Abstract
PURPOSE: To enable tap changer control with high reliability, in parallel operation of a on-load tap change-over transformer, by providing a parallel tap position detecting circuit and an idle tap location detecting circuit.
CONSTITUTION: Control power supply buses P1, N1 are connected to DC control power supply buses P, N via a power supply switch 11, and the common tap CB of a dial switch 7 at a load tap changer LTC10 is connected to one power supply bus P1 via a contact 12a. Further, terminals 1CW11C of the terminal board 13 provided with a distribution panel 9 are connected to taps 1BW11B of a dial switch 7 through a multicore cable. One end of an idle tap position detecting relay 15 is connected to terminals 3C, 5C, 7C and 9C, and another end is to the power supply bus N1. One of a parallel tap position detecting relay 16 is connected to terminals other than mentioned above and another is to the power supply bus N1 respectively. Thus, reliable tap change-over control can be made.
