The diesel generator group is a kind of independent power generating equipment. It refers to the power machinery which uses diesel engine as the prime mover to drive the generator to generate electricity. The whole unit is generally composed of diesel engine, generator, control box, fuel tank, starting and control battery, protective cover, emergency cabinet and other components. The whole body can be fixed on the foundation, positioned for use, or mounted on a trailer, altogether moving for use.
The diesel generator is a non-continuous operation power generating equipment. If it is operated continuously for more than 12 hours, its output power will be about 90% lower than the rated power. Although the power of the diesel generator is relatively low, it is small, flexible, portable and fully equipped for easy operation and maintenance, so widely used in mines, railways, field sites, road traffic maintenance, as well as factories, enterprises, hospitals and other departments, as a backup power or temporary power supply. The small electric generator can also be used as small mobile power plants, which can serve as back-up power supplies for many businesses.
