叠铁芯和卷铁芯
Laminated core and coil core
一般均为叠铁芯，由铁芯叠装而成。卷铁芯的形式较多。渐开线铁芯的心柱与铁轭之间气隙较大，影响空载电流，所以容量不能做的太小；但因漏磁通垂直进入铁芯片平面，影响附加损耗，所以片宽不宜过大，即容量不能太大。
Generally, they are laminated iron cores, which are assembled by laminating iron cores. There are many forms of coil core. The air gap between the core pillar and yoke of the involute iron core is large, which affects the no-load current, so the capacity cannot be too small; however, because the leakage flux enters the iron chip plane vertically and affects the additional loss, the sheet width should not be too large, that is, the capacity cannot be too large.
铁心主要由铁芯本体、紧固件和绝缘件组成：
The core is mainly composed of iron core body, fasteners and insulating parts
①铁芯本体、磁导体、由电工钢片制成。
① The iron core body and magnetic conductor are made of electrical steel sheet.
②紧固件、夹件、螺杆、玻璃绑扎带、刚绑扎带和垫块等。
② Fasteners, clamps, screws, glass binding tape, rigid binding tape and cushion block, etc.
③绝缘件、夹件绝缘、绝缘管和绝缘垫、接地片和垫脚等。
③ Insulation parts, clamp insulation, insulation pipe and insulation pad, grounding plate and foot pad, etc.
