 100 Hz and 300 Hz.
In 1891, Nikola Tesla patented a "high frequency" (15,000 Hertz) alternator.
After 1891, multiphase alternators were used to supply current. Since then, alternators have been designed with alternating current frequencies between 16 Hz and 100 Hz and are used with arc lamps, incandescent lamps, or electric motors.
When the magnetic field around a conductor changes, an induced current is generated in the conductor. Normally, a rotating magnet is called a rotor, and a fixed set of conductors, called a stator, wrapped in a coil on an iron core, generates an electric current as it crosses a magnetic field.
Direct current generator
A DC generator is a generator that converts mechanical energy into direct current.
In 1866 Werner von Siemens and other Siemens engineers invented the first direct current electric generator.
In 1882, the Edison Electric Light Company built its third power station in London, installing three 110-volt DC generators capable of powering 1,500 16-watt incandescent lamps.
With the popularity of alternating current, large DC generators have become a thing of the past. Now, if direct current is needed, a rectifier is used to rectifying the alternating current into direct current.
