自20世纪90年代起,我国开始研究空调电源,并取得了阶段性成果,但是依然存在散热性、可靠性和控制性差等缺点,机车空调在频繁的使用过程中故障时有发生。本文深入研究内容机车空调电源的常见故障、存在原因及解决的对策,旨在通过分析为我国内燃机车的科学运用及行车安全提供理论指导及借鉴。 Since the 1990s, China started to study the power supply of air conditioners and achieved the phased results. However, there are still some shortcomings such as heat dissipation, reliability and poor controllability. Locomotive air conditioners often occur during frequent use. This article delves into the common faults, causes and solutions of the locomotive AC power supply, and aims to provide theoretical guidance and reference for the scientific use of locomotives and traffic safety in our country through analysis.
