Study Of Communication-Capable And Intelligeng DC Distributor Shelf

The DC distributor shelf play a important role in transformer substation, power plant, big and middle plants etc. It supply mainly to the controled, protected and communicate equipment, automechanism, manipulaor and adjusted machine.The same time it may as accident lighting power supply, so its performance and reliability affect directly the running safely of whole power supplying system. With the electricity net automatization and the power supply equipment nobody-guard, the society put forward highly appeal about safety. realiability and stabilization. So the study of communication and intelligence DC power supply become an important task in electricity net rebuilded , now.In this paper , we analyse the realization problem of the DC power supply on base of the latest research native and abroad. From pratice , we explain detailedly the realization. necessity and importance, and introduce emphasisely the software and hardware of the DC distributor shelf.In the task, we utilize power electronics technology , controled technology and micro-electronics technology, adopt single-chip controlling a new intelligent thyristor power module (ITPM) and realize the DC distributor shelf , It have four founctions (strong charge, even charge , float charge , automatic charge,) three long-distance control, alarm and intelligent display etc.
