As the emergency standby power supply after
power failure, diesel generator set is in standby state most of the
time. Once power failure or power failure occurs, the standby diesel generator set
plays a vital role.However, we often find that the performance of
diesel generator set has problems after the power supply failure, which
shows that many users do not pay enough attention to the knowledge of AC
false load for diesel generator set detection and maintenance.
1、 Why do we need AC false load for diesel generator set inspection and maintenance.
(1) Test diesel generator set.
By
detecting the AC false load of diesel generator set for maintenance,
the unbalanced load capacity of diesel generator set can be detected to
ensure the steady-state voltage regulation rate, steady-state frequency
regulation rate, transient voltage regulation frequency, voltage
recovery time, transient frequency regulation rate, frequency recovery
time and continuous operation detection of diesel generator set.
(2) Test UPS.
Output
voltage unbalance, output voltage stabilization accuracy, overload
capacity, dynamic voltage transient range, battery switching time,
backup time, bypass inverter switching time.
2、 Main functions of AC false load for diesel generator set detection and maintenance.
(1) Query function.
Query the diesel generator set, search the abnormal record, query the diesel generator set detection data.
(2) Online communication.
The detector can be connected with upper computer through RS232 / RS485 interface.
3. Intelligent control and data processing function.
Data transfer: after testing, the collected data can be transferred to U disk.
Online monitoring of the electrical parameters of the tested equipment.
Data
processing software function: the data processing software is used with
the detector. The detection parameters can be set to analyze and deal
with the electrical parameters, operation status and abnormal records
detected by the detector; Intelligent query, display and print chart.
Automatic detection can be realized by setting parameters of detection equipment.
4. Parallel function.
The
equipment is equipped with RS485 digital parallel interface, which is
controlled by the host and records the detection process.
5. Shutdown protection function.
On
the basis of general AC false load and load box, an intelligent control
system is added to detect and maintain the AC false load of diesel
generator set, which can set the protection of phase loss, overvoltage
and undervoltage. Once the parameters detected by the equipment exceed
the set parameters, the equipment will give an audible alarm and
automatically shut down for protection.
To sum up, in
order to effectively avoid the occurrence of accidents, users should
strengthen the daily detection and maintenance of power generator,
establish perfect detection and maintenance procedures of diesel
generator set, and regularly maintain the diesel generator set.If you
