摘　　要：介绍了一种基于全光纤电流互感器的计量仪硬件设计。该计量仪能够对大电流、大温度变化的环境进行高精度的信号测量。具有响应速度快、测量数据准确、可靠性高的特点,并且具有实时显示、实时跟踪和可通过PC机记录处理数据的功能。该计量仪0.25%以下的相对误差满足了电力系统计量的需求。This paper describes the design of the current sensor based on full optical fiber. This equipment can have a high precise measurement even if under the circumstances of high input current and big change on temperature. At the same time, it has many functions, such as： real-time displaying and real-time tracking. It also can be recorded by the computer. The maxim relative error of this equipment is below 0.25% which satisfies the requirement of the electricity measurement.

关 键 词：电流互感器 实时跟踪 高精度
