變頻器的維護及保養(yǎng)就顯得尤為重要，那怎么樣才可以降低故障率，讓變頻器的度過夏天，減少客戶損失呢?因此，現(xiàn)在主要從以下幾方面簡單介紹：

一、夏季變頻器維修保養(yǎng)注意這幾點，適宜的溫度，濕度，通風，無塵無干擾，對變頻器進行內部、外部的清掃。

二、直接影響變頻器散熱的主要方面?

1、風扇運轉保護，變頻器的內裝風扇是箱體內部散熱的主要手段，它將保證控制電路的正常工作。所以，如果風扇運轉不正常，應立即進行維護。

2、逆變模塊散熱板的過熱保護逆變模塊是變頻器內發(fā)生熱量的主要部件，也是變頻器中*重要而又*脆弱的部件。所以，各變頻器都在散熱板上配置了過熱保護器件。

3、冷卻風道的入口和出口不得堵塞，環(huán)境溫度也可能高于變頻器的允許值。有針對性地提出了一些解決問題的方法及改進的建議，對于變頻器在實際工程中的應用有的參考價值。

4、干擾問題要注意變頻器對微機控制板的干擾問題。用戶自己設計的微機控制板工藝水平差，不符合EMC國際標準，在采用變頻器后，產(chǎn)生的傳導和輻射干擾，往往導致控制系統(tǒng)工作異常，采取必要措施。
