ABB REF610C11HCHN relay protector is a device used for power system protection, which can detect and isolate faults, ensuring the safe and stable operation of the power system. The following is detailed information about the handling method, fault handling, and characteristics of the relay protector:

Processing method

Current protection: The relay protector detects the magnitude and direction of the current to achieve current quick break protection, overcurrent protection, etc., to prevent equipment damage caused by excessive current or faults.

Voltage protection: Relay protectors detect the magnitude and variation of voltage to achieve overvoltage protection, undervoltage protection, etc., to ensure voltage stability in the power system.

Directional protection: The relay protector can detect the direction of faults, achieve fault isolation in both positive and negative directions, and prevent the expansion of faults.

Differential protection: By comparing the current magnitude and phase on both sides of the line, differential protection of the line is achieved to prevent unbalanced current caused by internal faults.

Distance protection: Based on the principle of impedance relay, it realizes distance protection function and automatically cuts off faults according to the distance to the fault point.

Fault handling

Automatic fault isolation: When a fault is detected, the relay protector can automatically isolate the fault area, prevent the fault from expanding, and ensure the normal operation of other areas.

Alarm and Reminder: When a fault occurs, the relay protector can emit alarm signals through sound, light, and other means to prompt operation and maintenance personnel to handle it in a timely manner.

Recording and tracing: Relay protectors usually have fault recording function, which can record information such as the time and type of fault occurrence, facilitating fault tracing and analysis.

Self diagnostic function: The relay protector has self diagnostic function, which can detect its own status and performance during operation, and timely discover potential fault hazards.

Redundant design: To ensure that the protection function can still be maintained in the event of a main equipment failure, relay protectors are usually designed with redundancy or equipped with backup power supply.

characteristic

High reliability: Adopting high-quality hardware and software design to ensure stable operation of relay protectors in harsh power system environments.

Quick response: Relay protectors have fast detection and response capabilities, which can detect and isolate faults in a short period of time.

Flexible configuration: supports multiple configuration modes and parameter settings, and can be customized according to actual needs.

Easy to maintain and debug: Provides a user-friendly operating interface and debugging tools, making it convenient for users to maintain, debug, and use the device.

High integration: It integrates multiple protection functions into one, reducing the configuration requirements of external components.

Strong compatibility: Supports multiple communication protocols and interfaces, facilitating integration and linkage control with other devices and systems.
