id="hits">0</span></div> <div id="w4ykmuk" class="acontent"> <strong>變頻器諧波</strong>是指由于正弦電壓加壓于非線(xiàn)性負(fù)載變頻器，基波電流發(fā)生畸變而產(chǎn)生的諧波。對(duì)于一臺(tái)變頻器來(lái)講，它的輸入端和輸出端都會(huì)產(chǎn)生高次諧波，輸入端的諧波還會(huì)通過(guò)輸入電源線(xiàn)對(duì)公用電網(wǎng)產(chǎn)生影響。變頻器本身輸入側(cè)是一個(gè)非線(xiàn)性整流電路，對(duì)電源的波形將有影響，變頻器輸出側(cè)電壓、電流、非正弦或非完全正弦波含有豐富的諧波。<br /> 一般來(lái)講，變頻器對(duì)容量大的電力系統(tǒng)影響不是十分明顯，但是對(duì)于系統(tǒng)容量小的系統(tǒng)，諧波產(chǎn)生的干擾就不可忽視，它對(duì)公用電網(wǎng)是一種污染，客觀(guān)的存在對(duì)公用電網(wǎng)和其它系統(tǒng)的危害大致有：<br /> （1）變頻器諧波使公用電網(wǎng)的元件產(chǎn)生了附加的諧波損耗，降低了發(fā)電、輸電及用電設(shè)備的使用率，大量的三次諧波流過(guò)中線(xiàn)時(shí)會(huì)使線(xiàn)路過(guò)熱甚至發(fā)生火災(zāi)。<br /> （2）變頻器諧波影響各種電氣元件的正常工作。諧波對(duì)電機(jī)的影響除引起附加損耗外，還會(huì)產(chǎn)生機(jī)械振動(dòng)、噪音和過(guò)電流，使電容器、電纜等設(shè)備過(guò)熱，絕緣老化、壽命縮短以至損壞。<br /> （3）變頻器諧波會(huì)引起公用電網(wǎng)局部的并聯(lián)諧振和串聯(lián)諧振，從而使諧波放大，這就使上述的危害大大的增加，甚至引起嚴(yán)重事故。<br /> （4）變頻器諧波會(huì)對(duì)臨近的通訊系統(tǒng)產(chǎn)生干擾，導(dǎo)致通訊質(zhì)量降低，甚至信息的丟失，使通訊系統(tǒng)無(wú)法正常工作。<br /> 治理變頻器諧波問(wèn)題，抑制輻射干擾和供電系統(tǒng)干擾，可采取屏蔽、隔離、接地等技術(shù)手段。<br /> <br /> 1、安裝適當(dāng)?shù)碾娍蛊?br /> 在變頻器輸入側(cè)與輸出側(cè)串接合適的電抗器，吸收諧波和增大電源或負(fù)載的阻抗，達(dá)到抑制諧波的目的，以減少傳輸過(guò)程中的電磁輻射。通過(guò)抑制諧波電流，將功率因數(shù)由原來(lái)的(0.5-0.6)提高至（0.75-0.85）；<br /> 2、電源隔離或安裝隔離變壓器<br /> 將變頻系統(tǒng)的供電電源與其他設(shè)備的供電電源相互獨(dú)立，或在變頻器和其他用電設(shè)備的輸入側(cè)安裝隔離變壓器，切斷諧波電流；<br /> 3、避免干擾輻射<br /> 電動(dòng)機(jī)和變頻器之間電纜應(yīng)穿鋼管敷設(shè)或用鎧裝電纜，并與其他弱電信號(hào)在不同的電纜溝分別敷設(shè)，避免輻射干擾；<br /> 4、變頻器正確的接地<br /> 正確的接地既可以使系統(tǒng)有效地抑制外來(lái)干擾，又能降低設(shè)備本身對(duì)外界的干擾。變頻器使用專(zhuān)用接地線(xiàn)，且用粗短線(xiàn)接地，鄰近其他電器設(shè)備的地線(xiàn)必須與變頻器配線(xiàn)分開(kāi)，使用短線(xiàn)，這樣能有效抑制電流諧波對(duì)鄰近設(shè)備的輻射干擾；<br /> 5、縮短線(xiàn)路長(zhǎng)度<br /> 縮短線(xiàn)路長(zhǎng)度，電源線(xiàn)和信號(hào)線(xiàn)單獨(dú)敷設(shè)，避免交叉，不能避免時(shí)，必須垂直交叉，絕對(duì)不能平等敷設(shè)，信號(hào)線(xiàn)屏蔽層不接到電機(jī)或變頻器的地，而應(yīng)該接到控制線(xiàn)路的公共端；<br /> 6、安裝EMI電源濾波器<br /> 當(dāng)前抑制變頻器諧波的一個(gè)重要趨勢(shì)是采用EMI電源濾波器，它串聯(lián)或是并聯(lián)于主電路中，實(shí)時(shí)從補(bǔ)償對(duì)象中檢測(cè)出變頻器諧波電流，由補(bǔ)償裝置產(chǎn)生一個(gè)與該變頻器諧波電流大小相等、方向相反的補(bǔ)償電流，從而使電網(wǎng)電流只含基波電流。EMI電源濾波器能對(duì)頻率和幅值都變化的變頻器諧波進(jìn)行跟蹤補(bǔ)償，其特性不受系統(tǒng)的影響，無(wú)諧波放大的危險(xiǎn)，因而獲得了廣泛的應(yīng)用。</div>
