1) The frequency conversion power supply is placed vertically and horizontally, especially suitable for field operation and observation;
2) The interior and exterior are equipped with special shock-absorbing rubber support feet and protective aluminum boxes, which can effectively slow down the bumpy vibration during transportation and the impact during hoisting. To ensure the long-term stability and reliability of the inverter power supply;
3) Parameter display: Touch or external mouse large screen LCD interface display system can display resonance voltage (that is, the target voltage set before the test), test frequency, measurement frequency, low voltage, low voltage current, voltage withstand time, overvoltage protection, overcurrent protection, flashover protection, stage boost and stage timing, operation mode switching, capacitance, inductance, The frequency exchange calculation, parameter query, etc., can also display the frequency curve, voltage curve, etc., can intuitively judge the accuracy and stability of the resonant frequency of the test;
4) Parameter setting: Large screen touch LCD color screen and external mouse can directly complete the setting of various parameters, starting frequency, ending frequency, starting voltage, stage boost and timing, measuring voltage divider ratio, excitation ratio, overvoltage protection, overcurrent protection, flashover protection, test mode, capacitor and inductance frequency exchange calculation, parameter setting tips and help and other parameters can be set or selected.
5) Test mode: touch screen and external mouse operation, automatic, semi-automatic, manual three operating states. With boost voltage, tuning (including manual, automatic), segmented pressure and timing, operating status, mode switching, fault warning, capacitance and inductance frequency exchange calculation function;
6) Protection functions and information tips: with high voltage overvoltage protection, low voltage overcurrent protection, overcurrent protection, and mismatch protection, zero, flashover protection, emergency shutdown, undervoltage protection and other multiple protection functions;
7) Data storage function: save test results (manually save), print, upload, check back, etc
Test result: After the manual or automatic test is completed, the detailed parameters of the test can be displayed in the test result interface. When the test is interrupted, the interrupted state can be prompted. The parameters can be stored in the memory, the memory is non-volatile memory, can store 50 test records;
Data query: the saved test result data can be displayed on the screen, and with a USB interface, the data can be printed out or printed by the printer carried by the device; (The printer is selected by the customer, if the customer has this demand, it must be specifically stated in the contract)
8) Automatic voltage regulation function: the system automatically tracks and maintains a stable test voltage according to the set test voltage or the manual boost result, and the voltage stability can reach 1.0%;
9) The frequency range and frequency resolution can be set: the frequency range can be set to 30 ~ 300Hz, 45 ~ 100Hz, 200-300Hz, on demand, can speed up the tuning process; The frequency resolution can be preset to 0.1Hz, 0.2Hz, 0.5Hz, or 1.0Hz, as required, to achieve an optimal balance between tuning efficiency and tuning accuracy;
10) Frequency adjustment is divided into coarse and fine adjustment, and can automatically find the test resonance point to ensure that the resonant frequency does not drift during the test; P) Weight: about 12kg; 3, high voltage reactor 45kVA/45kV 6 knots
