Product introduction
The Oil Dielectric Strength BDV Tester (single cup) is one of the most critical specialized equipment used in the power industry to evaluate the electrical insulation performance of insulation oils such as transformer oil, cable oil, and capacitor oil. It accurately measures the breakdown voltage of insulating oil through highly automated processes such as oil injection, settling, stirring, boosting, detection, recording, and oil discharge, effectively evaluating the insulation performance of oil products
Core Function & Purpose
Measure Insulating Strength: Accurately determines the highest voltage (typically expressed in kV) that insulating oil can withstand under standard test conditions without breaking down. This value is called the dielectric strength or breakdown voltage.
Assess Oil Quality: Breakdown voltage is a crucial indicator reflecting the purity, dryness, and presence of contaminants (such as moisture, fibers, carbon particles, etc.) in insulating oil. Degraded oil quality significantly reduces its breakdown voltage.
Ensure Equipment Safety: Regularly testing the dielectric strength of oil in oil-filled electrical equipment like transformers is a key preventive maintenance task to prevent internal insulation failures and ensure the safe and stable operation of power systems.
matters needing attention
1. Before using this fully automatic insulation oil dielectric strength tester, be sure to read the operation manual carefully.
2. The instrument operator should be familiar with the general usage knowledge of electrical equipment or analytical instruments.
3. This insulation oil dielectric strength tester can be used both indoors and outdoors, but should be avoided from places such as rain, corrosive gases, high concentrations of dust, high temperatures, or direct sunlight.
4. The oil cup should be kept clean. During the shutdown period, a sufficient amount of dry and qualified insulating oil should be added to soak the oil cup to prevent moisture and electrode oxidation.
5. After one month of continuous use, the electrode should undergo routine inspection and maintenance. Check and adjust the electrode gap to restore it to the standard value; Use a magnifying glass to observe whether there are dark spots on the surface of the electrode. If this phenomenon occurs, use a silk cloth to wipe the surface of the electrode to restore it to its original state.
6. The maintenance and debugging of instruments must be carried out by professionals.
7. Before connecting the power supply, carefully check whether the connecting wires are secure and the instrument casing must be reliably grounded!
8. After connecting the power supply, operators are strictly prohibited from touching the outer shell of the oil cup box cover to avoid danger!
9. If any abnormalities are found during the use of the instrument, the power should be cut off immediately!
