根据雷击的强度和频率,浪涌保护器可能在一次或数百次高电压冲击后失效。 当然,在每次雷击之后,至少每年一次,需要验证浪涌保护器的功能。 验证过程通常十分繁琐。 使用 FieldConnex® 浪涌保护器可以完全省略此项工作。 

FieldConnex® 浪涌保护器可选配集成诊断功能,可通过高级诊断模块指示其使用寿命是否结束。控制室收到相关消息并显示受影响的分支。浪涌保护器的指示灯显示故障状态并及时更换。

如果现场总线项目中配置了高级诊断模块和段保护器及诊断功能浪涌保护器,则无需额外的改造工作即可获得网段状况并及时维护。 


安装方便,易于更新

这种浪涌保护器无需额外接线。 浪涌保护器可以加装在 FieldConnex® 段路保护器 (例如R2-SP*)上。


满足工厂设计要求

FieldConnex®浪涌保护器 满足各地安装和维护规范。一些产品在带电情况下允许维护和更换。屏蔽线可以硬接地或通过气体放电管接地并满足以下常规屏蔽接地技术要求:

  • 单点接地
  • 多点接地
