Overview

With the development of data center technology and the requirement of reducing operation cost and energy-saving and emission-reduction,HVDC has obvious advantages over traditional UPS in terms of energy saving, investment cost reducing, high reliability and convenient operation and maintenance. Meanwhile, with more and more widely application in large Internet data centers and other fields, HVDC power supply will gradually become the trend of power supply for data center in the future.

In order to keep the safe, stable and reliable operation of HVDC system, the precision DC power distribution unit is adopted to realize high accuracy electric monitoring of each circuit in DC array cabinet so as to achieve fine energy management; the insulation monitoring module is adopted to monitor the ground insulation performance for the whole DC system so as to realize monitoring, judging and prevention of grounding fault. DC precision distribution unit can transmit data to dynamic environment monitoring system through digital communication to provide guarantee for post operation management.

Composition of HVDC precision distribution unit

Composition of BCM201 precision power distribution unit

A precision array cabinet provides safe and reliable power supply to server appliance of data center energy terminal, and precision power distribution units provide high-precision measurement data for data center energy monitoring system. As a result, power quality data are reflected in real-time through human-computer interface. Moreover, such data are uploaded to background dynamic environment monitoring system through digital communication, realizing real-time monitoring to the whole power distribution system. With the continuous development of IT technology, the reliability and meticulous management requirements of data centers have been gradually improved. Large scale and high-density power consumption has become the trend of data center.
