The invention relates to a new energy automobile power battery direct-current high-voltage anti-inverter-circuit-reverse-current protection tube, which comprises a protection tube body, wherein the protection tube body comprises a connecting copper sheet I, a connecting copper sheet II, a shell, a copper fuse wire and an anti-inverter-circuit-reverse-current diode, one end of the copper fuse wire is connected with one end of the anti-inverter-circuit-reverse-current diode, the other end of the copper fuse wire is connected with the connecting copper sheet I, the other end of the anti-inverter-circuit-reverse-current diode is connected with the connecting copper sheet II, and the copper fuse wire and the anti-inverter-circuit-reverse-current diode are respectively arranged in the shell. According to the invention, during use, the protection tube body is installed on a power battery bus cable, and a battery is connected with electrical equipment through the protection tube body; and the high voltage of a power battery can generate an electric arc when a copper fuse wire is fused, and the electric arc is stopped by an anti-inverter-circuit-reverse-current diode, so that the problems that a power battery control system, a current sensor, a collector precision device and the like are damaged due to the electric arc and the like are prevented.
本发明涉及一种新能源汽车动力电池直流高压防逆电反流保险管,包括保险管本体,保险管本体包括连接铜片Ⅰ、连接铜片Ⅱ、外壳、铜熔断丝和防逆电反流二极管,铜熔断丝一端与防逆电反流二极管一端连接,铜熔断丝另一端与连接铜片Ⅰ连接,防逆电反流二极管另一端与连接铜片Ⅱ连接,铜熔断丝和防逆电反流二极管分别设置于外壳内;使用时,将保险管本体安装于动力电池母线电缆上,电池通过保险管本体与电器设备连接。动力电池的高电压在铜熔断丝熔断会产生电弧,通过防逆电反流二极管将电弧阻止,防止了因电弧导致动力电池控制系统、电流感应器、采集器精密器件等损坏等问题。
