ZRCT P255 弧光保护装置ZRCT P255 Arc Protection Device

ZRCT P255弧光保护系统主要适用于35kV以下电压等级的母线和开关设备保护。该弧光保护主要用于开关柜内中低压母线保护馈线电缆连接头保护、箱式变电站保护、整流柜保护；该弧光保护装置采用特殊的弧光检测和电流检测双判据原理、保护动作速度快、可靠性高，是非常灵敏的弧光保护系统。通过在开关设备使用弧光保护装置，一旦发生弧光故障使用伤害和危险降到小。

ZRCT P255 arc protection system is mainly applicable to bus and switch equipment protection under 35kV voltage level. The arc protection is mainly used to protect the middle and low voltage busbar in the switchgear cabinet, the feeder cable connector protection, the box substation protection, the rectifier cabinet protection; The arc protection device adopts the principle of special double criterion of arc light detection and current detection, the protection has fast speed and high reliability, which is a very sensitive arc protection system. By using arc protection device in switchgear, the damage and danger in case of arc failure can be minimized.
