  线绕式低压串联电抗器

  Wire wound type low voltage series-connected reactor

  产品概述:

  干式铁芯串联电抗器用于低压无功补偿柜中,与电容器相串联,当低压电网中有大量整流、变流装置等谐波源时,其产生的高次谐波会严重危害主变及其它电器设备的安全运行。电抗器与电容器相串联后,能有效地吸收电网谐波,改善系统的电压波形,提高系统的功率因数,并能有效的仰制合闸涌流及操作过电压,有效地保护电容器。

  The dry type iron core series-connected reactor used in low voltage reactive power compensating cabinet,series-connected with capacitor,when the low voltage system has large loads such as rectifier,conversion device and etc other appliances with harmonic waves,they will produce high harmonic waves and do harm to other electric equipments.After the reactor series connected with capacitors with harmonic waves,they will produce high harmonic waves and do harm to other electric equipments,After the reactor series connected with capacitors,it can effectively absorb the harmonic waves,improve the voltage wave,and power factor,and eliminate the surging and operating over-voltage,protect the capacitor.

  结构特征

  1. 该电抗器分为三相和单相两种,均为铁芯干式;

  2. 铁芯采用优质损耗冷轧取向硅钢片,芯柱由多个气隙分成均匀小段,气隙采用为环氧层压玻璃布扮作间隔,以保证电抗气隙在运行过程中不发生变化。

  3. 线圈采用H级漆包扁铜线绕制,排列紧密且均匀,具有极佳的散热性功能;

  4. 电抗器的线圈的铁芯组装成一体经过预烘→真空浸漆→热烘固化这一工艺流程,采用H级浸漆,使电抗器的线圈和铁芯牢固的结合在一起,不但大大减小了运行时的噪音,而且具有极高的耐热等级;

  5. 电抗器芯柱部分紧固件采用无磁性材料,确保电抗器具有较高的品质因数和较低的温升;

  6. 外露部件采取了防腐处理,引出了端子采用镀锡铜管端子。

  1. The reactor has three-phase and single phase type, all of iron core dry type.

  2.The iron made of high quality low loss cold rolled oriented silicone steel sheet,core column consists of multiple gas gap,divided evenly into many small sections,gap isolated by use of epoxy resin layer pressed glass cloth,this can ensure the gap have no change during in service.

  3. Coil made of H class or C class enamelled copper flat wire, laid closely and evenly, where it has perfect heat radiating performance.

  4.After the core and coil are integrated together,then pre-dry,immerse into painting in vacuum chamber heat dry for solidification,H class paint used for immersion,this can solidly condense the coil and iron coil,which will reduce the noise level in service and has high heat proof class.

  5. The fixing parts of core column adopted non-magnetic material to ensure its high quality and low temperature rise.

  6. Exposed surface treat for corrosion resistant, output sides utilize tinned copper pipe terminals.
