Structural principles and performance characteristics:

工频交直流耐电压试验仪  1. It mainly consists of a boost system, a measurement system, an A/D converter, a discharge system, electrodes, an oil tank, an electrode positioning frame, a computer data processing system, software, etc;

2. Computer - A/D converter - Measurement and 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 discharges after the experiment is completed to avoid the harm of discharge to personnel; After the experiment is completed, there may still be residual high voltage in the machine components, which can cause fatal injuries to people. Equipping this rod can effectively solve this safety hazard.

Scope of application:

Mainly suitable for testing the breakdown strength and voltage resistance of solid insulation materials (such as plastics, rubber, laminates, films, resins, mica, ceramics, glass, insulation paints, and other insulation materials and components) under power frequency voltage or DC voltage.

Controlled by a computer, it is a brand new third-generation dielectric breakdown detection instrument independently developed by our company. The electronic control system is controlled by Siemens PLC, and the data acquisition method is optically isolated, 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 can be infinitely adjusted according to one's own needs, with a range of 10V-5000V/S, which is in a leading position in China (the only manufacturer in China that can achieve this function), making the boost rate truly uniform and accurate, and accurately measuring the data of leakage current. Real time drawing of experimental curves, display of experimental data, accurate judgment, and the ability to save, analyze, and print experimental data.

This system can automatically identify sample breakdown 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.

safeguard:

The electric breakdown tester has relatively complete safety protection measures:

1. Threshold protection: If the door is not closed, even if the power on point experiment starts, the device will not respond, and the software will prompt that the safety door is not closed.

2. Voltage zeroing protection: If there is a sudden power outage during the experiment, it will automatically return to zero position after the next power on, ensuring that the initial voltage is at zero position

3. Termination voltage protection: The termination voltage can be set through software to ensure that if there is an abnormal rise to the specified voltage during the boosting process, it will automatically terminate and return to zero

4. High voltage mechanical limit: If the software system loses control, the voltage continues to rise and automatically returns to zero after reaching the high voltage limit

5. If the fault is not stopped after breakdown, data is collected through an overcurrent protector to ensure that the voltage automatically returns to zero

6. There is a high voltage indicator light, and by observing the status of the indicator light, it can be determined whether the actual boost is at zero position or not

7. If conducting experiments for a long time, in order to ensure the good operation of the equipment, the equipment should have a transformer exhaust port to ensure the good operation of the transformer,

Increase service life
