摘要
由于鹤矿集团铁路运输部直流牵引供电线路延长,变电所脱扣器保护不能满足线路全长,存在保护死区导致保护误动和拒动情况较多,造成生产不便和电气设备烧损。经机电处、铁路运输部、诚基水电热力公司、北京美兰尼尔有限公司共同研制成DPU-11直流牵引系统保护测控装置并现场进行了试验,对该装置性能进行分析。
Because the crane ore group railroad department of transportation cocurrent hauling supply line lengthens, the transformer substation trip protection cannot satisfy the line span, the existence protection dead area causes the protection to move and resists to move the situation by mistake to be many, creates the production inconvenient and the electrical equipment loss by burning. After mechanical and electrical place, the railroad department of transportation, the honest base water and electricity thermal energy company, Beijing Meilan Neil Iimited Company developed the DPU-11 cocurrent hauling system protection observation installment together and have carried on the experiment on the spot, and carried on the analysis to the equipment performance.
