All types of diesel generator sets and UPS (Uninterruptible power Supply) are used as emergency backup power sources in case of power failure or power outage in the city. Most of the time, diesel generator sets and UPS (uninterruptible power supply) are in standby mode. Once there is a power outage, the diesel generator set is required to start power supply immediately; otherwise, the standby diesel generator set will lose its significance.
Practice has proved that only by strengthening the daily inspection and maintenance of diesel generator sets can accidents be effectively avoided. Only by establishing a complete set of inspection and maintenance regulations for diesel generator sets and conducting regular and standardized maintenance, upkeep and inspection of diesel generator sets can we prevent problems before they occur.
According to a new survey conducted by numerous grassroots maintenance personnel, the common technical challenge in current power supply maintenance work is that the detection of output power and various electrical characteristic parameters of various diesel generator sets and UPS equipment has never been effectively and smoothly carried out with high-power AC dummy loads. It is only after a power supply failure occurs that it is known that the performance of the diesel generator set or the UPS(uninterruptible power supply) has gone wrong.
1. Application of AC dummy load for the inspection and maintenance of diesel generator sets
Testing diesel generator sets
Unbalanced load capacity Steady-state voltage regulation rate Steady-state frequency regulation rate Transient voltage regulation rate Transient frequency adjustment rate Voltage recovery time; Frequency recovery time Continuous operation detection of diesel generator sets.
Note: The electrical characteristics are automatically detected, and the data is calculated independently by the computer of the load itself.
Test UPS
Output voltage stabilization accuracy; Output voltage unbalance degree; Dynamic voltage transient range Overload capacity; Switching time of mains battery; Bypass inverter switching time; Backup time.
Note: The electrical characteristics are automatically detected, and the data is calculated independently by the computer of the equipment itself.
Ii. Main Functions of AC Dummy Loads for the Inspection and maintenance of Diesel generator Sets
Shutdown protection function: The AC dummy load for diesel generator set detection and maintenance is based on the general AC dummy load and load box, and is equipped with an intelligent control system. It can set protection for phase loss, overvoltage and undervoltage, etc. Once the parameters detected by the equipment exceed the set parameters, the equipment will issue an audible alarm and automatically shut down for protection.
Intelligent control and data processing functions
(1) Automatic detection can be achieved by setting the parameters of the detection equipment.
(2) Online monitoring of the electrical parameters of the equipment under test.
(3) Data transfer: After the detection is completed, the collected data can be transferred to a USB flash drive.
(4) Data processing software function: The data processing software is used in conjunction with the detector. The detection parameters can be set to analyze and process the various electrical parameters, operating status and abnormal records detected by the detector. Intelligent query, display and print of charts.
Query function: Query the detection data of diesel generator sets and retrieve abnormal records.
Online communication: The detector can be connected to the upper computer via RS232/RS485 interfaces.
Parallel operation function: Products of the same model can be paralleled. This device is equipped with an RS485 digital parallel interface, which is uniformly controlled by the main unit and records the detection process.
