摘要
新型电力机车在断电过关节式电分相时仍会产生过电压和拉弧现象,导致变电所跳闸,对机车安全运营构成严重影响,本文分析了电力机车断电过关节式电分相过程及过电压产生机理,并提出了利用阻容吸收回路抑制过电压的措施。
the overvoltage and arcing phenomenon of the new electric locomotive will still produce overvoltage and arc tension when the electric locomotive is broken through the joint type.It leads to the tripping of the substation,which has a serious influence on the safe operation of the locomotive.This paper analyzes the electric phase separation process and the overvoltage mechanism of the electric locomotive out of the joint type,and puts forward the suppression of over electricity using the resistance and capacity absorption loop.Pressure measures.
