西門子6SE70變頻器啟動就報F025故障分析；

西門子F025變頻器報故(gu)障，西門子維修6se70，6se70報F02故(gu)障維修解決方法和步驟(zou)如下：

1、檢查(cha)絕緣和接(jie)地(di)的情(qing)況。

2、西門子維修F025故(gu)障，檢查6se70的CUVC板的安裝。

3、西門子維(wei)修F025故(gu)障，檢查6se70的安全停車功能。

4、檢查(cha)工作(zuo)環境溫(wen)度是不是太高(gao)了。

5、檢測工作環境(jing)，灰塵是(shi)否(fou)過大。

6、中間直流環節(jie)的預(yu)充電電阻及(ji)電容是否(fou)存在問題。

7、檢查(cha)光纖維(wei)分(fen)配板(ban)及脈沖觸(chu)發(fa)板(ban)光纖連(lian)接(jie)的情況。

一般來說，可能(neng)是驅(qu)動板(ban)上(shang)的電(dian)容問題。如果(guo)逆變(bian)器報(bao)警F025，重新(xin)灌入CUVC參數不好使，就需要更換電(dian)源驅(qu)動板(ban)

得到處(chu)都(dou)是，主(zhu)回路(lu)(lu)兩個繼電(dian)(dian)(dian)(dian)器(qi)(qi)也爆(bao)開，主(zhu)控(kong)(kong)板(ban)暫(zan)時沒有(you)發(fa)現問題，但驅動部分燒了(le)(le)(le)好(hao)幾處(chu)，另外儲(chu)能(neng)大(da)(da)電(dian)(dian)(dian)(dian)容(rong)(rong)一部分都(dou)已發(fa)漲(zhang)，電(dian)(dian)(dian)(dian)容(rong)(rong)板(ban)上(shang)(shang)(shang)的(de)(de)兩顆大(da)(da)螺(luo)絲(si)接觸處(chu)全部燒焦，這(zhe)就是 420 系列變頻器(qi)(qi)的(de)(de)通病，因為(wei)所有(you)電(dian)(dian)(dian)(dian)量(liang)都(dou)是要(yao)(yao)(yao)經過這(zhe)兩顆鐵(tie)螺(luo)絲(si)，一旦鐵(tie)螺(luo)絲(si)生銹，很容(rong)(rong)易引起電(dian)(dian)(dian)(dian)容(rong)(rong)的(de)(de)充放電(dian)(dian)(dian)(dian)不(bu)良(liang)，這(zhe)樣電(dian)(dian)(dian)(dian)容(rong)(rong)發(fa)熱，漏電(dian)(dian)(dian)(dian)，發(fa)漲(zhang)到后(hou)(hou)損壞(huai)(huai)重要(yao)(yao)(yao)器(qi)(qi)件(jian)就不(bu)在話下(xia)了(le)(le)(le)，為(wei)了(le)(le)(le)防止再次(ci)接觸不(bu)良(liang)打火，在上(shang)(shang)(shang)螺(luo)絲(si)同時好(hao)焊上(shang)(shang)(shang)幾股粗銅線(xian)并存螺(luo)絲(si)位上(shang)(shang)(shang)好(hao)，維修(xiu)(xiu)觸發(fa)板(ban)時不(bu)知道(dao)參數的(de)(de)，可(ke)以從控(kong)(kong)制板(ban)上(shang)(shang)(shang)完(wan)好(hao)的(de)(de)器(qi)(qi)件(jian)與損壞(huai)(huai)相同的(de)(de)對比，修(xiu)(xiu)復該板(ban)的(de)(de)正向電(dian)(dian)(dian)(dian)壓為(wei) 4.7 伏，負(fu)向電(dian)(dian)(dian)(dian)壓為(wei) -4.44 伏，更換損壞(huai)(huai)器(qi)(qi)件(jian)后(hou)(hou)，可(ke)以加(jia)(jia)電(dian)(dian)(dian)(dian)試(shi)驗，試(shi)驗步驟按主(zhu)回路(lu)(lu)主(zhu)控(kong)(kong)制空載(zai)，負(fu)載(zai)分別運(yun)行檢查。 加(jia)(jia)電(dian)(dian)(dian)(dian)試(shi)驗前為(wei)保(bao)證器(qi)(qi)件(jian)安全，防止再次(ci)損壞(huai)(huai)重要(yao)(yao)(yao)器(qi)(qi)件(jian)，大(da)(da)容(rong)(rong)量(liang)暫(zan)時不(bu)要(yao)(yao)(yao)裝止，用兩只小(xiao)容(rong)(rong)量(liang)電(dian)(dian)(dian)(dian)容(rong)(rong)代替(ti)，為(wei)了(le)(le)(le)保(bao)護 IGBT ,電(dian)(dian)(dian)(dian)容(rong)(rong)到 IGBT 的(de)(de)供電(dian)(dian)(dian)(dian)回路(lu)(lu)好(hao)是串聯一保(bao)白熾燈泡(pao)，這(zhe)樣就可(ke)以加(jia)(jia)大(da)(da)電(dian)(dian)(dian)(dian)容(rong)(rong)了(le)(le)(le)，通電(dian)(dian)(dian)(dian)有(you)后(hou)(hou)如果顯示正常(chang)，可(ke)以啟(qi)動變頻器(qi)(qi)，再測量(liang) 6 個觸發(fa)市制脈沖，如果信號正常(chang)，就可(ke)以去掉電(dian)(dian)(dian)(dian)容(rong)(rong)與 IGBT 之間的(de)(de)燈泡(pao)，裝上(shang)(shang)(shang)大(da)(da)電(dian)(dian)(dian)(dian)容(rong)(rong)進行空載(zai)運(yun)行，正常(chang)后(hou)(hou)再接負(fu)載(zai)運(yun)行，經調試(shi)機(ji)器(qi)(qi)后(hou)(hou)一般(ban)恢復正常(chang)。
