style="font-size:14px;">1、變頻器不要裝在有震動的設(shè)備上，由于這樣變頻器里面的主回路聯(lián)接螺絲輕易松動，有很多變頻器就由于這啟事而破損。</span> </p> <p> <span style="font-size:14px;">2、接線問題問題：變頻器輸入端蕞好接上一個空氣開關(guān)包庇電流的值不能太大，以防止暴發(fā)短路時燒毀不會太嚴(yán)重。必定不能將“N”端接地。節(jié)制線盡可能不要太長。由于這樣使節(jié)制板輕易受電磁波煩擾而產(chǎn)生誤動作，也會導(dǎo)致節(jié)制板破損，超出2米長的zui好用樊籬線。變頻器旁邊不要裝有大電流而且常常動作的接觸器，由于它對變頻器煩擾非常大，常常使</span><span style="font-size:14px;">變頻器誤動作（閃現(xiàn)各類毛病舛誤）。</span> </p> <p> <span style="font-size:14px;">3、常常要急停車的變頻器zui好不要依托變頻器本人剎車，而是另加剎車電陰或采用機(jī)械剎車，否則變頻器常常受電機(jī)反電動勢沖擊，毛病舛誤率會大猛前進(jìn)。</span> </p> <p> <span style="font-size:14px;">4、假定變頻器常常低速運(yùn)轉(zhuǎn)15HZ以下，則電機(jī)要另加散熱風(fēng)扇！</span> </p> <p> <span style="font-size:14px;">5、塵埃與潮濕是變頻器的致命。蕞好能將變頻器拆卸在空調(diào)房里，或裝在有慮塵網(wǎng)的電柜里，要按時打掃電路板及散熱器上的塵埃；停機(jī)一段時刻的變頻器在通電前zui好用電吹風(fēng)吹一下電路板。</span> </p><p style="text-indent:25px"><span style="font-size:14px;">變頻器還可以廣泛應(yīng)用于傳送、起重、擠壓和機(jī)床等各種機(jī)械設(shè)備控制領(lǐng)域，它可以提高工藝水平和產(chǎn)品質(zhì)量，減少設(shè)備的沖擊和噪聲，延長設(shè)備的使用壽命。采用變頻調(diào)速控制后，使機(jī)械系統(tǒng)簡化，操作和控制更加方便，有的甚至可以改變原有的工藝規(guī)范，從而提高了整個設(shè)備的功能。例如，紡織和許多行業(yè)用的定型機(jī)，機(jī)內(nèi)溫度是靠改變送入熱風(fēng)的多少來調(diào)節(jié)的。輸送熱風(fēng)通常用的是循環(huán)風(fēng)機(jī)，由于風(fēng)機(jī)速度不變，送入熱風(fēng)的多少只有用風(fēng)門來調(diào)節(jié)。如果風(fēng)門調(diào)節(jié)失靈或調(diào)節(jié)不當(dāng)就會造成定型機(jī)失控，從而影響成品質(zhì)量。（昆明變頻器銷售維修公司）</span>科技創(chuàng)新、質(zhì)量**。</p><div
