(十)变压器实验系列变压器在实际生产和生活中有广泛的应用。上海科教版等教材专门安排了一章《电能的输送与变压器》内容。《高中物理课程标准》要求“通过分组实验,探究变压器电压与匝数的关系”,“了解从变电站到住宅的输电过程,知道远距离输电时应用高电压的道理”;并建议 (X) Transformer Experimental Series Transformer in the actual production and life has a wide range of applications. Shanghai Science Education Edition and other textbooks specifically arranged a chapter “power transmission and transformer” content. The “High School Physics Curriculum Standard” requires that “the relationship between transformer voltage and the number of turns be explored by grouping experiments”, “understand the transmission process from substation to house and know the truth about the application of high voltage in long-distance transmission”; and suggest
