KGXZ-A Generator Resonance Device AC Electric Magnetic Analyzer Wave Pulse Generator ISO9001
Product Introduction
The KGXZ-A generator frequency conversion series resonance test device can achieve the resonance state by adjusting the inductance of the reactor, or by adjusting the operating frequency of the system, and can also achieve the resonance state by using the above two ways. When the required frequency is tested, the frequency of the excitation source is adjusted to the required frequency, and then the inductive reactance of the reactor is adjusted according to the capacitance of the subject, so that the system resonates and generates high voltage. In the process of boosting voltage, if the resonant point deviates, the resonant point can be accurately found by fine-tuning the frequency to ensure a high Q value. Thus, the power supply capacity and the volume weight of the test equipment are reduced to the greatest extent.
KGXZ-A generator AC voltage test requires the use of power frequency voltage, the current national standard frequency of power frequency voltage is defined as 45Hz ~ 65Hz, but in many test occasions, the generator is required to carry out 50Hz±2Hz AC test, and the generator stator winding to the ground power capacity is relatively large, At present, most of the domestic test units use resonant transformers to test it, but the resonant transformer itself is very heavy, often tons, and the field test is very inconvenient. In view of this situation, our company has designed and manufactured a frequency modulation induction generator frequency conversion series resonance test device.
