变频器的维护及保养就显得尤为重要，那怎么样才可以降低故障率，让变频器的度过夏天，减少客户损失呢?因此，现在主要从以下几方面简单介绍：

一、夏季变频器维修保养注意这几点，适宜的温度，湿度，通风，无尘无干扰，对变频器进行内部、外部的清扫。

二、直接影响变频器散热的主要方面?

1、风扇运转保护，变频器的内装风扇是箱体内部散热的主要手段，它将保证控制电路的正常工作。所以，如果风扇运转不正常，应立即进行维护。

2、逆变模块散热板的过热保护逆变模块是变频器内发生热量的主要部件，也是变频器中*重要而又*脆弱的部件。所以，各变频器都在散热板上配置了过热保护器件。

3、冷却风道的入口和出口不得堵塞，环境温度也可能高于变频器的允许值。有针对性地提出了一些解决问题的方法及改进的建议，对于变频器在实际工程中的应用有的参考价值。

4、干扰问题要注意变频器对微机控制板的干扰问题。用户自己设计的微机控制板工艺水平差，不符合EMC国际标准，在采用变频器后，产生的传导和辐射干扰，往往导致控制系统工作异常，采取必要措施。
