The Risk of Fire and Maintenance Associated with The Use of Oil is Eliminated.
Mechanical Stresses that are set up due to gas aND OIL MOVEMENT are eliminated.
The Cost of Regular Oil Replacement Due to Deterioration of Oil with SUCCESSIVE BREAKINGOPENS IS ABSENT.
Plain Air Circuit Breakers
Air Blast Circuit Breakers
Plain Air Circuit Breakers FURTHER Can Be Subdivided Into the Follow Categories:
Plain break type
Magnetic Blow-out Type
Arc Chute Type
Upwards by the convection Currents caused by the heading of Air During Arcing and the Internet of Magnetic and Electric Fields.
Adjacent Metal Parts.
Chutes where the arc is lengthened, cooled, and quenchd.
Arc Chute Type: The Construction of An Air Circuit Breaker (Arc-Chute Type) use for low and medium voltage is shown in the food.
. Here blow-outs consist of Steel inserts in the arcing chutes.
Is queenched by lengthening and exceessive power loss. The main privem in this type of circuit breaker is inchamedience the eoldromagnetic fields are we week.
In the OCCURREANCE of a fault, the main contacts seleite first, and the current is shifted to the arcing controls. Now the arcing contactions, and the arc is struck to betWeen THETWEENTWEEN THEA
The Protection Settings for a Circuit Whild Should Be Known are as follows:
Long time delay: The Long-Time Delay Should be Adjusted in Such A Manner that the inrush Current Should Should TO PASS Throughs Thrinker Without Tripping WHENG.
