Series Resonant Device English Name:Brief Introduction for TPXB Series Resonant System

Series Resonant Device Principle: The series resonant test utilizes the series resonant principle, employing an excitation transformer to stimulate the series resonant circuit, adjusting the output frequency of the frequency converter to regulate the inductance of the circuit.The series resonance between L and sample C results in the resonant voltage being the voltage applied to the sample.

The TPXB series resonance test device, the frequency conversion series resonance device is mainly composed of a frequency conversion controller, excitation transformer, high-voltage reactor, high-voltage voltage divider, etc. The frequency conversion controller is divided into two categories: those above 20KW are console-type, and those below 20KW are portable box-type; it consists of a controller and a filter. The main function of the frequency conversion controller is to convert a fixed amplitude and frequency 380V or 200V AC power supply into a variable amplitude and frequency sine wave. It also provides power for the entire set of equipment. The excitation transformer's role is to increase the voltage output from the frequency conversion power supply to an appropriate test voltage. The high-voltage reactor L is an important component of the resonance circuit. When the source frequency equals 1/(2π√LCX), it resonates in series with the test item CX.

Series Resonant Configuration: The series resonant test setup includes: a variable frequency source, excitation transformer, reactor, voltage divider, capacitor, and control box.

Resonant Test Object: The Variable Frequency Series Resonant Test Device is suitable for10KV, 35KV, 110KV, 220KV, and 500KV polyethylene power cables AC withstand voltage tests. The harmonic resonance test device is suitable for 60KV, 220KV, and 500KV GIS AC withstand voltage tests. The harmonic resonance test device is suitable for large transformers, generator set power frequency withstand voltage tests; power transformer induction withstand voltage tests; ground resistance measurements.

Resonance Application Fields: Variable Frequency Resonance Test Devices are widely used in industries such as electricity, metallurgy, petroleum, and chemical engineering. Series Resonance Test Devices are suitable for the交接 and preventive testing of capacitive items with large capacity and high voltage.
