Sf6 Circuit Breaker Block Diagram. Modern power circuit breakers employ sulfur hexa flouride sf6 gas to extinguish an arc. This is done to monitor if the auxiliary contacts no and nc contacts of the power circuit breaker are in normal position.
Sf circuit breakers one range of comprehensive and proven three pole circuit breaker units for indoor installation using sf6 technology. This circuit breaker range meets iec standard 62271 100. Due to these unique properties of this gas sf6 circuit breaker is used in a complete range of medium voltage and high voltage electrical power system.
The only exception to the parallel wiring of contacts is the low gas auxiliary relay contact 63x in the figure.
The sf6 circuit breaker is mainly divided into three types. Next contact is the ma1 52 1. These electrical components operate cams wheels rollers and latches to charge close and open the breaker. The sf6 circuit breaker is mainly divided into three types.
