VI Touch screen control system, computer system, and software package

The touch screen control system is the latest feature developed by our company, with simple operation and intuitive display. This instrument adopts touch screen control and completes the power frequency voltage breakdown and power frequency withstand voltage test of insulation media through human-machine dialogue.

Touch screen operation interface

Touchscreen download interface

All experiments can be easily set through the touch screen, and the test results can be exported from a USB drive. But there will be no curve chart of the experimental process. If a curve chart is needed, a computer connection is required.

1. During the experiment, the test curve can be dynamically drawn, and the test curve can be overlaid with multiple colors for comparison, locally enlarged, and any section of the curve can be analyzed by enlarging the area;

2. Can edit and modify experimental data, flexible and applicable;

3. The experimental conditions and test results can be automatically stored;

4. The format of the test report is flexible and adaptable to meet the different needs of different users;

5. The validity of curve data in a set of experiments can be manually selected;

6. The experimental result data can be imported into Excel and edited in WORD documents;

7. The overcurrent protection device has sufficient sensitivity to ensure that the power is cut off within 0.1 seconds when the sample breaks down;

8. Durability of instrument operation: The instrument can operate continuously without the need for periodic shutdowns to protect it.

9. During the withstand voltage test, there is an automatic voltage stabilization function (not affected by fluctuations in the power grid voltage).

The experimental software is the latest functional, easy-to-use, and visually intuitive experimental software system developed by our company.

This instrument can also be controlled by a computer and completed through human-machine dialogue to perform power frequency voltage breakdown and power frequency withstand voltage tests on insulation media. This instrument belongs to our company

7 Safety instructions for high-voltage breakdown equipment:

1. The equipment needs to be equipped with a separate protective grounding wire. Grounding protection is mainly used to reduce the strong electromagnetic interference caused by the breakdown of the sample to the surrounding area. It can also prevent the computer from losing control.

2. DC test discharge alarm function: When the device completes the DC test, the device will automatically alarm when the test door is opened, and the alarm will be automatically cancelled after the discharge device on the device is used for discharge (Note: Since not discharging electricity after DC testing can endanger personal safety, the electrode cannot be directly taken to remind the user to discharge to avoid personal injury).

3. The experimental discharge device is integrated with the main unit, improving the previous function of having a separate discharge pole.

4. Security protection:

① Door lock protection

② Overvoltage and overcurrent protection

③ High voltage warning light

④ Emergency stop button

⑤ Discharge alarm

⑥ Leakage protection switch
