II. Functional Overview
1. The 6801/2021 model features a single oil cup structure. Controlled by a microcontroller, it can automatically complete a series of operations such as voltage rise, hold, voltage drop, stirring, static settling, display calculation, and printing. It can perform insulating oil withstand voltage tests in the range of 0-80kV.
2. It adopts a large-screen dot matrix liquid crystal display with an internal backlight system, making it clearly visible even at night. The test process is guided by Chinese menu prompts, facilitating operation for test personnel.
3. This instrument is simple to operate; operators only need to input simple commands according to the instructions, and the instrument will automatically complete the insulating oil withstand voltage test according to the settings. Each breakdown voltage value is automatically stored. After the test is completed, the printer is activated to print out each breakdown voltage value and the average value.
4. This instrument is equipped with both automatic and manual test modes. Test parameters can be set before testing, greatly enhancing the practicality of the instrument.
5. This instrument has strong adaptability and is easy to carry, suitable for laboratory and outdoor field testing. It also has strong anti-interference capability and can operate normally in strong electromagnetic environments.
6. This instrument is equipped with protective devices such as overvoltage, overcurrent, and automatic zero return, ensuring the safety of the instrument itself and operators under normal usage conditions.
7. The voltage rise speed can be selected according to different experimental standards.
