Outdoor switches for railway lines - 2

Our good and successful cooperation with DeutscheBahn AG already began in the fifties. Over the course of time more and more importance was attached to the reliability of traction power sup- ply which made it necessary to design switching devices with new technologies. Initial efforts already commenced in the Sixties in the field of vacuum tech- nology and this led to the first outdoor line sectiona- lizers* with vacuum interrupter. Based on a very intensive cooperation with DB (German Rail) we were able to install an outdoor switch disconnector FLa in the railway network for trial...

The trend is to use a vacuumBasic research on switching in a vacuum began inGermany during the Seventies. At this time low-oil switches had become firmly established in medium voltage networks, based on their reliable operation over decades, and were accepted by users as relia- ble devices. In laboratory tests it proved that the vacuum switches were superior by far to the con- ventionally applied switching principles. All these requirements necessitate a switching unitwith electrical properties that preferably do not change throughout its service life. The vacuum inter- rupter is...

Design of switch The types of outdoor switch-disconnector and outdoordisconnecting switch mostly differ through the appli- cation of different cast-resin insulators (length and height of creepage path) as well as in the baseframes (U-profile and sheet-metal frame). Optionally its possible to equip the switches with, silicon combined insulators. > General Design These Driescher outdoor switches are specially desi-gned for railway applications. They meet the specifi- cations according to the EN 50152-2. The 1-pole and 2-pole switches are designed for a rated voltage range from 15 kV to 29 kV...
