摘要
激光供能作为一种新的供能方式逐步为高压电子式电流互感器设计所采用。设计了一种用于高压电子式电流互感器的激光供能方案,提出了一种激光供能与异步串行通信复用的功率激光器驱动方法,具体给出了激光器的驱动电路、保护电路和自动恒温控制方案,并在此基础上提出了MCU控制系统的模型。最后对高压侧的高效率光能-电能转换电路进行了设计。
Optical power supply is adopted gradually in high voltage electronic current transformer as a new method of power supply. This paper presents a scheme of optical power supply in ECT, proposes a drive method combined by laser power supply and serial communication. The driving and protecting circuit as well as automatic constant temperature control system of LD are given, and the model of MCU control system is set up. Finally, the design of the efficient optical-electric converting circuit at high voltage side is carried out.
