Communications industry solution

Communications industry solution:

Elitech Power Generator guarantees the communication industry.

Communication industry generators are mainly used in power station, province power station is about 800kw, the municipal is about 300-400kw,usually their running time is very short, which is chosen by standby power. County is below 120kw, the generators are chosen by prime power. In addition to the functions of auto start, auto transfer, auto running, auto commissioning and auto stop, the generators also will equip with failure alarming and auto protect device.

Products demands and challenge

The generators which are used in communication industry are similar with the generators in hospital. However, the communication industry generators have higher requirements for environment. Thus, the generators are very strict with stable performance, AMF and ATS functions, instant start time, low noise, low emission, immunity, safety and so on.

1. Automation

Automatically start and load
The generators will automatically start after receiving self-control or remote control command, the success rate is more than 99%. A start cycle includes three starts, the time interval between two starts is 10-15s.
Once the generators start successfully, they will automatically load when the oil pressure reaches specified value. Usually the load time is 10s.
The generators will not start again if fails for three times, they will send start failure alarming signal and will transfer the signal to standby generators.
Automatically unload stop
The generators will automatically unload after receiving self-control or remote control. There are two stopping way including normal stop and emergency stop. Normal stop is to cut off main circuit (cut off MCCB or transfer ATS to mains); Emergency stop is to cut off main circuit, fuel pipe.
Auto protecting generators are with protections of low oil pressure, high voltage, over speed, overload, short circuit and phase shortage. The water cooling generators have high temperature protection; air cooling generators have high cylinder protection.

2. Remote monitor function
The generators can meet the technical demands of remote monitor, they have remote test, remote communications and remote control functions, and they will instantly monitor the running parameters and status from remote areas. The generators will automatically alarm when they meet abnormal situation or serious failures, and then realize remote control. They will also provide standard communications protocol.

3.Thread and parallel functions
Thread standby functions: it can equip with ATS and realize the automatically transfer function between mains and generators, and also double standby transfer function between two diesel generators.
Parallel function: two or more generators, with same model and specification, meeting the demands of 20-100% rated power can paralleling run stability under rated power factor. In order to increase the reasonable distribution accuracy and running stability between active power and reactive power, it requires that the generators speed governor must be with stable speed adjustable rate from 2-5%. Inside of the control panel, the voltage adjustment device can make the stable voltage adjustable rate within 5%.

4. Working conditions
The generators can run below 3000m of the altitude.;
Environment temperature is from -15 C°to 40 C°, other environmental generators are optional.

5. Stable performance, strong reliability
The generators are with external fuel adding system, and lock function; Usually the generators will equip with bulk fuel tank, which can run for 12-24hrs.

6、Convenient fuel adding facilities and protections.
The generators are with external fuel adding system, and lock function;
Usually the generators will equip with bulk fuel tank, which can run for 12-24hrs.

Solutions:

The generators, with advance performance, adopts low noise design, equip SmartGen/Harsen/DeepSea control panel which is with AMF functions. Through connection with ATS, it makes sure the alternative power supply instantly when the mains(city power) is off.

Advantages:

Provide full set products and project, reducing the users’ demands for products technology, which will be easier for generator running and maintenance.
The control system is with AMF function, which can auto start, with auto stop and alarm functions under various monitors.
ATS is optional: it can be inside the generators for small power.
Super silent: The noise level of power below 30kva is below 65dBA.
Stable performance, MTBF is not less than 2000hrs;
Compact dimension, some devices are optional for cold or high temperature areas.
Special design for your special requirements.
