Detailed Product Description: | Nanjing Jintai terminals 380V AC power supply system, due to the needs of the line protection, usually the center point of the three-phase four-wire by grounding device directly grounded. This typical architecture of the data room distribution system shown in Figure 1, the system is typically configured in one or several 10KV/380V △ / Yo transformer, Yo the center point of the side directly grounded through the grounding network, point G in Figure 1, . Load from the transformer to the various IT management considerations for safe operation and maintenance, usually this distance in the line is divided into three distribution bus that UPS input distribution bus or mains input bus L1 (including diesel generator After switching input) UPS output distribution bus L2 floors distribution bus L3 floor distribution splitter and then to the column head cabinet (also floors distribution and column headers cabinet into one), and then single-phase access Rack PDU IT load power supply. In this way, from the secondary side of the transformer ground point G between the input point N to the zero line of the IT load, long transmission distance, when load into operation, there must be a large number of zero line current flow back from the N-point level bus, the bus bar at the zero-emission superimposed superimposed not been offset part will flow back to the G-spot. To form a voltage drop due to the presence of the zero line impedance, between all levels busbar zero row. So that G is the reference point, the various points of the zero line to form a voltage drop on the ground, this is the so-called "zero voltage". Zero voltage for other voltage no special place, just zero line voltage drop. |
