The selection of Air switch and connecting wires
The wires for different capactity of UPS should be with different grade,
unsuitable wires or air switch will easily bring dangers. The principle of selection are:
3-5A/mm
2
for middle and small size UPS, 2.5-3A/mm
2
for big power UPS. Meantime,
we should consider to control the max voltage drop no more tha n 3V.
There have input neutral wire for bypass and output neutral wire for UPS power
in the UPS midline system. For three phases in and single phase out UPS, the
cross-sectional area of input null line should be 1.5-1.7 times of phase line.
There have groundings for safe protection and lightning protection in the UPS
systerm, their cross-sectional area should be 0.5-1.0 time of phase line and no smaller
than 6mm
