Description
1.Product Brief Introduction
The commercial ordering model is XVC724BE101, a Sweden-originated core control sub-board belonging to ABB 3BHE dedicated control board family, specially matched with UNITROL generator excitation system and ACS6000/PCS6000 medium voltage high-power converter control rack, compatible with AC800PEC and System800xA DCS control platform. The whole circuit board is coated with three-proof conformal coating against damp, dust and corrosive gas, functioning as flash memory storage and parameter solidification unit of master control CPU, responsible for storing drive operation parameters, control algorithm programs, fault record data and calibration configuration information of the main control system.
2.Model Definition Explanation
3BHE is fixed general prefix of ABB special PCB for generator excitation and medium voltage high-power transmission equipment.009017 is exclusive internal development serial number defined by ABB R&D department for XVC724BE hardware platform.R0101 represents original factory baseline hardware revision without subsequent circuit upgrading or component replacement, corresponding to formal sales part code XVC724BE101.
3.Technical Specifications
Rated working auxiliary power is DC24V±10%, typical power consumption is 1.8W, peak instantaneous power is 2.6W. Working ambient temperature ranges from -25℃ to +70℃, storage temperature ranges from -40℃ to +85℃, applicable relative humidity 5%~95%RH under non-condensing environment, IP20 protection grade for cabinet plug-in backplane installation, conforming to IEC61000 industrial EMC anti-interference standard. Equipped with industrial grade high-capacity onboard flash storage chip, supporting repeated program reading and writing, adopting passive natural air cooling mode, module net weight is approximately 0.11kg, passed CE and UL industrial safety certification.
4.Interface and Communication Configuration
Rear gold finger backplane connector connects ABB proprietary internal rack bus to realize bidirectional data exchange with upper main control motherboard for program download, parameter readback and fault log upload. No external terminal wiring ports, independent Ethernet, Profibus or fiber communication interfaces are configured; all data interaction fully relies on cabinet internal backplane bus, reserved miniature onboard debugging pin only for factory offline program calibration and firmware upgrade.
5.Core Functions
Permanently store solidified control algorithm, user-set operation parameters, protection threshold values and historical fault codes of excitation cabinet and medium voltage converter main control unit, keep stored data intact after system power-off without external backup power supply. Receive parameter modification and program upgrade commands sent by master CPU via backplane bus to complete online data rewriting and storage. Periodically execute self-check of onboard storage chip during equipment running, feed back abnormal fault signal to main control board once storage read-write error or data damage occurs, trigger system corresponding fault alarm prompt.
6.Application Scenarios
Mainly installed in UNITROL5000 and UNITROL6000 excitation control cabinets of thermal power, hydropower and gas power plant synchronous generator sets to preserve excitation regulation parameter and protection configuration data. Meanwhile equipped inside control rack of ACS6000 and PCS6000 medium voltage converters used for metallurgical rolling mill main drive, cement rotary kiln high-power dragging, open-pit mine heavy belt conveyor and petrochemical large compressor variable frequency control equipment.
7.Operation and Maintenance Instructions
Cut off cabinet DC24V control power before disassembly or routine inspection, keep power cut over 30 minutes to release residual electric charge of onboard capacitance and avoid static breakdown of precision storage chip. Conduct semi-annual maintenance by cleaning dust on PCB surface and gold finger contact with dry soft brush, check backplane insertion tightness and metal pin oxidation condition regularly. When system appears parameter loss or program startup failure during operation, confirm backplane connection first before replacing the whole module; arbitrary disassembly of onboard storage components and unauthorized modification of original circuit layout are strictly forbidden.
