PURPOSE:To flow a DC returning current to the cases of line buses safely, by providing a current conductor along the outside of a tank between two cases for the line buses. CONSTITUTION:Insulating pipes 31 are provided between one lead part 14 of the tank 12 wherein a reactor main body 13 is incorporated and the case of one line bus 17 and between the other lead part 15 of the tank 12 and the case of the other line bus 18 which is connected to the lead part 15. Thus the part between both elements are electrically insulated. A connecting conductor 34 which forms a bypass of the returning current is attached to the outside of the tank 12 between the cases for the buses 17 and 18. In this constitution, since the part between the cases of the buses 17 and 18 is connected by the bypass conductor 34, the tank 12 is not heated, and the returning current Ir can be safely conducted. |
