Circuit Breakers: Application Field and Working Principle of UPGF6-31869-20

Circuit breakers are important components in electrical distribution and power control systems. They are designed to both protect the electrical system from damage due to short circuits and to provide manual or automatic switching. UPGF6-31869-20 is a type of air-break circuit breaker, which is suitable for use on systems with an AC voltage up to 40kV and a rated current up to 4000A. Its application field and working principle are discussed in this article.

Application Field

UPGF6-31869-20 is an air-break circuit breaker, which is used on electrical systems with voltages up to 40kV and a maximum current rating of 4000A. It is applicable for a wide range of applications, including industrial, commercial, marine and military installations. This means that the circuit breaker can be used for power distribution in large factories, large buildings, ships, and other places where a high-voltage, high-current power system exists. It is also designed to offer protection for the power system from short circuits and other dangerous events which could cause severe damage to the system.

Working Principle

The UPGF6-31869-20 is a three-phase type of air-break circuit breaker, meaning that it is designed to function effectively in three-phase AC power systems. Its operation is based on the idea of using air pressure to break the electrical connection when a dangerous situation is detected and an “open” condition is required. When the circuit breaker is triggered and opened, air will be used to extinguish and break the electric arc between the contacts which cause the circuit to be broken. This ensures that the current in the system is interrupted and any further damage is prevented.The UPGF6-31869-20 acts like a normal circuit breaker in case of a normal overcurrent situation. It will either directly trip the breaker or activate protective relays in order to protect the system from overcurrent and overvoltage. It also includes a fast- and a slow-acting trip element, which enables it to detect and respond to different levels of overcurrents in a highly efficient manner. The fast-acting element will respond quickly to short-circuit current, while the slow-acting element will only trip the breaker in case of extended overcurrents.

Conclusion

The UPGF6-31869-20 is a type of air-break circuit breaker, which is suitable for use on systems with an AC voltage up to 40kV and a rated current up to 4000A. It is designed to offer protection for the power system from short circuits and other dangerous events which could cause severe damage to the system, and is applicable for a wide range of applications, including industrial, commercial, marine and military installations. Its working principle is based on using air pressure to break the electrical connection when a dangerous situation is detected, thus ensuring that the current in the system is interrupted.
