style="font-size:14px;">（1）</span><span style="font-size:14px;">運(yùn)算電路：將外部的速度、轉(zhuǎn)矩等指令同檢測(cè)電路的電流、電壓信號(hào)進(jìn)行比較運(yùn)算，決定逆變器的輸出電壓、頻率。</span> </p> <p> <span style="font-size:14px;">（2）電壓、電流檢測(cè)電路：與主回路電位隔離檢測(cè)電壓、電流等。</span> </p> <p> <span style="font-size:14px;">（3）驅(qū)動(dòng)電路：驅(qū)動(dòng)主電路器件的電路。它與控制電路隔離使主電路器件導(dǎo)通、關(guān)斷。</span> </p> <p> <span style="font-size:14px;">（4）速度檢測(cè)電路:以裝在異步電動(dòng)機(jī)軸機(jī)上的速度檢測(cè)器(tg、plg等)的信號(hào)為速度信號(hào)，送入運(yùn)算回路，根據(jù)指令和運(yùn)算可使電動(dòng)機(jī)按指令速度運(yùn)轉(zhuǎn)。</span> </p> <p> <span

style="font-size:14px;">變頻器的運(yùn)行和相關(guān)參數(shù)的設(shè)置：</span> </p> <p> <span style="font-size:14px;">變頻器的設(shè)定參數(shù)多，每個(gè)參數(shù)均有一定的選擇范圍，使用中常常遇到因個(gè)別參數(shù)設(shè)置不當(dāng)，導(dǎo)致變頻器不能正常工作的現(xiàn)象。</span> </p> <p> <span style="font-size:14px;">蕞低運(yùn)行頻率：即電機(jī)運(yùn)行的蕞小轉(zhuǎn)速，電機(jī)在低轉(zhuǎn)速下運(yùn)行時(shí)，其散熱性能很差，電機(jī)長(zhǎng)時(shí)間運(yùn)行在低轉(zhuǎn)速下，會(huì)導(dǎo)致電機(jī)燒毀。而且低速時(shí)，其電纜中的電流也會(huì)增大，也會(huì)導(dǎo)致電纜發(fā)熱。</span> </p> <p> <span style="font-size:14px;">控制方式：即速度控制、轉(zhuǎn)距控制、PID控制或其他方式。采取控制方式后，一般要根據(jù)控制精度，需要進(jìn)行靜態(tài)或動(dòng)態(tài)辨識(shí)。</span> </p> <p> <span style="font-size:14px;">載波頻率：載波頻率設(shè)置</span><span style="font-size:14px;">的越高其高次諧波分量越大，這和電纜的長(zhǎng)度，電機(jī)發(fā)熱，電纜發(fā)熱變頻器發(fā)熱等因素是密切相關(guān)的。</span> </p> <p> <br /> </p> <p> <span style="font-size:14px;">蕞高運(yùn)行頻率：一般的變頻器蕞大頻率到60Hz，有的甚至到400Hz，高頻率將使電機(jī)高速運(yùn)轉(zhuǎn)，這對(duì)普通電機(jī)來說，其軸承不能長(zhǎng)時(shí)間的超額定轉(zhuǎn)速運(yùn)行，電機(jī)的轉(zhuǎn)子是否能承受這樣的離心力。</span> </p> <p> <span style="font-size:14px;">跳頻：在某個(gè)頻率點(diǎn)上，有可能會(huì)發(fā)生共振現(xiàn)象，特別在整個(gè)裝置比較高時(shí)；在控制壓縮機(jī)時(shí)，要避免壓縮機(jī)的喘振點(diǎn)。</span> </p> <p> <span

style="font-size:14px;">開環(huán)時(shí)，變頻器即使輸出給定頻率，電機(jī)在帶負(fù)載運(yùn)行時(shí)，電機(jī)的轉(zhuǎn)速在額定轉(zhuǎn)差率的范圍內(nèi)（1%~5%）變動(dòng)。對(duì)于要求調(diào)速精度比較高，即使負(fù)載變動(dòng)也要求在近于給定速度下運(yùn)轉(zhuǎn)的場(chǎng)合，可采用具有PG反饋功能的變頻器（選用件）。具有PG反饋功能的變頻器，精度有提高。但速度精度的值取決于PG本身的精度和變頻器輸出頻率的分辨率。如果給定的加速時(shí)間過短，變頻器的輸出頻率變化遠(yuǎn)遠(yuǎn)超過轉(zhuǎn)速（電角頻率）的變化，變頻器將因流過過電流而跳閘，運(yùn)轉(zhuǎn)停止，這就叫作失速。為了防止失速使電機(jī)繼續(xù)運(yùn)轉(zhuǎn)，就要檢出電流的大小進(jìn)行頻率控制。當(dāng)加速電流過大時(shí)適當(dāng)放慢加速速率。減速時(shí)也是如此。兩者結(jié)合起來就是失速功能。（云南永樂科技變頻器銷售、維修）</span>變頻器維修公司哪家較好？昆明Goodrive20矢量變頻器公司銷售</p><p
