Product Introduction: Series Variable Frequency Resonant Test Set
It consists of a variable frequency power supply, an excitation transformer, high-voltage reactors, and a capacitive voltage divider. The capacitance of the test object and the reactor form a series resonant connection; the voltage divider is connected in parallel with the test object to measure the resonant voltage across it and provide overvoltage protection signals; the frequency-modulated power output is coupled to the series resonant circuit through the excitation transformer to provide the excitation power for series resonance.
Product Functions: Series Variable Frequency Resonant Test Set
1) The variable frequency power supply is placed both vertically and horizontally, making it particularly suitable for on-site operation and observation;
2) Both internal and external special shock-absorbing rubber support feet and protective aluminum cases effectively reduce vibration during transportation and impact during lifting, ensuring long-term stability and reliability of the variable frequency power supply;
3) Parameter display: touch screen or external mouse large-screen LCD interface display system
It can display resonant voltage (i.e., the target voltage set before the test), test frequency, measured frequency, low-voltage voltage, low-voltage current, withstand voltage time, overvoltage protection, overcurrent protection, flashover protection, step voltage increase and step timing, operation mode switching, capacitance, inductance, frequency interchange calculation, parameter query, etc. It can also display frequency curves, voltage curves, etc., allowing intuitive judgment of the accuracy and stability of the resonant frequency during the test;
4) Parameter setting: the large-screen touch LCD color screen and external mouse directly complete the setting of various parameters, including start frequency, end frequency, start voltage, step voltage increase and timing, measurement voltage divider ratio, excitation transformer ratio, overvoltage protection, overcurrent protection, flashover protection, test mode, capacitance-inductance frequency interchange calculation, parameter setting prompts, and help;
5) Test modes: touch screen and external mouse operation, with three operating states: fully automatic, semi-automatic, and manual. It has functions such as voltage increase, tuning (including manual and automatic), step voltage application and timing, operating status, mode switching, fault indication, capacitance-inductance frequency interchange calculation, etc.;
6) Protection functions and information prompts: multiple protection functions including high-voltage overvoltage protection, low-voltage overcurrent, overcurrent protection, detuning protection, zero position, flashover protection, emergency stop, undervoltage protection, etc.;
7) Data storage function: test result saving (manual save), printing, uploading, and recall, etc.
① Test results: after manual or automatic test completion, the detailed parameters during the test can be displayed on the test result interface. When the test is interrupted, the interruption status can be indicated. The parameters can be saved in a non-volatile memory, which can store 50 test records;
