Vacuum Circuit Breaker. A Vacuum circuit breaker is a circuit which vacuum is used to extinct the arc. It has dielectric recovery character, excellent interruption and can interrupt the high frequency current which results from arc instability, superimposed on the line frequency current.Medium Voltage (MV) Vacuum Circuit Breakers Eaton's vacuum circuit breakers provide centralized control and protection of medium voltage power equipment and circuits in utility, industrial, commercial, mining and marine installations involving generators, motors, feeder circuits, and transmission and distribution lines. applications of vacuum circuit breakers
Description. 3AH5 vacuum circuit breakers control all switching duties in mediumvoltage systems. They are applicable for operation of e. g. overhead lines, cables, transformers, generators, capacitors, filter circuits, motors and reactors.
Vacuum circuit breaker has a high insulating medium for arc extinction as compared to the other circuit breaker. The pressure inside the vacuum interrupter is approximately 104 torrent and at this pressure, very few molecules are present in the interrupter. MV vacuum and SF6 gas circuit breakers for indoor and outdoor applications in primary and secondary power distribution networksapplications of vacuum circuit breakers Description. The newest vacuum circuit breaker generation of Siemens (called SION) was successfully introduced in January 2006. Since this time the SION VCB family has been developed as the global platform for all kinds of applications in medium voltage.
Vacuum circuit breakers With new improvements in vacuum breaker design, vacuum circuit breakers are becoming more common at the lower voltage ranges of transmission networks. Today they can handle voltages up to 252 kV but are still very expensive. applications of vacuum circuit breakers Applications of Vacuum Circuit Breaker The vacuum circuit breaker is today recognized as most reliable current interruption technology for medium voltage switchgear. It requires minimum maintenance compared to other circuit breaker technologies. In addition to standard mediumvoltage applications, vacuum circuit breakers also cover applications for specific requirements in the generator or rail fields, for example.
