此外，还介绍了用具有引弧装置的合成迥路来作开断电流试验的方法，同时分析了试验结果。
Besides, the paper introduces the method of interrupting the current by means of a synthetic loop with an arc-ignition device and presents an analysis of the test result.
选用站用电系统设备时应满足短路时的动、热稳定，开断电流，开关上、下级的选择性等要求。
It should satisfy dynamic stability, thermal stability, switched-current and switch up-down selectivity in a short circuit while selecting the pumping station using electricity system equipments.
利用它对国产OFPI—220型SF_6断路器进行的计算结果表明，改变动触头排气孔位置及电弧对动触头内腔中气体的热效应可明显提高开断电流时灭弧室压力上升速度。
The results show that the position of the exhausting gas hole and the arc heat effects on the gas inside the hollow moving contact have obviously raised the pressure rising speed.
