变压器为什么能变压又是怎样变压的 ?变压器除了变压以外还能变什么又不能变什么 ?这是大家经常在思考的一个问题 .下面笔者根据变压器的工作原理来谈谈变压器的“三变三不变” .一、变电压1 .理想变压器的原理图 1是变压器原理图 .把变压器原线圈与图 1电源相连 ,副线圈与负载 Why can a transformer transform and how can it be transformed? What can a transformer change in addition to a transformer? What does this change? This is a problem that everyone often thinks about. Here’s how the transformer works, based on the working principle of the transformer. Change to three.” I. Variable voltage 1. Principle of an ideal transformer Figure 1 is a schematic diagram of a transformer. Connect the primary coil of the transformer to the power supply of Figure 1, the secondary coil and the load.
