摘　　要：主要介绍在大包线电气化改造工程中,地方电力资源不具备两路220 kV独立电源引入牵引变电所的情况下采用"手拉手"电源供电方式,对"手拉手"电源供电方式在经济性和可靠性两个方面的优越性进行论证,该种形式的电源供电方式具有结构简单、投资省、可靠性高等优点,是外部电源稀缺的情况下对牵引变电所实现两路电源供电的理想方法。In the electrification renovation project of Datong-Baotou Railway,the 'hand in hand' power supply mode was adopted because the local power sources didn't have two 220kV independent power supplies which should access to the traction substation.In this paper,the superiorities on the economic efficiency and reliability of 'hand in hand' power supply mode are demonstrated.The paper thinks that: there are many advantages in this kind of power supply mode,such as simple structure,low investment and high reliability.So it is the ideal way to achieve two-way power supplies for the traction substation in the case of the scarcity of external power sources.
