Product Description
Customized Electricity Special UPS with 110VDC 20kVA


Customized Electricity Special UPS with 110VDC 20kVA

The CND310 series Electricity Special UPS system consists of system cabinet, DBW bypass stabilized cabinet, and PDU feeder cabinet. CONSNANT designs exclusively for power plant, transformer substation, and distribution substation according to the development requirement of China Power. It possesses on-line double conversion and zero transfer function.
It can be mainly applied for
power system telemechanics, PTU, power line carrier, power system monitoring and so on. 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, the backup of DC power system can invert to supply electricity through the reverse diode. If the DC Power System is under voltage or cut off, the static switch will turn to bypass automatically. When the AC power is recover, the static switch will turn to AC power automatically. If the inverter is overloaded or fault, the system will turn to bypass and indicates a warning signal at the same time.


Key Features:
  • Adopt full digital control technology
  • Intelligent detection and monitoring function
  • Digitally control the static switch with zero switch
  • Full isolation between input and output
  • Super low output zero earth voltage
  • DC UPS isolated with utility power completely
  • Cubical design with power standard (customization)
  • Multifunctional protection for overvoltage, under voltage, over current, short circuit and over temperature and so on.
  •  Large-screen LCD monitor with Chinese and English operation interface
  • Ultralong 256 event record, user-friendly analysis and management to the situation of the power supply (touch screen optional)
  • Static bypass has a strong anti-overload capability
 

Control system
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.
 
Rectifier
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.
 
Inverter
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.

Large Capacity of Overload of the UPS Inverter
110% load --60'
125% load --10'
150% load --1'
200% single phase load --30"
Good Capacity of Resistance to Output Short Circuit Current Limiting and Period Load Impact
Advantages:
290% rated current -- 5": Even though a output short circuit or an overload occurs because of user's improper operation, the output current of UPS can still be limited to a controllable extent instead of exceedingly increasing, consequently laying a good foundation for a long-term and reliable operation of UPS.

 
 
Static switch:
Not sync automatically switch:
  • When the bypass of the UPS lose sync with the inverter, system can automatically implement not sync switch, for example, when the utility power surge pulse width <5ms, the system can ensure no power cutoff.
  • When the bypass exceed the limitation, UPS will detect the bypass every 20ms, when the phase angle difference of bypass and the inverter turn to normal range, not synchronized bypass shifting can be realized.

Intelligent monitoring
Working status and data of UPS are transmitted to DCS system in real-time via RS232/RS485, passive contact and power transmitter, which finally realize Intelligent monitoring.
 
Unique option:
  • SNMP card
  • Dry contact card
  • Signal transmitter
  • Bypass isolation and voltage regulation
  • Increase feeder circuit (standard for 8 loops)
  • 12 pulse rectifier
  • The appearance of special models(standard dimension:800×600×2260mm)
