【摘要】 本文在研究灭弧室驱弧磁场、I—B相差、起弧相角、分闸速度等切断能力影响因素的基础上,提出了灭弧室合理的磁场设计,试验证明,对本文所述的灭弧室结构,新设计能显著提高切断能力。更多还原

【Abstract】 Based on the investigation of the effect factors on braekingcapacity, such as the magnetic fild, I-B phase differences , phase angle at the arcing instant, opening speed etc., an appropriate magnetic fild construction have teen proposed. Direct test was shown that the new construction can increase pronounced breaking capacity.更多还原
