Product needs and challenges

Similar to the use of diesel generator sets in hospitals, but banks have higher requirements in terms of anti-jamming environment, so the performance stability of diesel generator sets, AMF and ATS functions, instant start-up time, low noise, low exhaust emissions, anti-interference Sexuality, safety and other aspects have stringent requirements.

1, working conditions

The unit can work reliably under the following conditions, output power, and can work continuously for 24 hours in rated power output mode (including 10% overload for 1 hour every 12 hours);

The altitude does not exceed 1000 meters;

The lower ambient temperature is -15C° and the upper limit is 40C°. Other environmental units can be used.

2. Low noise and low emissions

Ultra-low noise, ensuring the security of the data center system and the peace of mind of the bank staff with sufficient quiet environment;

Low exhaust emissions to ensure the cleanliness of the machine room and ensure computer system and data security.

3. Main and necessary protective devices

The unit can automatically detect and alarm the starting battery voltage. The unit will automatically delay the shutdown under the following conditions: too low, too high water temperature, low water level, overload, failure to start, and send corresponding signals;

Emergency stop under the following conditions: overspeed, short circuit, phase loss, over voltage, voltage loss, low frequency;

Automatically emit audible and visual alarm signals under the following conditions: low oil pressure, high water temperature, low water level, overload, startup failure, overspeed, short circuit, phase loss, over voltage, voltage loss, low frequency, starting battery voltage Too low, start battery voltage is too high, low oil level and the unit's alarm system has relay contacts;

The unit start mode is selected as the automatic start mode. The unit must have AMF (automatic mains failure) function, equipped with ATS, to achieve fully automatic start. When the mains power fails, the starting time delay is less than 5 seconds (adjustable), the unit can be started automatically (there are three consecutive automatic starting functions), and the mains/units have a full negative switching time of <10 seconds, which fully meets the time required for the input load. Less than 12 seconds, after the mains recovery, the unit maintains 0-300 seconds after running cooling (adjustable) automatic shutdown;

Equipped with UPS power system.

4. The brushless permanent magnet exciter alternator can provide high motor starting bearing capacity, and has anti-interference effect on the waveform distortion of the main stator output voltage generated by the non-linear load, which can improve the non-linear load of the generator. ability. Stronger ability to withstand short-circuit current (usually up to 3 times rated current for 10S).

5, stable performance, strong reliability

The average failure interval of the unit is not less than 2000 hours;

In terms of technical performance, the no-load voltage setting range of the unit is 95-105% of rated voltage;

When the unit supplies power to the phase-controlled rectifier, switching power supply, UPS power supply or other load, low-frequency oscillation will not occur when the starting load is less than 50% of the rated value of the unit;

The generator can be overloaded with 1.5 times of rated current at rated voltage for 2 minutes;

The unit has telemetry, remote signaling and remote control functions to monitor, collect, process, record and report data about the device locally and remotely.

  solution

The generator set with excellent performance and low noise design is equipped with the PLC-5220 control system with AMF function. By connecting with ATS, it ensures that once the main power supply is cut off, the alternative power supply system must be able to supply power immediately. Stable, low noise, engine power that meets European and American emission standards, and AMF functions and ATS equipment make it meet the special requirements of banks. It is equipped with RS232 or RS485/422 communication interface to realize connection with computer, remote monitoring, remote control, remote communication and telemetry, and it is fully automatic and unattended.
