交换机电源模块是用在交换机里面为交换机提供稳定电压以供给设备正常启动的电源模块。是市面上比较常用的电源模组。本文介绍一款交换机电源（电源供电电压为DC35-DC70V）全模防护方案。该方案采用三极防护，具有钳位电压低，防护等级高的优点。满足IEC61000-4-5浪涌测试标准，可过差模5KA，共模5KA。该方案在产品中的防护电路图和实际应用图片如下：

图1、防护电路图

图2、实物图

该方案运用到的防护器件是硕凯电子的压敏电阻 20D101KJ和陶瓷气体放电管SC2E8-150LL。

20D101K的压敏电压为100V，考虑是用在宽压DC35-DC70V，能满足正常电压选型压敏电压标准。通流量为10KA，拥有足够的余量，能够满足5KA的测试标准；SC2E8-150ML选用的击穿电压为150V，与压敏的电压相接近，满足正常工作电压选型标准，通流量也达到10KA的水平，满足浪涌5KA测试标准。

总结：选择足够通流量的压敏电阻做前级保护，保证先对浪涌进行大部分吸收与泄放。后级用中小功率TVS进行精确防护，让残压足够低，就可满足高等级浪涌需求。

硕凯陶瓷气体放电管SC2E5-150LL在电流互感器二次侧过压防护的应用

采用陶瓷气体放电管作为电流互感器二次侧过电压保护器的电压采样器件,其优越性在实际的应用中已经得到验证。在实际的应用中,使用了陶瓷气体放电管的电流互感器二次侧过电压保护器能够有效地减少漏电空开跳闸和产品自身发热烧毁现象,对于电流互感器一次侧经常会出现的一些瞬态的电压尖峰现象,也能够有效的滤除,不会出现经常误动作的现象。

【应用】国产压敏电阻14D561K用于LED路灯，通流量可达6KA

由于LED灯具有节能、响应时间短、使用寿命长、可直接替换传统灯等优点，所以LED灯的应用越来越广泛，现如今LED路灯也是随处可见。本篇主要讲述硕凯电子14D561K压敏电阻在LED路灯的应用，具有大通流量雷电在电源线路上产生感应浪涌，这个浪涌的能量会在电线上产生一个突波，即浪涌波，浪涌就是通过这样的感应方式进行传输的。

【经验】压敏电阻防雷的工作原理及特点

压敏电阻器相当于一个可变电阻，它是并联于电路中的，当电力线被雷击时，雷电波的高电压使压敏电阻击穿，雷电流通过压敏电阻流入大地，使电力线上的电压被钳制在安全范围内。压敏电阻的性能稳定、通流能力大，由于其突波承受能力取决于它的物理尺寸，因而有可能获得不同的浪涌电流值。
