The Application Research Of The Direct Current Power's Computer Management Detection Device

With the rapid development of Power System in our country in recent years, we need more stability and reliability about it. However, the electric substations have more influence on the stability of the power system. And the DC currents is very important to inferior facilities and real time communications. So it is very important to check the parameters of the DC currents. At the same time, there are lack methods to check those parameters. Fortunately, we will be glad to look forward the new device.Nowadays, the DC power's technical indexes are provided by the factory. As the time goes on, the technical index will move out of the normal according to the practice. The typical result is the 3-indexes overflow because of the indexes of refresh device decline. It will make battery lose efficacy or damage if the 3-indexes changing have not fond and adjusted in time.The domestic DC current check system is all fixed facilities, such as fixed adjusting voltage and load box. whose volume and weight are so big that moving, checking and analysis are inconvenience. Moreover, the voltmeter current meter and oscilloscope's cord complexity should not be ignored. so it is not suitable for electric substation by mobile used.Our DC current check system is act in accordance with the nation's technical rules. It adapts the multi-meters made in America to accomplish the data acquisition. The maximum, the minimum, the average value, the stabilized voltage precision, the stabilized current precision and the ripple factor are counted revealed and saved through the development of the software dealing with the data. The last three parameters is especially important to keep up the DC current facilities and the safety of the person who work on those. At last, I am glad to see that the DC current check system is so reliable simple and easy-operation.
