Step-down device applied Single-phase 3-wire high efficiency power saving distribution method

摘要

PROBLEM TO BE SOLVED: To address a situation in which it is difficult to appropriately use a voltage level and a current balance rate of an electric lamp power distribution main line without variations and in which a single-phase 100 V electric device with a lower power factor, in particular, is constantly adversely affected and convenience of stable supply is insufficient and to provide a technique for removing reasons for the lack of the convenience and increasing the efficiency of power reception.SOLUTION: There is provided a method for step-down device applying single-phase 3-line-type high-efficiency power-saving power distribution that collects, reduces, and saves the number of 100-V dividing circuits appropriate for a step-down device/transmission capacity VA, removes voltage drop and imbalance rates between voltage phases and currents causing electric harmful effects on a load connection point, a dividing circuit, a main switch, a power company system, and increases the efficiency of power reception.SELECTED DRAWING: Figure 7
