电力机车电工电子设备的环境适应性与使用可靠性

ENVIRONMENTAL SUITABILITY AND ACHIEVED RELIABILITY OF ELECTRIC AND ELECTRONIC EQUIPMENTS FOR ELECTRIC LOCOMOTIVES

本文侧重分析了电力机车主回路系统的环境适应性与使用可靠性之间的关系,并围绕主要的气候环境参数和机械环境参数,对各个子系统加以阐述。以简单示例,对地面车辆使用的电工电子设备通常涉及的振动、冲击、温度、湿度等综合环境条件与系统使用可靠度作了分析。在提出分析方法的同时说明了环境适应性对铁路运输安全的重要意义。

This paper gives an emphatical analysis to the relations between the environmental suitability and the achieved reliability of the main circuit system for electric locomotives. The analysis is centered on the main climatic parameters and machinery parameters of the system's environment, and each subsystem is separately described, too. A simple example is taken as analysing the system achieved reliability and the overall environmental conditions such as vibration, shock, temperature and humidity, which usually concern the electric and electronic equipments used on the ground rolling stock. Besides the analytical method being given out, the importance of the environmental suitability to railway transport safety is made explicit.
