对受电弓离线产生过电压的分析

随着我国高速铁路的发展，电力机车的速度在不断地提高，相伴随的受电弓脱离接触网的情况也越来越频繁，这种情况会严重制约高速铁路的发展。概述了受电弓脱离接触网后产生的危害，并从电气的角度分析了受电弓离线时产生过电压的机理。

Analyzing the Over-voltage Caused by Contact Loss of Pantograph From Catenary

Along with the development of China high-speed railway, the speed of electric locomotive is becoming higher and higher. As a result, the problem that pantograph deviates from catenary happens more and more frequently. This situation will restrict the development of high-speed railway. This paper summarizes the harm that could be caused by the contact loss of pantograph from catenary and analyzes the reason of the over-vohage caused by the contact loss.
