Description
ABB UNS3020 is a rotor grounding protection device, the following information about its parameters, specifications, features and functions:
Parameters and specifications:
Model: UNS3020.
Brand: ABB.
Type: rotor grounding protection device.
Protection level: Level 2 protection (level 1 alarm, level 2 jump).
Scope of application: Suitable for rotor grounding protection of 1000MW generator excitation system.
Features:
The UNS3020 uses the Wheatstone bridge principle for measurement and has the characteristics of high precision and fast response.
The device has a two-level protection function, and different protection policies can be selected according to different fault conditions.
The UNS3020 has adjustable setting and delay functions, which can be flexibly configured according to actual needs.
The device also has a self-diagnosis function, which can monitor the running state of the equipment in real time to ensure the reliability of the system.
Functions:
The UNS3020 is mainly used to protect the rotor windings of the generator from ground faults. When a ground fault occurs in the rotor winding of the generator, the device can quickly respond and trigger the corresponding protective action to prevent the fault from expanding and causing damage to the generator.
Through the protection of UNS3020, the operation reliability and stability of the generator can be improved to ensure the normal operation of the power system
