电气道岔的基本功能为转换、核对、锁闭和显示,其锁闭机构分为in-out方式和交叉锁闭方式。日本既有线主要采用NS型电气道岔,与新干线所用T型道岔的锁闭机构相比较,NS型道岔难以采用缓冲机构。因此,需为既有线开发新形式的缓冲锁闭机构,该机构能实现缓冲锁闭和强制解锁功能。为验证新
The basic functions of electrical switches for conversion, check, lock and display, the locking mechanism is divided into in-out way and cross-lock mode. The existing Japanese lines mainly adopt NS-type electrical switches. Compared with the locking mechanism of the T-type switches used in the Shinkansen, it is difficult to adopt a buffer mechanism for the NS-type switches. Therefore, it is necessary to develop a new form of buffer lock mechanism for the existing line, which can realize the buffering lock and forcibly unlocking functions. For verification new
