摘要:
悬挂式单轨在站内发生牵引回流接地故障时会导致站内其他列车及相邻牵引变电所的断路器出现大范围跳闸现象。为了避免故障车辆对其他正常设备造成影响,便于维修人员快速准确地锁定故障范围,对传统接地保护装置进行了改进,取消列车上的接地过电压继电器,增加车载设备的差分电流检测装置,提出分层分级接地检测保护机制用于牵引回流接地故障的保护和快速定位。改进后的接地保护装置目前已经在试验线上进行运用,验证结果表明该保护机制能缩小故障影响范围,提高列车运行效率。
Abstract:
The traction power return grounding fault of suspended monorail in station will lead to large-scale tripping of circuit breakers of other trains and adjacent traction substations. In order to avoid the impact on other normal equipment, and help maintenance personnel locking the fault area quickly and accurately, improvements were made by canceling the grounding overvoltage relay on the train and increasing the differential current detection device of the on-board equipment. Meanwhile, a hierarchical grounding detection and protection mechanism was proposed for the protection and fast positioning of traction power return grounding fault. The improved grounding protection device has been used on the test line, and the verification results shows that the protection mechanism could reduce the impact of the fault and improve the efficiency of train operation.
