Duringopening operation (Fig.2), the Moving Contact along with thePuffer Cylinder is pulled down. The Fixed and Moving contactsget separated and arc is formed between fixed arcing contactand moving arcing contact. Motion of the Puffer Cylindercompresses SF6 gas against the Fixed Piston thus generating apowerful SF6 gas blast through the Nozzle over the arc. Aftertravelling through some distance, the dielectric strength of thegap is raised sufficiently to extinguish the arc. The reliability ofthe system is further enhanced by the single pressure dual flowpuffer interrupter, which reduces the number of moving parts andauxilliary systems in the circuit breaker. This principle is shownin Fig. 3.

SF6-Gas Circuit Breakers (GCB)For Out-Door Use (24 kV To 245 kV)Spring - Spring Operating MechanismCamTrip springRatchetClosing springLeverRatchet wheelThe spring-spring mechanism consists of two springs –Closing spring and Tripping spring. Closing spring is chargedthrough a motor driven cam, pawl and ratchet mechanism.Fig.4 shows the Breaker in Closed position (Closing springcharged)Closing-holdinglatchClosing triggerTrip-holdinglatchClosing coilInterrupterTrip coilTrip triggerFIG. 4 : Closed position (closing spring charged)Both closing spring and tripping spring are in charged position.The Tripping spring exerts counter clockwise torque on the lever. Atthis stage a locking device called ‘Trip Holding Latch’ avoids levermovement. When the trip coil is energized, the lever is released fromlocking device and rotates to attain the ‘Open’ position.Fig.5 shows the Breaker in Open positionFIG. 5 : Open position (closing spring charged)Tripping spring is in the relaxed condition. Closing spring exertscounter clockwise torque on the Cam and Ratchet wheel. Whenthe Closing coil is energized, the Cam rotates in counter clockwisedirection and in turn, the Lever is rotated clockwise. This levermotion closes the breaker and charges the Tripping spring at thesame time.Fig.6 shows Closed position ( Closing spring discharged )FIG. 6 : Closed position (closing spring discharged)Immediately after the breaker is closed, the spring charging motor gets activated. The closing spring is charged by the ratchet, linked to themotor. When the closing spring is fully charged the Limit Switch disconnects the supply to the motor and the closing-holding latch holds thecompressed spring energy till next discharge.
