Description

Electricity generating device

Technical field

The utility model relates to power field, specifically is a kind of electricity generating device of using the lever force-saving principle.

Background technique

Generating is meant the production process of utilizing generation power device heat energy, nuclear energy and the solar energy of water energy, fossil fuel (coal, oil, rock gas), wind energy, geothermal power, ocean energy etc. to be converted to electric energy.Need in order to supply national economy all departments and people's lives.Generation power device is divided into thermoelectricity power loading amount, water power power plant, nuclear voltaic power apparatus and other energy generation power devices by the kind of the energy.The thermoelectricity power plant are made up of boiler of power plant, steam turbine and generator (being used to claim three big main frames) and auxiliary device thereof.The water power power plant are made up of hydraulic generator unit, speed regulator, oil gear and other auxiliary devices.The nuclear voltaic power apparatus is made up of nuclear reactor, steam generator, Turbo-generator Set and other accessorys.

Up to the present, main forms of electricity generation is thermal power generation, hydroelectric power and nuclear energy power generation, and three's generated energy accounts for more than 99% of whole generated energy.Thermal power generation is because of being subjected to the influence of coal, oil, natural gas resource and environmental pollution, and with regard to worldwide, proportion is about 64%; Hydroelectric power is nearly 90% because of the water resources development of industrially developed country, so proportion maintains about 20%, but the restriction that the place is subjected to the geographical position is set, and therefore, must realize powering on a large scale by long distance power transmission, correspondingly has the electric energy loss problem; The proportion of nuclear energy power generation is then in rising trend, surpasses 15%.

Except above-mentioned three kinds of main forms of electricity generation, common forms of electricity generation also comprises: diesel generation and wind-power electricity generation; Diesel generation is to be fuel with diesel oil etc., is that prime mover drives generator for electricity generation with the diesel engine.The diesel generating set of realizing diesel generation belongs to discontinuous operation power generating equipment, if operation surpasses 12h continuously, its output power will reduce about 10%.Although the power of diesel generating set is lower, but because its volume is little, flexible, light, comprehensive, be convenient to operation and maintenance, so be widely used in departments such as mine, railway, open-air building site, road traffic maintenance and factory, enterprise, hospital, as standby power supply or interim power supply.This small-sized generator set also can be used as small-sized mobile power station use simultaneously, and the back-up power that becomes a lot of enterprises uses.Owing to be to be fuel, equally there is problem of environment pollution caused with thermal power generation with diesel oil etc.

Wind-power electricity generation is to utilize wind-force to drive the air vane rotation, sees through the speed lifting of booster engine with rotation again, impels generator for electricity generation.According to present windmill technology, approximately be the gentle breeze speed (degree of gentle breeze) of three meters of per seconds, just can begin generating.The wind-power electricity generation utilization be natural energy resources, do not have fuel problem, can not produce radiation or atmospheric pollution yet.What diesel generation will be good relatively is many.But if answer emergency to use, still not as diesel generator.Wind-power electricity generation is very popular in countries such as Finland, Denmark; China also advocates energetically in the west area.But,, must again to the storage battery charging, make the electric energy of wind-driven generator generation become chemical energy through the charger rectification so its output is the Ac that changes because the output of wind-driven generator is subjected to that air quantity is unsettled to be influenced.With the inverter that protective circuit is arranged, the chemical energy in the storage battery is transformed into the alternating current 220V civil power then, could guarantees stable the use, cost is higher.
