Description

一种变压器铁芯
本实用新型涉及一种变压器铁芯。
现有的变压器铁芯的结构形式主要有四种,分别是EI型、CD型、环型和R形。
EI型铁芯由于是由无数硅钢片叠合而成,因此使得铁芯的磁路中有较大的气隙,用此种铁芯制成的变压器效率低、漏磁大,在电子设备中产生电磁干扰而污染电源。CD型铁芯虽然较好地解决了磁路中的气隙问题,但铁芯制造复杂,精度要求高。
无气隙的环型铁芯虽具有连续不断的磁路,且过载能力强,但由于截面呈矩形,边角比较突出,造成比较大的漏磁;无气隙的R型铁芯截面接近圆形,解决了环型铁芯的上述弱点,但其外形为矩形,使得铁芯的制造成本高,而且此种铁芯需配备专用的骨架,从而增加了变压器的制造成本。
本实用新型的发明目的在于提供一种具有连续不断的磁路的、漏磁少、制造成本低的变压器铁芯。
本实用新型是这样实现的,包括一条高磁通密度的硅钢带,特别之处在于硅钢带紧密卷绕成圆环状或椭圆环状,硅钢带的形状呈有规则的中间大,两端细小状,使硅钢片叠合而成的的变压器铁芯的截面呈圆形或椭圆形。
本实用新型与以有技术相比,具有连续不断的磁路、漏磁少、无需骨架及支架、安装简便、成本低、重量轻的优点,无需骨架,漆包线绕组可均匀分布在整个铁芯的表面,且紧帖铁芯,使电磁耦合更好,而且漆包线绕组匝长可减少10%左右,亦可选用更粗的漆包线,使绕组内阻更低。
图1为本实用新型的结构示意图;
图2为硅钢片的示意图;
图3为本实用新型的截面视图。
现结合附图和实施例对本实用新型作进一步详细描述:
如图1所示,本实用新型是由一条高磁通密度的硅钢带紧密卷绕成圆环状(如图1a所示)或椭圆环状(如图1b所示),如图2所示,硅钢带的形状呈有规则的中间大,两端细小状,使硅钢片叠合而成的的变压器铁芯的截面呈圆形(如图3a所示)或椭圆形(如图3b所示)。
