【选型】硕凯电子联合电安科技，完美实现ACDC电源模块输入防雷器件国产化替换

时间： 2020-10-14 来源：世强

随着国产化需求逐渐提高，越来越多的产品开始采用国产器件。本文将结合硕凯电子和电安科技的防护产品，介绍在ACDC电源模块上防雷电路器件的国产化选型方案。

如图1所示，是一个典型的单相AC输入的防雷电路示意图，采用此电路的优势在于：采用复合对称电路，共模差模全保护；正常工作时无漏电流，可以延长器件使用寿命；火线零线随便接，安全；压敏电阻短路失效后，由于保险丝的存在，能与电路脱离，一般不会引起火灾。目前此方案多采用Littelfuse的保险丝加上EPCOS的压敏电阻和气体放电管方案，综合交期价格等因素考虑，需要一套全国产化替代方案。

针对以上需求，以输入AC220V，1KW ACDC电源模块为例，国产化选型推荐如下：

1、电安科技是专业保险丝研发生产厂家，其保险丝产品技术在国内处于领先水平。

针对1KW ACDC电源模块，考虑AC220V输入电压波动，参数需求10A 250VAC。推荐电安科技的CA421系列的CA421A010，电气参数10A/250VAC，满足电源模块参数需求。其产品属于快熔型，保护响应时间快；符合UL认证和RoHS环保认证，可靠性高；5*20小尺寸封装便于电源模块的整体布局；

2、硕凯电子作为国内防护器件的领导者，其放电管和压敏电阻等产品一直是其主打产品。

压敏电阻选型主要考虑压敏电压和峰值电流参数，输入AC220V，加上±10%的波动和开机浪涌，一般选择压敏电压在360V左右，峰值电流50A。根据参数推荐硕凯电子的14D系列压敏电阻14D621K，其压敏电压为558-682V，峰值电流可达50A。同时高达6kA的通流容量，保证了压敏电阻的使用寿命和可靠性。

气体放电管一般需要根据工作电压和脉冲峰值电压来选择合适的产品，参考上述压敏电阻的参数，脉冲峰值电压需要达到360*1.414=509VDC。推荐硕凯电子的SC2E8系列气体放电管SC2E8-600HL，其脉冲放电电压可达600VDC，同时高达10KA的冲击电流，提高整体防雷电路的可靠性。绝缘电阻达到1GΩ可以大大降低对壳的漏电流，避免产品外壳有带电的风险。

综上所述，硕凯电子的压敏电阻、气体放电管产品加上电安科技的保险丝产品，可以完全实现ACDC电源模块防雷电路器件国产化选型。以上是针对AC220V 1KW ACDC电源的国产化选型介绍，其整体推荐参数如图3所示。针对其他输入和功率段的电源，都有满足要求的国产化选型推荐，有兴趣的朋友欢迎在世强电商平台上的选型帮助功能下留言。

【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。

【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。
