Power frequency voltage breakdown tester

Applicable materials:

SDJ-100KVPower frequency voltage breakdown testerMainly suitable for testing the breakdown strength and withstand time of solid insulation materials such as plastics, films, resins, mica, ceramics, glass, insulation oil, insulation paint, cardboard and other media under power frequency voltage or DC voltage; The voltage breakdown tester is controlled by a computer, and the test curve can be observed online during the test process; Automatically store test conditions and test results data, and can access, display, and print them.

Basic functions:

The voltage breakdown tester is controlled by a computer, and the data acquisition method is through photoelectric isolation, effectively solving the anti-interference problem during the test process. The software is easy to operate and can display dynamic curves in real time. At the same time, the boost rate is infinitely adjustable, and the boost rate can be adjusted according to one's own needs, making the boost rate truly uniform and accurate, and accurately testing the leakage current data. Real time drawing of experimental curves, display of experimental data, accurate judgment, and the ability to save and analyze. Print the test data report. And it can automatically determine the breakdown of the sample and collect breakdown voltage data and leakage current. At the same time, it can quickly reduce the voltage and automatically reset to zero at the moment of breakdown. The software system is easy to operate, has stable performance, and is safe and reliable.

Structural features:

1. Mainly composed of: boosting system (high-voltage transformer), Siemens PLC control system, electrodes, oil tank, electrode positioning frame, computer data processing system, software, etc;

2. Computer - Siemens PLC Control System - Voltage Regulating Device - Step up Transformer - Sample;

3. High voltage transformers mainly generate the DC voltage required for the sample;

4. A voltage regulator is used to regulate the input voltage of a step-up transformer to generate the required input voltage for high voltage;

5. Voltage measurement is mainly measured from the measuring end of the high-voltage transformer, which is linear with the measuring end of the high-voltage transformer;

6. The discharge system will automatically discharge after the experiment is completed to avoid the harm of discharge to personnel.
