4、 Structural principles and performance characteristics

GJW-50DComputer controlled voltage breakdown testerMainly composed of: boost system (high voltage transformer), measurement system, A/D converter, discharge system, electrodes, oil tank, electrode positioning bracket, computer data processing system, software, etc.

5、 Computer systems and software packages

GJW-50DComputer controlled voltage breakdown testerThe test software is a powerful, easy to operate, and visually displayed test software system developed by our company. This instrument is 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.

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 EXECLFORD document for editing;

7. The software equipment personnel management function allows test personnel to set their own test items and parameters. After setting their own test content, others cannot enter the program:

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

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

6、 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. The DC test discharge alarm function will automatically sound when the test door is opened after the equipment completes the DC test. The alarm will be automatically cancelled after the discharge device on the equipment is used to discharge (note: not discharging after the DC test will endanger personal safety and prevent direct access to the electrode, reminding 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. The circuit of the experimental equipment is equipped with multiple protection measures, mainly including overcurrent protection, voltage loss protection, leakage protection, short circuit protection, DC test discharge alarm, etc

5. Level 6 high-voltage safety power-off control:

1. Main power switch

2 High voltage power-off switch (key switch)

Reset switch for regulator 3

4 Test box door safety switch

5 High voltage transformer input side current limiting circuit breaker

6. Leakage protection switch
