摘　　要：介绍了750kV断路器现场交流耐压试验的标准和时序,分析了基于串联谐振原理的试验方法及试验系统中各设备的具体参数。在此基础上配置出成套的750kV断路器现场交流耐压试验系统,通过实例成功完成了750kV断路器主回路及断口的交流耐压试验。Introduction was made to the standard and time sequence of site AC voltage withstand test of 750 kV circuit breakers. Analysis was made to the test methods based on serial resonance principle and actual parameters of different equipment in test system. On the basis of this, the site AC voltage withstand test system of a set of 750 kV circuit breakers was disposed. The actual example shows that the AC voltage withstand test for the main circuit and breaking outlet of 750 kV circuit breakers could be completed successfully.
