概述 / Product overview
大容量可调电抗器在电力系统中的应用十分广泛，如动态无功补偿、 The application of large capacity adjustable reactor in power system is
线路调压、自动消弧线圈、电机降压软起动、谐振试验变压器等。过 very wide, such as dynamic reactive power compensation, line voltage
去由于电抗器电感连续可调技术未能取得实用性的突破，所以只能用 regulation, automatic arc suppression coil, motor voltage reducing soft
start, resonant test transformer, etc.. Due to the continuously adjustable
抽头或分组有级调感来代替，而随后发展起来的利用电力电子技术控 reactor technology failed to achieve practical breakthrough, we can only
制的相控电抗器（TCR）虽然也能连续调节流过固定电抗器的感性电 use tap or packet level adjustment to replace, and then developed using
流，但其原理是通过可控硅斩波来实现电流调节的，不可避免地带来 phase controlled reactor power electronic control technology (TCR)
电流波形的畸变的问题，加上其所使用的空心电抗器由于容量大，存 although the inductive current can flow through continuous adjustment of
在占地面积大，电磁辐射严重的缺点，因此，可调电抗器在电力系统 fixed reactor, but the principle is controlled by adjust the current silicon

的应用由于受到技术的制约而得不到推广应用。 hollow reactor due to large capacity, in an area of large electromagnetic
近年来，随着可控电抗器技术的不断发展，一种新型磁控可调电抗器 radiation serious shortcomings, therefore, the adjustable reactor application
（MCR）的问世使得电力系统许多需要可控电抗器的场合得到了推广 in electric power system due to restricted technology rather than application.
In recent years, with the continuous development of controllable reactor
使用的可能。MCR 型电抗器是通过直流偏磁改变铁心电抗器铁心的 technology, a new type of magnetically controlled reactor (MCR) has been
磁导率来实现电感可调的，其技术突破的关键是直流偏磁只使铁心的 developed, which makes it possible to promote the use of power system in
局部小区域饱和而不是整个铁心饱和，饱和的小截面铁心就相当于固 many occasions. MCR type reactor is to realize adjustable inductance by DC
定电感电抗器的气隙，当饱和度改变时，等效气隙的宽度也相应改变， magnetic bias change permeability of core reactor core, the key technical
从而实现电感可调。局部饱和技术的引入，使得 MCR 可控电抗器的 breakthrough is the core of the DC magnetic bias only local area rather than
the saturation saturation, small section saturation air gap is equivalent to the
损耗比、噪音、谐波含量等主要几项指标得以大幅提高。 fixed inductance of reactor, when the saturation change. The equivalent width
of the gap is also changed accordingly, so as to realize adjustable inductance.
The introduction of local saturation technique makes the loss ratio, noise and
harmonic content of MCR controllable reactor can be improved significantly.
