What Is Oil Circuit Breaker

By | March 26, 2023

In a modern electrical system, an oil circuit breaker is an important piece of equipment responsible for keeping the power running safely and efficiently. As an operator of a large industrial plant, it's essential to understand what this equipment is, how it works, and why it's important for your operations.

An oil circuit breaker is a type of switching device used to close and open an electrical circuit. This breakers electrical contacts are separated by an oil-filled tank, which acts as an arc extinguisher. The oil helps to quickly clear any current that might persist in the circuit after the contacts are opened. This ability to quickly kill off any arcs and prevent surges in energy makes oil circuit breaker an ideal choice for today’s high-voltage applications.

When it comes to safety and reliability, oil circuit breakers are a must-have in any electrical system. Unlike their air circuit counterparts, they don’t generate any sparks or arcs during operation, making them much safer to use. Additionally, they provide better control over the timing of the circuit closure/opening, ensuring that the power is cut off/on in a timely manner and preventing any damage due to extended energization.

Oil circuit breakers also offer increased reliability and endurance over their air circuit counterparts. Where air circuit breakers are prone to wear and tear due to their contacts wearing out, oil circuit breakers have a much longer lifespan. In addition, their contacts are sealed to protect against dust and other contaminants, further increasing their durability and improving their performance.

Finally, oil circuit breakers are easy to maintain, saving you time and money. Their parts are easily replaced, and their contact surfaces are designed to reduce erosion and corrosion, meaning that you won't need to carry out frequent repairs as you would with air circuit breakers.

Overall, it's clear to see why oil circuit breakers are such an important part of any modern electrical system. Their ability to quickly extinguish arcs, make them a safe and reliable option, while their ability to withstand higher current loads and extend their lifespan makes them a cost-effective choice. With regular maintenance and proper installation, oil circuit breakers can provide your industrial plant with reliable and efficient power for years to come.
