          安装  Installation

                                                                                                     2
          ◆ 产品安装在 LPZ0A 或 PLZ0B 与 PLZ1 区交界处，或在电源引入的总配电箱（柜）处采用 35mm 标准导轨安装。连接导轨采用 6-35mm 多股铜制软线。
                         2
          ◆ 接地线应采用 16mm 以上的双色导线，长度不大于 500mm。
          ◆ 为了防止电涡保护器失效后影响电网运行安全，联接于睦毫的保护嚣应串联一个配套的 HDSCB 后备保护器。
          ◆ The product is installed at the junction of LPZ0A or PLZ0B and PLZ1 area, or installed on the 35mm standard rail at the main distribution box (cabinet) of the
                                            2
           power supply. The connecting rail adopts a 6-35mm  multi-strand copper cord.
                                              2
          ◆ The grounding wire should be a two-color wire of 16mm  or more, and the length is not more than 500mm.
          ◆ In order to prevent the safety of the grid from being affected after the failure of the eddy current protector, a protective HDSCB backup protector should be
           connected in series with the protection.


          主要结构及工作原理  Main structure and working principle

          ◆ SPD 为 - 端口，防触电保护，户内式固定安装，电压限制型。
          ◆ 具有冲击电流大（limp:1 5kA）．残压低（Up：≤ 1.5kV）等特点。
          ◆ SPD 内置脱离器。当 SPD 因过热击穿失效时，脱离器能自动将其从电网上脱离．同时给出指示信号。正常工作时可视窗口显示白色，失效脱离后显示红色。
          ◆ SPD is - port, anti-shock protection, indoor fixed installation, voltage limited type.
          ◆ With large inrush current (limp: 15kA). Low residual pressure (Up: ≤ 1.5kV) and other characteristics.
          ◆ SPD built-in disconnector. When the SPD fails due to overheating breakdown, the disconnector can automatically detach it from the grid. An indication signal is
           also given. The visible window displays white when it is working, and it turns red when it fails.
