A high-voltage circuit breaker, also known as a high-voltage switch, is an essential electrical device used to open or close circuits under high voltage conditions. It can handle both no-load and load currents, and it automatically interrupts the circuit when there are overloads or short-circuit faults by working in conjunction with relay protection systems. This ensures the safety and stability of the power system.
These circuit breakers are designed with advanced arc-extinguishing mechanisms and strong current-breaking capabilities. They come in various types, including oil circuit breakers (such as multi-oil and minimum-oil types), sulfur hexafluoride (SF6) circuit breakers, vacuum circuit breakers, and air-blast circuit breakers. Each type has its own advantages and is suitable for different applications depending on the voltage level, environment, and system requirements.

Oil circuit breakers, for example, use insulating oil to quench the electric arc that forms during switching. SF6 circuit breakers are widely used due to their excellent insulation and arc-quenching properties, making them ideal for high-voltage transmission systems. Vacuum circuit breakers, on the other hand, are known for their fast operation and long service life, often used in medium-voltage applications. Air-blast circuit breakers rely on compressed air to extinguish arcs, offering reliable performance in certain industrial settings.
