关于 气体放电管避雷器 (GDT)
气体放电管（GDT）是一种专门的电气保护元件，旨在保护敏感的电子设备免受电压尖峰和浪涌的影响。它通常用于高压应用，并设计用于处理大电流和高电压。
GDT由一个玻璃或陶瓷管组成，其中充满了惰性气体的混合物，如氖、氩或两者的组合。管子的两端有两个电极，并封闭以防止气体泄漏。
当施加在电极上的电压大于GDT的额定值时，管内的电场变得足够强，使气体分子电离，释放出电子并具有导电性。这样可以安全地将多余的电能引导到地面，保护连接的设备免受损坏。
GDT广泛应用于电信设备、电力配电系统和其他需要对敏感电子器件进行保护的应用中。它们是一种可靠有效的方式，可以防止电气损坏，并确保电气系统的安全运行。
