产品概述 Product Overview

该系列低压串联电抗器用于低压无功补偿装置中，与电容器相串联，当低压电网中有大量整流，变流转正等谐波源时，其生产的高次谐波会严重危害主变及其他电器设备的安全运行。电抗器与电容器相串联后，能有效的抑制谐波放大，改善系统的电压波形，提高系统的功率因数，并能有效地抑制合闸涌流及操作过电压，有效的保护了电容器。

This series of low-voltage series reactor is used in lowvoltage reactive power compensation device and connected in series with capacitor phase. When there are a large number of harmonic sources in low-voltage power grid such as rectifier and converter, the high harmonics produced by them will seriously endanger the safe operation of main transformer and other electrical equipment. Reactors in series with capacitors can effectively suppress harmonic amplification, improve the voltage waveform of the system, increase the power factor of the system, and effectively suppress the closing surge and operating overvoltage, effectively protecting the capacitors.

主要特点 Main features

◇ 该电抗器分为三相和单相两种，均为铁芯干式；

◇ 铁芯采用低损耗冷轧取向硅钢片，芯柱由多个气隙分成均匀小段，气隙采用环氧层压玻璃布板作间隔，以保证电抗气隙在运行过程中不发生变化；

◇ 线圈采用H 级漆包扁铜线绕制，排列紧密且均匀，具有不错耐热性能；

◇ 电抗器的线圈和铁芯组装成一体后经过预烘——真空浸漆——热烘固化这一工艺流程，采用H 级浸渍漆，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，而且具有很高的耐热等级；

◇ 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；

◇ 外露部队年均采取了防腐蚀处理，收出端子采用镀锡铜管端子。

◇ The reactor is divided into two kinds: three-phase and single-phase, both of which are iron core dry type.

◇ The core adopts high-quality low-loss cold-rolled oriented silicon steel sheet, and the core column is divided into uniform small sections by multiple air gaps, and the air gaps are spaced by epoxy laminated glass cloth plates to ensure that the reactance air gaps do not change during operation.

◇ The coil is wound with H-grade enameled flat copper wire, which is closely and evenly arranged and has excellent heat resistance.

◇ After the coil and core of reactor are assembled together, they go through the process of pre-baking - vacuum dipping lacquer-hot baking and curing, and H-grade impregnating lacquer is used to make the coil and core of reactor firmly combined, which not only greatly reduces the noise during operation, but also has a very high grade of heat resistance.

◇ The fasteners in the core column part of the reactor are made of non-magnetic materials, ensuring that the reactor has a high quality factor and a low temperature rise.

The exposed forces are treated with anti-corrosion treatment, and tinned copper tube terminals are used for the receiving and discharging terminals.
