分を示す。FIG. 1 is a single line diagram of a conventional device, FIG. 2 is a front view showing the configuration of FIG. 1, and FIG. 3 is a plan view of FIG. 2, showing only one phase. Fig. 4 is a single line diagram showing an embodiment of this invention, Fig. 5 is a front view showing the configuration of Fig. 4, and Fig. 6 is a diagram showing the configuration of Fig. 5.
In the plan view of the figure, only one phase is shown. In the figure, 1.5 is a bushing, 2.4 is a current transformer, and 3
is a tank-type gas breaker, 6 is a lightning arrester, and 7 is a branch busbar. Note that the same reference numerals in each song indicate the same or corresponding parts.
