混合型制(zhi)動(dong)能量(liang)吸(xi)收(shou)裝置

混合型(xing)(xing),即能饋型(xing)(xing)和能耗型(xing)(xing)的(de)組(zu)合型(xing)(xing)式,或(huo)其(qi)他(ta)兩種模(mo)式組(zu)合。既具(ju)有(you)能耗型(xing)(xing)的(de)穩定、投(tou)資小的(de)特點,又具(ju)備能饋型(xing)(xing)經(jing)濟(ji)適用的(de)優勢。

城市(shi)軌(gui)道交(jiao)通(tong)(tong)工程(cheng)中(zhong)(zhong),普遍采用(yong)(yong)直(zhi)交(jiao)變壓(ya)變頻(pin)的(de)(de)傳動(dong)(dong)(dong)(dong)方式,車(che)輛的(de)(de)制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)方式為電(dian)(dian)(dian)制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(再(zai)(zai)生(sheng)制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong))+機械制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong),運(yun)(yun)行(xing)中(zhong)(zhong)以(yi)電(dian)(dian)(dian)制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)為主,機械制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)為輔。列(lie)(lie)車(che)在運(yun)(yun)行(xing)過(guo)程(cheng)中(zhong)(zhong),由于站(zhan)間(jian)距(ju)較短,列(lie)(lie)車(che)啟動(dong)(dong)(dong)(dong)、制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)頻(pin)繁(fan),制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)能(neng)量(liang)(liang)相(xiang)當可觀。根據經驗,地鐵再(zai)(zai)生(sheng)制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)產(chan)生(sheng)的(de)(de)能(neng)量(liang)(liang)除了(le)一(yi)定比例(一(yi)般為20%~80%,根據列(lie)(lie)車(che)運(yun)(yun)行(xing)密度和(he)區(qu)間(jian)距(ju)離的(de)(de)不同(tong)而異)被(bei)其(qi)他相(xiang)鄰(lin)列(lie)(lie)車(che)吸收(shou)(shou)(shou)利用(yong)(yong)外,剩余部(bu)分將(jiang)(jiang)主要(yao)被(bei)列(lie)(lie)車(che)的(de)(de)吸收(shou)(shou)(shou)電(dian)(dian)(dian)阻(zu)以(yi)發熱(re)的(de)(de)方式消耗掉或被(bei)線路(lu)上的(de)(de)吸收(shou)(shou)(shou)裝置(zhi)吸收(shou)(shou)(shou)。目前國內城市(shi)軌(gui)道交(jiao)通(tong)(tong)主要(yao)吸收(shou)(shou)(shou)方式是(shi)采用(yong)(yong)電(dian)(dian)(dian)阻(zu)能(neng)耗吸收(shou)(shou)(shou)裝置(zhi)處理列(lie)(lie)車(che)運(yun)(yun)行(xing)過(guo)程(cheng)中(zhong)(zhong)的(de)(de)再(zai)(zai)生(sheng)能(neng)量(liang)(liang),這(zhe)不僅(jin)浪費(fei)(fei)能(neng)量(liang)(liang),而且也增(zeng)加(jia)了(le)站(zhan)內空(kong)調通(tong)(tong)風裝置(zhi)的(de)(de)負擔,并使城軌(gui)建設費(fei)(fei)用(yong)(yong)和(he)運(yun)(yun)行(xing)費(fei)(fei)用(yong)(yong)增(zeng)加(jia)。如(ru)能(neng)將(jiang)(jiang)這(zhe)部(bu)分能(neng)量(liang)(liang)吸收(shou)(shou)(shou)再(zai)(zai)利用(yong)(yong),這(zhe)些問題將(jiang)(jiang)迎刃而解。

混合(he)(he)型(xing)(xing),即能(neng)饋(kui)型(xing)(xing)和(he)能(neng)耗(hao)型(xing)(xing)的組(zu)合(he)(he)型(xing)(xing)式,或其他兩種模(mo)式組(zu)合(he)(he)。既具有能(neng)耗(hao)型(xing)(xing)的穩定、投(tou)資小(xiao)的特點,又具備能(neng)饋(kui)型(xing)(xing)經濟(ji)適用(yong)的優勢。
