Series Resonant Device (in English: Series Resonant Device)Brief Introduction for TPXB Series Resonant System

Series Resonant Device Principle: The series resonant test utilizes the principle of series resonance. It employs an excitation transformer to energize the series resonant circuit, adjusts the output frequency of the frequency converter, and makes the inductanceLNo Chinese content provided.CSeries resonance, the resonance voltage is the voltage applied to the test sample.

TPXBThe series resonant test device, the frequency conversion series resonant device is mainly composed of a frequency conversion controller, excitation transformer, high-voltage reactor, high-voltage voltage divider, etc. The frequency conversion controller is further divided into two main categories.20KWAbove is the console version.20KWBelow is the portable box; it consists of a controller and a filter. The variable frequency controller's primary function is to keep both the amplitude and frequency constant.380VOr200VIndustrial frequency sine AC is converted into a sine wave with adjustable amplitude and frequency. It also provides power for the entire set of equipment. The excitation transformer's role is to boost the voltage from the frequency conversion power supply to the appropriate test voltage. High-voltage reactorLIt is an important component of the resonant circuit, when the power frequency equals1/(2π√LCX)At the time, it was in relation to the sample.CXA series resonance has occurred.

Series Resonant Configuration: The series resonant test setup includes: variable frequency power supply, excitation transformer, reactor, voltage divider, capacitor, and control cabinet.

3Our system supports multiple testing modes."Auto-tuning + Manual Pressure Regulation"，"Auto-Tuning + Auto-Pressurizing"，"Manual Tuning + Manual Pressure Adjustment"待试验模式，recommend using"Auto-tuning + Manual pressure adjustment"The model allows for rapid identification of resonance points while enabling manual voltage control during the testing process, enhancing safety.

4The human-machine interaction interface of the series resonance system is user-friendly. Test parameter settings, control, and results are displayed on the same screen, offering a clear and intuitive view, with features such as automatic timing and operation prompts. The system features full touch screen operation and display, and is equipped with test data saving and query functions.

5Enhanced protective features. Series resonant circuit equipped with zero-point protection.(The system is prohibited from starting if the voltage output control knob is not in the zero position.)Overvoltage protection, overcurrent protection, and flashover protection features ensure system reliability.
