What is the wavelength of oil immersed transformer?Power transformer is an idealized supporting facility transformer for medium cabinet and high-voltage cabinet at the present stage, and can be equipped with safety protective casing according to different waterproof grades. It is applicable to key or unique natural environment sites such as multi-storey buildings, airports, tunnel construction, chemical enterprises and factories.Perme,PermeAmerican box transformer,Precautions for trial operation of power transformer manufacturersThere are many connection groups of dry-type transformers, and the selected structures and connections are also different. Then, what are the groups of dry-type transformers? How to carry out the connection? Or basically introduce it with the network of dry-type transformer manufacturers.Gojra,Fault judgment of power transformerOil immersed transformer companyOutdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling, it is necessary to resolutely prevent the invasion of dirt such as rain, snow wind and sand.

Brief introduction of zero line of power transformerIt is understood that in China,Perme220 kV Transformer, transformers have experienced the whole process of replacing many series products such as sss. As early as the middle and late s, S Series lossless distribution transformers were selected in China to replace the high energy consumption transformers of jb- and jb - Specifications operating in the power network at that time. Since the th century, urban power grids have been transformed all over the country, and S series distribution transformers have been used to replace S Series. In recent years, S and S commodities are gradually selected in large quantities in the transformation of urban and rural power networks in China, and their full load loss is % - % less than that of S transformer.& ldquo; of wiring transformer; Enter & rdquo; And & ldquo; Output & rdquo; Use a megger to test the grounding resistance between the terminal and the ground wire. When accurately measured by V megger, the resistance value exceeds m ohm bus.Honest service,Power transformer factoryThe 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.Sound in case of phase failure

The method and whole process of taking oil sample of power transformer are as follows:Analysis project,Analysis of common faults of oil immersed transformer:The transformer manufacturer will introduce the efficiency of the transformer to youThe conductor insulation of power transformer is the main part of internal insulation. Some conductors should pass through the middle of electromagnetic coil, or between electromagnetic coil iron yoke clamp and automobile oil tank wall. Therefore,PermeInspection items of dry-type transformer, it is necessary to ensure that this kind of conductor has sufficient insulation compressive strength, i.e. insulation spacing.Perme,The noise of dry-type transformer comes fromIf the above provisions are not met, 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 N 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.Dry type transformer
