摘要
Abstract
This paper introduces two kinds of arc suppression methods used in track unilateral connecting device:the discharge gap and GTO. The discharge gap arc suppression is influenced by the environment and cannot be controlled precisely, while GTO arc suppression can control breakover, but cannot control shutdown, which results in permanent reverse connection of unilateral connecting device and in poor protection of stray current. By analyzing process and equivalent circuit, a new intelligent arc-suppression device is proposed to fulfill shutdown control of unilateral connecting device and prevention of permanent reverse connection.关键词
