Function and Application Fields
1. Power industry: Regularly inspect the insulation oil in large transformers and other oil filled electrical equipment in power plants, substations, and other places. Because the dielectric strength of insulating oil is directly related to the insulation performance of equipment, if the dielectric strength decreases, it may indicate the deterioration of oil quality or potential faults inside the equipment. Timely detection can ensure the safe and reliable operation of power equipment and avoid accidents such as power outages caused by insulation faults.
2. Petrochemical industry: Quality control is carried out on various insulation oil products during production and storage processes, to verify whether they meet the corresponding dielectric strength standards and ensure that product quality meets subsequent usage requirements, such as oil products used for electrical equipment lubrication, insulation, and other purposes.
3. Research and quality inspection institutions: Conduct research on the performance of insulation oil, or conduct quality supervision and testing on insulation oil from different sources and batches. Through methods such as dielectric strength testing, provide key data support for product development, quality assessment, etc.
Daily maintenance and upkeep
After the experiment is completed, promptly pour out the waste oil, clean the oil cup and dry it to avoid corrosion of the electrode.
Place the electrodes properly when not in use to prevent collisions and scratches on the working surface.
Regularly calibrate voltage and electrode spacing to ensure accurate measurement.
The instrument should be kept dry and ventilated, and if not in use for a long time, it should be regularly powered on to remove moisture.
LCD screens and keyboards should avoid being scratched by hard objects and should not be wiped with strong solvents.
Frequently Asked Questions
1. What factors can cause inaccurate results in the dielectric strength test of oil insulation oil?
Oil sample contamination before testing, unclean test cups, uncalibrated instruments, improper operation, etc. may all lead to result deviations.
2. What affects the measurement results of the dielectric strength tester for insulating oil?
In addition to the performance of the insulating oil itself, the temperature and humidity of the testing environment, the cleanliness of the testing electrodes, and the standardization of the operators will all have a certain impact on the measurement results.
3. Why does insulating oil deteriorate?
The deterioration of insulating oil is mainly due to the influence of high temperature, oxygen, moisture, metal catalysts and other factors during operation, resulting in chemical reactions such as oxidation and hydrolysis, leading to a decrease in oil performance.
4. Are there many types of dielectric strength testers for insulating oil on the market?
Yes, there are various types of testers on the market based on different needs and technical characteristics, such as fully automatic, semi-automatic, portable, etc.
5. Besides dielectric strength, what other important testing indicators are there for insulating oil?
In addition to dielectric strength, the moisture content, acid value, flash point, viscosity, density, and chromaticity of insulating oil are also very important detection indicators, which together reflect the comprehensive performance of insulating oil.
6. Where can I find a reliable dielectric strength tester for insulating oil?
You can consider manufacturers like Wuhan UHV Power Technology Co., Ltd., which have a good industry reputation and technical strength. Their products are usually guaranteed in terms of quality and after-sales service.
