| 变压器种类 Type of transformer 一、按芯种类分类 1. Classification by type of core 变压器按芯的种类不同，可分为空心变压器、磁芯变压器和铁芯变压器，它们的图形符号如图3-27所示。 According to the different types of cores, transformers can be divided into hollow transformers, magnetic core transformers and core transformers. Their graphical symbols are shown in Figure 3-27. 空心变压器是指一、二次绕组没有绕制支架的变压器。磁芯变压器是指一、二次绕组绕在磁芯（如铁氧体材料）上构成的变压器。铁芯变压器是指一、二次绕组绕在铁芯（如硅钢片）构成的变压器。 A hollow transformer is a transformer whose winding is not winded one or two times. A magnetic core transformer is a transformer consisting of one or two winding around a magnetic core, such as ferrite material. The core transformer is a transformer consisting of one or two winding around the core (such as silicon steel sheet). 二、按用途分类 Two. Classification by use 变压器按用途不同，可分为电源变压器、音频变压器、脉冲变压器、恒压变压器、自耦变压器和隔离变压器等。 Transformers can be divided into power transformers, audio transformers, pulse transformers, constant voltage transformers, autotransformers and isolated transformers. 三、按工作频率分类 Three. Classification according to working frequency 变压器按工作频率不同，可分为低频变压器、中频变压器和高频变压器。 The transformer can be divided into low frequency transformer, intermediate frequency transformer and high frequency transformer according to the working frequency. |
