The above-described conventional tap changer device has the following problems. (1) Of the components in the tap changer device, the operating mechanism 3, the first direction changing device 42, the conservator 5
Is mounted on the wall and top plate of the transformer tank 1 via the respective mounting brackets, so it is difficult to secure the dimensional accuracy between the connecting elements including the connecting shaft and the oil pipeline, and it takes a long time to assemble and adjust. I was (2) Since the transformer tank 1 is a thin plate container, the tank is apt to be deformed, and the operation box 3, the first direction changing device 42, the tap changer 2, and the conservator 5 which have been once assembled are attached. In addition, a shape error such as parallelism is likely to occur, so that the fitting portion of the connecting shaft becomes unstable or oil leaks from a fastening portion of the oil pipeline. (3) For this reason, in the first direction changing device 42 and the tap changer 2, for example, a free joint and a free joint are provided at both ends of each connecting shaft so that a driving force can be obtained even if a slight error occurs in the mounting position. Relatively expensive measures were taken using parts such as telescopic joints. (4) In the case of a high-voltage large-capacity transformer in which the size of the transformer tank 1 is large, there is no particular problem. However, in the case of a low-voltage small-capacity transformer in which the size of the transformer tank 1 is relatively small, the transformer tank is used. Of the first direction changing device 4 is limited.
2 mounting bracket B10 and conservator 5 mounting bracket C11
Installation space could not be secured. (5) Further, since the second direction changing device 21d is mounted on the head cover 21c of the tap changer 2, the head cover 21d is maintained at the time of maintenance and inspection of the tap changer.
In the case of opening c, it is necessary to disassemble the horizontal connecting shaft 43, which deteriorates workability at the time of maintenance and inspection. (6) Further, since the transformer main body tank and the tap changer tank are integrated, the tap changer can be assembled only after the completion of the assembly of the transformer main body side, and the total time of the transformer assembling can be reduced. I couldn't shorten it.

Since 1h is provided, an error is hardly generated in each mounting position, and assembly and adjustment of the connection shafts 41 and 43 and the oil pipeline 6 are simplified. Furthermore, since the assembly of the tap changer 2 can proceed independently of the transformer assembling process, the total transformer assembling time can be reduced. Further, even if the tank is deformed, there is no influence on the mounting position of the first direction changing device 42 and the conservator 5, so that the fitting portions of the connecting shafts 41 and 43 are stabilized, and the oil pipeline 6 and the oil flow protection are protected. Oil leakage from the fastening portion of the relay 7 does not occur. In the horizontal connection shaft 43, the fitting portion of the shaft for transmitting the driving force is stable, and it is not necessary to use an expensive dedicated joint. Further, even in a low-voltage small-capacity transformer in which the width dimension of the transformer tank 1 is relatively small, the width dimension is not limited, and even if the width dimension is small, the first direction changing device 42 and the conservator 5 Mounting space for each mounting bracket can be secured.
