摘　　要：随着断路器电压等级的不断提高,世界上各大容量试验站纷纷提出了适用于特高压断路器容量试验的试验回路。这些回路各有特点,为了找出更有优势的试验回路,笔者进行了一些分析和研究。文章主要介绍了试验回路的原理,分析了回路中辅助开关及产品的电弧电压对试验的影响,并计算了断口间及套管上的电场分布。通过比较试验回路在这些方面的特点,提出了关于试验站选择特高压断路器容量试验回路的建议。With the increasing of the voltage levels of circuit breakers, high power test stations in the world put forward the suitable test circuits for UHV power test. This test circuits have their own characteristics. To find out better test loop, the author does some analysis and research： introduces the principle of the test circuits, measures the arc-voltage of the breakers in the circuit and analyzes it＇s influence on the test, calculates the electric field distribution of the interrupters and bushing. At last, some suggestions for laboratory choosing UHV power test circuit are given by comparing characteristics of test circuits in these areas.
