Vacuum transformer oil filter device
Have been tested by us for 7 years to be the most cost-effectirve among different modles of Vacuum oil filter device. We can help you to derease the risk of transformer manufacturing equipment selection, especially for a new transformer factory. |
Descriptions
There are great hazards, which are described as follows:
1. Reduce the breakdown voltage of the oil. The water content in the insulating oil is the main reason that affects the breakdown voltage reduction.
2. It will increase the dielectric loss factor. Because the presence of water in the oil is different, the influence on the dielectric loss factor is also different. The suspended emulsified water will increase the dielectric loss of the oil most obviously. Corrosion products of water, such as
Naphthenic acid soaps are very easy to worsen the dielectric loss and will sharply increase the dielectric loss, which is the indirect result of moisture affecting the dielectric loss
Fruit.
3. Make the insulating fiber easy to age and increase its dielectric loss.
4. Water promotes the corrosion ability of organic acids and accelerates the corrosion of metal parts. Metal corrosion products
Metal soaps, for example, will promote the rapid aging of oil, that is, play a catalytic role in oil aging,
To sum up, the more water content in the oil, the aging of the oil itself, the aging of equipment insulation and the corrosion of metal parts
The faster the corrosion rate is, it will affect the safe operation of the equipment and shorten the service life of the equipment.
