The invention provides a fuse box, a vehicle-mounted protection system and a vehicle. The fuse box is provided with a first circuit and a second circuit; the first circuit comprises a plurality of first protection branches connected in parallel, each first protection branch is provided with a fuse module, and one end of each first protection branch is connected with a first power supply through a first power supply interface; the second circuit comprises a second power supply interface and a plurality of second protection branches which are connected in parallel, each second protection branch is provided with at least two fuse modules which are connected in series, one end of each second protection branch is connected with a second power supply through the second power supply interface, and when the second protection branch is short-circuited and fused, the fuse modules are connected in series. On the second protection branch, the arcing voltage for realizing arcing connection between the second power supply and the second electric appliance exceeds the output voltage of the second power supply; the output voltage of the first power supply is lower than the output voltage of the second power supply, so that the development cost of fuse boxes of different voltage systems in the vehicle can be reduced, and the development cost of the vehicle is further reduced.

    本文提供了一种保险丝盒、车载保护系统及车辆,保险丝盒设有第一电路和第二电路;第一电路包括多个并联连接的第一保护支路,第一保护支路上设有保险模块,第一保护支路的一端通过第一电源接口连接第一电源;第二电路包括第二电源接口和多个并联连接的第二保护支路,每个第二保护支路上设有串联连接的至少两个保险模块,第二保护支路的一端通过第二电源接口连接第二电源,当所述第二保护支路发生短路熔断时,该第二保护支路上第二电源和第二用电器实现拉弧连接的拉弧电压超过第二电源的输出电压;第一电源的输出电压低于第二电源的输出电压,本文可以降低车辆中不同电压系统保险丝盒的开发成本,进而降低了车辆的开发成本。
