Apparatus for section of electric automobile

전차선 섹션 보호장치에 관한 연구

For constant operation, Electric Railway System has many electrically divided parts of the trolley lines to avoid error spreading. FRP-Section have a role to divide Catenary trolley lines electrically. If one electric train approach to the section at the same time with partial power failure, the pantograph of train can make a short circuit with supplied part to failure part. Electric arc induced with this switching effect, can break FRP-section, and there are such error cases. In this study, we propose one method to prevent FRP-section breakdown from these reason, with detecting sensor at the sectional position.
