摘要:
针对CRH5型动车组检修过程中，由于电气柜内电气元件端子压接不良等原因造成的短路或过流现象而导致的安全隐患等问题，采用更改端子结构以及利用红外热成像仪监测等方法，优化检修过程中对电气柜端子状态的检测方案。优化后方案可快速定位故障点，并能及时发现潜在安全隐患。通过优化后方案的实施，可大幅度降低车辆出厂故障率，对提升轨道交通装备的质量具有实际意义。
Abstracts:
During the maintenance of CRH5 EMU, serious safety hazards and other problems caused by the poor crimping of the electrical components in electrical cabinet are detected, which are the main reasons for short-circuit or over-current phenomenon. The status detection in the maintenance process can be optimized by adopting the modified terminal structure, applying the infrared thermal imager monitoring scheme and other methods. The optimization scheme can quickly locate the fault points and identify potential safety hazards in a timely manner, significantly reduce the vehicle factory failure rate with practical significance for the development of rail transit equipment.
