Trace dynamic power is the corebasis of the bank of electronic
technologyequipment. Banks have a large number of advanced computer
technologyequipment, but only by the electronic computer is stable,
reliable operation to exert its efficiency, the reliable operation
must rely on the strict environmental conditions of the electronic
computer room, including the room temperature, humidity,
cleanliness, noise, vibration, electrostatic, the electromagnetic
interference conditioncontrol precision, etc., while continuous
uninterrupted power supply is the corefoundation of computerdata
Like hospitals use diesel generating sets, but the bank has higher
requirements in environment such as anti-jamming,so the stability
of the performance of the diesel generator set, AMFATS function,
instant startup time, low noise, low emissions, anti-interference,
security,so on various aspects have stringent requirements.
1, work conditions,
Units can work reliably under the following conditions, the output
power,can work continuously for 24 hours in the rated power output
(including can overload 10% work for 1 hour every 12 hours).
Height is not more than 1000 meters above sea level;
Ambient temperature limit of 15C, upper limit is 40C, can choose
other environmental units.
2, low noiselow emissions
Low noise, with enough quiet environment to ensure that the data
center system securitythe bank staff to work;
Low emissions, in order to ensure the purity of the room, to ensure
that the computer systemdata security.
3, the mainthe necessary protection
Unit to start the battery voltage automatic detectionalarm, unit
automatic delay shutdown in the following situations: low, high
water temperature, water level is too low, loadthe startup fails,a
In the following situations emergency stop: high speed, short
circuit, lack of phase, voltage, pressure loss, low frequency;
In the following situations automatically send out soundlight alarm
signal, low oil pressure, high water temperature, water level is
too low, overload, start-up failure, speeding, short circuit,
phase, frequency of high voltage,low pressure loss, start the
battery voltage is too low, start the battery voltage is too high,
low oil levelsets the alarm system of relay contacts;
During starting-up mode choice for automatic start mode. Unit must
have AMF (automatic) mains failure function, equipped with ATS,
realizes automatic starting. < when mains power, starting time
delay after 5 seconds (adjustable), can automatically start unit (a
total of three continuous automatic start function), all negative
switching time mains/unit as < 10 seconds, fully meet the input
load time needed for less than 12 seconds, restore after the mains,
unit to maintain a scale of 0-300 seconds (adjustable), automatic
stop running after cooling.
Equipped with UPS power supply system.
4, adopts brushless permanent magnet excitation alternator, can
provide higher motor starting to bear ability,the host of the
output voltage waveform distortion of the stator has anti-jamming,
generator can be improved with nonlinear load capacity. A stronger
ability to withstand short-circuit current (up to 3 times rated
current, usually lasts 10 s).
5, stable performancehigh reliability
The average unit failure intervals not less than 2000 hours;
Technical performance, the unit of no-load voltage setting range is
95-105% of the rated voltage;
To phased rectifier unit, switch power supply, UPS power supply,
power supplyother load when the load is less than 50% of unit value
is not going to happen when the low frequency oscillation;
Generator can overload under rated voltage 1.5 times rated current,
after 2 minutes;
Unit with remote sensing, remoteremote control function, can in the
localremote monitoring, acquisition, processing, recordingreporting
relevant data of the equipment.
