河(he)南中鴻煤(mei)化(hua)公(gong)司鐵路運輸系統(tong)工(gong)程位于河(he)南省平頂山市石龍(long)區，鐵路專用(yong)線(xian)離廠區約3公(gong)里，采用(yong)一條(tiao)管(guan)徑(jing)f= 350mm，帶速 V=3.15m/s，輸送(song)出力煤：Q煤=500t/h，焦碳：Q焦碳=300t/h的(de)雙向(xiang)運行的(de)管(guan)(guan)(guan)狀帶(dai)(dai)式輸送(song)(song)機(ji)輸送(song)(song)，管(guan)(guan)(guan)帶(dai)(dai)機(ji)系統工(gong)作時，可(ke)同(tong)時或分別輸送(song)(song)煤(mei)(mei)(mei)及(ji)焦(jiao)(jiao)炭，煤(mei)(mei)(mei)從鐵路專用線輸煤(mei)(mei)(mei)皮(pi)(pi)帶(dai)(dai)經管(guan)(guan)(guan)帶(dai)(dai)機(ji)上管(guan)(guan)(guan)帶(dai)(dai)輸送(song)(song)至焦(jiao)(jiao)化廠(chang)輸煤(mei)(mei)(mei)皮(pi)(pi)帶(dai)(dai)，焦(jiao)(jiao)炭從焦(jiao)(jiao)化廠(chang)輸焦(jiao)(jiao)皮(pi)(pi)帶(dai)(dai)經管(guan)(guan)(guan)帶(dai)(dai)機(ji)下管(guan)(guan)(guan)帶(dai)(dai)輸送(song)(song)至鐵路專用線輸焦(jiao)(jiao)皮(pi)(pi)帶(dai)(dai)。
輸(shu)送機采用ABB變頻器驅動(dong)，電(dian)壓(ya)等級為0.6KV。頭部(bu)采用兩(liang)臺480KW的ABB變頻器通過光纖通信進行主從控(kong)制，實現同步驅動，并通過 DP通信同(tong)PLC進行(xing)通(tong)信。尾部采用一臺480KW的ABB變頻器通過 DP通信(xin)同PLC進(jin)行通信(xin)，頭(tou)尾電機都采(cai)用柔性連接進(jin)行速度控制(zhi)模式，尾部(bu)還實行力矩限幅從而實現三臺電機的同步驅動。
; 輸送機電(dian)氣(qi)控制(zhi)系(xi)統在機頭設10KV開關(guan)柜(ju)、電力雙(shuang)線圈變壓(ya)器(qi)(10/0.69kV、10/0.4kV)及0.4KV低壓配電屏(ping)，分別在(zai)機頭配電室提供0.4KV電源。在機(ji)尾(wei)設6KV開關柜、電(dian)力變壓器(6/0.69kV、6/0.4kV)及(ji)0.4KV低壓配電屏(ping)，分別在機尾配電室提供0.4KV電源。整條輸送帶從(cong)頭部和尾部2個電(dian)(dian)(dian)源(yuan)點向輸送機沿線檢(jian)修(xiu)電(dian)(dian)(dian)源(yuan)、照明電(dian)(dian)(dian)源(yuan)和攝像(xiang)頭電(dian)(dian)(dian)源(yuan)供電(dian)(dian)(dian)，每個電(dian)(dian)(dian)源(yuan)點供電(dian)(dian)(dian)半(ban)徑為(wei)1500m，用低壓電纜向遠處供電。 |
