【正文】 鉆機振動大，對調(diào)速設備的防振要求高。牙輪鉆機上應用變頻調(diào)速技術(shù)不僅是為了節(jié)能，更重要的是為了提高鉆機的生產(chǎn)效率，降低維修工作量。目前，牙輪鉆機的回轉(zhuǎn)機構(gòu)和提升、行走機構(gòu)一般都是直流電動機傳動。第四臺逆變器供電給容量為294kW推壓電動機。變頻調(diào)速由德國SIEMENS公司開發(fā)、提供的電壓型變頻器。H2300XP和Pamp。要求系統(tǒng)運行可靠，維修方便等。 挖掘機用于裝載礦巖，其工作條件非常惡劣，特別是在爆破不好的情況下挖根底作業(yè)，經(jīng)常出現(xiàn)過大的沖擊載荷，甚至堵轉(zhuǎn)。因此，井下生產(chǎn)設備的體積受限，這些設備以小型化為主，體積小、重量輕，對電氣傳動的要求不高。露天礦山的這些大型設備包括用于穿孔的牙輪鉆機，用于裝載礦、巖石的挖掘機，用于運輸?shù)V、巖石的大型汽車等。本文主要對變頻器在煤礦中的應用作以介紹。加強節(jié)能降耗工作是落實科學發(fā)展觀、實施可持續(xù)發(fā)展戰(zhàn)略、轉(zhuǎn)變經(jīng)濟發(fā)展方式的必然途徑。據(jù)統(tǒng)計，104t標準煤,108kW關(guān)鍵詞：煤礦 變頻器 能源 調(diào)速 應用 變頻調(diào)速 節(jié)能Change the Pin adjust soon a machine in the application in the mineral mountainSummary: The energy is the foundation of national economy and society development and strategy resources, the energy problem have already bee economy society can keep on develop of a rigid control economy energy to decline to consume work is implementation science development view, implement can keep on development strategy, change economy development way of inevitable to statistics, our country the coal mine mine just in 2005 namely consume ability the 104 t standard coal, consume electricity s 108 kW?H, respectively have a whole country total consume energy with total consume electricity quantity % and %, so, coal industry be rated as our country one energy industry, since is the productivity big door, again is consume ability big door, also in the meantime is economy energy the potential big door. So, in the coal mine application change the Pin adjust soon a technique coal mine for the exaltation produce equipments of efficiency, economy energy all go to pass importance text is main to make with the introduction towards change Pin machine in the coal mine of apply.Keyword: Coal mine Change Pin machine Energy Adjust soon Application Change the Pin adjust soonEconomy energy 第一章 緒論 礦山的分類礦山按產(chǎn)品類型可分為煤礦、金屬礦和非金屬等。它們都要求電氣傳動系統(tǒng)具有良好的調(diào)速性能，目前這些大型設備大多采用直流調(diào)速傳動系統(tǒng)。但提升、排水、通風、壓氣等固定設備是地下礦山的要害部門，也是耗電大戶，因此，這些設備的安全運行和節(jié)能就顯得至關(guān)重要。因此，挖掘機對電氣傳動系統(tǒng)就有較高的要求:要求電氣傳動系統(tǒng)的機械特性曲線的包絡面積大，有足夠的有用功率。由于挖掘機對電氣傳動系統(tǒng)的這些特殊要求，所以，我國挖掘機目前
