Study On The Transformation Of Traction Power Supply Equipment From Mengmiao To Lujiashan Section Of Beijing Guangzhou Line

Beijing-guangzhou line has the longest period of the traction power supply equipment operation has amounted to 24 years,low standard of existing equipment,aging is serious,the power supply capacity is saturated,the beijing-guangzhou line freight capacity after strengthening,must be corresponding transform both the traction power supply facilities,improve the capability of power supply.On the issue,the author of the traction power supply equipment present situation from Mengmiao to Lujiashan section of beijing-guangzhou line has carried on the thorough research and access to a lot of practical engineering data,the traction power supply equipment modification from Mengmiao to Lujiashan section of beijing-guangzhou line were studied and discussed in detail.Paper,first of all,from a technical point of research and exploration of the traction power supply equipment modification is feasible and applicability,and through the research of traction substation load operation,calibration traction transformer installed capacity,optimize the power supply system,traction substation power supply in each arm central add insulation anchor segment joints and electric isolation switch into remote,adhere to the principle of advanced technology,reasonable economy under the traction power supply equipment reform from Mengmiao to Lujiashan section of beijing-guangzhou line put forward the reasonable technical transformation scheme,the second reference related norm,calculated the economic indicators.Through the research of this subject,it is feasible to implement the transformation of the traction power supply equipment from Mengmiao to Lujiashan section of beijing-guangzhou line.After transforming the traction power supply equipment can greatly improve the power supply ability,compression equipment failure rate,greatly release cargo capacity makes both the beijing-guangzhou line,interval through capacity and transportation capacity can meet the demand of passenger and cargo traffic volume,along to the local economy and the overall national economic development has important significance.
