Portable and Convenient The RDJDH-100kV Tester is designed with a portable structure, making it easy to move and suitable for both indoor and outdoor use. This flexibility allows for efficient testing in various environments and conditions.In the transformer, oil circuit breaker, oil-filled cables, power capacitors and oil casing and other high-voltage electrical equipment operation, insulating oil due to oxygen, high temperature, high humidity, sunlight, strong electric field and the role of impurities, the performance of the gradual deterioration of the insulating effect it can not give full play to this must be carried out on a regular basis for the test of the insulating oil in order to identify the performance of whether or not to deteriorate. The quality of insulating oil and breakdown voltage has a close relationship.
Breakdown voltage is a measure of the medium to withstand the voltage and not be destroyed ability, is to test the transformer oil performance is good or bad one of the main indicators, dry and clean oil has a fairly high value of the breakdown voltage. Influence transformer oil breakdown voltage of the main factors are water, impurities, temperature, temperature on the breakdown voltage relationship is more complex, dry, no impurities in the oil, the breakdown voltage is by the oil neutral particles of the not free to maintain.
But when the oil contains free water, dissolved water or solid pollutants, because these impurities have a larger conductivity and dielectric constant than the oil itself, they will constitute a conductive bridge under the action of the electric field and reduce the breakdown voltage of the oil. Dielectric strength of insulating oil tester can determine the oil, whether there is water, impurities and conductive particles, but it can not determine whether the oil is acidic or sludge. General transformer oil after vacuum filtration and degassing to join the transformer before the breakdown voltage can reach 70KV. insulating oil is an important dielectric material in electric power and industrial production, is widely used in transformers and other electrical equipment, play a role in cooling and insulation.
