Types of Circuit Breakers : Working, Advantages and Disadvantages

AdvantagesTerminologyDesignPropertiesExampleMechanismApplicationsOperationIntroductionThey work smoothly as long as the appliances have sufficiently resistant and do not cause any over current or voltage. The reasons for heating up the wires are too much charge flowing through the circuit or short circuiting or sudden connection of the hot end wire to the ground wire would heat up the wires, causing fire. The circuit breaker will prevent such situations which simply cut off the remaining circuit. The negative ions which are formed will be much heavier than a free electron. Therefore, when compared with other common gases overall mobility of the charged particle in the Sulfr hexafluoride gas is much less. The mobility of charged particles is majorly responsible for conducting current through a gas. Hence, for heavier and less mobile charged particles in Sulfr hexafluoride gas, it acquires very high dielectric strength. This gas good heat transfer property because of low gaseous viscosity. insulating gas is 100 times more effective in arc quenching media than air circuit breaker. It is used for both medium and high voltage electrical power system from 33KV to 800KV. A Vacuum circuit breaker is a circuit which vacuum is used to extinct the arc. It has dielectric recovery character, excellent interruption and can interrupt the high frequency current which results from arc instability, superimposed on the line frequency current.Get price
