| 摘要: |
| 目前一二次融合成套化柱上断路器的单相接地故障处置准确率低，亟需开展单相接地故障处置考核验证。在运行现场开展单相接地试验受制于安全风险和用户供电可靠性的影响，不易多次开展。通过建立10 kV真型配电网试验平台，实现了被试品快速接入，灵活复现配电网单相接地故障。提出了一二次融合成套柱上断路器单相接地故障处置真型试验方法，有效验证了一二次融合成套柱上断路器单相接地故障处置功能与处置准确率，发现了9项不合格原因。通过真型配电网试验平台的建立，提高了配电网设备入网质量，有效支撑配电网供电可靠性进一步提升。 |

| Abstract: |
| At present, the primary and secondary integration column circuit breaker single-phase ground fault disposal function and accuracy rate is lower. Thus it is urgent to carry out assessment and verification of single-phase ground fault disposal. A single-phase ground test at an operational site is subject to the safety risk and user power supply reliability. It is not easy to carry out frequently. In this paper, a 10 kV real distribution network test platform is built. The test object is quickly connected to the test position. The single-phase ground fault can be reproduced flexibly. A single-phase ground fault treatment true test method of a primary and secondary fusion complete column circuit breaker is put forward. The disposal function and accuracy rate of the primary and secondary fusion complete column circuit breaker are effectively verified. Nine unqualified problems are found in the test. Through the establishment of a real distribution network test platform, the quality of equipment is improved, and the reliability of the network power supply is further improved.
