| 摘要: |
| 研制了一种交直流合成大电流发生装置，其由交流电流源、直流电流源、交直流合成系统和监控与分析系统4个部分组成，分别介绍了各部分的工作原理和功能。该装置在交流大电流线路中串联大容量电容组用于阻隔直流，使得交流电流源回路和直流电流源回路形成交直流叠加的共同支路，且交流电流源和直流电流源互不影响。性能测试结果表明，装置的交、直流回路互不影响，且通过被测电流互感器的电流为交流大电流和直流电流的叠加。 |

| Abstract: |
| A high AC and DC hybrid generator is developed，which consists of four parts：AC source，DC source，current combination device and monitoring & analysis system. The working principles and functions of each part are introduced. Large-capacity capacitors are serially connected in AC circuit to prevent DC. There is a common branch of AC and DC circuits in the hybrid generator to superpose AC and DC together，without interfering in the AC or DC source. Results of performance test show that，the AC circuit and DC circuit are immune to each other and the high current flowing through the tested current transformer contains both AC and DC. |
