变压器是利用电磁感应原理传输电能或电信号的器件,它具有变压、变流和变阻抗的作用。变压器的种类很多,应用十分广泛。随着高考试题进一步优化和高校自主招生考试的全面推开,变压器问题已经成为两类考试命题的一个重要切入点。下面我们就变压器的基本结构、工作原理及其应用做一简要分析。 Transformer is the use of electromagnetic induction principle of transmission of electrical energy or electrical devices, it has the transformer, variable current and variable impedance role. Many types of transformers, a wide range of applications. With the further optimization of entrance examination papers and the full liberalization of college entrance examination, the transformer problem has become an important entry point for two types of examination questions. Below we make a brief analysis of the basic structure of the transformer, working principle and its application.
