Diagram of interrupter of circuit breaker in 330kv switchyard

A very specific and technical question!

Here is a simplified diagram of an interrupter in a 330kV circuit breaker in a switchyard:

Here's a brief explanation of each component:

1. Live Tank: The live tank is the main housing of the circuit breaker, which contains the electrical insulation and the interrupter.
2. Interrupter (Arc Chute): The interrupter is the heart of the circuit breaker, responsible for interrupting the electrical current. It consists of a metal tube with a narrow opening at the bottom, which helps to extinguish the arc.
3. Arc Extinction (Arc Quench): The arc extinction system is designed to quickly extinguish the arc that forms when the circuit breaker interrupts the current. This is achieved by injecting a small amount of gas (e.g., SF6) into the arc, which helps to cool and dissipate the energy.
4. Contact System: The contact system consists of moving and fixed contacts that make and break the electrical circuit. The moving contacts are typically spring-loaded and are designed to move quickly and smoothly to minimize arcing.
5. Operating Mechanism: The operating mechanism is responsible for actuating the circuit breaker. This typically involves a solenoid, spring, and other components that work together to move the moving contacts and interrupt the current.

Please note that this is a highly simplified diagram, and actual circuit breakers may have additional components or more complex designs. Additionally, the specific design and components may vary depending on the manufacturer and the specific application.
