电气化铁道 AT 供电方式“V”型天窗开设的研究

Study on Opening “V” Window on Electrified Railways with AT Power Supply System

为提高运输能力，探讨了电气化铁路ＡＴ（２×２５ｋＶ）供电方式双线区段上开设“Ｖ”型天窗的可能性。为此，建立了用于理论分析的数学模型，完成了感应电压计算和实测。结果表明，为确保人身安全，在采用建议的必要措施后方可开设“Ｖ”型天窗。

This paper,studies the possibilty of opening “V” window on double line electrified railways, with AT(2×25kV) power supply system in order to increase transport capacity.Hence a calculation model is established for theoretical analysis and calculation and measurement of induction voltage are carried out.The results have demonstrated that some necessary safety measures should be taken for protection of people before “V” window can be opened.
