| 摘 要： | 在69KV～765KV的供电系统中,光学电压互感器可提供模拟量或数字量输出,适应电力系统微机化、网络化、保护和测量智能化的要求,且体积小、重量轻、无爆炸危险,是一种理想的、新型电压互感器。但受BGO晶体双折射、传感器结构以及环境温度等的影响,使光学电压互感器的稳定性下降,因此要采取有效措施,提高其工作稳定性,保证电力系统的正常运行。

| Abstract: | In the 69KV- 765KV Power Supply System, optical voltage transformer can provide output of analog and digital, not only to meet power system micro-computerized, networking and intelligent protection and measurement requirement, but also small volume, light weight and no explosion danger, so is a ideal and new optical voltage transformer. But because of the influences include BGO crystal birefringence, structure of sensor, environmental temperature and so on, the stably of optical voltage transformer is descended. We should take effective measures,improved stability to ensure the normal operation of the power system. |
