限流电抗器
current-limiting reactor
x 10nl一u drankongql限流电抗器(eurrent一limiting reactor)与翰电线路申联用以限制电力系统短路电流的电扰器,又称串联电抗器。通常安装在线路出线段或母线段之图1限流电抗器接线图间(见图1)。当线路或母线发生故障时,限流电抗器能使后接设备的短路电流不超过容许值,并使母线电压保持在额定电压的60%~70%之间。带有中心抽头和两个对称份的电抗器称为分裂电抗器,使用时中心抽头接电源,两份接负荷(见图z)。在多台变压器和多回线路的史电所,限流电抗器还可用来进行阻抗匹配,使变电所达到最佳运行状态。 限流电抗器在额定电流下的电压降,通常为额定电压的3%~10%。分裂电抗器两个臂的电抗值和载流量相同,正常工作时两臂的电流方向相反,大部分磁通相互抵消,从而图2分裂电抗器接线图其电压降减小,当一有发生故障时,磁通不能抵消,电抗值增大,从而起到限流作用。 额定电压在35 kV以下、额定电流为200~3000A的户内式限流电抗器,通常为空芯混凝土柱式结构。额定电压在35kV及以上的限流电抗器,一般为空芯油浸户外式结构,油箱内壁加装磁分路或磁屏蔽.近年来又研制成一种新型玻瑞纤维结构的空芯式电抗器,其造型简单轻巧,适应于户内和户外。 限流电抗器通常都做成单相式,组成三相时有三相垂直重登、两相垂直重亚一相并列、三相并列等三种排列方式(见图3)。排列方式不同,其绕组的绕制方向和匝数要求也不同。由于限流电抗器的磁通在空气中形成回路,所以安装时与屋顶、四壁和地面需要保持一定的距离。骤篡,赢图3电抗器三相排列方式(a)三相垂宜t登;(b)两相垂1t登,一相并列;(c)三相并列
