style="font-size:14px;">現(xiàn)在的電梯都是用變頻器來控制的,如果變頻器出現(xiàn)故障就會給很多人帶來不便，管理人員也會很著急，如果平時(shí)對變頻器有進(jìn)行保養(yǎng)，這樣就降低了變頻器的故障率，下面就來講講電梯變頻器平時(shí)保養(yǎng)的注意事項(xiàng)：</span> </p> <p> <span style="font-size:14px;">1、變頻器的散熱風(fēng)扇要定時(shí)清塵，發(fā)現(xiàn)其有響聲或不運(yùn)轉(zhuǎn)就要更換。</span> </p> <p> <span style="font-size:14px;">2、防止雨水淋濕，通常是在刮臺風(fēng)時(shí)，窗門被風(fēng)吹壞而使變頻器淋到雨水。</span> </p> <p> <span style="font-size:14px;">3、防雷電，這個(gè)就關(guān)系到整棟樓或整個(gè)小區(qū)防雷設(shè)施問題，被雷擊的變頻器一般損壞嚴(yán)重。</span> </p> <p> <span style="font-size:14px;">4、電梯電氣室溫度不能太高，否則變頻器元件容易老化，蕞好裝有空調(diào)，效果會更好。</span> </p> <p> <span style="font-size:14px;">5、電梯電機(jī)有不正常響聲通常是變頻器有問題，如電機(jī)三相電流不平衡，這時(shí)蕞好就要維修，等到變頻器完全不行則損壞可能比較嚴(yán)重。如果自己沒有維修經(jīng)驗(yàn)，一定要請專業(yè)維修人員修理。</span> </p><p style="text-indent:25px"><span style="font-size:14px;">步入21世紀(jì)后，國產(chǎn)變頻器逐步崛起，現(xiàn)已逐漸搶占市場。上海和深圳成為國產(chǎn)變頻器發(fā)展的前沿陣地，涌現(xiàn)出了像匯川變頻器、英威騰變頻器、安邦信變頻器、歐瑞變頻器等一批**國產(chǎn)變頻器。其中安邦信變頻器成立于1998年，是我國蕞早生產(chǎn)變頻器的廠家之一。十幾年來，安邦信人以渾厚的文化底蘊(yùn)作基石，支撐著成長，企業(yè)較早通過TUV機(jī)構(gòu)ISO9000質(zhì)量體系認(rèn)證，被授予“******”，多年被評為“中國變頻器用戶滿意**國內(nèi)品牌”。（云南永樂科技變頻器銷售、維修）</span>共同成長，共同發(fā)展。</p><div

style="font-size:14px;">類方法有很多種。根據(jù)主電路的工作方式，可分為電壓型逆變器和電流型逆變器；按開關(guān)方式可分為PAM控制型逆變器、PWM控制型逆變器和高載頻PWM控制型逆變器；按工作原理可分為v/F控制型逆變器，轉(zhuǎn)差變頻調(diào)速逆變器和矢量控制逆變器按應(yīng)用分類，可分為通用變頻器、高性能**變頻器、高頻變頻器、單相變頻器和三相變頻器。</span> </p> <p> <span style="font-size:14px;">VVVF：變壓、變頻CVCF：恒壓、恒頻。各國使用的交流電源的電壓和頻率是400V/50Hz或200V/60Hz（50Hz）等，通常把固定電壓和頻率的交流電轉(zhuǎn)換成可變電壓或頻率的交流電的裝置稱為“變頻器”。為了產(chǎn)生可變電壓和頻率，該裝置首先將電源的交流電轉(zhuǎn)換為直流電（DC）。</span>
