Product Description

Portable frequency modulation series resonance AC withstand voltage automatic test system device
I work processUse range:
1. AC withstand voltage test of 10kV cable ≤ 10km (300mm2);
2. AC withstand voltage test for 35kV cable ≤ 3km (300mm2);
3. 1000MW (hydraulic) thermal power generator, AC withstand voltage test with electric capacity ≤0.5μF;
4. It can meet the AC withstand voltage test of 220kV/110kV/125000kVA neutral point graded insulation transformer.

II Feature
1) The interior is controlled by an embedded industrial computer, and the Chinese menu display man-machine dialogue operation function is optimized, and the operation is simple.
2) Automatically sweep the frequency to find the resonance point. The frequency range is 20~300Hz, and the sweep range can be manually set. The maximum sweep time is 1.5 minutes (full-frequency sweep). The frequency resolution is 0.01Hz
3) During the automatic test, the system will automatically track the resonance state of the system. When the resonance state changes and exceeds the set area, the system will automatically track the resonance point. Ensure that the system is working in the optimal output state during the entire process, and draw the frequency voltage curve during frequency modulation .
4) During automatic test, you can switch to manual frequency and voltage adjustment at any time
5) Automatically track the voltage when the voltage is withstand, and automatically adjust the voltage to the target voltage when the voltage fluctuates normally, and prompt the user when the voltage fluctuates abnormally, and the user will operate according to the test situation
6) Full voltage output protection: In the process of voltage regulation, strictly ensure that the variable frequency power supply will not output full voltage
7) The software has undergone strict simulation operation inspection, and the operation is safe, stable and reliable
8) Data query function, query past test data according to query conditions;
9) The LCD display can display the power supply voltage and current; the frequency and voltage of the high-voltage output,
10) Protection function: with power failure, overcurrent, overvoltage and flashover protection functions;
11) The internal structure of the variable frequency power supply and its components after normal road and rail transportation, the mutual position remains unchanged, no damage, no loose fasteners
12) Appearance and Chinese information display prompt operation interface fully adopts humanized design, beautiful and easy to operate.
