摘要
电子式互感器相对于传统的电磁式互感器具有诸多优点,未来在智能变电站中将得到更广泛的应用。激光供能是电子式互感器的重要供能形式,具有不存在电能死区、电源稳定、噪声小的特点。然而,激光供能回路的器件本身的缺陷和异常,将影响电子式互感器的稳定性和可靠性。本文首先阐述激光供能回路的工作原理,并结合在现场实际运行中的电子式互感器的激光供能回路发生的缺陷和异常案例,对供能回路的薄弱环节进行分析。针对施工环境污染、激光器失效、光纤回路异常等三类主要问题,给出了运行和维护的具体建议,为后续工程的实施和运维提供参考。
Compared with traditional electromagnetic transformer,electronic transformer has many advantages and will be widely used in intelligent substation in the future.Laser is an important form of energy supply for electronic transformer,which has the characteristics of no dead zone,stable power supply and low noise.However,the defects and anomalies of the components in the laser energy supply circuit will affect the stability and reliability of the electronic transformer.This paper f irst describes the working principle of the laser energy supply circuit,and combined with the defects and abnormal cases of the laser power supply circuit of the electronic transformers in operation,as to analyze the weaknesses of the energy supply circuit.At last,specif ic suggestions are put forward for the operation and maintenance to the three main problems,such as construction environmental pollution,laser failure and optical f iber circuit abnormality.
