Intelligent AC dry load box Main features and functions ①. Intelligent AC generator dry load box to measure the steady-state phase voltage, current, active power, reactive power, apparent power, power factor, frequency, running time and other basic function. ②. Intelligent AC load box not only dry all stable state parameters, but also the load increase, unload, voltage, current, frequency curve, and voltage and current harmonic curves and harmonic content. ③. Intelligent AC dry load box used in conjunction with the host computer, you can automatically complete measurement of all the electrical parameters of the generator. Automatically generate a variety of charts, graphs and test report. Standardized operation, authoritative. Content-rich data, reports applicability and can be based on user needs the signature changed format. AC dry load box loading inductive or capacitive load function (according to user needs, separate design). Over control either by computer control, and manual control on the panel. Intelligent control, automatic test generator set various parameters including the dynamic parameters. For high-power generators to provide a scientific means of detection. (:) Diesel generator sets using data only with a full load to run in order to show a real load capacity. According to many users reflect the current backup diesel generator maintenance and use, due to various reasons, the prevalence can not 'true' to detect the load carrying capacity of the generator set this phenomenon. To this end the company produced AC adjustable moving load box ('the AC load box'), with the 'fake' load to solve this problem. I produced the AC load box can accurately detect the output power and load capacity with all kinds of turbines. Dummy load generators for the following conditions:.. ① relatively long time to detect the output power and load capacity with diesel generating sets; ② acceptance of newly installed generating units, to detect the output power can meet its requirements; ③. generators room to install silencer, after the transformation into the exhaust noise reduction measures, to detect the output power is affected;. ④ diesel generators after repair, test the output power, load capacity and other performance indicators to meet the requirements; ⑤. generators daily maintenance routine testing, according to the new regulations issued by the backup power supply maintenance requirements of diesel generators to load test machine per year from 60 to 130 minutes. ? AC adjustable moving load box Overview: The load box is mainly used for electric power, telecommunications and other sectors and manufacturers of power-line UPS (uninterruptible power supply) and performance test generator sets, aging and other occasions. It is a device with a carrying capacity of important practical testing and maintenance of equipment. Its application effectively avoid economic loss reserve units or enterprises failed to start due to the power, but also provide a scientific basis for the new unit with a carrying capacity of detection and acceptance of the new battery. ?
