CRH380A动车组空调故障分析与检修方案优化
摘 要
安全生产是经济社会运行、人民生命财产的生命线,是铁路企业的生存线。高铁在国民经济及国民生活中扮演着越来越重要的角色,保证高铁运输的顺利和安全非常关键。高铁动车组空调失效虽发生概率小,但一旦发生,特别是在炎热的夏季,车厢内的温度会迅速升高,短时间未处置好,旅客会感到身体不适,严重时还可能会引发旅客群体情绪波动,将造成特别大的负面影响,甚至威胁到旅客生命安全。为了更好地服务旅客和保证旅客安全,国铁集团高度重视动车组空调失效的应急处置,多次修订旅客列车空调失效应急处置办法。本文结合运输实际,重点从调度指挥及提质高效方面入手,优化现行高铁动车组空调失效应急处置办法,压缩动车组空调失效非正常处置的时间,减少空调失效的负面影响,保证高铁运输的服务品质,维护高铁运输的社会形象。因此对于空调故障的统计分析尤为重要本文针对CRH380A动车组的空调系统，主要介绍了中国和谐号CRH380A动车组空调系统的维护，并着重分析了动车组空调装置的应用与运行过程中可能出现的各种故障。而在故障发生时应当由列车长和随车机械师按照相关规定及时采取相应的处理措施，以保证列车的正常运行。

Abstract
Safety production is the lifeline of economic and social operation, people's life and property, and the survival line of railway enterprises. High speed railway plays an increasingly important role in the national economy and national life. It is very important to ensure the smooth and safe transportation of high-speed railway. Although the probability of air conditioning failure is small, once it happens, especially in the hot summer, the temperature in the carriage will rise rapidly. If it is not handled properly for a short time, the passengers will feel unwell. If it is serious, it may also cause the emotional fluctuation of the passenger group, which will cause a great negative impact and even threaten the safety of the passengers. In order to better serve passengers and ensure the safety of passengers, the State Railway Group attaches great importance to the emergency disposal of air conditioning failure of EMUs, and has revised the emergency disposal methods for air conditioning failure of passenger trains for many times. Combined with the actual transportation, this paper focuses on the aspects of dispatching command and improving quality and efficiency, optimizes the current emergency disposal method for air conditioning failure of high-speed railway EMUs, compresses the abnormal disposal time of air conditioning failure of EMUs, reduces the negative impact of air conditioning failure, ensures the service quality of high-speed railway transportation, and maintains the social image of high-speed railway transportation. Therefore, the statistical analysis of air-conditioning failure is particularly important. This paper mainly introduces the maintenance of air-conditioning system of crh380a EMU, and focuses on the application of air-conditioning device of EMU and various possible failures during operation. When the fault occurs, the conductor and on-board mechanic should take corresponding measures in time according to relevant regulations to ensure the normal operation of the train.
Key words: crh380a EMU air conditioning; air conditioning system maintenance; overhaul scheme optimization
