style="font-size:14px;">本公司業(yè)務(wù)內(nèi)容涵蓋自動化控制系統(tǒng)及系統(tǒng)集成的開發(fā)設(shè)計、生產(chǎn)制造、安裝調(diào)試、技術(shù)服務(wù)、商業(yè)貿(mào)易等，行業(yè)涉及能源、化工、水泥、醫(yī)藥、食品、造紙、裝配、制造、環(huán)保等，工程貿(mào)易遍及云貴川，部分產(chǎn)品遠銷至緬甸、泰國、越南、老撾等東南亞國家。</span> </p> <p> <span style="font-size:14px;">主營產(chǎn)品：變頻器、軟起動器、可編程控制器（PLC）、伺服控制器、人機界面、傳感器、開關(guān)電源、工業(yè)風機、制動單元及低壓電氣產(chǎn)品等。主要工程：變頻柜成套、電氣柜成套、恒壓</span><span style="font-size:14px;">供水系統(tǒng)、DCS系統(tǒng)工程、電氣控制及過程控制系統(tǒng)工程等。設(shè)備維修：變頻器維修、軟起動器維修、可編程控制器（PLC）維修、人機界面維修等。</span> </p><p> <span style="font-size:14px;">按直流電源性質(zhì)分類：</span> </p> <p> <span style="font-size:14px;">a.電流型變頻器.電流型變頻器特點是中間直流環(huán)節(jié)采用大電感作為儲能環(huán)節(jié)，緩沖無功功率，即扼制電流的變化，使電壓接近正弦波，由于該直流內(nèi)阻較大，故稱電流源型變頻器（電流型）。電流型變頻器的特點（優(yōu)點）是能扼制負載電流頻繁而急劇的變化。常選用于負載電流變化較大的場合；</span> </p> <p> <span style="font-size:14px;">b.電壓型變頻器.電壓型變頻器特點是中間直流環(huán)節(jié)的儲能元件采用大電容，負載的無功功率將由它來緩沖，直流電壓比較平穩(wěn)，直流電源內(nèi)阻較小，相當于電壓源，故</span><span style="font-size:14px;">稱電壓型變頻器，常選用于負載電壓變化較大的場合。</span> 公司恪守“共創(chuàng)、共享、共贏”的企業(yè)精神，奉行“知人善任、人盡其才”的人才理念。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="云南英威騰變頻器廠家,變頻器"

style="font-size:14px;">變頻器是利用電力半導體器件的通斷作用將工頻電源變換為另一頻率的電能控制裝置，能實現(xiàn)對交流異步電機的軟起動、變頻調(diào)速、提高運轉(zhuǎn)精度、改變功率因數(shù)、過流/過壓/過載保護等功能。</span> </p> <p> <span style="font-size:14px;">2、PWM和PAM的不同點是什么？</span> </p> <p> <span style="font-size:14px;">PWM是英文PulseWidthModulation(脈沖寬度調(diào)制)縮寫，按一定規(guī)律改變脈沖列的脈沖寬度，以調(diào)節(jié)輸出量和波形的一種調(diào)制方式。PAM是英文PulseAmplitudeModulation(脈沖幅值調(diào)制)縮寫，是按一定規(guī)律改變脈沖列的脈沖幅度，以調(diào)節(jié)輸出量值和波形的一種調(diào)制方式。</span>

style="font-size:14px;">在變頻器實際應(yīng)用中，由于國內(nèi)客戶除少數(shù)有**機房外，大多為了降低成本，將變頻器直接安裝于工業(yè)現(xiàn)場。工作現(xiàn)場一般有灰塵大、溫度高、濕度大的問題，還有如鋁行業(yè)中有金屬粉塵、腐蝕性氣體等等。因此必須根據(jù)現(xiàn)場情況做出相應(yīng)的對策：</span> </p> <p> <span style="font-size:14px;">1、變頻器應(yīng)該安裝在控制柜內(nèi)部。</span> </p> <p> <span style="font-size:14px;">2、變頻器較好安裝在控制柜內(nèi)的中部；變頻器要垂直安裝，正上方和正下方要避免安裝可能阻擋排風、進風的大元件。</span> </p> <p> <span style="font-size:14px;">3、變頻器上、下部邊緣距離控制柜頂部、底部、或者隔板、或者必須安裝的大元件等的蕞小間距，應(yīng)該大于300 mm。</span> </p> <p> <span style="font-size:14px;">4、如果特殊用戶在使用中需要取掉鍵盤，則變頻器面板的鍵盤孔，一定要用膠帶嚴格密封或者采用假面板替換，防止粉塵大量進入變頻器內(nèi)部。</span> </p> <p> <span style="font-size:14px;"><strong>（云南永樂科技變頻器銷售、維修</strong></span><strong>）</strong>
