Kutaisi.How to make up oil for oil immersed transformer?
The cross-sectional wiring of transformer input and output power plugs shall comply with the provisions of their current size; It should be equipped according to the current intensity of 2-5A / Min2.
.The voltage regulating tap changer is not in place or poor
The project cost is different. Compared with the purchase price of capacity transformer,KutaisiOil immersed main transformer, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.
The method and whole process of taking oil sample of power transformer are as follows:
For 630kVA power engineering transformer, China's first UHV transmission experimental demonstration project, China Transformer Corporation has entered a breakthrough in the development trend. The commodity voltage grade and volume rank first in the world, occupying the main technical position of the industry development trend. In addition, it has promoted the continuous improvement and perfection of the technology of low-voltage transformers.
The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts, with good strength and stiffness, which is conducive to adjusting the data and has a unique and neat style.
market.When the manufacturer of the power transformer samples from the automobile oil tank after opening the sealing cover,KutaisiPower supply transformer manufacturer, use the cleaned and dried rubber stopper to the oil. At the same time, clamp the branch pipe with your thumb, and loosen your thumb to make the oil enter the pipe,
The raw materials of Fushi blue can be used for bonding, so that the overall oil leakage of the connector can be greatly controlled; If the actual operation is convenient, the metal shell can also be bonded at the same time to achieve the purpose of leakage treatment.
Operation of oil immersed transformer
For no-load impulse closing of transformer, pay attention to the following matters:
Potential development.Oil leakage at looper flange
Protection mode for type selection of dry-type test transformer
If the above provisions are not met, the problem of dryness shall be solved. Generally, it is OK to operate the centrifugal fan for a period of time. Check the cleanliness of the power transformer. If too much dust is found, it must be eliminated to ensure indoor ventilation and avoid insulation penetration. In particular, pay attention to cleaning the insulators of the power transformer and the top and bottom ends of winding resistance installation. Portable centrifugal fan or dry air compression or N2 shall be used to clean the dust in indoor space that is not easy to reach such as ventilation duct, and there shall be no dirt.
