Abstract

本实用新型涉及电抗器,尤其是带有磁环的电抗器,包括由绕组(3)和铁心(2)组成的本体,以及安装在本体上的接线端子(4),其特点是,在所述本体外套装有由导磁材料制成的磁环(1),该磁环(1)由两个相同的半环组成,每个半环均为只有一端封闭的管状,该两个半环分别与铁心(2)的两端接触。本实用新型的电抗器不仅能够克服电抗器制作过程中存在的技术缺陷,而且电抗器有良好的屏蔽作用、抗铁心饱和及较低的磁导率。经实验证明,将磁环应用在电抗器上,可提高电抗器的铁心抗饱和性能,增强屏蔽,从而符合技术指标的要求,提高电抗器的使用性能。

Description

带有磁环的电抗器
技术领域
本实用新型涉及电抗器,尤其是带有磁环的电抗器。
背景技术
随着经济的发展,电抗器在各个领域的应用已日趋广泛,电抗器具有滤波、整流、保护电路等作用,它能够维护电路正常稳定的工作。尤其是一些有特殊用途的电抗器对磁导率、屏蔽、抗铁心饱和都有较高的技术要求。为了避免铁心饱和,需要在铁心上开气隙,而气隙附近会有磁场扩散现象,扩散的磁场会产生附加的损耗,特别是在单个气隙尺寸较大的时候,会在气隙附近的铁心和绕组上产生非常严重的附加损耗。如果不加限制,这种附加损耗会使得电抗器的损耗增加一倍以上。为了减少这种不必要的附加损耗,在制造工艺上往往需要增加气隙的数量,减小单个气隙的尺寸,这样就会影响电抗器的外形。
实用新型内容
本实用新型的目的之一是提供一种屏蔽作用良好、抗铁心饱和及具有较低磁导率的带有磁环的电抗器。
为实现上述目的,本实用新型采用的技术方案是:
一种带有磁环的电抗器,包括由绕组和铁心组成的本体,以及安装在本体上的接线端子,其特别之处在于,在所述本体外套装有由导磁材料制成的磁环,该磁环由两个相同的半环组成,每个半环均为只有一端封闭的管状,该两个半环分别与铁心的两端接触。
其中在每个半环上均开有供接线端子伸出的槽。
进一步的,其中每个半环的侧面和底面相交处均有倒角。
进一步的,其中磁环为铁氧体或铁硅铝材料。
本实用新型的电抗器不仅能够克服电抗器制作过程中存在的技术缺陷,而且电抗器有良好的屏蔽作用、抗铁心饱和及较低的磁导率。经实验证明,将磁环应用在电抗器上,可提高电抗器的铁心抗饱和性能,增强屏蔽,从而符合技术指标的要求,提高电抗器的使用性能。
附图说明
附图1为本实用新型中半环的结构示意图;
附图2为本实用新型的结构示意图。
具体实施方式
如图1所示,本实用新型的电抗器,包括由绕组3和铁心2(不是“铁芯”,具体可参见现行国家标准GB 19212.1-2003的34、62、83等页)组成的本体,以及安装在本体上的接线端子4,在本体外套装有由导磁材料制成的磁环1,该磁环1由两个相同的半环组成,每个半环均为只有一端封闭的管状,该两个半环分别与铁心2的两端接触。另外在每个半环上均开有供接线端子4伸出的槽,并且每个半环的侧面和底面相交处均倒角。磁环1采用铁氧体或铁硅铝等导磁材料。
