The specific operation method of the insulating oil dielectric strength tester is as follows:

1. Test operation process.

When using the insulating oil dielectric strength tester for testing, you need to follow the following process:

1) Ground the instrument reliably;

2) In the power-off state, place the magnon in the oil test cup;

3) The oil test must be placed in the test room for a period of time without destroying the original storage seal, and the cover can be uncovered after the oil temperature and room temperature are similar. Before removing the lid, gently shake the test oil to make the internal impurities uniform, but not to produce bubbles, before the test, wash the oil cup with the test oil 2 3 times;

4) In the power-off state, when the test sample oil is loaded into the oil cup to test the oil and inject into the oil cup, it should slowly flow down along the inner wall of the oil cup to reduce bubbles. After the test oil is full, it must stand for 10 to 15 minutes before the pressure increase test can begin;

5) In the power-off state, cover the electrode hood and cover the high-voltage chamber;

6) Close the power switch, and the instrument will automatically turn to the main interface after the welcome interface appears;

7) By rotating the mouse, you can choose to perform breakdown test, withstand voltage test, view historical data, time setting, PC communication and other operation items.

2. Breakdown test.

After entering the breakdown test, the instrument display can view the interface shown in the manual.

The operation method of the breakdown test is as follows:

1) Set the test parameters, the set items include, oil mark, initial standing time, test times, standing time and stirring time, the initial standing time range is 0 seconds 9 minutes 59 seconds, the setting range of the standing time is 0 seconds 9 minutes 59 seconds, and the setting range of stirring time is 0 seconds 59 seconds.

2) Select to start the test, click to run, the instrument will be cycled in the order of first boosting to breakdown, stirring, standing, and then boosting to breakdown, until the set number of tests is reached, the buzzer will chirp, and the test will stop.

3) After the breakdown test is completed, the display of the instrument can be viewed in the manual, and the test results displayed include the breakdown voltage, the average breakdown voltage and the test parameter settings.

4) The operator can also save and print the test results as needed.

Insulating oil dielectric strength tester, insulating oil is widely used in transformers, oil circuit breakers, oil-filled cables, power capacitors and oil bushings and other high-voltage electrical equipment. In operation, the performance of the insulating oil will gradually deteriorate due to the action of oxygen, high temperature, high humidity, sunlight, strong electric field and impurities, so that it can not give full play to the insulating role. The quality of the insulating oil is closely related to the breakdown voltage.

In accordance with the requirements of the International Electrotechnical Commission standard IEC156 "Insulating Oil Dielectric Strength Test Method" and the national standard GB507-86, the XGIIJ-80KV microcomputer automatic insulating oil dielectric strength tester was designed on the basis of fully considering the needs of domestic and foreign users.

Insulating oil dielectric strength tester is in accordance with the requirements of the International Electrotechnical Commission standard International IEC-156 and the national standard GB507-86 "Insulating Oil Dielectric Strength Determination Method", fully considering the needs of users at home and abroad and the research and development of a new generation of automatic oil tester. The operation is divided into fully automatic six times and fully automatic single operation, with automatic boost test, automatic stirring, automatic processing, automatic printing and digital display and locking technology, etc., the reading is intuitive, the measurement is accurate, and the test process is safe and reliable.

The automatic insulating oil dielectric strength tester adds the function that the perpetual calendar and experimental data can be saved for a long time, and the digital display is changed to liquid crystal display. The controller adopts a single-chip microcomputer to test the whole process, and the anti-interference performance is particularly strong, which completely overcomes the shortcomings of the current liquid crystal automatic tester that it is susceptible to high-voltage breakdown interference. It not only has the ability to improve work efficiency and make monotonous, repetitive, and boring work quite meaningful, but also safe, reliable, and accurate measurement.

This instrument is simple to operate: except for the first time you need to press the preset to the data you need (if you measure according to the national standard, this step can be saved, because the data has been preset according to the national standard when leaving the factory.) The number of times is 6 times, the stirring time is 1 minute, and the standing time is 5 minutes).

The diversity of operating methods is designed for the different needs of users.

Measuring the dielectric strength of insulating oil, whether there are bubbles, impurities, etc., is generally used in the regular maintenance of large transformers.

1) Preparation of insulating oil dielectric strength tester.

1. The power supply is single-phase alternating current 220V, and the grounding terminal of the shell must be connected to a standard ground wire.

2. Carefully install and check the oil cup, and pay attention to the axis of the two electrodes. Adjust the electrode spacing to a small plate: , and the rest are.

3. Close the power switch, the power indicator light is on, and the voltmeter display indicates that the machine is working normally. (It is normal to display a few word errors, which does not affect the test accuracy).

4. Before the pressure is boosted, the pressure must be lowered first, and then the pressure boost calendar guessing test must be made, otherwise the action will be refused.

2) Testing. 1. The insulating oil dielectric strength tester slowly injects the prepared oil sample into the oil cup, cleans it twice, then fills the oil sample and places the oil cup in the electrode frame, closes the oil cup cover, and presses the interlock switch (if the oil cup cover is not closed, it will refuse to act).

2. Let stand for 10-15 minutes to remove air bubbles.

3. When the oil breaks down, the overcurrent protection relay and the protection system device act to cut off the power supply of the booster within seconds, and the digital display is the breakdown voltage value of the oil.

4. The insulating oil dielectric strength tester pushes the step-down switch, and the voltage regulator automatically returns to zero, and the second test of the remaining limb can be done after five minutes.

5. During the test, if the voltage of the external line is insufficient, although the digital display is not up to 80kV, the voltage regulator turntable has touched the limit switch.

6. During the test, if there is an abnormal situation, you can press the stop switch to force the high-voltage power supply to be cut off (when the test is retested, the stop switch is reset).
