Huazheng HZJQ-3 3 Cups 80kv Oil BDV Tester Transformer Oil Dielectric Strength Tester

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.

    I.Key Function And Feature

    1.With a microprocessor, three cups of a body, 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 has the advantages of simple operation, the operators only need a simple setup, instrument will automatically set in accordance with 1-3 oil sample pressure test. Each oil sample, each breakdown voltage value and the number of cycles will be automatically stored,after completion of the test, the thermal printer can print out the breakdown voltage value and average value

    4.Maintain power down, can store 100 experimental results, and can display the current environment temperature and humidity.

    5.Using single chip microcomputer control speed boost, voltage frequency accuracy to 50HZ, makes the whole process easy to 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.

    III.Maintenance

    1.This equipment shall not be exposed in moist environment.
    2.Keep the oil cup and the electrodes clean. Fill the cup with fresh transformer oil for protection during its idle. Check the electrode distance and check the tightness between the electrode tip and electrode bar screw thread before the cup is used again.
    3.Instrument oil Cup box high voltage electromagnetic switches are oil-filled insulation, there should be regular observation oil surface, through transparent switch shell, as oil surface at distances from the top of more than 10MM, should unscrew the plugs supplemented in line with the GB2536 25th of transformer oil.
