电路保护方案设计过程中,就要开始被动保护元器件的选择,电路保护元器件可分为过压保护器件和过流保护器件。防浪涌过电压保护器件之一陶瓷气体放电管GDT,其内部是由一个或一个以上放电间隙内充有惰性气体构成的密闭器件。陶瓷气体放电管GDT可以承受高达 ...

目前我国气体放电管市场国产化程度较低，国外企业仍占据市场主导地位，未来国内市场国产替代空间巨大。 气体放电管，简称GDT，又称陶瓷气体放电管，是指一种间隙式的防雷保护元件，是作过电压保护用避雷管或天线开关管的细分品类。根据结构不同，气体 ...

气体放电管是一种利用惰性气体（如氖、氩、氪或其混合物）在特定高电压下发生气体放电现象（辉光放电、弧光放电）来实现过电压保护的电压开关型浪涌保护器件。 核心原理： 在正常工作电压下，GDT呈现极高的阻抗（通常>1GΩ），相当于开路，对电路无影响。

陶瓷本身具有抗电性能好、抗压强度高、不容易氧化、良好抗腐蚀、热稳定性佳，因此气体放电管一般采用陶瓷作为封装外壳，陶瓷气体放电管内充满电气性能稳定的惰性气体，再通过烧结、反复老练测试制成，放电管的电极一般有两个电极、三个电极两种结构。
