Abstract

一种六柱斜角椭圆形铁心磁控电抗器,采用六个主铁心柱一字排开,与上下铁轭铁心连成一体,主铁心心柱和上下铁轭铁心接缝为斜接缝,上下铁轭铁心与主铁心心柱为多级阶梯状截面,截面为椭圆形。由于此独特的铁心结构,使得六柱斜角椭圆形铁心磁控电抗器的线圈上连接的可控硅在电源电压的一个周期里分别触发导通,从而通过上下铁轭为控制磁通提供流通回路,使工作主铁心柱磁饱和。通过调节可控硅导通角,可以改变直流控制电流的大小和相应的铁心磁饱和度,从而使得电抗器的容量能够连续可调。此结构不用提供直流电源就可对电抗器直接调节,操作方便,设备简单化,经济效益比较显著。

Description

一种六柱斜角椭圆形铁心磁控电抗器
技术领域
本实用新型涉及一种电网中电力设备,具体涉及一种电抗器。
背景技术
电抗器是电网运行中进行无功补偿的常用电气设备。目前使用的容量可调的电抗器多为磁控电抗器,这种电抗器使用可控硅来控制电抗器调节容量,一般是外加直流电源,而且外加直流励磁系统其伏安特性呈明显的非线性,使得电抗器输出变化较大。
实用新型内容
本实用新型针对现有电抗器存在的缺陷,提出一种不用提供直流电源,操作调节方便、结构简单的电抗器。
技术方案
本实用新型解决其技术问题所采用的技术方案是:一种六柱斜角椭圆形铁心磁控电抗器,其特征是:六个主铁心柱一字排开,与上下铁轭连接成一体,主铁心柱与上下铁轭铁心接缝为斜接缝,上下铁轭铁心与主铁心柱为阶梯状多级截面,截面为椭圆形。
本实用新型的有益效果
由于此独特的铁心结构,使得六柱斜角椭圆形铁心磁控电抗器的线圈上连接的可控硅在电源电压的一个周期里分别触发导通,从而通过上下铁轭为控制磁通提供流通回路,使工作主铁心柱磁饱和。通过调节可控硅导通角,可以改变直流控制电流的大小和相应的铁心磁饱和度,从而使得电抗器的容量能够连续可调。此结构不用提供直流电源就可对电抗器直接调节,操作方便,设备简单化,经济效益比较显著。
附图说明:
下面结合附图和实施方式对本实用新型进一步说明。
图1为本实用新型结构示意图。
图2为1的俯视图。
图3为图1的A-A视图。
图4为图1的B-B视图。
具体实施方式
一种六柱斜角椭圆形铁心磁控电抗器,其电抗器铁心结构为六柱结构,如图1所示。六个主铁心柱1采用一字排开,与上下铁轭铁心连接成一体,主铁心柱1与上铁轭铁心2及下铁轭铁心3接缝为斜接缝。电抗器的六个线圈分别套在六个主铁心柱上,按常规方式通过外部引线连接可控硅和二极管,构成控制线路。
铁心心柱采用六柱铁心,主铁心柱为多级阶梯状,截面为椭圆形,如图3所示。上下铁轭铁心为多级阶梯状,截面级为椭圆形,如图4所示。上下铁轭的横截面要比铁心心柱的横截面大,一方面满足正常的交流磁路,另一方面满足控制的直流回路,以致于使上下铁轭铁心不饱和。
