Distributed dc power series


Product introduction


Distributed dc power supply is a new kind of dc power supply equipment, mainly used in small switching station, and end users, as the secondary control circuit intelligent terminals (such as microcomputer protection and indicator lamp, simulation, etc.) work to provide reliable uninterrupted power supply, avoid communication lose protection, loss of electricity led to the microcomputer protection solution due to factors such as operating over voltage and harmonic make UPS failure resulting in microcomputer protection problem.At the same time, it can also provide dc operating power for primary switching equipment (spring mechanism vacuum circuit breaker, permanent magnet mechanism vacuum circuit breaker, electric load switch, etc.) meeting the power requirements of the device.




Product features


◎ distributed dc power supply is small in size, convenient in installation and wiring, suitable for scattered installation in various types of switchgear.


◎ it is more reliable than ordinary dc screen system, more economical (more obvious for small user terminals), and saves space, reduces line loss and installation work, and easy to maintain, providing a new option for power supply reliability of power system.


◎ the distributed dc power supply adopts high-frequency power supply technology, and the battery adopts automatic charging management module for maintenance, which greatly extends the service life of the battery and makes the operation of the device more safe and reliable.


◎ the device has communication, alarm function, can easily realize unmanned remote automatic management.




Operating environmental conditions


Ambient temperature of the working group: -10℃ ~ +45℃;


Maximum monthly average relative humidity: ≤90%;


Maximum daily average relative humidity: ≤95%;


Altitude: no more than 2000m;


Working environment conditions: no conductive particles and dust, no corrosive metal and insulating chemicals, the site should be equipped with protection against rain, snow, wind and sand, no water vapor or serious mold around.




Typical application scenarios


Small switching stations, ring network cabinets, box-type substations and user terminals provide dc power for secondary control lines, primary switching equipment (spring mechanism vacuum circuit breakers, electric load switches, etc.), communication optical terminals, etc.
