Storage battery fusing protective device provided with state monitoring indication lamps

A storage battery fusing protective device provided with state monitoring indication lamps comprises two protective structures respectively applied for connecting the anode and the cathode of a storage battery. Each protective structure comprises a fuse and a fusing signaling device. The two electrodes of the fusing signaling device are correspondingly connected with the two electrodes of the fuse. The fusing signaling device has a microswitch. When the protective device is in use, the microswitch is serially connected with a signal relay before being accessed to a direct current system. When the fuse is broken, the microswitch is then closed. Each indication lamp is serially connected with a current limiting resistor and then connected on the two ends of the microswitch of the fusing signaling device in a parallel way. When the microswitch is broken, the voltage loaded on the two ends of the signal relay is smaller than the starting voltage of the signal relay. The state monitoring indication lamps are arran
