自耦变压器与普通变压器有什么不同？

答：自耦变压器与普通变压器不同之处是：

（1）其一次侧与二次侧不仅有磁的联系，而且有电的联系，而普通变压器仅是磁的联系。

（2）电源通过变压器的容量是由两个部分组成：即一次绕组与公用绕组之间电磁感应功率，和一次绕组直接传导的传导功率。

（3）由于自耦变绕组是由一次绕组和公用绕组两部分组成，一次绕组的匝数较普通变压器一次绕组匝数和高度及公用绕组电流及产生的漏抗都相应减少，自耦变的短路电抗X自是普通变压器的短路电抗X普的（1-1/K）倍，K为变压比。

（4）若自耦变压器设有第三绕组，其第三绕组占用公用绕组容量。影响自耦变运行方式和交换容量。

（5）由于自耦变压器中性点接地，使继电保护的整定和配置复杂化。

（6）自耦变压器体积小，重量轻，便于运输，造价低。
