Circuit breakers are at the heart of any electrical system and can protect both the building and the inhabitants from electric shock or power outages. The 1Z13UM is a type of circuit breaker that is often used in high voltage applications. This article will discuss the application field of the 1Z13UM and its working principle.

Application field

The 1Z13UM is an ultra-high voltage vacuum circuit breaker that is mainly used in extra-high voltage AC power circuits. It is capable of breaking and making currents up to 80 kA and operates at 13.2kV, 28kV, 40.5kV, and even up to 245kV. It is designed for use indoors and its compact size makes it ideal for using in small spaces. It is also equipped with advanced fault protection, making it suitable for use in critical applications, such as substations, industrial plants and power plants.

Working Principle

The 1Z13UM works in an arc-cooling and insulating vacuum chamber. When an electrical current passes through the circuit, it carries a magnetic field and an arc is created between the contacts when the current is interrupted. In order for the arc to be extinguished, the 1Z13UM uses a series of processes to reduce the intensity of the arc. The first step is to reduce the arc temperature by cooling it with a vacuum. This is done by compressing the air around the arc and reducing the pressure. This results in the arc temperature being significantly reduced, allowing the arc to be easily extinguished. The second step is to insulate the arc and reduce the conduction of the current, which eventually results in the extinction of the arc. When this process is complete, the 1Z13UM has completed its job.

The 1Z13UM is equipped with advanced test and monitor systems, which enable it to detect changes in the current and arc temperature. This helps the 1Z13UM to reduce the risk of damage during operation and to protect the electrical equipment and personnel operating in the area. It also provides an effective protection from electric shock, as the 1Z13UM is designed to detect any abnormal current flow and shut off the power before any injury can occur.

Conclusion

The 1Z13UM is an ultra-high voltage vacuum circuit breaker that is mainly used in extra-high voltage AC power circuits. It is capable of breaking and making currents up to 80 kA and operates at 13.2kV, 28kV, 40.5kV, and even up to 245kV. It is equipped with advanced fault protection, making it suitable for use in critical applications, such as substations, industrial plants and power plants. It works in an arc-cooling and insulating vacuum chamber and is equipped with advanced test and monitor systems, providing protection from electric shock and reducing the risk of damage during operation.
