避雷器分为以下4种，有金属氧化物避雷器，线路型金属氧化物避雷器，无间隙线路型金属氧化物避雷器，全绝缘复合外套金属氧化物避雷器，可卸式避雷器。避雷器的主要类型有管型避雷器、阀型避雷器和氧化锌避雷器等。每种类型避雷器的主要工作原理是不同的，但是它们的工作实质是相同的，都是为了保护通信线缆和通信设备不受损害。希望能帮到您。

你好，总体分两类,电力用避雷器和通信用的信号避雷器；
电力避雷器有高压避雷器和通常在各级配电箱使用的避雷器(通流能力各不同,注意安装时的参数),火花间隙型,MOV氧化锌压敏电阻型,TVs瞬态抑制二极管,后两者属于限压型的.第一个是开关型. 信号避雷器有天馈用,通信用避雷器,使用时串联于线路中,使用中注意插入损耗对信号质量的影响.
希望回答对你有帮助。

避雷装置的种类有要分为接闪器、电源避雷器、信号型避雷器、天馈线避雷器四大类：

　　1、接闪器。接闪器就是专门用来接收直接雷击(雷闪)的金属物体。一般有三种形式：避雷针、避雷带和避雷网。它位于建筑物的顶部，其作用是引雷或叫截获闪电，即把雷电流引下。

　　2、电源避雷器。电源防雷器是浪涌保护器中最常用的一种，主要是针对电源系统所选用的浪涌保护。其主要作用是防止雷电和其他内部过电压侵入设备造成损坏。

　　3、信号型避雷器。信号型避雷是浪涌保护器的一种，其主要作用是将被保护线路接入等电位系统中，并迅速对大地释放因雷击引起的高压脉冲能量，降低各接口间的电位差，起到保护用户设备的作用。

　　4、天馈线避雷器。天馈线避雷器适用于GSM移动基站、PHS小灵通基站、卫星接收机、对讲机基站等开馈线路、射频线路雷电及电涌的防护。具有输出残压极低，可有效保护接收设备，对从天馈线感应而来的雷电高压脉冲具有高效防御功能。
