Advantages of Vacuum Circuit Breakers Explained Technically!

The vacuum circuit breaker is an innovative and advanced type of electrical circuit breaker that is gaining popularity in the electrical industry. These circuit breakers offer numerous advantages over traditional air circuit breakers making them a preferred choice for many electrical applications. From their long service life and high reliability to their low maintenance requirements and ability to operate in extreme temperatures, vacuum circuit breakers are an excellent investment for those looking to upgrade their electrical systems. In this article, we will take a closer look at the many advantages of vacuum circuit breakers and why they are the preferred choice for many electrical applications.

Advantages of Vacuum Circuit Breakers

The major advantages of vacuum circuit breakers are:

1. High reliability

Vacuum circuit breakers are highly reliable and have a low failure rate because they have no moving parts and use the vacuum to extinguish the arc when the contacts separate. They are widely used in power systems and industrial applications because they can perform thousands of operations without failure.

2. Long life

Vacuum circuit breakers have a longer lifespan than other types of breakers making them a more cost-effective option in the long run. This is due to the fact that vacuum circuit breakers do not require any medium to quench the arc resulting in less wear and tear on the breaker components over time.

3. Arc extinction

Vacuum circuit breakers extinguish the arc with a vacuum ensuring that no toxic gases or harmful substances are released into the atmosphere. Since these gases are not present, vacuum circuit breakers are an environmentally friendly and safe choice for electrical power systems.

4. High interruption capacity

Vacuum circuit breakers have a high interruption capacity which makes them ideal for use in high-voltage systems. They are designed to operate in medium to high-voltage systems and can interrupt the current flow in the event of a fault or overload. Vacuum circuit breakers use a vacuum to quench the arc that occurs when the contacts open which allows them to interrupt large currents without damaging the contacts.

5. High resistance to thermal and electrical stress

Vacuum circuit breakers are built to withstand high thermal and electrical stresses making them ideal for use in extreme conditions.

6. Low maintenance

Vacuum circuit breakers require low maintenance which reduces operating costs and improves overall efficiency. This is because vacuum breakers have fewer moving parts and are not exposed to contaminants that can degrade the insulation and interrupting capabilities of the breaker.

7. Improved safety

Vacuum circuit breakers are designed to be safer for the user and the environment making them ideal for use in high-risk applications.

In a high-voltage electrical power distribution system, a vacuum circuit breaker can be used to interrupt the current flow in the event of a fault or overload. Unlike other types of circuit breakers such as oil circuit breakers, vacuum circuit breakers do not use any environmentally harmful substances like oil or gas to extinguish the arc that forms when the circuit is interrupted. This makes them much safer for the environment and reduces the risk of fire or explosion.

8. Easy to install

Vacuum circuit breakers are easy to install making them a cost-effective option for new installations and upgrades.

Let’s say that a factory needs to upgrade its electrical system to accommodate new machinery. They could either install traditional circuit breakers or vacuum circuit breakers. The factory decides to go with vacuum circuit breakers because they are easier and quicker to install which means that the factory can resume operations sooner.

9. No degradation over time

Vacuum circuit breakers do not degrade over time which ensures consistent performance over their lifespan.

Now, since vacuum circuit breakers do not degrade over time, you can rest assured that they will continue to perform consistently throughout their lifespan. This means that it will be able to interrupt the flow of electricity reliably without any reduction in its performance even after many years of use.

10. High-speed operation

Vacuum circuit breakers have a high-speed operation making them ideal for use in fast-paced electrical systems. They can interrupt high current and high voltage circuits quickly which is essential in many industrial applications. Vacuum circuit breakers are commonly used in power generation facilities, transmission networks and distribution systems. They are also used in high-voltage direct current (HVDC) systems where fast switching is necessary for efficient power transmission.

11. No fire hazards

Vacuum circuit breakers do not pose any fire hazards as they do not contain any flammable components. However, there may still be some external factors or conditions that could cause a fire in the surrounding area of the circuit breaker such as electrical overload or short circuits. Therefore, it is always recommended to follow safety guidelines and proper maintenance procedures for any electrical equipment to prevent accidents or potential risks.

12. Ease of maintenance

Vacuum circuit breakers are easy to maintain which reduces downtime and increases system efficiency.

Because vacuum circuit breakers are easy to maintain, the maintenance team can quickly inspect and repair them if needed. This means that if a problem does arise, it can be fixed in a timely manner reducing downtime for the factory.

13. Cost-effective

Vacuum circuit breakers are cost-effective in the long run as they require low maintenance, have a longer lifespan and improve overall system efficiency.

For example, let’s say a company is planning to build a power substation and they are comparing different types of circuit breakers to use in their system. The vacuum circuit breaker is cost-effective in the long run as it requires low maintenance, has a longer lifespan and can improve overall system efficiency. Thus, the company decides to use the vacuum circuit breaker in their power substation as it will provide them with more benefits over time.
