摘　　要：电抗器在短路状态下线圈通过的热短路电流和机械短路电流呈数倍增加,其线圈强度设计能否抵抗电磁力作用,抗短路的能力计算和核算对产品设计及运行安全预测都有非常重要的意义。应用电磁理论计算出电抗器磁感应强度分布相应的电动力计算和核算,结果表明具有优良的抗短路能力。Under short circuit condition, the thermal and mechanical short circuit current passing through the coil of reactor increases in multiple times.Whether the design of its coil strength can withstand the stress of the electromagnetic force, the ability calculation to withstand short circuit have very significant to the product design and safe operation.The magnetic induction strength distribution in the reactor by way of electromagnetic theory is calculated, and thus the corresponding electromagnetic force is checked.It is shown by the result that it has excellent short circuit withstand ability.

关 键 词：电抗器 抗短路的能力 磁感应强度
