防逆流光伏并网箱是将防逆流保护装置、光伏并网断路器、浪涌保护器、光伏隔离刀开关、电流互感器等设备安装于一个箱体内，用于光伏并网发电系统中，确保光伏系统安全和稳定运行的同时防止光伏并网系统逆向发电。

The reverse-flow protection PV grid-connected enclosure integrates components such as a reverse-flow protection device, a PV grid-connected circuit breaker, a surge protector, a PV isolation knife switch, and a current transformer within a single enclosure; it is designed for PV grid-connected power generation systems to ensure the safe and stable operation of the PV system while preventing reverse power generation in the PV grid-connected system.
