めである。 DESCRIPTION OF THE PREFERRED EMBODIMENTS The main parts of a closed switchboard according to an embodiment of the present invention will be explained below with reference to the drawings. In FIGS. 6 and 7, 13 is an insulating member made of, for example, epoxy resin, and has a through hole 13a bored inside. Reference numeral 14 denotes a metal pipe that passes through this through hole 13a and is integrally formed with the insulating member 13.The power supply side conductor 5 passes through this metal pipe 14 and is attached to the metal pipe by bolts or the like through the provided fixing hole 14a. It is electrically and mechanically connected and fixed to 14. In this way, since the insulating member 13 and the metal pipe 14 are integrally molded, both members 1
Since there is no space gap between 3 and 14, no corona discharge occurs. Furthermore, FIG. 8 is a side sectional view showing a schematic configuration of a closed switchboard to which this embodiment is applied, and as is clear from the figure, the insulator supporting the power supply side conductor 5 has been changed from the conventional one in FIG. 7
is omitted, but this is because the power supply side conductor 5 is fixed to the metal pipe 14 as described above.
