          后备保护器  Backup protector




          使用范围  Scope of use

          ◆ 对通过的工频电流和雷电流实现选择性分断，能有效保护 SPD 因异常暂态过电压时，SPD 发生熔穿短路，造成严重火灾事故。
          ◆ 对通过的工频电流和雷电实现选择性分断，能有效保护 SPD 因发生劣化致使 SPD 启动电压降到低于电源电压工频漏电流增大，造成严重火灾事故。
          ◆ 当 SPD 有雷电流通过时，这个外置装置不会出现误脱扣，使电气设备防雷始终处于有效状态。
          ◆ Selective disconnection of the passed power frequency current and lightning current can effectively protect the SPD from melting and short-circuiting due to
           abnormal transient over-voltage, resulting in serious fire accidents.
          ◆ Selective breaking of the passed power frequency current and lightning can effectively protect the SPD from causing the SPD starting voltage to drop below the
           power supply voltage and increase the power leakage current, resulting in a serious fire accident.
          ◆ When the SPD has lightning current, the external device will not be accidentally tripped, so that the lightning protection of the electrical equipment is always in the
           effective state.
