摘要
为了达到指导变频器设计和应用的目的,本文经过严格的数学推导,得出上电缓冲电阻的参数的计算公式,并根据能量守恒原则,建立热能方程,分析出上电时电阻的温升,以及断电降温时间。
In order to achieve frequency converter design and Application Guide, parameter formula of current limiting resistor is deduced by strict mathematical method In this paper. Heat equation is established, resistance temperature and cooling time are calculated according to the principle of conservation of energy.
