Main features of the complete set of variable frequency series resonance test device
1. Small size and light weight, suitable for on-site use
The variable frequency controller integrates voltage regulation, frequency modulation, control, and protection functions, eliminating the need for bulky voltage regulators, and is easy to operate with intuitive readings. Due to the high q-value of the system (30-120), it effectively solves the constraints of insufficient power capacity on on-site testing. When the voltage level is high, the reactor adopts a multi-stage or stacked structure, which is convenient for use, transmission, and on-site installation.
2. High installation reliability
The complete set of variable frequency series resonance test equipment adopts advanced design ideas, high-quality IGBTs and drive circuits to reduce output waveform distortion, improve frequency output stability, and has good IGBT, overcurrent, overvoltage (protection values can be manually adjusted according to needs), and discharge protection functions, which can protect the safety of equipment and personnel; When the test sample discharges or breaks down, due to the destruction of resonance conditions, the short-circuit current is small, only 1/q of the test current of the test sample, avoiding damage to the test sample caused by breakdown.
3. Good equivalence of the experiment
Using AC voltage close to the power frequency (30Hz-300Hz) as the test power supply, it is very close to the 50Hz/60ha power supply in terms of equivalence and consistency, ensuring the reliability and authenticity of the test results.
