KULICKE & SOFFA 01483-4047-000-05在井下采煤系統(tǒng)應(yīng)用
1、采煤機(jī)ACS-800變頻器的調(diào)試運(yùn)行
ACS-800變頻器有著優(yōu)良的調(diào)速性能和顯著的節(jié)能效果被廣泛應(yīng)用于煤礦及其它眾多行業(yè)。正確設(shè)置變頻器的基本參數(shù)是十分重要的。兗州礦業(yè)(集團(tuán))公司濟(jì)寧二號煤礦總結(jié)了采煤機(jī)ACS-800變頻器調(diào)試運(yùn)行的經(jīng)驗(yàn)。
①選擇語言,設(shè)置電動機(jī)啟動數(shù)據(jù)。有十五種語言可供選擇,應(yīng)選(ENGLISH)英語,(FACTORY)基本應(yīng) 用于工廠、(NO)不恢復(fù)出廠設(shè)置、(DTC)直接轉(zhuǎn)矩控制。根據(jù)電動機(jī)銘牌選擇合適的電壓、頻率范圍、電動機(jī)轉(zhuǎn)速和電動機(jī)功率等。
②KULICKE & SOFFA 01483-4047-000-05通過設(shè)置數(shù)字輸入端,實(shí)現(xiàn)外部啟動、停機(jī)和旋轉(zhuǎn)方向。加速時(shí)間就是變頻器輸出頻率由零頻升到最大頻率所需時(shí)間,一般8~10s。減速時(shí)間是從給定最大值降至零頻所需時(shí)間,一般3~5s。確保加速時(shí)不過流、減速時(shí)不過壓。加、減速時(shí)間可根據(jù)電動機(jī)功率進(jìn)行計(jì)算,實(shí)際應(yīng)用時(shí)根據(jù)現(xiàn)場情況適當(dāng)調(diào)整,以不出現(xiàn)過電流、過電壓為原則。
③加減速模式選擇。變頻器加減速有線形、非線形和S形曲線運(yùn)行模式。采煤機(jī)啟動和運(yùn)行負(fù)載變化較大,且加速度要緩慢,變頻器可選擇S形曲線運(yùn)行模式,以滿足不同的復(fù)雜地質(zhì)條件需要。
④設(shè)置轉(zhuǎn)矩補(bǔ)償。以此來提高電動機(jī)在低速啟動時(shí)轉(zhuǎn)矩提升,應(yīng)采取自動補(bǔ)償功能,確保電動機(jī)加速順利進(jìn)行。
⑤電子過流保護(hù)功能設(shè)置。這是為了保護(hù)電動機(jī)因過流而燒毀,漏電保護(hù)功能對電動機(jī)及電纜實(shí)時(shí)監(jiān)視絕緣情況。工作電流超過設(shè)定值時(shí)過流保護(hù)功能動作,絕緣值下降至設(shè)定值以下時(shí)漏電保護(hù)功能將切斷電源,實(shí)現(xiàn)保護(hù)牽引電動機(jī)的要求。
⑥KULICKE & SOFFA 01483-4047-000-05模擬加載調(diào)試采煤機(jī)。接上電源后仔細(xì)觀察有無異,F(xiàn)象,然后進(jìn)行初加速。在加速時(shí)限制頻率給定時(shí)要緩慢,頻率上升率不要太陡,以防止出現(xiàn)過電流保護(hù)。此時(shí)觀察電動機(jī)轉(zhuǎn)速是否由小到大過渡運(yùn)行平穩(wěn)確保電動機(jī)接近滿載情況下可靠運(yùn)行。
2、電牽引采煤機(jī)變頻器故障分析與處理
電牽引采煤機(jī)應(yīng)用變頻器替代了原先的液壓牽引方式,提高了采煤機(jī)運(yùn)行的可靠性。兗州礦業(yè)(集團(tuán))公司鮑店煤礦通過大量現(xiàn)場實(shí)踐,總結(jié)出使用和維護(hù)變頻器的經(jīng)驗(yàn),保障了電牽引采煤機(jī)的正常運(yùn)行。變頻器位于牽引控制箱的右前側(cè),主要用于控制采煤機(jī)的左右行走速度。
KULICKE & SOFFA 01483-4047-000-05對于采煤機(jī)只能進(jìn)行單向行走的單向牽引事故,除平時(shí)經(jīng)常清理按鈕表面的粉塵,并做好防銹處理以防出現(xiàn)按鈕卡住現(xiàn)象外,還要加強(qiáng)對插座的維護(hù)和保護(hù),控制線在壓接時(shí)用力適度,線頭壓得過緊易出現(xiàn)斷絲,采煤機(jī)振動時(shí)易造成線頭虛接。
對于采煤機(jī)運(yùn)行時(shí)能牽引,但在行走過程中經(jīng)常出現(xiàn)突然停機(jī),停機(jī)后有時(shí)有故障顯示有時(shí)無故障顯示,復(fù)位后仍能開機(jī)的病態(tài)牽引事故,先不要急于動手,首先詢問司機(jī)關(guān)于采煤機(jī)工作運(yùn)行情況和故障現(xiàn)象,觀察功能顯示和參數(shù)顯示,仔細(xì)傾聽采煤機(jī)運(yùn)行聲音,分清是機(jī)械故障還是電氣故障,確定故障范圍,由點(diǎn)到面層層分析,然后再進(jìn)行事故處理。
對于采煤機(jī)不牽引的事故,其原因可分為硬故障和軟故障。硬故障是指采煤機(jī)出現(xiàn)不牽引后信息顯示直觀,能直接從顯示窗口上獲得故障信息。軟故障是指采煤機(jī)出現(xiàn)不牽引后從顯示窗口查不出各種信息,故障點(diǎn)信息較模糊,難以對事故進(jìn)行處理,F(xiàn)場處理是更換功率平衡板。該板是易損件,出現(xiàn)類似事故時(shí)應(yīng)及時(shí)更換。平常應(yīng)加強(qiáng)對變頻器電源輸入聯(lián)接線的維護(hù),采取隔離和包扎等措施,使變頻器電源輸入線不與器壁和其它元件接觸,可有效防止事故發(fā)生。
3、交流電牽引采煤機(jī)綜合試驗(yàn)臺
兗州礦業(yè)(集團(tuán))公司機(jī)械制修廠研制的電牽引采煤機(jī)綜合試驗(yàn)臺,可對MCLE600-DR102102、SL300、MGTY400/900-3.3D三種常用交流電牽引采煤機(jī)的電氣系統(tǒng)進(jìn)行測試,并可同時(shí)對2臺變頻器進(jìn)行試驗(yàn),由2臺變頻器分別拖動2臺交流電動機(jī),也可一拖一或一拖二。
3.1該綜合試驗(yàn)臺由3個(gè)部分組成。
①交流變頻調(diào)速試驗(yàn)單元:主要設(shè)備有油自冷式調(diào)壓器、三相異變電動機(jī)、直流電動機(jī)和數(shù)字式直流調(diào)速裝置、轉(zhuǎn)速轉(zhuǎn)矩傳感器、控制臺,實(shí)現(xiàn)交流變頻調(diào)速裝置電氣性能和牽引電機(jī)及機(jī)械性能的測試,完成變頻調(diào)速裝置保護(hù)功能的測試。能測試的項(xiàng)目主要有變頻器在空載狀態(tài)下的工作性能試驗(yàn)、加載試驗(yàn)、溫升試驗(yàn)、電網(wǎng)電壓波動試驗(yàn)、速度調(diào)節(jié)范圍試驗(yàn)、制動與正反轉(zhuǎn)運(yùn)行試驗(yàn)、機(jī)械調(diào)速特性試驗(yàn)。
②計(jì)算機(jī)信號數(shù)據(jù)處理單元:核心設(shè)備有工業(yè)控制用計(jì)算機(jī)(含模擬量、數(shù)字量、輸入輸出接板)、寬行彩色打印機(jī)、信號調(diào)理變送電路,主要用來采集來自交流變頻調(diào)速單元的信號和數(shù)據(jù),按照測試項(xiàng)目的要求進(jìn)行數(shù)據(jù)處理和顯示。
③KULICKE & SOFFA 01483-4047-000-05采煤機(jī)控制、監(jiān)測系統(tǒng)試驗(yàn)單元:共包括監(jiān)測信號模擬發(fā)生電路(分別模擬采煤機(jī)牽引部、截割部等處的電流、溫度、壓力等檢測信號,能在規(guī)定量程內(nèi)變化,并具備計(jì)量校準(zhǔn)的功能,可以代替原信號送檢測中心)、采煤機(jī)操作信號模擬發(fā)生電路(模擬采煤機(jī)的各種信號,如送電、牽啟、左行、右行等,可以代替原信號控制采煤機(jī)各部的動作)、采煤機(jī)動作響應(yīng)顯示電路(代替采煤機(jī)各部在控制中心輸出信號后作出的響應(yīng)指示),主要對采煤機(jī)控制監(jiān)測系統(tǒng)的功能進(jìn)行測試。
