Special Online Electricity UPS System Multiple Monitoring Zero Switch
CND310 system consists of electrical UPS, DBW bypass stablalized cabinet, and feeder cabinet of PDU series. CND310 is product that CONSNANT TECHNOLOGY CO., LTD, according to the requirement of China Power, designs exclusively for power plant, transformer substation, and distribution substation. It possesses on-line double conversion and zero switch function. It can be mainly applied for power system telemechanics, PTU, power line communication, power system monitoring and etc.. After being isolated and filtered by regulator, Single-phase 220V or three-phase 380V can provide stable power for load through inverter when the AC is normal. If the failure of AC power grid supply or a power cut occurs, direct current panel, the backup of power system, can invert to supply electricity through non-return diode. If the direct current panel is under voltage or cut off, static switch can shift to bypass stabilized cabinet to supply electricity. When the AC power becomes normal, the static switch automatically shift to AC power grid to supply electricity reversely. If the inverter is overloaded or the fault occurs to it, the static switch shift to bypass stabilized cabinet to supply electricity and indicates a warning signal at the same time.
