Thin film weak point testing and detection device

Product model: DRD-10KV

• Implementation standard: GB_T 13542.2-2009 IEC 60674-2:1988- Thin films for electrical insulation - Part 2: Test methods

Product Usage

This instrument is mainly used for automatically boosting the breakdown points per square meter of insulation materials such as polyurethane film, plastic film, and polypropylene film for electrical purposes under a given DC voltage.

This instrument is controlled by a microcomputer, and the speed of film rolling can be set. The voltage is increased according to the set rate. After reaching the set voltage, the current voltage and current values are recorded in real time, and the current breakdown point can be recorded in real time. After the test is completed, it automatically resets to zero, counts the number of weak points and weak lines, and calculates the number of weak points per square meter.

This instrument has a high degree of automation, simple operation, convenient installation of film rolls, and a floor standing structure for easy operation.

Structural composition:

1. Boosting component: A 0-10KV boosting part composed of a voltage regulator and a high-voltage transformer.

2. Moving parts: Use a voltage regulator to uniformly increase the voltage to the set value.

3. Detection component: a measurement circuit composed of integrated circuits that detects and transmits real-time measurement data to a computer.

4. Computer software: transmits the measurement and control signals collected by the detection equipment to the computer through intelligent circuits. The computer controls the operation of the equipment and processes the test results based on the collected information.

5. Rolling and unwinding: fixing the film and rotating it at a set speed

Equipment working principle:

The test voltage of this tester is 0-10KV DC voltage, with a fluctuation of ± 1%. The tester recovers the voltage to the originally set voltage within about 0.1 seconds after the weak point of the sample is broken down. The copper roller serves as the lower electrode, and the conductive rubber serves as the upper electrode. The film moves at a speed of 2m-5m/min, and when the weak point of the film breaks down, the breakdown point automatically accumulates and counts. The membrane movement is automatically counted in square numbers.

Advantages and Characteristics:

1. Easy to operate: After fixing the roll in and out, click to start automatic testing

2. Dynamic display: After the thin film is broken down, the dynamic display curve is synchronized for intuitive visualization

3. Easy installation: Place the mold roll into the inflation shaft, and the ventilation will automatically fix it

4. Adjustable tension: can adjust the tension of winding and unwinding in real time

5. Multiple modes: testing area/testing length/testing time

6. Breakdown point determination: Real time recording of data on electrical weak points and test lengths, which can be used to statistically query the length between electrical weak points

7. Automatic storage: After the introduction of the experiment, an automatic pop-up window will prompt the storage of data

8. Intelligent automation: This machine is highly intelligent and automated, and can be operated without professional training
