The invention relates to a fuse, a battery high-voltage system and a vehicle, the fuse comprises a first trigger loop and a second trigger loop, the first trigger loop comprises a driving module and a first igniter, the first trigger loop and the second trigger loop are connected in parallel, and the first trigger loop and the second trigger loop share the first igniter; a non-return module is arranged between a first power supply end and a first igniter (or between a second power supply end and the first igniter) in a second trigger loop, when the second trigger loop is short-circuited, the second trigger loop loses efficacy, the first trigger loop is started, and the non-return module cuts off passing of first driving voltage; when the first trigger loop is triggered, current can only pass through the first igniter instead of passing through the non-return module and the short circuit point, so that the first igniter is triggered, the first trigger loop can be effectively triggered, and safety is improved.
本公开涉及熔断器、电池高压系统及车辆,该熔断器包括第一触发回路和第二触发回路,第一触发回路包括驱动模块和第一点火器,第一触发回路和第二触发回路并联,且第一触发回路和第二触发回路共用第一点火器,通过在第二触发回路中的第一供电端与第一点火器之间(或在第二供电端与第一点火器之间)设置逆止模块,在第二触发回路发生短路时,第二触发回路失效,启动第一触发回路,逆止模块截止第一驱动电压通过,电流不能通过逆止模块和短路点,只能通过第一点火器,从而第一点火器被触发,保证了第一触发回路能够被有效触发,提高了安全性。
