充電機的現狀
    目前,礦用電(dian)(dian)(dian)機車蓄(xu)電(dian)(dian)(dian)池(chi)的(de)充(chong)(chong)電(dian)(dian)(dian),無論是恒流(liu)(liu)充(chong)(chong)電(dian)(dian)(dian)、恒壓(ya)充(chong)(chong)電(dian)(dian)(dian)或是先恒流(liu)(liu)再恒壓(ya)的(de)分段(duan)式充(chong)(chong)電(dian)(dian)(dian),都(dou)有(you)一個共(gong)同(tong)的(de)問題,就是這(zhe)種小(xiao)電(dian)(dian)(dian)流(liu)(liu)慢充(chong)(chong)方式,蓄(xu)電(dian)(dian)(dian)池(chi)初充(chong)(chong)需(xu)70小(xiao)時以上(shang),進行普通充(chong)(chong)電(dian)(dian)(dian)也需(xu)10小(xiao)時以上(shang),這(zhe)種充(chong)(chong)電(dian)(dian)(dian)方式在(zai)充(chong)(chong)電(dian)(dian)(dian)過(guo)程的(de)初期,充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)遠小(xiao)于蓄(xu)電(dian)(dian)(dian)池(chi)可(ke)(ke)接受的(de)充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu),因(yin)而(er)拉長(chang)了充(chong)(chong)電(dian)(dian)(dian)時間,造(zao)成電(dian)(dian)(dian)能(neng)的(de)浪費。而(er)在(zai)充(chong)(chong)電(dian)(dian)(dian)過(guo)程的(de)后期,充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)又大于蓄(xu)電(dian)(dian)(dian)池(chi)可(ke)(ke)接受的(de)電(dian)(dian)(dian)流(liu)(liu),蓄(xu)電(dian)(dian)(dian)池(chi)內部溫度升高,產生(sheng)大量(liang)析(xi)氣(qi),并形成內部硫化結(jie)晶(jing),大大縮(suo)短了蓄(xu)電(dian)(dian)(dian)池(chi)的(de)循環(huan)(huan)使用壽命,甚至有(you)可(ke)(ke)能(neng)永久性地損壞電(dian)(dian)(dian)池(chi)。這(zhe)不僅造(zao)成了浪費,也增加了對(dui)環(huan)(huan)境的(de)污染。同(tong)時,這(zhe)種傳(chuan)統充(chong)(chong)電(dian)(dian)(dian)機采用變壓(ya)器變壓(ya)整流(liu)(liu),可(ke)(ke)控硅控制的(de)途徑,技術落后,設備笨重,可(ke)(ke)靠性也差。
    美國科學家馬(ma)斯通過對(dui)鉛(qian)酸(suan)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)大(da)量試驗(yan)研究(jiu),提(ti)出(chu)了一條鉛(qian)酸(suan)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)可接受的(de)(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)曲線(xian)。在充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)過程的(de)(de)(de)初(chu)期(qi),蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)可接受的(de)(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)很大(da)。隨著充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)過程的(de)(de)(de)延續,充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)逐(zhu)漸按(an)(an)指數規律減(jian)小。讓充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機的(de)(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)按(an)(an)這(zhe)樣一條理(li)想電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)曲線(xian)變化(hua),就可以(yi)最大(da)限(xian)度(du)(du)的(de)(de)(de)提(ti)高(gao)(gao)(gao)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)效(xiao)率。同時,試驗(yan)表明(ming),采用脈沖(chong)式的(de)(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)方式是(shi)消除各種極(ji)化(hua)現象,提(ti)高(gao)(gao)(gao)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)速度(du)(du),延長蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)循環使用壽命的(de)(de)(de)有(you)效(xiao)途徑。這(zhe)種充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)方式是(shi)在對(dui)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)過程中(zhong)適(shi)時暫停充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian),并適(shi)當加(jia)入放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)脈沖(chong)。當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)停止時,電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)歐姆極(ji)化(hua)消失(shi),濃差極(ji)化(hua)和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)化(hua)學極(ji)化(hua)減(jian)弱。若能(neng)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)過程中(zhong)讓其(qi)反向放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian),則極(ji)化(hua)現象迅(xun)速消失(shi),電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)內(nei)部溫度(du)(du)也(ye)會因放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)而(er)得到有(you)效(xiao)控(kong)制(zhi)。脈沖(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)充(chong)(chong)放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)極(ji)板(ban)有(you)加(jia)強其(qi)韌性(xing)的(de)(de)(de)效(xiao)果,可以(yi)大(da)大(da)提(ti)高(gao)(gao)(gao)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)循環使用壽命。同時,由(you)于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)極(ji)化(hua)現象的(de)(de)(de)消失(shi),脈沖(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)又可以(yi)深層次地激活電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)內(nei)部的(de)(de)(de)活性(xing)物質,從而(er)大(da)幅度(du)(du)提(ti)高(gao)(gao)(gao)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)有(you)效(xiao)容量。
    當前,帶有自適應控制技術的脈沖式充電機已成為礦用電機車充電機的主要發展方向。因此,開發新一代的智能快速充電機不僅可以提高充電效率,降低使用單位的運營成本,同時也具有節能、環保等諸方面的社會意義。上(shang)海施能電器(qi)設備(bei)有限公司始(shi)建于1984年(nian),上海市高新技術企業,中國工業車輛優秀配套供應商,上海電器行業名優產品,主要生產工頻系列充電機,高頻系列充電機,鋰電池充電機系列放電機系列充放電機等電器產品。
