Engineering acceptance and routine maintenance of discharge equipment such as generators and UPS
In many industries, backup power is often referred to as the heart of the power system. Maintenance and management departments at all levels must pay attention to the maintenance and inspection of backup power from the perspective of ensuring equipment operation quality, production safety, and property safety. A good backup power system is an important force in dealing with disasters. Natural disasters such as typhoons and earthquakes often damage power supply lines, and reconstruction of these lines often takes some time. In the face of disasters, power outages mean interruptions in information, interruptions in light, and even interruptions in life. At this time, power backup oil generators, UPS (uninterrupted power supply), storage batteries and other backup power sources must prop up the power girders of the emergency system.
Currently, there are problems that are urgently needed to solve: According to investigations by many grassroots maintenance workers and users, the maintenance technical problems that currently prevail in maintenance work are: output power and load carrying capacity of various types of generator sets and UPS equipment. The inspection work has not been able to proceed smoothly.... It is only after the power failure occurs that it is known that there is a problem with the backup power supply performance. Then how to solve this problem, the current industry will use the corresponding power load box to carry out aging tests, then what are the functions of the load box? What can be applied? We take the ALB-SR series AC three-phase resistive load box of Ningbo Hangmao Electric Equipment Co., Ltd. as an example.
Engineering acceptance and routine maintenance of discharge equipment such as generators and UPS
I. Outstanding application in daily maintenance testing and engineering acceptance of diesel generator sets/turbine generator sets All kinds of generator sets are used as emergency backup power supply providers after mains failures. Most of the time the generator sets are in stand-by standby mode. In the event of a power outage, the generator set is required to immediately start the power supply, otherwise the standby unit will lose its significance! Practice has proved that strengthening routine maintenance testing is effective in avoiding accidents. Many serious faults and accidents are often caused by small maintenance negligence. Only well-established maintenance procedures and regular and regular inspections of generator sets are required to prepare them for disaster prevention and prevent accidents before they occur. The AC dummy load provided by Hangmao Electric can accurately detect the output power and load capacity of various types of generator sets.
The AC load box can help users effectively achieve various types of generator maintenance testing:
1, accurate detection of diesel generator output power and load capacity.
2. When the new generator set project is accepted, it is checked whether it can meet the design requirements.
3. After retrofitting the noise reduction equipment such as muffler installed in the generator set, it is tested whether the output power of the generator set can meet the operational needs of the power equipment.
4. 100% has sudden/intrusion unloading detection function, which can effectively test the running test of the generator set in various working environments.
5. After overhauling the generator set, test whether its output power, load capacity and other performance indicators meet the requirements.
6. Routine maintenance routine inspection of the generator set, according to the requirements of the newly issued backup power supply maintenance regulations, the diesel generator should be loaded for 15-30 minutes every six months.
Second, the UPS equipment in the field of routine maintenance testing, engineering acceptance of the outstanding application of the quality of the UPS is also good for life, there will be aging components, there will be various types of failures, practice has proved that routine maintenance testing can effectively reduce the occurrence of failure Effectively avoid accidents and effectively extend the service life of equipment. Do not ignore periodic inspections because the UPS is highly intelligent, online, and maintenance-free. Routine maintenance and inspection work is an important part of the safe operation of the equipment at all times to avoid accidents. Ensure that you do not wait until the UPS fails to cause major safety incidents before you know the importance of routine maintenance testing. The AC dummy load provided by Hangmao Electric can accurately test the output power and load capacity of various types of UPS equipment.
Can help users to fully test UPS power:
1, 100% accurate and effective detection of UPS equipment output power and load capacity.
2. It is applied to the acceptance of newly installed UPS projects, and comprehensively tests the power supply capacity, output power, and power supply quality of the UPS system, and comprehensively checks whether the UPS inverter, regulator, and battery performance meet the design requirements.
3. It is applied to routine maintenance and routine monitoring of UPS equipment. According to the requirements for the routine maintenance of backup power supply, the UPS equipment shall be tested for verification discharge tests every year.
Third, detection of AC voltage regulator, inverter, switching power supply and other communication and communication equipment output power and load capacity
