季先生 18913211514 0512-87889806 qq：3039800056供电系统的电涌保护 第一级电涌保护 火花间隙 工作状态检测、维护和认证pu 1 tsg + 和pu 1 tsg提供一个状态指示灯以便于维护人员了解其是否处于正常工作状态。当状态指示灯熄灭时，表示主回路失电或电子触发部件故障。建议在雷雨天气期间经常去检查一下指示灯的状态。 使用电子触发式电源保护器可以得到很大的放电电流，而且过压保护等级＜1.5kv。在pu 1 tsg+和pu 1 tsg电涌保护器之前需安装备用熔丝，熔丝大小通常根据导线的截面积来决定安装于pu 1 tsg+前端的备用熔丝最大值为250a gl，安装于pu 1 tsg前端的备用熔丝最大值为125a gl。使用火花间隙的电涌保护器用于第一级保护（b级保护） 按照b级（din vde 0675 part 6(draft 11.89)a1:3/96）和第一级（iec 61643-1（1/02））的要求，从区域0到区域1（iec 1312-1）的防雷击保护使用火花式电涌保护器。通过几个电涌保护器的不同组合可以对tn,tt和it电网系统进行电涌保护。 当雷击时，电子触发式火花间隙电涌保护器在电源系统和建筑物等电位接地带之间提供了一个必需的连接。 电涌保护器连接导线截面硬导线： 10…35mm2,多股硬导线 10…25mm2,工作温度范围 ﹣40℃…﹢85℃.pu 1 tsg电涌保护器具有ul和kema认证，可在全球范围内使用。组合式电涌保护器 组合式电涌保护器，直接对最终的设备和部件提供保护。 combi pu i+ii由第一级的电子触发式火花间隙电涌保护器pu 1 tsg和第二级的pu c压敏电阻电涌保护器以及相应的横联件组合而成。组合式电涌保护器使过压保护等级低的电气和电子设备免受雷电和线路中电涌电压的冲击。 combi pu i+ii组合式电涌保护器符合iec 61643-1（feb 1998）标准的要求。pu r i+ii combi可提供一个转换触点输出电涌保护器状态信号。 电气安装 combi pu i+ii组合式电涌保护器到相线盒零线和用户接地点的导线越短越好。为保护的导向（比如电表进线）和被保护的导线不可以一起布线。 combi pu i+ii组合式电涌保护器既可以用于4线电网系统（相线经过三个电涌保护器模块pen线相联），也可以用在5线电网系统（相线经过三个电涌保护器模块通过n-pe电涌保护器同地线相联）。 按照iec 947-7-1标准，可以连接各类导线的截面积如下：单股线 10…35mm2多股硬导线 10…25mm2多股软导线 10…25mm2工作温度范围﹣40℃…﹢60℃1351120000 vpu ii 4 750v/25ka1351130000 vpu ii 4 r 750v/25ka1351140000 vpu ii 3+1 750v/25ka1351150000 vpu ii 3+1 r 750v/25ka1351090000 vpu ii 3
