3BHB004661R0101/KUC711AE101 Module

ABB 3BHB004661R0101 KUC711AE101 is a rotary machine excitation controller produced by ABB. It adopts a modular design and can be used for various types of rotating machines, including generators, motors, transformers, etc.

The main functions of KUC711AE101 are as follows:
Provide constant, adjustable or pre programmed excitation voltage
Provide excitation voltage overvoltage, undervoltage, and undervoltage
Provide excitation current overcurrent and undercurrent protection
Provide excitation system fault diagnosis

KUC711AE101 consists of the following main components:
Controller: responsible for controlling parameters such as excitation voltage and current
Isolation Transformer: Isolation Controller and Excitation System
Power module: provides excitation voltage
The controller receives control signals from the upper computer or other devices and calculates the required excitation voltage based on these signals. Then, the controller transmits the calculation results to the isolation transformer. The isolation transformer isolates the control signal output by the controller and provides it to the power module. The power module converts the control signal into excitation voltage and outputs it to the excitation system.

The technical parameters of KUC711AE101 are as follows:
Excitation voltage: 0-1500 V
Excitation current: 0-100 A
Excitation voltage regulation range: 0-100%
Excitation current regulation range: 0-100%
Excitation voltage overvoltage protection: 1.15 times the rated excitation voltage
Excitation voltage undervoltage protection: 0.85 times the rated excitation voltage
Excitation current overcurrent protection: 1.2 times the rated excitation current
Under current protection for excitation current: 0.8 times the rated excitation current
KUC711AE101 can be used for various types of rotary machines, including:
Generators: hydro generators, thermal generators, wind turbines, etc
Electric motors: synchronous motors, asynchronous motors, etc
Transformers: Oil immersed transformers, dry-type transformers, etc
KUC711AE101 has the following advantages:
Modular design, flexible configuration according to needs
By adopting advanced control technology, precise excitation control can be achieved
Equipped with comprehensive protection functions, it can ensure the safe operation of the excitation system
