充電機的現狀
    目前(qian)，礦用電(dian)(dian)(dian)機車(che)蓄(xu)電(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)，無論是(shi)恒流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)、恒壓(ya)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)或是(shi)先恒流(liu)再恒壓(ya)的(de)(de)(de)(de)(de)分段式(shi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)，都有一個共同的(de)(de)(de)(de)(de)問題，就是(shi)這(zhe)(zhe)種(zhong)小電(dian)(dian)(dian)流(liu)慢充(chong)(chong)(chong)(chong)方式(shi)，蓄(xu)電(dian)(dian)(dian)池(chi)(chi)初充(chong)(chong)(chong)(chong)需(xu)70小時以上，進行普通充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)也需(xu)10小時以上，這(zhe)(zhe)種(zhong)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)方式(shi)在充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)過程的(de)(de)(de)(de)(de)初期，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)遠小于蓄(xu)電(dian)(dian)(dian)池(chi)(chi)可接(jie)受(shou)的(de)(de)(de)(de)(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)，因而(er)拉長了(le)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)時間(jian)，造成電(dian)(dian)(dian)能的(de)(de)(de)(de)(de)浪費。而(er)在充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)過程的(de)(de)(de)(de)(de)后期，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)又大(da)于蓄(xu)電(dian)(dian)(dian)池(chi)(chi)可接(jie)受(shou)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)流(liu)，蓄(xu)電(dian)(dian)(dian)池(chi)(chi)內部溫度升(sheng)高，產生大(da)量析氣，并形成內部硫化結晶，大(da)大(da)縮短(duan)了(le)蓄(xu)電(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)(de)循環(huan)使(shi)用壽命，甚至有可能永久(jiu)性地(di)損壞電(dian)(dian)(dian)池(chi)(chi)。這(zhe)(zhe)不僅造成了(le)浪費，也增加(jia)了(le)對環(huan)境的(de)(de)(de)(de)(de)污染。同時，這(zhe)(zhe)種(zhong)傳統充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)機采用變壓(ya)器(qi)變壓(ya)整流(liu)，可控硅控制的(de)(de)(de)(de)(de)途徑，技術落后，設備笨重(zhong)，可靠性也差。
    美國科學家馬斯通過(guo)對鉛酸(suan)(suan)蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)(de)大(da)(da)量試驗研究(jiu)，提出了一條(tiao)鉛酸(suan)(suan)蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)可接受的(de)(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)曲線(xian)。在充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)過(guo)程(cheng)的(de)(de)(de)(de)初期，蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)可接受的(de)(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)很大(da)(da)。隨(sui)著充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)過(guo)程(cheng)的(de)(de)(de)(de)延續，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)逐漸按指數規律減小(xiao)。讓充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機的(de)(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)按這樣一條(tiao)理想電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)曲線(xian)變(bian)化(hua)(hua)，就可以(yi)最大(da)(da)限度(du)的(de)(de)(de)(de)提高(gao)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)效(xiao)(xiao)率(lv)。同時，試驗表明，采用脈沖式(shi)的(de)(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)方式(shi)是消除(chu)各種極(ji)(ji)化(hua)(hua)現(xian)(xian)象，提高(gao)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)速度(du)，延長(chang)蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)循(xun)環(huan)使(shi)用壽命(ming)的(de)(de)(de)(de)有(you)效(xiao)(xiao)途(tu)徑。這種充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)方式(shi)是在對蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)過(guo)程(cheng)中適時暫停充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，并適當加入放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)脈沖。當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)停止時，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)(de)歐姆極(ji)(ji)化(hua)(hua)消失(shi)，濃(nong)差極(ji)(ji)化(hua)(hua)和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)化(hua)(hua)學極(ji)(ji)化(hua)(hua)減弱。若能在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)過(guo)程(cheng)中讓其反向放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則極(ji)(ji)化(hua)(hua)現(xian)(xian)象迅速消失(shi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)內部(bu)溫度(du)也會(hui)因放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)而得到(dao)有(you)效(xiao)(xiao)控制。脈沖電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)充(chong)(chong)(chong)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)極(ji)(ji)板有(you)加強其韌性的(de)(de)(de)(de)效(xiao)(xiao)果，可以(yi)大(da)(da)大(da)(da)提高(gao)蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)(de)循(xun)環(huan)使(shi)用壽命(ming)。同時，由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)極(ji)(ji)化(hua)(hua)現(xian)(xian)象的(de)(de)(de)(de)消失(shi)，脈沖電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)又可以(yi)深層次(ci)地激(ji)活電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)內部(bu)的(de)(de)(de)(de)活性物質(zhi)，從(cong)而大(da)(da)幅度(du)提高(gao)蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)有(you)效(xiao)(xiao)容量。
