Product descriptions

The BGZDW intelligent fully digital program-controlled DC screen is designed in accordance with the technical specifications of the Ministry of Electric Power's "DL/T459-2000" and the "JB/T5777-2000" General Technical Conditions and Safety Requirements for DC Power Supply Equipment in Power Systems. A new generation of unmanned power supply system developed based on years of research and manufacturing experience in DC power supply systems. The module adopts the most advanced edge resonant soft switching technology, which can be plugged and unplugged with power. The modules are designed with isolation between each other, and the modules have a built-in CPU. All benchmark calibration and control of the modules are completed using 12 bit D/, avoiding parameter drift caused by the inherent temperature and mechanical coefficients of the potentiometer. The built-in E2ROM in the external module ensures that the operating parameters of the module are never lost. The monitoring system adopts a modular structure design, which is divided into: central main monitoring unit, DC monitoring unit, switch monitoring unit. It can also be equipped with battery inspection unit and insulation detection unit as needed. Each unit is connected to the central main monitoring through RS485 port. This modularity makes maintenance work very simple and fast. The monitoring system also has "four remote" buttons and standard Rs232 interface, which can meet the requirements of power plant automation and unmanned substations for power system automation.
