KGXZ-B Generator Frequency Conversion Resonance Boost Device Cable Withstand Voltage Tester
Product Introduction
KGXZ-B generator frequency conversion resonance booster device can be used to adjust the inductance of the reactor to achieve the resonance state, can also be used to adjust the operating frequency of the system to achieve the resonance state, but also can be used at the same time to achieve the resonance state. 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.
Generator AC voltage test requires the use of power frequency voltage, the 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, most of the domestic test units use resonant transformers to test it. But the resonant transformer itself is very heavy, often tons, field test is very inconvenient. In view of this situation, an AC withstand voltage resonant booster device for frequency modulation and inductance modulation generator is designed and manufactured.
