■産品概述product overview

現(xiàn)代電(diàn)力電(diàn)子(zǐ)設備的(de)大(dà)量使用(yòng)産生(shēng)的(de)非線性電(diàn)流正以諧波方式影(←yǐng)響電(diàn)網并加重電(diàn)網污染，并導緻電(diàn)容器(qì)，變壓器(qì)及✔傳輸設備過載并故障，對(duì)測量，傳動，計(jì)算(suàn)等設備産生(shēng)的(de)嚴重幹擾，諧振及電(diàn)壓畸變還(hái)造成供電(diàn)事(shì)故。串•聯電(diàn)抗器(qì)可(kě)得(de)以改善與避免。電(diàn)容器(qì)串聯電(diàn)抗器(qì)後諧振頻(pín∞)率低(dī)于系統最低(dī)(一(yī)般為(wèi)5次及7次),使其在工(gōng)頻(pín)下(xià)呈容性，以改善功率§因數(shù)，而在諧振并無放(fàng)大(dà)諧波之濾，良好(hǎo)的(de)阻抗匹配後，電(diàn)容器(qì)組可(kě)吸收諧波電(diàn)流(如(rú)5次)30§%-60%。

The extenslve use of modern power electronic devices generates nonlinear currentsthat $affect thepower grid in a harmonic manner,exacerbating grid po'llutionand causing overload and fallure ofcapacltors↔,transformers,and transmlssion equipment.This causes serious in≤terference,resonance,and voltage distortlon to measurement,©transmisslon,calculation,and otherequlpment,leading to power supply accidents.Serles re€actors can be Improved and avolded.After connectlng capacltors in serles with reactors,'the resonant frequency ls lower than thelowestin the system (usually 5th and 7th),making It ¥capacltlve at power frequency to lmprove powerfactor.In resonance>,there ls no fitering of amplfied harmonics,and after good impedancematching,thecapacltor ®bank can absorb 30%-60%ofharmonlccurrent(such as 5th).
