The oil cup insulation oil dielectric strength tester has introduced advanced technology from abroad. It is a high-precision, fully automatic oil testing device that integrates computers and microprocessors as core components. It has successfully overcome the difficulty of severe interference from strong electromagnetic fields on microprocessors, achieved mechatronics integration, and equipped the instrument with many functions such as automatic detection, automatic testing, automatic processing, and automatic printing. It has high testing accuracy, easy operation, safety and reliability, and adopts a combination of dry-type transformers. It has the characteristics of small size, light weight, beautiful appearance, and easy use.

The test method of the oil cup insulation oil dielectric strength tester mainly includes the following points, please refer to them:

1. Fully automatic testing method: Six consecutive tests are conducted, and the average value is automatically calculated. The data and average of the six tests are printed out through a panel printer.

2. Single automatic test method: Automatically complete one test and print out the single test data.

This machine uses an AC reversible motor to drive the voltage regulator at a constant speed of 3 kV/s through a boosting transformer. When the oil sample is broken down, the protection system automatically cuts off the boosting power supply circuit, and at the same time, the protection circuit provides an interrupt signal to the system. The system responds and executes the oil test breakdown program. Its main internal operations include:

4. The four digit digital display flashes continuously for 8 times, indicating the breakdown of the tested oil product;

5. Record experimental data;

6. Program controlled automatic execution of zero return operation. After returning to zero, the insulation oil dielectric strength tester identifies whether to proceed to the next test operation cycle or automatically exit the test state based on the number of tests.
