AC Withstand Voltage Test Device Dynamics - Yangzhou Darui
Darui Electric recommends for you
l Parameter setting: The large-screen touch LCD color screen and external mouse can directly complete the setting of various parameters. Parameters such as start frequency, stop frequency, start voltage, step-up and timing, measurement divider ratio, excitation transformer ratio, overvoltage protection, overcurrent protection, flashover protection, test mode, capacitance-inductance frequency interchange calculation, parameter setting prompts, and help can be set or selected.
l Test mode: Touch screen and external mouse operation, with three running states: fully automatic, semi-automatic, and manual. It has functions such as voltage boosting, tuning (including manual and automatic), step-up and timing, running status, mode switching, fault indication, capacitance-inductance frequency interchange calculation, etc.
l Protection functions and information prompts: It has multiple protection functions such as high-voltage overvoltage protection, low-voltage overcurrent and overcurrent protection, as well as detuning protection, zero position, flashover protection, emergency stop, undervoltage protection, etc.
l Data storage function: Test results can be saved, printed, uploaded, and reviewed.
a. 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 prompted. The parameters can be saved in a non-volatile memory, which can store 50 test records.
b. Data query: The saved test result data can be displayed on the screen. It also has a USB interface, which can output and print data or print using the printer carried by the device.
l Automatic voltage stabilization function: The system automatically tracks and maintains a stable test voltage based on the set test voltage or manual voltage boosting result, with voltage stability up to 1.5%.
l Frequency adjustment range and frequency resolution can be set: The frequency adjustment range can be set to 20-300Hz, 45-65Hz, 50Hz, or as needed, which can speed up the tuning process; the frequency resolution can be preset to 0.1Hz, 0.2Hz, 1.0Hz, or 2.0Hz as needed, achieving an optimal balance between tuning efficiency and tuning accuracy.
Frequency adjustment is divided into coarse and fine adjustment, and can automatically find the test resonance point, ensuring that the resonance frequency does not drift during the entire test process.
