Why Air Circuit Breakers Are Better Than Oil Circuit Breakers?
Air circuit breakers are open and operate at atmospheric pressure, making them easier to adjust and modify. They also require less maintenance and are more cost-effective than oil circuit breakers. Air circuit breakers work well for industrial plants & can provide defensive barriers to electrical machines such as transformers & generators. They can even raise the resistance power by splitting, cooling & lengthening the arc.
An air circuit breaker has two pairs of contacts. The main pair carries current during normal operation and is made of copper metal. The second pair is called the arcing contact and is made of carbon. These contacts stay in touch with each other when the main contacts open. This creates a conductive path and prevents arcing. Unlike the oil circuit breakers, air circuit breakers do not have any risks of fire or explosion. They are also less prone to mechanical stress and don’t require the same amount of maintenance as their oil counterparts. The global air circuit breaker market is expected to grow at a rapid pace in the future, especially in Asia Pacific. The rising adoption of smart grids in the region underscores the need for reliable and durable power devices such as ACBs. The high breaking capacity of these devices will reduce energy losses during faults and enhance power quality, which aligns with the region’s progressive initiatives.
Air circuit breakers use atmospheric air as a dielectric and can handle high fault currents. This makes them a more cost-effective alternative to oil or SF6-based circuit breakers. They also require less maintenance than other types of switchgears. The operating principle of an ACB is to force the arc into an insulating lamella or a chamber called the ‘arc chute’. The arc will then cool and lengthen until it is no longer able to maintain itself, at which point it will be extinguished. This is a more economical and safer option than using oil, as the risk of an oil fire is considerably higher in a switchgear with an oil circuit breaker. Increasing energy efficiency and focus on grid reliability are driving the demand for modern ACBs. As such, the ACB market is expected to continue to grow over the forecast period.
Air circuit breakers are used as a way to protect electrical circuits from high current. They have a unique design that allows them to be more versatile than other types of circuit breakers. Specifically, they can be used in various applications including industrial and mining businesses.
They operate in the same fashion as MCCBs, but they also have a few distinct differences. First, they have a mechanism that is used to charge the internal springs. This mechanism is usually located on the front of the unit and will have a handle that is pulled down several times to crank the springs up to a specific tension. When a fault is detected, the primary contacts will separate and current will flow to the arcing contacts.
The arc will then be drawn upward by electromagnetic forces and heat action until it enters the arc chute. The arc will then be cooled and extinguished. This process is much quicker than the process of resetting a fuse, which can be extremely dangerous and lead to an oil fire.
