荷２への電流がしや断される等の欠点があつた。 Conventionally, the circuit of this type of DC power distribution device is shown in FIG. are connected via. In this circuit, for example, if a short circuit occurs on the load 2 side (No. 1), the short circuit current flowing from the DC power supply 1 side will blow the fuse 3 on the load 2 side (No. 1) and switch the DC switch. No. 4 and 4 may occur at the same time, resulting in short circuits and, for example, the current to (No. 2) load 2 may be interrupted.
本考案は上記欠点を除去するもので、一実施例

閉器４をしや断させないようになつている。 As shown in Figure 2, fuse 3 and DC power supply 1 are connected in parallel on the load 2 side of (No. 1) and (No. 2).
A DC power distribution device consisting of a reactor 5 connected in series with one DC switch 4 connected in series on the side, and an electrolytic capacitor 6 connected in parallel. DC power is divided from (No. 1) and (No. 2) and supplied to the loads 2, but at this time the electrolytic capacitor 6 is charged to the power supply voltage. If a short circuit occurs on the load 2 side (No. 1) of the fuses 3 connected in parallel, the short circuit current flowing from the DC power supply 1 side is momentarily suppressed by the reactor 5, and the short circuit is suppressed by the discharge of the electrolytic capacitor 6. By supplying current, only the fuse 3 on the load 2 side (No. 1) is blown, and the DC switch 4 on the DC power supply 1 side is not blown.
従つて、短絡が発生しない（No.２）の負荷２へ
は直流電源１から負荷電流が常に流れることにな
る。 Therefore, the load current always flows from the DC power supply 1 to the load 2 where no short circuit occurs (No. 2).

る。 As described above, in a DC distribution circuit, when a short circuit occurs on the load side due to fuses connected in parallel, the present invention prevents the short circuit from occurring without breaking one DC switch connected to the DC power supply side. This is of great practical value, as DC power can be continued to be supplied to load circuits that are not short-circuited by blowing only the fuses of the load circuits that have been short-circuited, improving the reliability of the device.
