Synchronous MV circuit-breaker with magnetic drive and electronic control

摘要

New synchronous circuit-breakers developed by ABB can be fully integrated in medium-voltage switchgear in order to provide synchronous functionality at the distribution level. Equipped with fully configurable software, such circuit-breakers offer flexible solutions that can be used in all types of network, eg to reduce switching transients. They extend the range of synchronous operation from capacitor bank switching to all distribution circuit-breaker applications, including the synchronous interruption of short-circuit currents. Advantages of the new breakers include high quality and reliability over their service life, reduced maintenance, improved availability and service continuity, as well as a potential cost-saving in the increasing number of applications in which power quality is important. By allowing networks to be simplified, they also help to reduce the overall power system costs.
