摘　　要：阐述了过振荡系数γ和振荡频率f的调节在分断能力试验中的意义,列出了相关标准对这些参数的要求以及调整电路的连接方法。在此基础上探讨了调节电路时所需要注意的事项并给出了相应的理论分析。最后模拟不同试验条件下的试验,而试验波形表明这些注意事项是负载调整电路调节的关键点。Adjusting the oscillatory frequency f of transient recovery voltage and the overoscillatory factor γ are the difficult point for low voltage apparatus breaking capacity test. This adjusting meaning for breaking capacity test was expounded. The requirements about these parameters from the related standard and the connection methods of adjusting load circuit were listed. The cautions were reasearched and theoretically analyzed. Different test conditions were simulated and the test waveform shows that these cautions are the key points for adjusting load circuit.
