high voltage and high voltage electricity transmission network autotransformer for

摘要

The high-voltage electricity transmission network, multi-for-voltage power autotransformer, that is, poly-transformer, has a compact design, had have a type and / or different selectable voltage levels to the phase output, and provides a different transformation ratio, and in a number of transform points it may be used to interconnect the electrical system voltage. ; It is a solution suitable as a measure in an emergency due to a failure or other need in the substation, to each other can be formed on the other input and / or output voltage level, and - allows to connect the different electric power transmission system in voltage network . ; The multi-voltage autotransformer is a power transformer with design characteristics which optimize the possible combinations of the transport track satisfies the limits and at the same time with different input and / or output voltage values ​​and maximum power.
