Product Introduction
The KDCJ-20kV impulse withstand voltage tester is one of the basic items for high-voltage testing of power equipment. After design, manufacturing, and repair, power equipment requires impact testing to verify or inspect. Therefore, impulse voltage test equipment has a wide range of applications, and different specifications of impulse test equipment can be seen in factories, research institutions, and high voltage laboratories in colleges and universities. The impulse voltage test system is a test equipment that simulates pulsed high voltage. In real life, pulsed high voltages are often encountered. For example, when lightning strikes and lightning strikes in nature, very high pulse currents and voltages will appear at the place where the lightning strikes, and high pulse voltages will also be induced around; For example, switching operations of switching devices in power systems can also lead to transient pulse voltages. These transient pulse voltage amplitudes often range from tens of kilovolts to hundreds of kilovolts, which can lead to equipment damage and endanger personal safety. On the other hand, simulating natural lightning phenomena to study the discharge mechanism is also of great significance.
The KDCJ-20kV Impulse Withstand Voltage Tester is an intelligent control and detection system designed specifically for the high-voltage impulse generator produced by our company. It uses programmable controllers and computer technology in technology, and the control and measurement functions are automatically realized, thus simplifying the system composition and greatly improving the reliability of the system, which enhances the safety of the system in high-voltage and high-current tests, Avoid equipment that may be exposed to high-voltage discharge transients. The operation interface has good man-machine dialogue function, convenient and simple operation process, and has the characteristics of intelligence.
