The use of DC system comprehensive characteristic tester
The device is a combination of years of research and development results and long-term on-site operation experience, and the integration of relevant advanced technology at home and abroad. The device can realize the detection and test of the capacity of chargers of different capacities and battery packs of 500 a·h and below, and can accurately and reliably test the voltage stabilization accuracy, current stabilization accuracy, ripple system, discharge capacity and other parameters of the DC power supply system of the substation.
The system uses an updated PC as the host, equipped with LCD monitors, microprinters and other equipment. Through the long-term actual operation of the site, it is shown that the device has the advantages of perfect function, strong anti-interference, high reliability, good transparency, simple structure and easy to carry.
The main functions of the DC system comprehensive characteristic testerand features
Fully automatic test, the device completes various test functions according to the menu.
The host system adopts a new high-speed industrial PC as a processor and a large-scale integrated circuit (CPLD), with high reliability and excellent performance.
Comes with a large screen graphic LCD, 56-inch color screen, full Chinese graphic interface, simple to operate, easy to use.
Three-phase automatic numerical control voltage regulator is adopted, with high output accuracy, high power and high voltage stability.
The new high-power power consumption device is used as the load, with strong load capacity, high precision, small size, light weight, and no open flame in discharge. The structure adopts an integrated design, which is easy to carry.
The load resistors are arranged in an orderly manner with 8421 yards, which can be arbitrarily combined to meet the load required by the user.
During the discharge process, the discharge current remains constant at all times.
It only uses three keys to complete the setup, directly enters the numbers, prints on site, and has RS232 and USB interfaces.
Perfect upper computer function, with analysis, data saving, comparison and fault determination functions.
