A plurality of fuses (F1, F2,..., Fn) are respectively disposed on current paths of a plurality of currents shunted from one end of a DC power supply (10). In a fuse detection device (11), one ends of a plurality of capacitors (C1, C2,..., Cn) are connected to one ends of each of a plurality of fuses (F1, F2,..., Fn) on the downstream side. A plurality of currents flowing through a plurality of capacitors (C1, C2,..., Cn) are input to a circuit switch (30) and a circuit resistor (31). The microcomputer (37) instructs the circuit switch (30) to switch on, acquires a detection value of the resistance voltage, and detects, on the basis of the acquired detection value, whether or not there is a fused fuse among the fuses (F1, F2,..., Fn).
在从直流电源(10)的一端分流的多个电流的电流路径分别配置多个熔断器(F1、F2、…、Fn)。在熔断检测装置(11)中,在多个熔断器(F1、F2、…、Fn)各自的下游侧的一端连接多个电容器(C1、C2、…、Cn)的一端。经由多个电容器(C1、C2、…、Cn)流动的多个电流向电路开关(30)及电路电阻(31)输入。微机(37)指示电路开关(30)的向接通的切换,取得电阻电压的检测值,基于取得的检测值,来检测在熔断器(F1、F2、…、Fn)之中是否存在熔断的熔断器。
