Understanding Construction Terms: How an Oil Breaker Works
What is an Oil Breaker?
An oil breaker, also known as an oil circuit breaker, is a type of circuit breaker that uses oil as an arc extinguishing medium to interrupt the flow of current in an electrical circuit. It is commonly used in high-voltage applications to provide protection against overcurrent and short circuits.
Components of an Oil Breaker
An oil circuit breaker consists of the following main components:

- Arc chute
- Oil tank
- Operating mechanism
- Oil flow regulator
How Does an Oil Breaker Work?
Arc Interruption Process
When a fault occurs in the electrical circuit, the contacts of the oil breaker open to interrupt the current flow. As the contacts separate, an arc is formed between them due to the ionization of the medium. The arc generates heat and gases, which need to be extinguished to prevent further damage.
Arc Extinction with Oil
As the arc is produced, the oil within the breaker comes into contact with the arc and vaporizes rapidly. The vaporized oil decomposes into hydrogen and carbon monoxide gases, which quickly cool and extinguish the arc. The oil also provides insulation and helps in quenching the arc efficiently.
