以功率为1 800 kW的强迫风冷式制动电阻装置为例,对其散热性能进行预算,对电阻柜温度分布及流道进行分析,指出设计中应注意的问题。 Taking the forced air-cooled braking resistor device with a power of 1 800 kW as an example, the heat dissipation performance is estimated. The temperature distribution and flow path of the resistance cabinet are analyzed, and the problems that should be paid attention to in the design are pointed out.
