| 中文摘要: |
| 为了检查220 kV六氟化硫组合电器安装后的绝缘性能，详尽阐述了对其进行交流耐压试验的步骤与操作方法，试验时特别要注意以下事项:试验前应对相关人员进行培训，促使其加强自我保护意识，对于未现场操作过高压耐压试验的调试人员，要在具有相关资质人员的指导下进行；耐压试验过程中要注意环境湿度与气体、粉尘对设备绝缘性能的影响，试验一般选在晴天进行；变频电源的输出值和额定容量能否达到耐压水平将影响整个试验的顺利进行；采取相应的辅助仪器来监测GIS耐压试验过程中是否放电以及放电部位，便于后期拆装检查与更换。 |

| In order to check the insulation performance of 220KV sulfur hexafluoride combination electric appliance after installation, this paper describes the steps and operation methods of AC withstand voltage test in detail. Special attention should be paid to the following items during the test: before the test, relevant personnel should be trained to strengthen their self-protection awareness, and the commissioning personnel who have not operated the high voltage withstand voltage test on site should be under the guidance of relevant qualified personnel. Whether the output value and rated capacity of the variable frequency power supply can reach the withstand voltage level will affect the smooth progress of the whole test. The corresponding auxiliary instruments are used to monitor the discharge and the discharge position during the GIS withstand voltage test, which is convenient for later disassembly, inspection and replacement. |
