基于电子开关的地面自动过分相装置技术研究

Researches on Electronic Switch based Technology for Ground Automatic Phase Breaking Devices

列车安全可靠地通过电气化铁路分相区是国内外很多专家和学者一直致力于研究的问题,其中基于高压大功率半导体电子开关的地面自动过分相技术是近年来的研究热点。本文研究电气化铁路电子开关过分相系统的系统构成、工作原理以及不同工作电压适应性问题,最后通过现场试验证明电子开关过分相技术的有效性。

The issue for the train’s safely and reliably passing through of phase breaks of electrified railway is an important issue to which researches have been making constantly by the experts and scholars from the home and abroad, one of the phase breaking technologies by application of high voltage high power semi-conductor electronic switch is a hotspot of researches in recent years. In this paper, the researches are made for the issues of system composition, working principles and adaptability under different working voltages of electronic switch based phase breaking system for electrified railway, and the effectiveness of electronic switch based phase breaking technology has been verified by the site test.
