【技术】一文介绍GDT气体放电管的主要参数及使用注意事项
GDT气体放电管是一种用于保护电子设备的电气保护元件。本文介绍GDT气体放电管主要参数和需要注意的事项。其主要参数包括:
1.额定电压(Rated Voltage):气体放电管的工作电压范围。
2.漏电流(leakage):固定电压下,GDT气体放电管的漏电流。
3.动作电压(Strike Voltage):GDT气体放电管开始带电放电时的电压值。
4.保护电流(Holding Current):气体放电管正常工作时的电流值。
5.时间到保护电流和电压(Time to Protection Current/Voltage):气体放电管能够最终启动的保护电流和电压下的反应时间。
使用GDT气体放电管时需要注意以下几点:
1.所选择的GDT气体放电管要满足设计要求,不能超过其最大额定电压和电流。
2.气体放电管通常安装在需要保护的电路入口端,以提供最佳电路保护。
3.GDT气体放电管的带电放电后,会导致其内部电容器被放电,会形成瞬间高压,因此要采取维护好地线和引导电线,并且避免直接接触。
4.不要擅自更改气体放电管的参数或进行拆卸和修理,以避免电气危险。
5.正确选择和使用GDT气体放电管可以大大提高电子产品的耐电压水平,减少电路故障,延长电子产品的使用寿命。
