GZDW Powersupply cabinet

GZDW intelligent high frequency DC power supply cabinet is in accordance with the Ministry of Electric Power Order technicalconditions'DL/T459-2000°,and'JB/T5777-2000 power system DC power equipment general technical conditions and safetyrequirements,combined with years of development of DC power supply system And manufacturing experience and the developmentof a new generation of unattended power supply system.Module using the most advanced edge resonant soft-switching technology,can be hot plug,between modules and modules using isolation design,the module comes with CPU,the module all benchmarkcalibration and controlall 12-bitD/complete,to avoid the potentiometer inherent Of the temperature coefficient and the mechanicalcoefficient caused by the parameter drift.Another module built-in E2ROM,to ensure that the operating parameters of the modulewill never be lost.The monitoring system adopts the modular structure design,which is divided into central monitoring unit,DCmonitoring unit,and switch quantity monitoringunit.The battery inspection unit and the insulation detection unit can also be selectedaccording to the needs.Each unit is connected with the central main monitoring system But also with the "four remote'interface andstandard RS232 interface,to meet the power plant automation and power system automation unattended substation requirements.
