Sf6 circuit breaker animation

Here is a simple animation of an SF6 circuit breaker:

Step 1: Normal Operation

The circuit breaker is in its normal operating state, with the contacts closed and the current flowing through the circuit.

Step 2: Fault Detection

A fault occurs in the circuit, such as a short circuit or a ground fault. The circuit breaker's fault detection system detects the fault and sends a signal to the breaker's control unit.

Step 3: Tripping

The control unit receives the fault signal and sends a trip signal to the breaker's tripping mechanism. The tripping mechanism opens the contacts, interrupting the current flow in the circuit.

Step 4: Arc Quenching

When the contacts open, an arc forms between the contacts. The SF6 gas inside the breaker's enclosure helps to quench the arc by interrupting the flow of ionized gas and reducing the arc's energy.

Step 5: Current Zero

The arc is extinguished, and the current flow in the circuit is interrupted. The breaker's contacts remain open until the fault is cleared and the circuit is safe to re-close.

Step 6: Re-Close

Once the fault is cleared, the breaker's control unit sends a re-close signal to the tripping mechanism. The tripping mechanism closes the contacts, and the circuit is re-established.

This is a simplified animation of the SF6 circuit breaker's operation. In reality, the breaker's operation is more complex and involves multiple components and systems working together to ensure safe and reliable operation.
