Abstract

Present, the secondary equipment test of substation mainly adopts the separation test and the overall flow method. The main reason for the failure to achieve the overall test is limited to high power current amplifier technology. On the one hand, it is because the amplifier is bulky, heavy, the power supply is high, and the installation of the substation is difficult to move. On the other hand, large current output amplitude, load, current accuracy and current response speed cannot meet the requirements. Based on the high power MOSFET fast amplifier technology can achieve 2000A current amplifier output current, output current response speed is less than 500 us at the same time, small volume, light weight, mobile convenience, make the secondary equipment at the scene of the whole test to become a reality, the substation debugging maintenance is of great significance.
