項目介紹

河南(nan)豐博天瑞水(shui)泥(ni)有限公(gong)司成立于2006年(nian)，是(shi)衛輝市人民政府招商引資的股份制(zhi)企(qi)業。公(gong)司注(zhu)冊資金1000萬元，二期投資5500萬，總(zong)投資8500多萬元，年(nian)生(sheng)產水(shui)泥(ni)200萬噸。公(gong)司位(wei)于衛輝市唐莊鎮代莊村東，位(wei)于省道226翟(zhai)陽線(xian)上，北鄰省道306衛柿線(xian)，南(nan)鄰107國道，交通(tong)十分便利。

 水泥(ni)(ni)行業普遍存在現場工況環境惡劣，主(zhu)(zhu)(zhu)要是(shi)現場粉塵太(tai)多，對設備的(de)(de)要求也相(xiang)對較高。電(dian)(dian)網質量相(xiang)對較差，沒有很好的(de)(de)電(dian)(dian)網容量。電(dian)(dian)機(ji)(ji)的(de)(de)選用大(da)多為繞線式(shi)電(dian)(dian)機(ji)(ji)。水泥(ni)(ni)磨主(zhu)(zhu)(zhu)電(dian)(dian)機(ji)(ji)、原料磨主(zhu)(zhu)(zhu)電(dian)(dian)機(ji)(ji)、煤立磨主(zhu)(zhu)(zhu)電(dian)(dian)機(ji)(ji)、礦山破(po)碎電(dian)(dian)機(ji)(ji)、砂巖破(po)碎電(dian)(dian)機(ji)(ji)、輥(gun)壓(ya)機(ji)(ji)主(zhu)(zhu)(zhu)電(dian)(dian)機(ji)(ji)。對于水泥(ni)(ni)行業這些重(zhong)載電(dian)(dian)機(ji)(ji)的(de)(de)起動。

豐博天瑞(rui)水泥長根據實際工況可采用了我公司YRQ水電阻繞線式軟起動器+LP系列靜止式進相器，對進行電機的軟起動和功率補償。LP采用的是微計算機控制理論和交-交變頻技術。

靜止式進相器投入使用后：

1、電機起(qi)動(dong)電流：Iq≤1.3Ie。

2、起動時(shi)間(jian)調節范圍：13-45S可(ke)調。

3、母線壓(ya)降：小(xiao)于5%;并在電(dian)網允許的情況(kuang)下大限(xian)度地減小(xiao)起動時的電(dian)網壓(ya)降，穩定(ding)電(dian)網質(zhi)量。

4、進(jin)相(xiang)后(hou)使(shi)交流繞線(xian)式異步電動(dong)機的功(gong)(gong)(gong)率因數達(da)到0.96，無功(gong)(gong)(gong)功(gong)(gong)(gong)率下降60%以(yi)上，提高負載(zai)的過載(zai)能(neng)力(li)和電機效率。

對水(shui)泥磨(mo)主電機(ji)(ji)(ji)、原料磨(mo)主電機(ji)(ji)(ji)、煤立(li)磨(mo)主電機(ji)(ji)(ji)、礦(kuang)山破(po)碎(sui)電機(ji)(ji)(ji)、砂(sha)巖破(po)碎(sui)電機(ji)(ji)(ji)、輥壓機(ji)(ji)(ji)主電機(ji)(ji)(ji)等電機(ji)(ji)(ji)的重載起到明顯的作(zuo)用。

水(shui)電(dian)(dian)(dian)(dian)阻(zu)起(qi)動(dong)柜串接于電(dian)(dian)(dian)(dian)動(dong)機的轉(zhuan)子(zi)回路(lu)中，變轉(zhuan)子(zi)電(dian)(dian)(dian)(dian)阻(zu)起(qi)動(dong)。轉(zhuan)子(zi)回路(lu)增加(jia)適當電(dian)(dian)(dian)(dian)阻(zu)值以后(hou)，一方面減小了起(qi)動(dong)電(dian)(dian)(dian)(dian)流(liu)，另一方面可增大起(qi)動(dong)轉(zhuan)矩，從而縮短起(qi)動(dong)時(shi)間，減少了電(dian)(dian)(dian)(dian)動(dong)機的發(fa)熱。

水電(dian)阻(zu)啟(qi)動(dong)柜投入使用后(hou)：

1、實現軟起動(dong)(dong)，起動(dong)(dong)電阻由初始值(zhi)(zhi)逐漸連(lian)續變化減小，直至為零，保(bao)證電機(ji)平滑(hua)起動(dong)(dong)，無機(ji)械(xie)沖擊(ji)，無二(er)次(ci)峰值(zhi)(zhi)電流沖擊(ji)。

2、起動電流(liu)可控制(起動過程可控制)根據(ju)負載實際工況，通過調整，配置電液(ye)的濃度來改變電阻值的大小。

3、起(qi)動(dong)(dong)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)小于3倍的電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機額定定子(zi)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)。由(you)于熱(re)變水電(dian)(dian)(dian)(dian)(dian)(dian)阻為純電(dian)(dian)(dian)(dian)(dian)(dian)阻特性，無感(gan)性元件，起(qi)動(dong)(dong)器(qi)本身不會(hui)引起(qi)電(dian)(dian)(dian)(dian)(dian)(dian)網功率因數(shu)(shu)降(jiang)低，所以，它(ta)相對于電(dian)(dian)(dian)(dian)(dian)(dian)抗器(qi)起(qi)動(dong)(dong)器(qi)、自耦降(jiang)壓起(qi)動(dong)(dong)器(qi)等感(gan)性設備來說，起(qi)動(dong)(dong)時(shi)功率因數(shu)(shu)較高(gao)，必然起(qi)動(dong)(dong)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)比它(ta)們小。

4、起(qi)(qi)動時(shi)母(mu)線壓降(jiang)低。由(you)于起(qi)(qi)動電流比(bi)電抗(kang)器等其(qi)它起(qi)(qi)動設備(bei)顯(xian)著減(jian)小，所以起(qi)(qi)動壓降(jiang)〈10%Ue，對其(qi)它設備(bei)影響(xiang)小。

5、起動過程無諧(xie)波污(wu)染，起動轉矩(ju)大(da)。由(you)于熱變水電阻本身(shen)無感性特性，近似純電阻，因此(ci)，具有起動功(gong)率因數(shu)高，起動轉矩(ju)大(da)。
