抑制諧波

主(zhu)要(yao)是(shi)通過(guo)在電(dian)(dian)(dian)(dian)容補(bu)(bu)償(chang)回(hui)路中串(chuan)聯與之相(xiang)匹配的(de)(de)電(dian)(dian)(dian)(dian)抗(kang)器同時(shi)提高電(dian)(dian)(dian)(dian)容、開(kai)關的(de)(de)物理參(can)數，從(cong)而(er)有(you)效濾除電(dian)(dian)(dian)(dian)網中的(de)(de)部分(fen)諧(xie)波(bo)電(dian)(dian)(dian)(dian)流(liu)，一(yi)般30%左右(you)，另外電(dian)(dian)(dian)(dian)容合閘時(shi)不(bu)會產(chan)生(sheng)諧(xie)波(bo)電(dian)(dian)(dian)(dian)流(liu)放(fang)大，倒送(song)至電(dian)(dian)(dian)(dian)網加重(zhong)污(wu)染等問題(ti)，該(gai)方(fang)法(fa)既能(neng)有(you)效抑(yi)制(zhi)諧(xie)波(bo)，又能(neng)保證補(bu)(bu)償(chang)設(she)備正常工作。此種(zhong)諧(xie)波(bo)治理方(fang)法(fa)是(shi)目前Z經濟也是(shi)Z常用的(de)(de)有(you)效方(fang)法(fa)，但是(shi)在諧(xie)波(bo)污(wu)染較為嚴重(zhong)的(de)(de)情況(kuang)下(xia)，此種(zhong)方(fang)法(fa)不(bu)能(neng)從(cong)根(gen)源上(shang)徹(che)底解決諧(xie)波(bo)污(wu)染狀況(kuang)，這種(zhong)情況(kuang)下(xia)就需要(yao)安裝(zhuang)濾波(bo)器。

無源濾波器

本產品采用智能無(wu)功(gong)(gong)(gong)(gong)控制技術來(lai)實現濾(lv)(lv)波(bo)補償回路的(de)自動(dong)控制投(tou)切。濾(lv)(lv)波(bo)補償回路由濾(lv)(lv)波(bo)電容器(qi)和濾(lv)(lv)波(bo)電抗(kang)器(qi)組成，對(dui)諧(xie)波(bo)形成低阻抗(kang)，讓(rang)諧(xie)波(bo)流(liu)入濾(lv)(lv)波(bo)器(qi)；同時在基波(bo)產生無(wu)功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率進行補償；從而(er)達到諧(xie)波(bo)治理和補償無(wu)功(gong)(gong)(gong)(gong)提高功(gong)(gong)(gong)(gong)率因數(shu)的(de)雙重效果。

該裝置(zhi)是針對用戶(hu)配(pei)電(dian)(dian)系統實際情(qing)況(kuang)而專門設計的(de)(de)，廣泛應用于(yu)電(dian)(dian)網中非線性負荷的(de)(de)領域(yu)，如整(zheng)流、變(bian)頻調速(su)、中頻加熱、冶金電(dian)(dian)解、化(hua)學電(dian)(dian)解、光伏產(chan)(chan)業等(deng)電(dian)(dian)力電(dian)(dian)子設備(bei)的(de)(de)工業領域(yu)；電(dian)(dian)氣化(hua)鐵道、地下鐵道、無規(gui)電(dian)(dian)車等(deng)交通領域(yu)；廣播、郵政、通訊、對諧波(bo)干擾敏感的(de)(de)IT產(chan)(chan)業領域(yu)；以及對電(dian)(dian)能質量要求嚴(yan)格的(de)(de)會展中心、商業大廈等(deng)場所 。

有源濾波器

有(you)源電(dian)力濾(lv)(lv)波(bo)(bo)裝(zhuang)置(zhi)的基(ji)本(ben)原理(li)是從電(dian)網(wang)中檢(jian)測出諧(xie)(xie)波(bo)(bo)電(dian)流(liu)，經內(nei)部(bu)芯片快速計算、分析、比較，控制主(zhu)功(gong)(gong)率單(dan)元產(chan)生一個(ge)與該(gai)諧(xie)(xie)波(bo)(bo)電(dian)流(liu)大小相(xiang)等而極性(xing)相(xiang)反的補(bu)(bu)償(chang)電(dian)流(liu)，從而使電(dian)網(wang)電(dian)流(liu)只含基(ji)波(bo)(bo)成分。這種濾(lv)(lv)波(bo)(bo)器能(neng)對頻率和幅值都變(bian)化的諧(xie)(xie)波(bo)(bo)進行跟蹤補(bu)(bu)償(chang)，且補(bu)(bu)償(chang)特性(xing)不受電(dian)網(wang)阻抗(kang)的影(ying)響。該(gai)有(you)源電(dian)力諧(xie)(xie)波(bo)(bo)濾(lv)(lv)波(bo)(bo)裝(zhuang)置(zhi), 引進美國 TMS320F2812 芯片，根(gen)據最(zui)新的瞬時無功(gong)(gong)功(gong)(gong)率理(li)論，應(ying)用數字信號(hao)處理(li)技(ji)(ji)(ji)術(shu)(shu)（DSP），脈寬調制技(ji)(ji)(ji)術(shu)(shu)（PWM），智(zhi)能(neng)化功(gong)(gong)率單(dan)元技(ji)(ji)(ji)術(shu)(shu)（IPM），觸摸屏技(ji)(ji)(ji)術(shu)(shu)（GP）等前沿科技(ji)(ji)(ji)，可實現動(dong)態消(xiao)除諧(xie)(xie)波(bo)(bo)，平(ping)衡三(san)相(xiang)負(fu)荷，是一種高技(ji)(ji)(ji)術(shu)(shu)含量，濾(lv)(lv)波(bo)(bo)效率最(zui)理(li)想諧(xie)(xie)波(bo)(bo)治理(li)和無功(gong)(gong)補(bu)(bu)償(chang)產(chan)品。
