| 摘要: |
| 通过对电流互感器式“电流－电压”变换器和电抗变压器式“电流－电压”主换器变换特性的分析，结果表明：对于不同频率的电流，电流互感器式“电流－电压”变换器对它们的变换几乎是相同的，而电抗变压器式“电流－电压”变换器将按频率的倍数进行变换，放大高频分量，抑制低频分量，通过从事继电保护装置研制的实践亦证实了不同的继电保护装置，采用不同形式的“电流－电压”变换器，使保护装置的电流变换环节更加完善。 |

| Abstract: |
| The characteristics analysis of two different current -to-voltage convertors,current transformer an reactance transformer,shows that the current transformer has the same converting effect on the currents with different frequencies,while the reactance transformer transforms has various converting effect.The reactance transformer amplifies the high frequency components and restrains the low frequency components.According to the analysis and based on author's experience in developing protection devices,it is better to choose different current-to-voltage convertors for different types of relay. |
| Key words: current transformer,reactance transformer,linear converting |
