PURPOSE:To obtain the compact on-load tap changing transformer which can be readily maintained by attaching a breaking part and a current limiting resistor for at least one phase to different insulated supports in the same plane, providing fixed conductors in said supports, and connecting these conductors by a jumping conductor which can be freely attached or detached. CONSTITUTION:The on-load tap changing transforer 12 is constituted by connecting a switch 7 having a quick disconnect mechanism 13 at the top and a tap selector 8 having an intermittent sending mechanism 15 at the top by a linking part 14. Said assembly is enclosed in a transformer tank 11. The switch 7 is constituted by an oil container 19 comprising a mechanism box 16, an insulating tube 17, and a bottom plate 18. The breaking parts 9U, 9V, and 9W and the current limiting resistors 10U, 10V, and 10W for three phases are enclosed in the container 19. In this constitution, the breaking part and the resistor for one phase are attached to the separate insulated supports 20A and 20B. The connection to fixed conductors 23A and 23B which are provided thereon is performed by the jumping conductor 24 which can be freely attached or detached. |
