大秦线牵引变电所存在的问题及解决方案

Problems Existed in Traction Substations of Datong-Qinhuangdao Railway Line and Their Resolution Plan

以大秦线铁路牵引变电所为例,通过列举牵引变电所主变压器、110kV进线隔开、微保综自等变配电设备的运行现状和存在的主要问题,阐述了制约牵引变电所安全稳定运行的诸多不利因素及可能对设备安全造成的严重危害。并根据变配电设备的运行特点,结合现场运行实际情况,对存在的问题进行相应研究探讨,提出解决方案,制定预防措施,从而改善牵引变配电设备的运行环境,确保牵引变电所的安全稳定运行。

Taking the traction substation of Datong-Qinhuangdao railway line as an example, by presentation of the operation status and problems of traction transformers, 110 kV incoming disconnectors, micro-computer protection and integrated automation equipment in traction substation, the paper illustrates many unfavorable factors constraining the safe and reliable operating of traction substation or causing severe damage of the equipment safety. And on basis of operating characteristics of substation and distribution station, with reference of actual situations of site operation, the researches and study of the problems have been conducted accordingly, resolution schemes have been put forward, preventive measures have been established so as to improve the operating environment of traction substation equipment and guarantee the safe and reliable operating of the traction substation.
