机车空调电源的比较与分析

Comparison and Analysis of Locomotive Air-conditioner Power Supply

总结了内燃机车、电力机车常用的空调电源的电路结构形式,简单探讨了空调电源电路的设计要点,并对电力机车的交直交与直交2种形式的空调电源电路进行了较为详细的对比分析,指出了各自的优点与不足;同时,介绍了机车空调电源变频调速的一般性原理,比较了定频与变频机车空调电源各自的优缺点。

Circuit structures of air-conditioner power supply for diesel locomotive and electric locomotive were summarized,and key points of air-conditioner power supply design were discussed.Two types of air-conditioner power supply circuit i.e.AC/DC/AC and DC/ AC convert circuit were compared in detail,advantages and defects of which were pointed out.At the same time,principle of air-conditioner variable frequency speed regulation was introduced,as well as the characteristics of fix-frequency and vari-frequency air-conditioner was compared.
