Power Plant Electricity UPS System Digital Control Output PF 0.8
10 - 100KVA
Petroleum, chemical industry, gas and power station and so on.
It adopts microprocessor bus control technology, three core processor controlling rectification, inversion and parallel connection respectively, to ensure the real-time control of the rectifier, inverter and static switch and the coordination of every power part, characterized by increased control of aging, higher reliability, enhance of the efficiency of the whole UPS system and the output technical parameters are better than that of the device with same capacity.
6 pulse or 12 pulse fully controlled bridge (6 or 12 SCR) compose rectifier. Its function is to input AC 3880V to DC220V or so by rectification. “slope” start (soft start) is the control feature, which means output voltage of the rectifier increase from 0V to 220V within 10 second and has no impact on the power grid.
SPWM(sinusoidal pulse width modulation) , formed by 6 IBGT high power tubes, is composed of full-bridge-control. Its function is to transform DC voltage into sinusoidal AC voltage, boosting by the special (△/Y) zero phase shift zigzag type isolation transformer and become AC220V as load required. In addition, the transformer can eliminate like triple harmonics current that are reflected by non linear load from computer. Control features is the adoption of the “slow-down gate voltage” protection technology, greatly reducing disturbance of shutoff of the inverter (inverter and static switch shift mutually ), enhancing the overload capacity of the whole UPS system, which make the capability of anti-short circuit and anti overload of UPS far superior to the ordinary UPS, especially the anti shot circuit is unmatched by similar devices.
