あるなどの問題点があった。[Problems to be Solved by the Invention] As described above, in conventional power receiving and distribution equipment, the main body of the transformer is fitted into the opening of the cable shaft, so it is necessary to determine the dimensions of the cable shaft based on the power capacity. Since it was planned to be able to install a large number of objects, it had the disadvantage of being large. Another problem was that when the capacity was small, it was necessary to cover the opening with a cover or the like.

In the figure, 1 to 5 are the same as those in FIG. 3, and 5b is an opening large enough for the bushing of the transformer to fit into. Bushings 12 of transformers 6a and 6b having different power capacities are fitted into each opening. , the outer box 11 is installed against the wall 5. The high voltage trunk cable 3 is then connected to a cable connection portion 9 attached to the bushing 12. Note that 6b is a transformer having a larger power capacity than 6a, and can respond to changes in external dimensions.

In order to supply power to each floor in the building 1, power is received by the power receiving equipment 2, and the high voltage power is supplied to the transformers 6a and 6b via the high voltage trunk cable 3, and the transformers 6a and 6b then distribute the stepped down low voltage power to each floor. do. Note that the electric circuit of the transformer is the same as the conventional example shown in FIG. Since the bushing 12 is passed through the wall opening 5b of the cable shaft 4 and the outer box 11 is installed outside the cable shaft, even if the power capacity of each floor is different,
, 6b may have appropriate external dimensions. Further, since the outer box 11 of the transformer is installed against the wall surface of the cable shaft, the outer box covers the opening of the cable shaft and exhibits the effect of a cover.
