Description
Many power systems, railway systems, large-scale petrochemical plants and enterprises have a lot of electrical equipment whose internal insulation are mostly oil-filled insulation type, and therefore, test on insulating oil dielectric strength is common and necessary.
To meet the needs of the market, we have developed and produced a series of insulating oil dielectric strength testers according to national standard GB/T507-2002, industry standard DL429.9-91 and the latest Electric Power Industry Standard DL/T846.7-2004 by ourselves. This instrument, by using a single-chip microcomputer as the core, can operate in full automation with high accuracy, greatly improving work efficiency and reducing the labor intensity of workers.
Features
1. With a microprocessor, automatically fulfill the withstand
voltage test for oil circulation with a range of 0~100KV (including
boosting, maintaining, mixing, standing, calculation, printing and
other operations).
2. Display by large-screen LCD and prompt by English menu.
3. Simple operation. The machine will automatically complete the
withstand voltage test on one cup of sample oil after simple
setting by the operator. Breakdown voltage value of 1 to 6 times
and recurrent times will be automatically saved. After the test,
the thermal printer will print each breakdown voltage value and
average value.
4. Power-down preservation. It can save 100 tested results and
displaying current ambient temperature and humidity.
5. Adopt a single-chip microcomputer to boost the voltage at an
even speed. The voltage is accurate at 50HZ, ensuring the whole
process easy for control.
6. Equipped with over-voltage, over-current and limit protections
to ensure the safety of operators.
7. With the function of displaying the measured temperature and
system clock.
8. Communicate with computer with a standard RS232 interface.
