摘　　要：给出了HXN3型内燃机车国产化制动电阻装置分压电阻计算和该装置风机电机在不同负载条件下运行范围的分析和计算;并且,通过试验的方法验证了匹配后制动电阻装置运行在不同负载条件下是安全的。在这个过程中还涉及到风机电机效率参数计算、风机组功率与转速的关系确定、空气密度对风机功率影响分析等。The shunt resistor calculation of domestic braking resistor and the operation range analysis of its blower motor under different load conditions are described.The test shows that the matched braking resistor can run safely under different load conditions.The calculation of blower-motor set efficiency data,the determination of relation between blower-motor set power and speed,and the air density effect on blower power are also involved in the process.
