          电涌保护器  Surge protector device




          安装  Installation

                                                                                      2
          ◆ 安装在 LPZ0B 或 LPZ1 区与 LPZ2 区交界处，采用 35mm 的标准导轨安装，连接铜质多股导线为 2.5 ～ 35mm 。
          ◆ SPD 每极必须设置保护一一使用熔断器或小型断路器雷电流 SPD 保护，用于 SPD 击穿后短路保护。
          ◆ 安装在楼层配电箱、计算机中心、电信机房、电梯控制室、有线电视机房、消防中心、别墅、小区住户配电箱等。
          ◆ Installed at the junction of LPZ0B or LPZ1 area and LPZ2 area, it is installed with 35mm standard rails, and the copper multi-strand wire is 2.5~35mm².
          ◆ SPD must be set to protect each pole. Use fuse or small circuit breaker lightning current SPD protection for short circuit protection after SPD breakdown.
          ◆ Installed in the floor distribution box, computer center, telecommunications room, elevator control room, cable TV room, fire center, villa, residential household
           distribution box, etc.


          主要结构及工作原理  Main structure and working principle
          ◆ SPD 为一端口，防触电保护，户内式固定安装，电压限制型。
          ◆ SPD 内置脱离器。当 SPD 因过热、击穿失效时．脱离器能自动的将其从电网上脱离，同时给出指示信号。SPD 正常工作时可视窗品显示绿色，失效脱
           离后显示红色。
          ◆ 1P+N．2P+N．3P+N 的 SPD 由 1P、2P、3P 的 SPD+NPE 零地保护模块组成，应用于 TT、TN-S 等供电系统。
          ◆ SPD is a port, anti-shock protection, indoor fixed installation, voltage limited type.
          ◆ SPD built-in disconnector. When the SPD fails due to overheating and breakdown. The disconnector automatically detaches it from the grid and gives an
           indication signal. When the SPD is working normally, the window product displays white, and when it fails, it displays red.
          ◆ 1P+N. 2P+N. The SPD of 3P+N consists of SPD+NPE zero-ground protection modules of 1P, 2P and 3P, and is applied to power supply systems such as TT
           and TN-S.
