Circuit Breakers

A circuit breaker is an electrical device designed to protect an electrical circuit from damage caused by overloading, short-circuiting, or ground-faulting. Circuit breakers are widely used in domestic and industrial electrical systems. The IEG11-21633-3 circuit breaker is one such device.

IEG11-21633-3 Application Field

The IEG11-21633-3 circuit breaker is a medium-voltage (MV) circuit breaker used in power systems in different industries, including electrical power distribution services, power station circuits, and renewable energy systems. It is typically used with MVEV-3 switchgear and has the capability to provide protection for circuits used for electrical power transmission and distribution. It can provide protection for systems with rated voltages ranging from 6 kV to 46 kV.

The IEG11-21633-3 circuit breaker is designed to provide a fast response time and reduce the potential of transmission line operations. It is capable of detecting a wide range of fault conditions, including over-voltage, over-current, and ground-fault conditions. Additionally, it is able to identify abnormal conditions and react appropriately by tripping the circuit breaker, thereby preventing further damage.

IEG11-21633-3 Working Principle

The IEG11-21633-3 is a two-pole, three-phase circuit breaker that is based on the jet-assist pressure system. It is built with a bellows-style dielectric gas system, which provides a fast response time when responding to fault conditions. The unit includes a transducer, a pressure-sensing device, and a gas blast system. When a fault occurs, the transducer detects the fault condition and sends a signal to the pressure sensor. The pressure sensor then triggers the release of stored energy from the bellows-style dielectric gas system, resulting in the rapid ejection of high-pressure gas. This, in turn, causes the circuit breaker to trip, thereby preventing further damage.

The IEG11-21633-3 circuit breaker also features an adjustable current limitation mechanism, which can be set according to the specific requirements of the system. The adjustable current limitation mechanism helps limit the fault current, thereby reducing the amount of damage caused by the fault. Additionally, the unit features a motorized switch mechanism, which allows for the remote operation of the circuit breaker. This makes it possible to control the circuit breakers remotely, which eliminates the need to manually operate them.

Conclusion

The IEG11-21633-3 is a medium-voltage circuit breaker that is designed to provide protection for electrical power transmission and distribution systems. It is based on the jet-assist pressure system and includes a transducer, a pressure-sensing device, and a gas blast system. The adjustable current limitation mechanism helps to limit the fault current, and the motorized switch mechanism allows for remote operation of the circuit breaker. Therefore, this circuit breaker is capable of providing fast and efficient protection from electrical faults.
