In the power system and factories and mines, enterprises have a large number of electrical equipment, its internal insulation is oil-filled insulation. The dielectric strength test of insulating oil is a routine test. In order to meet the needs of the rapid development of the power industry in the original series of automatic insulation oil dielectric strength tester based on the introduction of its improved and strengthened version, the new version of insulation oil dielectric strength tester increased the standard and method selection and other content, simplified the user's operation, convenient for users to apply different conditions of use. This product is designed and manufactured according to the new test procedure DL/T 596-2005 and the corresponding national standard GB/T 507-2002 and DL/T 429.9-91. It adopts micro-chip computer control, integrates mechanical and electrical automation, has high measurement accuracy, improves work efficiency, and also reduces the labor intensity of staff.

Function introduction
1, the series of instruments for the integrated structure, according to different models can continuously test the corresponding number of cups of oil samples. The instrument is controlled by a micro-chip computer, which can automatically complete a series of operations such as static discharge, pressure boost, stirring, calculating average value, displaying data, storing data, printing, and measuring the temperature and humidity at that time. Oil pressure cycle test can be carried out in the range of 0-80kV.

2, using 800×480 large screen color touch screen LCD display, internal backlight system can be clearly visible even at night. Built-in 13 kinds of test standards and 6 test methods and self-determined parameters for testers to choose and set, testers can choose the appropriate test method according to the actual situation. The thermal printer is used for good printing effect and low noise.

3, the instrument is simple to operate, the operator only need to enter simple instructions according to the instructions, the instrument will automatically complete the voltage test according to the set parameters. Each breakdown voltage value is automatically stored, after the test is completed, the printer can print out each breakdown voltage value and average value of each oil cup.

4, the instrument has strong adaptability, can be used in the laboratory and outdoor field, the instrument also has anti-interference ability, can also work normally in the strong electromagnetic field environment. It is suitable for departments with many oil samples and tight test time requirements.

5, the instrument has overvoltage, overcurrent, limit and other protective devices, in the normal use of the environment, absolutely ensure the safety of the instrument itself and the operator.

6, the instrument has 10 kinds of boost speed can be selected according to different test requirements.
