摘要
运行中交变电场在光纤复合电缆的非磁性金属光单元上产生感应电势,感应电势的大小是决定光单元能否使用非磁性金属材料的一个主要因素。通过计算,认为光纤复合电缆中非磁性金属光单元的感应电势影响可忽略,光单元可以使用非磁性金属结构。
The induced voltage on non-magnetic metallic optic fiber unit in a composite cable will be generated be- cause of the influence of AC electric field when the power cable is in operation. The value of the induced voltage is one of the major factors to decide whether non-magnetic metallic material can be used in an optic fiber unit. This paper calculates the induced voltage on non-magnetic metallic optic fiber unit in three-core power cable. The influence of in- duced voltage may be ignored. Optical fiber unit may be made of non-magnetic metallic material.
