【应用】国产压敏电阻和陶瓷气体放电管助力光储一体机防雷方案，采用复合对称电路，共模、差模全保护

时间： 2022-12-07 来源：世强

技术问答

光伏一体机由于机箱是在户外，户外工作环境相对恶劣在硬件设计中需要做防雷设计，本文给客户介绍硕凯的硬件防雷方案。

防雷线路设计

该设计电路简单采用三颗压敏电阻和一颗陶瓷气体放电管，采用复合对称电路，共模、差模全保护，L、N可以随便接。根据客户设计推荐使用压敏电阻硕凯20D821K参数如下：

推荐硕凯陶瓷气体放电管SC2E5-1600DL参数如下：

推荐理由：

1. 压敏电阻直流电压为670V，满足客户设计需求；

2. 陶瓷气体放电管1600V±20%，满足客户设计需求；

综上所述，硕凯电子的防雷方案可以满足客户防雷设计需求。

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。

应用方案发布时间 : 2024-10-25

基于硕凯压敏电阻14D561K的IGBT快速开关电路，在浪涌抗干扰度试验中通过4级，且试验电压提高10%

本试验选用压敏电阻14D561K：击穿电压：504V-616V；通流量IPP高达4500A；位电压最大值 925V（50A）；工作温度：-55 至+125°C；具有通流量大、残压低、响应时间快等特点。当干扰电压达到一定值时，就会把两端的电压钳位住，从而保护IGBT不被击穿

【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。

【应用】10D681K压敏电阻用于洗衣机电源，满足差模2KV的浪涌测试

在洗衣机电源控制板中，由于存在接入市电电压不稳定以及雷雨天气产生的感应雷会对开关电源造成不良影响。针对此问题，硕凯电子给出了一个性价比较高的防护方案，只需要在输入端加一级压敏电阻就可以解决以上问题。可以过1.2/50uS组合波差模2KV的浪涌测试，测试次数正负五次，间隔60秒。该方案用到了普通型的压敏电阻10D681K。
