2.产 品 详 情 资 料:
RELIANCE 30FR7731通信系统中的防雷由于HIMA通信设备现场布线的完全屏蔽以及系统接地的正确安装,可能不会出现闪电引起的高能量影响形式的接地问题。尽管如此,如果应设计防雷装置,则可通过使用特殊的防雷模块来提供。为此,目前使用的是Phoenix公司的MTRS485“DATA-MODUTRAB”型模块。该模块提供粗略保护(影响高达10 kA)和精细保护(影响达400 A)。RELIANCE 30FR7731防雷模块的连接符合以下要求:规划提示:由于其串联电阻,使用该防雷模块可减少最大可能的传输长度。RELIANCE 30FR7731
Lightning Protection in HIMA Communication Systems Due to the complete screening of the field wiring of HIMA communication systems and with correct installation of the system earthing problems in form of high energetic influences caused of flash of lightning might not occur. If nevertheless a lightning protection should be designed, it could be provided by using special lightning protection modules. For this the module of type MTRS485 "DATA-MODUTRAB" from Phoenix company is used up to now. The module is provided for coarse protection (influences up to 10 kA) RELIANCE 30FR7731and fine protection (influences up to 400 A). The connection of the lightning protection modules is according to the scetch below:Planning hints: The using of this lightning protection module reduces the max. possible transmission length because of its series resistance.RELIANCE 30FR7731
