lengthening and splitting the arc.
Construction
In the Air Circuit Breakers, The Contory sections and Arc Extinction Take Place in Air At ATMOSPHERIC PRESSURI.
There are two sets of controls; main dach and arcing contacts.
is split by Arc Splitter Plates. The Arc is excitedlyd by lengthening, cooling and splitting.
Working Principle
Voltage by Mainly Three Different Ways,
. That Means Arc Voltage is increased.
Splitting up the arc into a number of Series arcs arcs the arc voltage.
Operation of Air Circuit Breaker
High Temperabure Plastics Reinforced with Glass Fiber and Ceramics Are Preferable Materials for Making Arc Chute.
Channel Project on the Arc Chute Wall. The length of the arc path increases the Arc Resistance.
Chute and Hence Individual ACB BREAKER SPLIT Arc Voltage Becomes High. The following color, make the overall arc voltage, Much Higher than the system voltage.
