| 摘 要： | 煤矿井下要求电气元件必须满足国家安全及防爆标准要求,电气元件均要安装在封闭的防爆箱体里,导致发热量大。变频器这样的电气元件在箱体里,热量无法及时散出,影响电气元件的使用寿命甚至导致损坏,所以变频器的冷却计算及冷却部件的选择极为重要。介绍了计算的方法及元器件的选择方法。

| Abstract: | Underground electrical components required,must meet the requirements of national security and standards for explosion proof electrical components are to be installed in a closed explosion-proof box,the then lead to heat large-the drive that electrical components in the box,the heat can not shed in time,affect the life of electrical components or even cause damage,so the calculation of the drive’s cooling and cooling critical components of choice,this paper introduces the calculation method and components selection. |
