          电涌保护器  Surge protector device




          安装  Installation

          ◆ 本产品为一端口户内式固定安装电压开关型 SPD，产品依据 GB50057 和 GB/T18802.1 等现行国家标准而设计的；具有冲击电流大 (limp：25KA)、
           低残压 (Up:2.5KV) 等优点，其核心器件由多级石墨间隙组成，合理的设计、精确的加工将火花间隙组合在一起形成密封的结构保证了火花间隙内部的
           安全距离，即使在浪涌电流通过时，也不会产生电弧外泄安装时不必专门预留外泄电弧的空间。质量稳定可靠。
                                                                                                          2
          ◆ 产品安装在 LPZOA 或 LPZ0B 与 LPZ1 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 的多股
           铜质软线。
                         2
          ◆ 接地线应采用 16mm 以上的双色导线，长度不大 500mm。
          ◆ 为了防止电涌保护器失效后影响电网正常运行，联接于 L 线的保护器应串接一个熔断器或断路器（注：依据标称电流 In 选择）
          ◆ This product is a one-port indoor fixed voltage switch type SPD. The product is designed according to the current national standards such as GB50057 and GB/
           T18802.1; it has large inrush current (limp: 25KA) and low residual pressure (Up :2.5KV), the core device is composed of multi-stage graphite gap. Reasonable
           design and precise machining combine the spark gap to form a sealed structure to ensure the safety distance inside the spark gap even when the inrush current
           passes. There is also no space for the arc leakage to be installed without having to reserve a leakage arc. The quality is stable and reliable.
          ◆ The product is installed at the junction of LPZOA or LPZ0B and LPZ1 area, or at the main distribution box (cabinet) where the power is introduced, and is installed
                                                   2
           with 35mm standard rail. 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 Surge protector device from affecting the normal operation of the power grid, the protector connected to the L line should be connected in
           series with a fuse or circuit breaker (Note: according to the nominal current In)
