A circuit breaker includes a slotted magnetic device having a plurality of spaced slotted conductive plates and a moving contact arm positioned within the slot when the circuit breaker is in a closed circuit position so that current flowing through the contact arm has a component in a vertical ...
Test Analysis of Commutating Process for Hybrid Current-limiting Circuit Breakers with High Rising Rate Current A novel hybrid current-limiting circuit breaker based on high speed electro-magnetic driven switch and bi-directional thyristor switch is presented.A 3 kA/... C Wang,J Zhuang,X Zhang,...
Air circuit breakers from the Begrenzerart with open blaster There are described a power switch and a method for forming the current-limiting circuit breaker. The circuit breaker includes a carriage assembly to deliv... M Rane,S Das,GC Sisson 被引量: 0发表: 2015年 SELF-ALIGNING PORTABLE ACT...
The topology consists of several units which are divided into two classes: main circuit breaker (MCB) and branch circuit breakers (BCBs). The number of inductor branches can be flexibly selected to enhance the current limiting effect. The CL-DCCB can start current limiting operation when a ...
For example, a commercially practical current limiting circuit breaker (a) must be repetitively operable at its maximum short circuit interrupting rating without repair of replacement of parts (This requirement precludes the use of fuses, fused switches, or fused circuit breakers for achieving current ...
PROBLEM TO BE SOLVED: To provide a current-limiting breaking device, in which a big current- limiting effect can be obtained and stationary loss can be reduced, and which can be applied to a high voltage, heavy current circuit and can be made compact as well as a low can be materialized...
