摘　　要：利用等效电路简单介绍了互感器二次回路保安性接地的基本概念,并通过模拟仿真方式较形象地解释了各互感器之间没有电联系的物理含义,指出了实际没有电联系的各互感器在各自接线端子箱就地接地可以简化二次回路接线,提高电网稳定运行水平的建议。Based on the equivalent circuit, the element concept of the secondary loop of transducer is introduced, and the physical meanings that no electrical connection exists among all transducers by simulation and emulation are explained. It is pointed out that if the connection of terminal box of every transducer has no relation in fact, the secondary loop connection can be brief, which improves the stability of electric network operation.
