靜止式進相器工介紹

2021-08-13

靜止式進(jin)相器(qi)工(gong)作原理:電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動機運(yun)行時,靜態進(jin)相器(qi)與(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動機串(chuan)聯,運(yun)行時采集轉(zhuan)子(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)和同步(bu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓信號,經微處(chu)理器(qi)CPU處(chu)理后,將觸發信號發送給可控硅。交硅由可控硅組成。該方(fang)法是將工(gong)頻電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源轉(zhuan)換為與(yu)轉(zhuan)子(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)頻率相同的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源,并加(jia)入電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機轉(zhuan)子(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路,改變轉(zhuan)子(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)與(yu)轉(zhuan)子(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓的(de)(de)相位(wei)關(guan)系,通(tong)過磁(ci)場改變電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機定子(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)與(yu)定子(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓的(de)(de)相位(wei)關(guan)系,減小(xiao)了電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機的(de)(de)功率因(yin)數角,提高了電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機的(de)(de)功率因(yin)數。減小(xiao)定子(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu),降低電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機銅(tong)損(sun)、溫(wen)升,提高電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機過載能力,改善電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機運(yun)行狀態。

簡而(er)言(yan)之,照相機(ji)能像同(tong)步(bu)(bu)(bu)電(dian)機(ji)一樣,使電(dian)機(ji)處于準同(tong)步(bu)(bu)(bu)或亞同(tong)步(bu)(bu)(bu)狀態。盡(jin)管運行速度是同(tong)步(bu)(bu)(bu)的,但有點(dian)相似。同(tong)步(bu)(bu)(bu)機(ji)功(gong)率因數接近1,比異步(bu)(bu)(bu)電(dian)機(ji)節能。電(dian)動機(ji)由異步(bu)(bu)(bu)電(dian)動機(ji)變(bian)為同(tong)步(bu)(bu)(bu)電(dian)動機(ji),轉(zhuan)速恒(heng)定(ding),電(dian)機(ji)電(dian)流減小。

靜止式(shi)進(jin)(jin)相器的(de)變壓(ya)(ya)機(ji)和靜壓(ya)(ya)攝像機(ji),主要用(yong)(yong)于(yu)(yu)(yu)繞線電(dian)機(ji)。不(bu)同之(zhi)處在于(yu)(yu)(yu),變壓(ya)(ya)相機(ji)主要用(yong)(yong)于(yu)(yu)(yu)立(li)磨、軋機(ji)、穿孔機(ji)等(deng)負(fu)載(zai)電(dian)流(liu)不(bu)穩定,電(dian)流(liu)波動大,負(fu)載(zai)不(bu)平(ping)衡。靜止式(shi)進(jin)(jin)相器主要用(yong)(yong)于(yu)(yu)(yu)球磨機(ji)及其它負(fu)載(zai)穩定設備。

變載(zai)量進(jin)(jin)相器(qi)與(yu)靜(jing)態進(jin)(jin)相器(qi)的(de)(de)不同(tong)之處是,是可(ke)調負荷(he)進(jin)(jin)相器(qi)可(ke)以(yi)交替使用,靜(jing)止式進(jin)(jin)相器(qi)僅適用于負載(zai)較大(da)。相對于靜(jing)止相機而(er)言,變負荷(he)進(jin)(jin)入(ru)相機的(de)(de)內(nei)部結構要求更高(gao),電(dian)抗(kang)器(qi)和變壓器(qi)均為銅,可(ke)達(da)(da)到額定電(dian)流的(de)(de)3倍(bei)(bei)以(yi)上;在可(ke)控(kong)硅大(da)功率(lv)專業(ye)測試中(zhong),電(dian)流可(ke)達(da)(da)4倍(bei)(bei)以(yi)上;說到這里,控(kong)制(zhi)板是我公司的(de)(de)核心產品。變載(zai)進(jin)(jin)相機的(de)(de)使用效果及控(kong)制(zhi)板的(de)(de)選擇(ze)很重要,經過專業(ye)的(de)(de)測試,控(kong)制(zhi)板性能穩定。變載(zai)量進(jin)(jin)入(ru)攝像機,需要專業(ye)人員調試才能到達(da)(da)現(xian)場,根據負載(zai)情況,需臨(lin)時調整方案,直(zhi)至功率(lv)系(xi)數大(da)于0.95。
