PURPOSE:To obtain the titled transformer with a lifting gear having excellent workability without increasing a floor space by mounting a chain block, which can travel, for lifting a switch to a conservator arranged to the upper section of an on-load tap changer. CONSTITUTION:A chain block travelling rail 12 is installed to the side surface of a conservator 4 so that the center is positioned just above on-load tap changers 2, a travelling chain block 13 is mounted to the chain block travelling rail 12, and stoppers 14 are fixed at both end sections of the chain block travelling rail 12 so that the travelling chain block 13 is not slipped off. When a switch 7 is lifted, a cover for the on-load tap changer 2 is removed, the travelling chain block 13 is shifted just above the arbitrary on-load tap changer 2, the switch 7 is hoisted up to proper height by the travelling chain block 13, the travelling chain block 13 is moved horizontally up to the position of suspension, and the switch is hung down by the travelling chain block 13 up to a floor surface. |
