style="font-size:14px;">現(xiàn)在的電梯都是用變頻器來(lái)控制的,如果變頻器出現(xiàn)故障就會(huì)給很多人帶來(lái)不便，管理人員也會(huì)很著急，如果平時(shí)對(duì)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(lái)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(tái)風(fēng)時(shí)，窗門(mén)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(wèn)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(huì)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(wèn)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(méi)有維修經(jīng)驗(yàn)，一定要請(qǐng)專業(yè)維修人員修理。</span> </p><p> <span style="font-size:14px;">在變頻器維修時(shí)應(yīng)注意的維修事項(xiàng)是什么呢？</span> </p> <p> <span style="font-size:14px;">1、變頻器不要裝在有震動(dòng)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(dòng)，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(wèn)題問(wèn)題：變頻器輸入端蕞好接上一個(gè)空氣開(kāi)關(guān)包庇電流的值不能太大，以防止暴發(fā)短路時(shí)燒毀不會(huì)太嚴(yán)重。必定不能將“N”端接地。節(jié)制線盡可能不要太長(zhǎng)。由于這樣使節(jié)制板輕易受電磁波煩擾而產(chǎn)生誤動(dòng)作，也會(huì)導(dǎo)致節(jié)制板破損，超出2米長(zhǎng)的zui好用樊籬線。變頻器旁邊不要裝有大電流而且常常動(dòng)作的接觸器，由于它對(duì)變頻器煩擾非常大，常常使</span><span style="font-size:14px;">變頻器誤動(dòng)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(chē)的變頻器zui好不要依托變頻器本人剎車(chē)，而是另加剎車(chē)電陰或采用機(jī)械剎車(chē)，否則變頻器常常受電機(jī)反電動(dòng)勢(shì)沖擊，毛病舛誤率會(huì)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(shí)打掃電路板及散熱器上的塵埃；停機(jī)一段時(shí)刻的變頻器在通電前zui好用電吹風(fēng)吹一下電路板。</span> 云南變頻器哪家較好？</p><div style="width:100%;text-align:
