Description
Technical field
The utility model relates to a kind of aviation ground power supply system.
Background technology
Modern airline carriers of passengers mostly with 400HZ, 115/200V AC power and 28.5V DC power supply as the standard power supply.The Alternating Current Power Supply of 400HZ mainly is used in large-scale, medium-sized passenger plane, and direct current 28.5V power supply then is mainly used in baby plane and military aircraft.The related power supply of this paper is mainly 400HZ midfrequent ac power supply.Because power supply with frequency can be divided into power frequency (50HZ, 60HZ), intermediate frequency (400HZ), (800HZ 1000HZ), so the 400Hz power supply is claimed intermediate frequency power supply again, mainly is used in aviation field to high frequency electric source.
" supply vehicle " refers to come the externally system of power supply with the fuel oil machine as power drive 400Hz or 28V DC generator, i.e. the ground power supply system of power engine driving.Used supply vehicle is such structure now.The supply vehicle of Civil Aviation System great majority are intermediate frequency 400HZ supply vehicle at home; Have few part to be friendship, straight type, pure DC power supply car uses more Civil Aviation System few employing the to the utmost at military aircraft." the power supply object " of " supply vehicle " for before airport ground and airline machine level ground, hangar are flown boat, the boat back is checked and aircraft or other intermediate frequency power consumption equipment of ground maintenance period.400HZ power supply when mainly solving aircraft and stopping on ground, in most of the cases aircraft also can be supplied power by own electricity generation system (APU) itself on ground, but APU system cost of electricity-generating exists the bigger problem of toxic emission again than higher.Land according to civil aviaton's regulation aircraft and should supply power by ground installation in principle after getting into the seat in the plane.
Because early stage oily mechanomotive force and the maturation of generator techniques and the difficulty of airport distribution, supply vehicle become the unique selection of aircraft floor power supply.Last century the seventies along with the development and the maturation of inversion transformation technique, the 400HZ inverter appears.This conversion is that 50HZ or 60HZ mains supply are carried out rectification, adopts direct current the high power switch element to be reverse into the 400HZ AC power again.Owing to there is not the conversion between electric energy-mechanical energy, this power supply is called as inverter system, is called for short " quiet variable power source ".Raising along with the full-fledged of inversion transformation technique and high-power components performance in recent years makes quiet variable power source from convenience, reliability, the feature of environmental protection, economy aspects very big improvement arranged; More make its high efficiency, high reliability and low noise, non-exhaust emission make it replace supply vehicle in many occasions.But the deficiency that the electrical network support must be arranged can't be competed it with supply vehicle aspect application flexibility.
Present airport ground power supply power supply should be the scene that inverter system and supply vehicle have half share.At energy-saving and cost-reducing and protection environment is today of social pay attention to day by day day by day, but because the advantage of mobility, flexibility, we also can't replace the conventional power source car that drives with oily machine; Also have to stand big decibel noise, waste gas and the fallback of supply vehicle.
