What issues should be noted in transformer insulation oil testing? How to ensure the safety of insulation oil testing?

:2024-03-26 15:53:17:

The insulation oil test of transformers should pay attention to the following issues:

① Preparation before the experiment:

The test oil should be stirred evenly without impurities, and the temperature and environmental humidity of the test oil should meet the test requirements.

② Equipment inspection:

Before the experiment, the testing equipment and testing instruments should be inspected and repaired to ensure their normal operation.

③ Experimental operation:

During the experiment, strict monitoring of the testing equipment and instruments should be carried out to ensure the accuracy of the test data.

④ Safety precautions:

During the testing process, relevant safety regulations and operating procedures should be strictly followed to ensure the safety of the testing personnel.

⑤ Post test treatment:

After the experiment, the testing equipment should be cleaned and disinfected in a timely manner, and necessary maintenance and upkeep should be carried out.

In addition, the transformer insulation oil test should also pay attention to the fact that before the testing personnel come into contact with the equipment, they should fully discharge the tested equipment and disconnect all connections between the tested equipment and the outside world.

To ensure the safety of insulation oil testing, the following measures can be taken:

① Preparation before the experiment:

Flammable materials are prohibited to be stacked around the testing device to ensure good ventilation conditions at the testing site and avoid oil and gas accumulation.

② Experimental operation:

Test personnel should undergo professional training and assessment to obtain corresponding qualification certificates. Necessary personal protective equipment should be equipped during the experiment, such as safety helmets, protective goggles, anti-static clothing, protective gloves, etc. The power supply of the testing equipment must comply with safety standards and undergo regular testing and maintenance.

③ Post test treatment:

After the experiment is completed, the testing device should be cleaned to ensure that there is no leakage or accumulation of insulation oil, and the working condition of the testing equipment and instruments should be checked. If there are any abnormalities, they should be repaired or replaced in a timely manner.
