电力系统开断电感负载过电压
inductance switching-off overvoltage in electric power system

  d一onl一x一tong kolduond旧ngan fuzo一guod旧nyo电力系统开断电感负载过电压(inductanceswitehing一off overvoltage in electrie powersystem)开断电感负载时由于电流在自然过零之前被强制截断导致瞬态振荡所引起的过电压。电感负载可以是空载和轻载变压器、并联电挽器和电动机等。 开断电感负载过电压的机理如图所示:电感电流i(t)在10处被截断,截流瞬间,电感负载L中储有磁场能LI02/2,负载杂散电容C中储有电场能CUoZ/2,截流后,这些能量将在LC回路中振荡,在全部能量转化为电场能的瞬间,电容上电压(即电感负载两端的电压)将达最大值u。一刃万不不Z夕万。如果电流在幅值I二处被截断,则过电压可达um二I,丫Z万。丫Z夕万为电感负载的特征阻抗。开断感性负载时的过电压(a)等值电路;(b)波形示意 开断电感负载过电压的幅值与负载的特性、断路器的截流能力有关。电感负载的杂散电容C值一般很小,特征阻抗很大,所以过电压有较高的值。断路器截流能力愈强,过电压幅值越高。如有的真空断路器在合闸电感负载时,由于过流保护动作将较大的激磁涌流截断,引起很高的过电压而将断路器损坏。由于断路器灭弧过程的分散性,开断电感负载的过电压具有统计性。 限制开断电感负载过电压的措施有:减小电感线圈的励磁电流(例如采用冷轧矽钢片),增大与电感并联的电容C(例如在变压器中采用纠结式绕组),可降低开断电感负载过电压。开断电感负载过电压的最大能量为众mZ/2,其绝对值不大,可用为防止雷电过电压的进雷器加以限制。
