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。
2
◆ 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 2.5~35mm .
◆ 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

在三相四线制系统中，三条相线和一条零线对接地线之间均有保护器（见图 1）。在正常情况下保护器处于高电阻状态，当电网因雷击或者其它原因出现浪
涌过电压时．保护器在纳秒级时间内迅速导通，将浪涌过电压引入大地，从而保护了电网上的用电设备。当该浪涌电压通过保护器且消失后，保护器重新恢
复到高电阻状态，从而不影响电网的正常运行。
In a three-phase four-wire system, there are protectors between the three phase lines and one neutral line to the ground line (see Figure 1). Under normal
conditions, the protector is in a high resistance state when the grid is subjected to a surge overvoltage due to lightning strikes or other reasons. The protector
quickly turns on in the nanosecond time, introducing surge overvoltage into the earth, thus protecting the electrical equipment on the grid. When the surge voltage
passes through the protector and disappears, the protector returns to a high resistance state, thereby not affecting the normal operation of the power grid.
