1、 The principle of insulation oil dielectric strength tester
The dielectric strength tester for insulating oil tests the insulation strength of insulating oil by applying a high voltage. The principle is to insert two electrodes into the tested insulating oil separately, and then apply a high voltage. When the voltage reaches a certain value, the tested insulating oil will be broken down. At this time, the value of the voltage is recorded, which is the dielectric strength of the insulating oil. Usually, the tester will automatically stop applying voltage to avoid equipment damage caused by excessive voltage application.
2、 Application of Insulating Oil Dielectric Strength Tester
Quality control of insulation oil
In high-voltage power equipment, insulating oil is a very important part. The insulation performance of insulating oil is one of the key factors to ensure the normal operation and safety of equipment. The use of an insulation oil dielectric strength tester can detect changes in the insulation oil in a timely manner, so that corresponding treatment and replacement can be carried out to ensure the normal operation of the equipment.
Diagnostic equipment malfunction
When equipment malfunctions, the performance of the insulation oil is usually checked. By using an insulation oil dielectric strength tester, the condition of the insulation oil can be quickly and accurately understood, thereby determining the cause of equipment failure and taking corresponding repair measures.
Study the characteristics of insulation materials
In addition to measuring the dielectric strength of insulating oil, an insulating oil dielectric strength tester can also be used to study the characteristics of other insulating materials. For example, in the laboratory, different types of insulation materials can be inserted into the tester and a voltage can be applied to compare their dielectric strength. These experimental results contribute to the development of new insulation materials and the improvement of existing insulation materials.
3、 Maintenance of insulation oil dielectric strength tester
Regular calibration
The insulation oil dielectric strength tester needs to be calibrated regularly to ensure the accuracy of its measurement results. It is usually recommended to perform calibration at least once a year. When performing calibration, it is necessary to use standard capacitors or other standard devices to check whether the output of the tester matches the known values.
Keep clean
Before using an insulating oil dielectric strength tester, it is necessary to maintain cleanliness.
