いる。In addition, in order to use the power line F as a transmission path for high frequency waves such as communication waves, a blocking coil 2 consisting of a capacitor CB and a coil LB is connected in series with the power line F, so that it exhibits low impedance for commercial frequencies and low impedance for high frequencies. By providing high impedance, high frequency transmission characteristics are improved.
本発明の目的は、構成機器を効果的にまとめることによ

に位置した端を再度折り返さなければならない。The instrument transformer 1 is molded with resin or housed in an insulating cylinder, and a blocking coil 2 is mounted on the top of the instrument transformer 1, and the upper end of the instrument transformer 1 and the lower end of the coil are electrically connected. Mechanically connected and supported. A conductor 8 is led out from the connecting portion between the two, and this conductor 8 is housed in a connecting container 9 coupled to the side wall of the intermediate portion of the container 6. The upper end of the coil 2 is connected to a bus conductor by a conductor 10 housed in a connection container 11. Generally speaking, it is convenient for the overall construction to lead out a pair of connecting containers from above the container 6, but in this case the coil 2 has to be folded back again at its lower end.

ル２の径を小さくできる。At this time, consideration must be given to electrical insulation of the folded portion, which increases the diameter of the coil 2 and, accordingly, the diameter of the container 6. On the other hand, if one end of the coil 2 is led out from the side wall of the container 6 as shown in FIG. can.

うようにしたため、小型の機器が得られる。Moreover, since this container 6 is connected to the lower part of the busbar side, there are almost no component devices near that side. Therefore,
Even if it is led out to the side like the container 9 and then raised to the required height, it does not affect the overall structure. The connection container 11 may be formed on the side wall of the container 6 as long as it is located above the container 6. When connecting to a bus conductor in the air, this is done by bushing. As described above, the present invention
Since the configuration is simplified by skillfully combining the components, and the coil 2 is led out at the upper end and side wall, a compact device can be obtained.
