它至少含有一个非线性元件，过去常称为“避雷器”或“过电压保护器”。

电涌（又称浪涌）和峰值电压电涌和峰值电压（脉冲）是指“常规”电压的增加，通常由剧烈变动或电力需求的增加而引起。

打开大功率电器、吸尘器、空调、洗衣机都可以引发电涌和峰值电压。

任何一种类型的干扰都能够损坏电子设备。

超出实际维修范围。

另外，恶劣天气（闪电）和电力公司的日常拉关闸及维修工作都会给电源线带来破坏性的电涌。

为什么需要电涌保护器？即使是很小的电涌或峰值电压也可以最终摧毁或影响昂贵的电子设备的性能，如电脑、电话、传真、电视、音频/视频设备和其它家用电器和工具。

电脑芯片的普遍使用越发需要电涌保护，因为这些芯片往往对电压波动都十分敏感。

电涌保护器如何工作电涌保护器像电力海绵一样，能够吸收危险的额外电压，防止大多数这样的电压进入您的敏感设备。

具有电话线保护功能的防涌插座可给您的用电设备提供最完备的保护，以防受到有害电涌侵害。

电涌和尖峰电压会通过电话和电源线破坏或降低您贵重电子设备的性能水平。

完善的电涌保护功能可随时保护诸如计算机、电话机、调制解调器、电视机及其它家庭电子设备和电器用具。

防浪涌插座，可以使您的用电设备及电话设备防雷击、稳定工作、延长电器使用寿命。

产品特点：保护电话/DSL/宽带线路保护高达45,000安的最大尖峰电流提供高达1780焦耳能级的最大保护过滤电磁/无线电频率干扰（EMI/RFI）在1纳秒内响应以保护设备电涌保护器电涌保护器(Surge protection Device)是电子设备雷电防护中不可缺少的一种装置，过去常称为“避雷器”或“过电压保护器”英文简写为SPD。

电涌保护器的作用是把窜入电力线、信号传输线的瞬时过电压限制在设备或系统所能承受的电压范围内，或将强大的雷电流泄流入地，保护被保护的设备或系统不受冲击而损坏。

浪涌保护器（SPD）保护模式详解

浪涌保护器（SPD）保护模式详解浪涌保护器( SPD )保护模式详解——瑞隆源电子一、SPD保护模式的定义用以限制瞬时过电压和泄放电涌电流的电器，它至少应包括一种非线性元件。

在一般平时的工作中也称“浪涌保护器”、“浪涌防护器”、“电涌保护器”、“防雷器”等。

二、浪涌保护器的保护模式1.什么是保护模式：SPD可连接在L（相线）、N（中性线）、PE（保护线）间，如L-L、L-N、L-PE、N-PE，这些连接方式称为保护模式，它们与供电系统的接地型式有关。

按GB50054-95《低压配电设计规范》规定，供电系统的接地型式可分为：TN-S 系统（三相五线）、TN-C系统（三相四线）TN-C-S系统（由三相四线改为三相五线）、IT系统（三相三线）和TT系统（三相四线，电源有一点与地直接连接，负荷侧电气装置外露可导电部分连接的接地极与电源接地极无电气联系）。

目前，浪涌保护器的保护模式大部分是4个保护模式（L-PE，N-PE），即三根火线分别与保护线，中性线与保护线连接。

4模式保护，见图1的最右边的4个模式。

还有一部分是全模式（L-L、L-N、L-PE、N-PE），即三根火线之间，三根火线分别与保护线，三根火线分别与中性线，中性线与保护线。

全模式最多有10模式，在常用的3相星形接地方式中就是10模式。

2.全模保护的浪涌保护器的结构：深圳市瑞隆源电子有限公司专业制作各种不同规格的陶瓷气体放电管，放电管，防雷器，避雷器等等。

TEL=0755********在我国通常使用的4模式保护器中（参照IEC标准），常用的是4个单片组合在一起，三个单片分别连接火线与保护线（L1-G，L2-G，L3-G）另一个单片连接中性线与保护线（N-G）。

4模式的浪涌保护设备没有对浪涌电流经过的所有可能的线路都进行保护，如火线—火线之间（L1-L2，L1-L3，L2-L3），火线—中性线（L1-N，L2-N，L3-N）。

而北美电气电子工程师学会(IEEE)对电涌保护设备有明确规定：用于3相4线+地电路的电涌保护设备需要对电流经过的所有可能的线路进行保护，它们包括L-L，L-N，L-G，N-G。

基站电源防雷器(SPD)接线方式

3.3.2 在直流配电系统中分为正极与负极（V+-V-）、正极与地线（V+-PE）、负极与地线（V--PE）之间等三种保护模式。
注：限压型SPD和具有限压特性的组合型SPD可用于任一保护模式。电压开关型SPD和具有开关特性的组合型SPD因存在尚待进一步研究的续流遮断能力及其试验方法问题，不宜在除N-PE外的其它保护模式中推广使用
是防雷箱的残压。
➢假设通过防雷箱的雷电流为20KA：
➢防雷箱的残压为1500V
➢L1的残压＝L1*di/dt＝1uH*20KA/10uS＝2KV
➢L2的残压＝L2*di/dt＝5uH*20KA/10uS＝10KV
➢则最终开关电源交流输入侧得到的剩余电压（残压）＝2＋1.5＋10KV＝13.5KV。
➢远远大于防雷箱的1500V电压，也远远超过开关电源2500V的耐压，结果失去了防雷的保护效果，

什么是SPD（SPD介述）
▪ SPD这一名词英语全称是surge protectiye device其译意为电涌保护器，是限制雷电反击、侵入波、雷电感应和操作过电压而产生的瞬时过电压和泄放电涌电流（沿线路传送的电流、电压或功率的暂态波。其特性是先快速上升后缓慢下降）的器件。
b) 另一种是TT系统，对于TT系统供电方式必须选用3+1模式的SPD。
以上内容在《通信局站在用防雷系统技术要求和检测方法》中已经给予了详细讲解，因此不再赘述。

浪涌保护器(SPD)与过电流保护器的配合使用

中的任何一个动作发生，就可使主触头分断电路。当电路正常工作时，电磁脱扣
为防止ＳＰＤ的失效故障，ＳＰＤ前端应安装熔丝或热熔断器等过电流保护器。其前端过电流保护器的保险电流值与主电路上过电流保护器的保险电流值不宜小于１：１．６１４１。ＳＰＤ失效模式为短路时，可能会影响受保护系统和设备的正
流变大时，温度逐渐升高还会引发火灾。２－ＳＰＤ和低压短路保护器件的原理
２１ＳＰＤ、空气型断路器、熔断器的工作原理
达到了过电流保护器的响应时间ｔ３，ｌ￣ｌｌｔｌ＋ｔ２＞ｔ３，则过电流保护器可能会动作。而过电压的泄流时间与ＳＰＤ的泄流阻抗Ｚ１和过电流保护器的泄流阻抗ｚ２有关．
内，是建筑防雷工作中必不可少的一部分。按工作原理分为限压型浪涌保护器、组合型浪涌保护器、电压开关型浪涌保护器。空气型断路器是低压配电系统中最常使用的低压断路器。它的三个触头串联在三相主电路中，电磁脱扣器的线圈及热脱扣器的热元件与主电路串联，欠电压脱扣器线圈与主电路并联。当断路器闭合后，三个主触头保持闭合状态。当电磁脱扣器吸合或热脱扣器的双金属片受热弯曲或欠电压脱扣器释放，这三者
短路情况。５．１开关型ＳＰＤ￣ｎ限压型ＳＰＤ的缺陷
器线圈产生的电磁力不能将磁铁吸合，而当电路发生短路，出现很大过电流时，主触头断开，切断主电路，若电路发生过载，但又达不到电磁脱扣器动作的电流时，触头分开来断开电路，起到过载保护作用，若电源电压下降较多或失去电压时，同样导致触头断开而切断电路，起到欠电压或失电压保护作用。空气开关是低压断路器的其中一种，它是一种只要有短路形成回路就会跳闸的开关。熔断器是一种结构简单、使用方便、价格低廉的起保护作用的电器，它串联在被保护电路中，当线路或电气设备的电流超过规定值足够长的时间后，其自身产生的热量能够熔断一个或几个特殊设计的和相应的部件，断开其所接人的电路并分断电源，从而起到保护作用［１】熔断器广泛应用于高低压配电系统和控制系统以及用电设备中，作为短路和过电流的保护器，是应用最普遍的保护器件之一。３ＳＰＤ串联过电流保护器的作用ＳＰＤ通常并联或串联安装在被保护设备端。当瞬态电涌未到时，呈高阻态，被保护电路正常工作，当瞬态电涌到来时，迅速转变为低阻态，电涌电流旁路，

而且在分断故障电流后一般不需要变更零部件。

目前，已获得了广泛的应用。

▲电的产生、输送、使用中，配电是一个极其重要的环节。

配电系统包括变压器和各种高低压电器设备，低压断路器则是一种使用量大面广的电器
▲断路器应垂直安装，且在安装前应先检查断路器铭牌上所列的技术参数是否符合使用要求。

▲通电前应人工操作几次断路器，其机构动作应灵活可靠、无阻滞现象。

电涌保护器（SPD）工作原理和结构及选择及安装

电涌保护器（SPD）工作原理和结构及选择及安装电涌保护器（SPD）工作原理和结构电涌保护器（Surge protection Device）是电子设备雷电防护中不可缺少的一种装置，过去常称为“避雷器”或“过电压保护器”英文简写为SPD.电涌保护器的作用是把窜入电力线、信号传输线的瞬时过电压限制在设备或系统所能承受的电压范围内，或将强大的雷电流泄流入地，保护被保护的设备或系统不受冲击而损坏。

电涌保护器的类型和结构按不同的用途有所不同，但它至少应包含一个非线性电压限制元件。

用于电涌保护器的基本元器件有：放电间隙、充气放电管、压敏电阻、抑制二极管和扼流线圈等。

一、SPD的分类1、按工作原理分：1.开关型：其工作原理是当没有瞬时过电压时呈现为高阻抗，但一旦响应雷电瞬时过电压时，其阻抗就突变为低值，允许雷电流通过。

用作此类装置时器件有：放电间隙、气体放电管、闸流晶体管等。

2.限压型：其工作原理是当没有瞬时过电压时为高阻扰，但随电涌电流和电压的增加其阻抗会不断减小，其电流电压特性为强烈非线性。

用作此类装置的器件有：氧化锌、压敏电阻、抑制二极管、雪崩二极管等。

3.分流型或扼流型分流型：与被保护的设备并联，对雷电脉冲呈现为低阻抗，而对正常工作频率呈现为高阻抗。

扼流型：与被保护的设备串联，对雷电脉冲呈现为高阻抗，而对正常的工作频率呈现为低阻抗。

用作此类装置的器件有：扼流线圈、高通滤波器、低通滤波器、1/4波长短路器等。

按用途分：（1）电源保护器：交流电源保护器、直流电源保护器、开关电源保护器等。

（2）信号保护器：低频信号保护器、高频信号保护器、天馈保护器等。

二、SPD的基本元器件及其工作原理1.放电间隙（又称保护间隙）：它一般由暴露在空气中的两根相隔一定间隙的金属棒组成，其中一根金属棒与所需保护设备的电源相线L1或零线（N）相连，另一根金属棒与接地线（PE）相连接，当瞬时过电压袭来时，间隙被击穿，把一部分过电压的电荷引入大地，避免了被保护设备上的电压升高。

【关键词】浪涌保护器；后备保护；退耦；保护模式；SPD连接线引言2018年在 “十三五”建设项目实施前，大部分广播电视发射台站已实施了防雷设施,如：建筑物防雷、配电柜内配套安装了SPD ,人工接地装置等。

但是雷击现象仍时有发生，轻者击坏SPD、损坏广播设备、重者存在严重停播事故及人身安全的风险。

本次十个广播电视无线发射台站的防雷建设项目中，主要对发射台站低压配电系统的浪涌防护及接地做重点整改，本文主要就台站电源线路浪涌侵入的防护措施作探讨。

1 台站电源线路的浪涌防护常见问题：根据日常的设备维护和设备雷击损坏记录，因雷击引起的大部分设备损坏，均来自低压配电线路的雷电浪涌入侵。

台站电源线路的浪涌防护，是整个防雷工程的重中之重，在雷击事故发生前，如何发现防护存在的问题，如何解决问题，才能把雷电造成的灾害降到最低限度。

1.1 SPD选型类型不符合防雷规范要求,作为第一级防护的SPD尤为突出：按照相关防雷技术要求，台站变压器低压侧外电引入(市电)的总配电箱处，应配置I级试验浪涌保护器作为第一级防护。

但是这一级的SPD往往是配电成套厂家配套安装，配置的SPD质量掺差不齐，主要表现为标称放电电流过小(In=20-40kA(8/20μS)不等)、采用限压型SPD。

SPD-6A-10A串联型防雷器和SPD-6B-10B并联型防雷器介绍

SPD-6A/10A串联型防雷器和SPD-6B/10B并联型防雷器介绍我们照明行业常说的防雷器，专业名称应该是浪涌保护器或突波吸收器。

浪涌也叫突波，就是超出电器正常工作电压的瞬间过电压，维持时间仅百万份之一秒。

浪涌主要有两类来源：一类是来自外界雷电感应，云层与大地之间的雷击放电，闪电电流高达数十、甚至数千安培，强大的雷电流产生的电磁波在电源线或信号线上感应极高的脉冲电压;第二类是来自工厂内部感性负荷电器（比如大功率电机、变压器、感应加热炉、电梯/卷扬机等）开关操作时，在开和关的瞬间，电感产生的反向电动势（反向电压）非常高，高达几千伏的过电压。

第三类是户外直接雷击，巨大的电流在数微秒时间内流下大地，使大地电位迅速抬高，造成反击事故。

雷电流流经电气设备产生极高的热量，造成火灾或爆炸事故，厉害的雷电，不要说一台小小的灯具，即便是大树、建筑物都能被击倒或烧毁，这类雷击，当然不是靠防雷器这类小小的电器盒子来防护的，而是要通过灯具（外壳）可靠接地，让雷电流快速泄放到大地，尽量减少雷电的损害。

比如很多高大建筑物或吊塔、灯塔都装有密集的避雷针。

我们在此讨论的是如何防护第一类和第二类的浪涌，即雷电感应电磁波产生的浪涌（主要发生在比较空旷的田野山头）和工厂感性负荷开关产生的浪涌。

防雷器的工作原来是这样的，当电源输入端接收到较大浪涌时（超过500V），防雷器内部能量吸收器件和放电管就动作，迅速把脉冲能量吸收消化（俗称差模防护）或对地泄放（俗称共模防护），将脉冲衰减至700V或900V以下的安全值，不让后端的灯具电器受到浪涌的冲击，从而保护灯具。

我公司在LED高压线性恒流方案光电模组的防雷技术已取得国家专利证书，在行业内首次提出了分级防雷设计概念，最大限度的发挥了防雷器的作用。

市场上销售的防雷器主要分两类，一类是串联型，一类是并联型。

我公司有SPD-6A/10A串联型防雷器和SPD-6B/10B并联型防雷器。

这两类产品的外部接线方式不同，防护效果在某些场合是有差别的。
