Low Oil Circuit Breaker Diagram. Oil blast circuit breaker the fk 255 is a tri jle pole single throw oil circuit breaker enclosed in a common tank. Therefore it is also known as the arcing chamber.
The quantity of oil requires in bulk oil circuit breaker depends on the system voltage. The construction of a low oil circuit breaker is shown in the figure. An oil circuit breaker is one kind of circuit breaker where the insulating oil can be used as an arc quenching medium.
Whenever there is a separation of current carrying contacts in the oil the arc in circuit breaker is initialized at the moment of separation of contacts and due to this arc the oil is vaporized and decomposed in mostly hydrogen gas and.
An oil circuit breaker is one kind of circuit breaker where the insulating oil can be used as an arc quenching medium. Therefore it is also known as the arcing chamber. Once the fault occurs within the system then circuit breaker contacts will be separated and the arc will be struck among the contacts. A breaker which uses a large quantity of oil for arc extinction is called a bulk oil circuit breaker.
