“High voltage DC power supply” to promote joint problem facing
Yancheng branch of China Telecom with the actual needs, in Yancheng, Jiangsu Telecom launched a large-scale high-voltage direct current (HVDC) power technology, trial work, a comprehensive, large-scale use of alternative communication HVDC UPS power supply, with very good energy other aspects of the effect of making room 40% reduction in power, and in January 2010 won the third prize of scientific and technological progress of China Telecom Group, and its depth and breadth of the trial is the first time at home and abroad.
HVDC success of the pilot phase, causing the industry’s communication power supply manufacturers eager attention. Eaton Power (Shanghai) Co., Ltd. SCIENGE product manager for North Asia, said: “The technology has been in nearly a decade of scientific research abroad, and China Telecom was the first to dare to eat crabs. But the technology can not completely replace the short term AC power supply. “Experts believe that the promotion of the technology still faces two difficulties now.
Difficult one: open up the whole industry chain. Despite the high voltage DC power supply has many advantages, but the current IT equipment and communications equipment room itself or 220V AC power supply according to the original design, so its marketing needs together to complete the whole industry chain. The power of manufacturers, to provide DC power supply technology is facing a very real problem: IT equipment, and other load carriers is difficult to judge after a problem is the load power supply manufacturers or manufacturer’s responsibility.
