MULTI-VOLTAGE POWER AUTOTRANSFORMER FOR THE HIGH-VOLTAGE ELECTRICITY TRANSMISSION NETWORK-(POLYTRANSFORMER)

摘要

A multi-voltage power autotransformer for the high-voltage electricity transmission network, Polytransformer, has a compact design and has different selectable voltage levels at the input and/or output, supplying different transformation ratios, being able to be used to interconnect high-voltage electrical systems in multiple transformation stations. It is a suitable solution as a contingency plan for emergencies in substations which need this, and can be configured to different input and/or output voltage levels and connected to different electrical power transmission systems in the high-voltage network, which, due to fault or another necessity, require it. The multi-voltage autotransformer is a power transformer with design characteristics which optimize the combination of possibilities of different input and/or output voltage values and maximum power with the rail transport limitations.
