In power systems, railway systems and large petrochemical plants and mines, enterprises have a large number of electrical equipment, the internal insulation is mostly oil-filled insulation, dielectric strength of insulating oil is a routine test. In order to meet the needs of the market, our company has developed and manufactured a series of dielectric strength testers for insulating oil according to national standard GB/T507-2002, line standard DL429.9-91 and the latest power industry standard DL/T846.7-2004. The instrument is based on a single-chip micro-computer. It realizes all automation of testing, has high measurement accuracy, greatly improves work efficiency, and also greatly reduces the labor intensity of staff.

1. This instrument uses microprocessor and six cups in one. It can automatically complete the operation of boosting, holding, stirring, static placing, calculation and printing. It can carry out oil cycle pressure test in the range of 0-80 kV.

2. Large screen LCD display, Chinese menu prompt.

3. The instrument is simple to operate, and the operator only needs simple settings. The instrument will automatically complete 1-6 oil samples withstanding pressure test according to the settings. Each oil sample will be automatically stored for each breakdown voltage value and cycle number. After the test is completed, the thermal printer can print out the breakdown voltage value and average value of each oil sample.

4. To keep power off, 100 experimental results can be stored, and the current ambient temperature and humidity can be displayed.

5. Uniform step-up voltage is controlled by single chip computer, and the voltage frequency is accurate to 50HZ, which makes the whole process easy to control.

6. It has the protection of over-voltage, over-current and limit to ensure the safety of operators.

7. It has the function of temperature measurement display and system clock display.

8. Standard RS232 interface, can communicate with computer.
