主井皮帶原采用2臺高壓電機拖動，整套系統(tǒng)工作是由2臺315kW/6kV高壓異步電動機并聯(lián)拖動。
主井皮帶是柳灣煤礦的中樞，一旦皮帶機不能正常工作，將造成全礦停產(chǎn)，不但影響生產(chǎn)，造成巨大經(jīng)濟損失，而且會引起嚴重的社會影響。
原有系統(tǒng)采用交流繞線式電機串電阻調(diào)速系統(tǒng)。該調(diào)速系統(tǒng)屬于有級調(diào)速，調(diào)速的平滑性差；低速時機械特性較軟，靜差率較大；電阻上消耗的轉(zhuǎn)差功率大，節(jié)能較差；起動過程和調(diào)速換擋過程中電流沖擊大；中高速運行震動大，安全性較差。該調(diào)速系統(tǒng)在解決電機間同步，以及出力不均的問題時能力明顯不足。機械磨損和老化問題日趨嚴重，性能逐年降低，故障率增加，設(shè)備維修難度大;整個系統(tǒng)效率低，調(diào)速范圍有限，穩(wěn)定性差。
3. 變頻調(diào)速新系統(tǒng)裝置概述
主井皮帶采用3臺高壓電機拖動，整套系統(tǒng)工作是由3臺710kW/6kV高壓異步電動機并聯(lián)拖動。其中兩臺電機同軸拖動同一滾筒，另一電機單獨驅(qū)動另一滾筒，皮帶運輸機傳動系統(tǒng)如圖1所示。
該系統(tǒng)不僅要求3臺速度同步，而且3臺負荷分配要均衡一致，如圖2所示。
綜合以上因素，甲方考慮采用高壓變頻調(diào)速裝置驅(qū)動皮帶系統(tǒng)，但是，由于目前國內(nèi)外高壓變頻器的應用領(lǐng)域主要在風機水泵等變轉(zhuǎn)矩應用方面，很少有恒轉(zhuǎn)矩重載設(shè)備驅(qū)動的實例，而重載多單元同步控制的成功應用更是幾乎沒有，新柳煤礦非常慎重，經(jīng)過綜合考查了國內(nèi)外多家變頻廠商，同各方面專家進行了多次的研討，最終確認了日本明電舍的VT710高壓變頻器驅(qū)動裝置的系統(tǒng)方案。圖２為皮帶運輸機高壓變頻器驅(qū)動系統(tǒng)圖。
