Sf6 Circuit Breaker Block Diagram. By means of the special spring catches hook the ropes to the circuit breaker hook to the special anchoring points provided in the structure and lift. Due to its low gaseous viscosity sf6 gas can efficiently transfer heat by convection.
Medium voltage circuit breakers air magnetic sf6 or vacuum type are designed to operate electrically. The only exception to the parallel wiring of contacts is the low gas auxiliary relay contact 63x in the figure. There is not a proper block diagram for sf6 circuit breaker but a layout is available for reference.
Next contact is the ma1 52 1.
This is accomplished by electrical components on the circuit breaker operating mechanism. This is a normally open contact of the power circuit breaker. 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. Sf1 circuit breakers fi xed version from 12 kv to 36 kv.
