Operating Duties Of Circuit Breaker. Circuit Breakers are the switching and current interrupting devices. CBs are necessary at every switching point in the substation. Fault current interruption. Arc extinction. Speed of operation. Basically a circuit breaker(CB) comprises of a set of fixed and movable contacts.
When the circuit breaker needs to open, the stored energy in the spring is released, causing rapid separation of the contacts. Similarly, when closing the breaker, the spring is again charged, providing the necessary force to bring the contacts together. 3. Magnetic Circuit Breakers
The operation of a vacuum circuit breaker is based on the principle of creating a vacuum inside the interrupter chamber. When a fault occurs, the contacts of the circuit breaker are forced apart, creating an arc. The vacuum inside the interrupter chamber helps to extinguish this arc by isolating the contacts from the surrounding air.
The design of the circuit breaker enables it to detect these conditions and disconnect to prevent damage. The primary components of a circuit breaker include: Contacts: These are conductive elements within the breaker that form the electrical path. A pair of contacts usually has a fixed and a moving contact.
The main aim of a circuit breaker is to extinguish the arc within the shortest possible time. Arc Extends as Contact Move. Arc is resistive - Thermal heat energy input – Negative “Resistance” Characteristics. Arc Extinguishes at Current Zero. Opening CB = Current Zero at this instant. = Voltage is at max. (peak) value.
