?在使用的過程中，變頻器的性能會受到以下因素的影響：一是溫度，二是濕度，三是振動，四是粉塵，五是腐蝕性氣體，以上因素都會導(dǎo)致變頻器的性能發(fā)生變化。如果變頻器的維護(hù)與保養(yǎng)合理，就可以充分發(fā)揮出變頻器的作用，還可以延長變頻器的使用壽命，降低變頻器故障的發(fā)生率，進(jìn)而降低變頻器故障的維修費(fèi)用。但是，如果工作人員沒有認(rèn)識到變頻器維護(hù)與保養(yǎng)的重要性，不注重變頻器的維護(hù)與保養(yǎng)，就會導(dǎo)致變頻器出現(xiàn)故障，而且變頻器的應(yīng)用壽命也會受到很大的影響。由此可以看出，變頻器的維護(hù)與保養(yǎng)是必不可少的。對于使用時間比較長的變頻器，工作人員可以從外向內(nèi)展開日常檢查，主要檢查變頻器的運(yùn)行狀態(tài)是否正常。除此之外，工作人員還需要對變頻器展開以下檢查：一是檢查變頻器運(yùn)行狀態(tài)下的溫度是否正常。通常情況下，變頻器的運(yùn)行溫度不能超過25攝氏度。二是檢查變頻器顯示板是否可以清晰的顯示信息。三是變頻器的電壓和頻率是否正常，四是變頻器的風(fēng)扇是否運(yùn)轉(zhuǎn)正常，只有保證變頻器風(fēng)扇運(yùn)轉(zhuǎn)的正常才能降低變頻器運(yùn)行溫度，否則變頻器運(yùn)行時間越長，溫度就會越高。五是變頻器的運(yùn)行的過程中是否出現(xiàn)過預(yù)警顯示。六是檢查變頻器是否出現(xiàn)異味。七是檢查變頻器的電壓是否控制在合理的范圍內(nèi)，如果變頻器的電壓數(shù)值過大，即便變頻器不在運(yùn)行的狀態(tài)下，過高的電壓也會損壞變頻器。工作人員一定要結(jié)合變頻器運(yùn)行的實(shí)際情況合理制定變頻器維修與保養(yǎng)方案，定期開展變頻器的維修與保養(yǎng)，在開展大型變頻器維修時一定要注重細(xì)節(jié)，特別要檢查日常維修時無法巡視到的位置。事實(shí)上，變頻器自身具有保護(hù)功能，主要包括以下環(huán)節(jié)：一是側(cè)接地保護(hù)，二是短路保護(hù)，三是電流限制，四是逆變器過熱，五是逆變器過載，六是自診斷功能，七是報警警告功能。工作人員必須對變頻器的這些特點(diǎn)和功能有充分的了解，這樣可以更好的保證變頻器維修和保養(yǎng)方案的合理性。
