Abstract
The invention concerns an auxiliary power unit using compressed air for energy and equipped with a motor alternator driving, or being driven by a motor compressor with compressed air which compresses air under high pressure in a high pressure storage tank and which when there is a power cut automatically drives the motor compressor in alternating mode to supply electricity. The invention is applicable to fixed or mobile auxiliary power units.
Claims12
Back-up generator set operating on reserves of compressed air, characterized in that the compressed-air motor is reversible and operates either in compressed-air motor mode or in compressed-air compressor mode—compressed-air motor-compressor (5)—driven by, or driving, an electric motor which is also reversible which can act as a generator—motor-generator (1)—in which, during operation, the motor-generator in electric motor mode which receives its energy from an electricity network, runs, driving the compressed-air motor-compressor, operating in compressor mode, which fills one or more high-pressure compressed-air reservoirs and keeps them full and in which, when there is a break in the electrical power supply, the motor-compressor is automatically switched to motor mode and powered with energy by the compressed air contained in the storage reservoir or reservoirs (6) and drives the motor-generator which has also automatically been switched into generator mode to provide back-up electrical power.
