在風(fēng)機(jī)的電機(jī)與風(fēng)機(jī)之間，配有液力耦合器對風(fēng)機(jī)進(jìn)行調(diào)速，整個工藝過程主要是通過DCS的控制來調(diào)節(jié)液力耦合器的速度從而調(diào)整風(fēng)機(jī)的風(fēng)量，風(fēng)機(jī)依靠風(fēng)門來進(jìn)行調(diào)節(jié)。
由于目前液力耦合器漏油嚴(yán)重，運(yùn)行中每天需加油2～3次，以補(bǔ)充漏油，油面調(diào)整的控制回路失靈不能自動調(diào)節(jié)，在運(yùn)行中靠手動調(diào)節(jié)置于固定轉(zhuǎn)速比。在運(yùn)行時仍靠風(fēng)機(jī)擋板進(jìn)行風(fēng)量調(diào)節(jié)，當(dāng)窯系統(tǒng)工況變化較大時，現(xiàn)場值班人員根據(jù)中控制室的指令對液力耦合器的勺桿進(jìn)行手動調(diào)節(jié)，運(yùn)行操作非常不便。
去年年底，京蘭三源水泥有限公司決定對生產(chǎn)線的循環(huán)風(fēng)機(jī)進(jìn)行高壓變頻節(jié)能改造，通過考察，深圳微能科技有限公司以其優(yōu)秀的技術(shù)方案、良好的運(yùn)行業(yè)績、規(guī)�；纳a(chǎn)能力以及專業(yè)的售后服務(wù)等，得到了公司技術(shù)人員的一致認(rèn)可。深圳微能科技有限公司經(jīng)過多方的研究和論證，將循環(huán)風(fēng)機(jī)由原來的閥門調(diào)節(jié)改為變頻調(diào)速調(diào)節(jié)，考慮到系統(tǒng)工作可能停機(jī)的極限情況，配置了一拖一手動旁路柜。運(yùn)行實(shí)踐證明，達(dá)到了預(yù)期的節(jié)能效果。

改造方案設(shè)計
該設(shè)備有二種控制方式：
1、以轉(zhuǎn)速為控制對象的開環(huán)控制：該方式在遠(yuǎn)程操作（DCS或遠(yuǎn)程操作箱上操作）用戶可根據(jù)工況條件自設(shè)定轉(zhuǎn)速，變頻器以該轉(zhuǎn)速為控制值，該方式下頻率的變化依據(jù)用戶輸入的模擬量，4mA對應(yīng)0轉(zhuǎn)速，20mA對應(yīng)額定轉(zhuǎn)速。
2、以頻率為控制對象的開環(huán)控制：該方式在就地操作（設(shè)備本體上操作）直接從觸摸屏上設(shè)置輸出頻率，變頻器以該頻率為控制目標(biāo)值。
以上二種控制方式用戶可通過人機(jī)界面（觸摸屏）設(shè)置，滿足不同的工況要求。

微能高壓變頻器介紹
1、 微能高壓大功率變頻器由多個功率單元構(gòu)成多重化串聯(lián)的拓?fù)浣Y(jié)構(gòu)，每個單元輸出固定的低壓電平，再由多個單元串聯(lián)疊加為所需的高壓，見圖所示
以10kV每相九個單元串聯(lián)為例,每相由九個相同的功率單元串聯(lián)而成，相電壓為5773V。每個功率單元輸出有效值Ve＝641V。多重化串聯(lián)結(jié)構(gòu)使用低壓器件實(shí)現(xiàn)了高壓輸出，不僅降低了對功率器件的耐壓要求，而且還使輸出波形得到了極大的改善。它對電網(wǎng)諧波污染非常小，輸入電流諧波畸變率小于4%，滿足IEEE519-1992的諧波抑制標(biāo)準(zhǔn)；輸入功率因數(shù)高，不必采用輸入諧波濾波器和功率因數(shù)補(bǔ)償裝置；輸出波形接近正弦波，不存在輸出諧波引起的電機(jī)發(fā)熱和轉(zhuǎn)矩脈動、噪音、輸出dv/dt、共模電壓等問題，對普通異步電機(jī)不必加輸出濾波器就可以直接使用。
