<P>PROBLEM TO BE SOLVED: To provide a distribution board with which the number of components can be reduced more than before and a voltage adjustment device unit can be inspected, repaired and added without stopping the entire distribution board. <P>SOLUTION: A distribution board 5 is configured by incorporating, inside one rack 9, a plurality of voltage adjustment device units 1 including a reference data preservation part 22 for preserving various kinds of reference data for control including the reference data for voltage control and a tap switching command generation part for generating a tap switching command for switching a tap of a tap switching three-phase transformer 7 on the basis of the reference data for the voltage control and the output voltage of the tap switching three-phase transformer 7. The voltage adjustment device unit 1 does not include a data setting device for setting the reference data for the control to be preserved in the reference data preservation part 22, and includes a data write part 21 for, when the reference data for the control set on the outside is received, writing the received reference data for the control to the reference data preservation part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
