It consists of a variable frequency power supply, an excitation transformer, a high-voltage reactor, and a capacitive voltage divider. The capacitance of the test object and the reactor form a series resonance connection; the voltage divider is connected in parallel to the test object to measure the resonance voltage on the test object and serve as an overvoltage protection signal; the frequency-modulated power output is coupled to the series resonance circuit through the excitation transformer to provide the excitation power for series resonance.
Product Features:
1. The frequency modulation and power components use imported components;
2. Fully utilize the company's existing resources, and independently develop, design, and produce all components of the equipment: variable frequency power supply, excitation transformer, high-voltage reactor, capacitor compensator, and high-precision capacitive voltage divider;
3. 35KV Variable Frequency Series Resonance Test Complete Equipment Price, with multiple functions of fully automatic (automatic tuning, automatic voltage boosting), fully manual (manual tuning, manual voltage boosting), and semi-automatic (automatic tuning, manual voltage boosting and manual tuning, automatic voltage boosting), which can be switched arbitrarily;
4. Equipped with settings for test voltage, pressurization time, alarm voltage setting, frequency range, and starting voltage;
5. Equipped with discharge protection function. In the event of flashover on the test object or sudden detuning of the resonance circuit due to other reasons, the variable frequency control power supply immediately and automatically cuts off the output and displays the protection type.
6. Measures and displays output voltage, output frequency, pressurization time, protection action type, and other related information. When the test is completed, the voltage automatically drops to zero;
7. LCD full Chinese interface platform technology, full touch screen operation, data saving.
The excitation transformer couples to the series resonance circuit to provide the excitation power for series resonance.
