数据中心用发电机组 Data center generator
Data center generator
With fast start-up capability, low emissions and noise control, a comprehensive monitoring system, and extremely high reliability, data center generators are the cornerstone of ensuring 24/7 uninterrupted operation in the digital world.
Chinese manufacturer of data center generator sets
The generator set used in data centers is a highly complex and reliable engineering system, rather than a simple single device. The data center power system follows a high redundancy design of "2N" or "N+1".
After a power failure, the data center's generator set can quickly respond, automatically or manually start, and provide power to critical loads such as IT equipment, cooling systems, lighting, and monitoring systems.

Issues of concern to users of data center generator sets
1、 What are the reasons for the lack of response when the data center generator set starts?
Possible reasons:
Battery issues (most common): battery depletion, corroded or loose connectors, battery aging.
Start motor malfunction: damaged electromagnetic switch, motor itself malfunction.
Control circuit failure: blown fuse, relay malfunction, loose wiring.
Handling method:
Immediately check: Measure the battery voltage, clean and tighten the wiring terminals.
Emergency handling: Use a backup external charger to charge the battery or start in parallel.
Professional maintenance: replace faulty batteries, starter motors, or repair control circuits.
2、What are the reasons for voltage fluctuations after the start-up of data center generator sets?
Possible reasons:
Excitation system failure: AVR (Automatic Voltage Regulator) instability or malfunction.
Winding problem: There is a local short circuit or grounding fault in the excitation winding or main winding of the generator.
Loose connection: Loose connection at the output busbar or cable connection, resulting in poor contact.
Handling method:
Check connections: Tighten all electrical connection points.
Check AVR: Observe the working status of AVR and replace it if necessary.
Insulation test: Professional personnel conduct insulation resistance tests on generators to identify winding faults.
3、What are the reasons for the sudden stop of data center generator sets during operation?
Shutdown due to high water temperature:
Possible reasons:
Cooling system issues: insufficient coolant, clogged radiator, broken or loose fan belt, water pump malfunction.
Overloaded: Long term overload operation.
Handling method:
Immediately check: After stopping the engine, check the coolant level and fan belt tension after the engine has cooled down.
Cleaning the radiator: Clean the dust and willow fluff on the radiator fins with compressed air or water.
Check the thermostat and water pump: Ensure that the coolant circulation is normal.
Low oil pressure shutdown:
Possible reasons:
The oil level is too low or the oil quality is unqualified.
Oil pump malfunction or clogged suction filter.
The engine has severe internal wear and excessive clearance.
Handling method:
Check engine oil: Check the oil level and quality, and add or replace engine oil that meets the standards if necessary.
Professional maintenance: If the oil level is normal, it may be a mechanical failure and requires professional disassembly and repair.
