I. Overview
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. Moreover, it is small in size and
convenient to carry.
II. Key Function And Feature
1. With a microprocessor, automatically fulfill the withstand voltage test for oil circulation
with a range of 0 ～80KV (including boosting, maintaining, mixing, standing,
calculation, printing and other operations)
2. Display by large-screen LCD and prompt by English menu.
3. The instrument operation is simple. 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. Maintain power down. 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. With overvoltage, over current, limiting protection, in order to ensure the safety of
operators.
7. With a temperature measurement display function and system clock display.
8. Communicate with computer with a standard RS232 interface.（Optional）
