| 摘 要： | 介绍了电子式互感器的系统组成,比较了两种光传输系统的特点,提出了用同步时钟模拟异步发送的数据光传输方案。一次侧利用16位串行A/D结合单片机控制实现了数据的单光纤发送,二次侧的数据接收利用CPLD技术完成同步时钟的解调及串行数据的并行转换。利用该方案实现的电子式互感器系统满足0．2级的准确度要求。

| Abstract: | The system of the electronic transformer is described. Two types of optical transmission systems are compared. The optical data transmission scheme with synchronous clock imitating asynchronous transmission is presented. The data transmission through single optical fiber is realized with 16-bits serial output A/D converter and single chip computer. Demodulation of synchronous clock and converting serial to parallel transmission of data are done with CPLD at secondary side. The linearity characteristic of the electronic transformer reaches level 0.2. |
