結(jié)構(gòu)上也比較簡(jiǎn)單。但是簡(jiǎn)單電路也可能會(huì)產(chǎn)生疑難故障。開關(guān)電源的檢修不像線性電源那么直觀,電路的任一個(gè)小環(huán)節(jié)一振蕩、穩(wěn)壓、保護(hù)、負(fù)載等出現(xiàn)異常,都會(huì)使電路出現(xiàn)各種各樣的故障現(xiàn)象。上電后無反應(yīng),操作顯示面板無顯示,變頻器好像沒通電一樣。測(cè)量控制端子的控制電壓和10V頻率調(diào)整電壓都為0,測(cè)量變頻器主接線端子電阻正常,那么大致上可以斷定問題是出在開關(guān)電源電路了。過熱保護(hù)編輯主要有以下幾點(diǎn):⑴風(fēng)扇運(yùn)轉(zhuǎn)保護(hù)變頻器的內(nèi)裝風(fēng)扇是箱體內(nèi)部散熱的主要手段,它將保證控制電路的正常工作。所以,如果風(fēng)扇運(yùn)轉(zhuǎn)不正常,應(yīng)立即進(jìn)行保護(hù);⑵逆變模塊散熱板的過熱保護(hù)逆變模塊是變頻器內(nèi)發(fā)生熱量的主要部件,也是變頻器中重要而又脆弱的部件。
