SS_(4B)型电力机车PDU受电弓升降保护装置的研究

Study about PDU Pantograph Lifting Protection Device of SS_(4B) Type Electric Locomotive

作为电力机车的关键部件,受电弓一旦发生故障往往会使得电力机车失去动力来源。本文就SS4B型电力机车的受电弓工作原理展开分析,并对PDU受电弓升降保护装置设计思路、PDU受电弓升降保护装置组及功能进行了详细论述,希望由此能够降低SS4B型电力机车受电弓故障发生几率,并同时为相关业内人士带来一定启发。

As a key part of electric locomotive,once the pantograph has problems,the electric locomotive will lose its energy source. Based on this situation,the working principle of pantograph for SS_(4B) electric loco-motive is analyzed in this paper,and the design idea of the lifting protection device for PDU pantograph,PDU pantograph lifting protection device unit and its functions are discussed in detail,with the hope that itcan reduce the failure probability of the pantograph of SS_(4B) electric locomotive and provide some inspira-tions for the people in relevant industries.
