Functional Description
URRHH is a high-speed protection dedicated I/O module developed by GE, which is an important functional expansion component of the Multilin UR series relay protection system. This module is mainly used for high-speed signal acquisition and rapid protection trip output of power transmission and transformation equipment, focusing on high-response protection scenarios such as substation line protection, transformer protection and power distribution fault rapid isolation. The URRHH module features ultra-fast signal response speed and high-precision signal identification capability, which can capture transient fault signals of the power system in real time and quickly execute protection command output. It adopts a professional anti-interference and redundant circuit design, which can maintain stable and reliable working state in complex electromagnetic interference environments of power systems, effectively shorten the fault response time of relay protection equipment, reduce the scope of power system fault impact, and ensure the safe, stable and efficient operation of power grid and industrial power distribution systems.
Features
The GE URRHH High-Speed Protection I/O Module is specially optimized for power system high-speed protection business, serving as the core signal input and output unit for rapid fault response of UR series protection relays. The module integrates high-speed digital signal acquisition channels and fast relay output contacts, which can realize real-time collection of power system switch state, fault alarm signals and instantaneous execution of protection trip, closing and linkage control commands. Compared with conventional I/O modules, it has shorter signal delay and higher action accuracy, which can fully meet the strict response time requirements of primary protection and quick protection of power equipment.
In terms of performance design, the URRHH module adopts industrial-grade high-speed chip processing architecture and hardware rapid response circuit, which greatly reduces signal acquisition and command output delay, ensuring microsecond-level rapid response to power system transient faults. The whole machine is designed with strong electromagnetic compatibility, with built-in lightning protection, surge suppression and signal isolation circuits, which can effectively resist strong electromagnetic interference, voltage surge and current impact in substation and power plant environments, avoiding signal distortion and module misoperation, and improving the stability and anti-interference ability of the protection system.
The module is fully compatible with GE EnerVista UR configuration software, supporting one-click parameter setting, protection logic matching, channel status monitoring and operation data recording. Users can flexibly configure signal input modes and protection output logic according to on-site power system working conditions, which is convenient for equipment debugging, operation management and later maintenance. It has excellent system compatibility, can be perfectly matched with all UR series relay hosts, supports plug-and-play installation and hot-swap maintenance, does not need system shutdown during module replacement and maintenance, effectively improves the operation continuity of power protection equipment.
The URRHH module has perfect safety redundancy and fault self-diagnosis functions. It can automatically detect channel abnormality, module operation failure and signal loss in real time, and feed back fault information to the host system in time to trigger protection locking and alarm prompts, effectively preventing equipment misoperation and refusal operation. Its compact and standardized structural design is suitable for standard cabinet installation, with strong environmental adaptability, which can operate stably for a long time in high temperature, low temperature and humid industrial power scenarios, meeting the long-term and reliable operation requirements of power automation protection system.
