220kV线路保护光纤通道构成与故障查找

Composition of the Optical Fiber Channel for 220kV Line Protection and its Troubleshooting

光纤通道对220kV及以上的线路保护至关重要,出现故障时也较为难查,因此,验收与查缺都应遵循相关方法进行,日常维护中也应重点关注通道状态,及时发现并解决问题。此外复用光纤通道涉及光电转换,光强标准较为清晰,而电的标准却无处可查,通道验收时应细化并明确该部分标准。

The optical fiber channel is of great importance to the 220 kV and above transmission line protection. While, the troubleshooting of the channel is difficult. Therefore, relevant procedures should be followed in the acceptance chec- king and the defect finding. In the daily maintenance, attention should be paid on the channel state to find and solve possible problems. In addition, the photoelectric conversion is involved in the multiplexing fiber channel. The standard for the light intensity is clear. While the electrical standard is absent, which should be clearly defined in the channel ac- ceptance.
