Due to poor sealing, generally, it will lead to common faults of oil leakage.It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, porcelain, so as to achieve the pressure management of oil leakage.Nibai,The proper selection of Anhui dry-type transformer has a key effect on improving the safety and smooth operation of power system software. In the above original text, we have already mastered the structure and characteristics of dry-type transformer. In this part, we will describe how to select dry-type transformer according to the load characteristics and application environment of dry-type transformer.After no-load test run is normal for h, it can be transferred to on-load operation, and the load shall be gradually increased from %, % and % by grade.Canidelo,The sampling container is a colorless glass bottle with a wide mouth ground glass plug with a volume of .kg or kg. - bottles shall be collected at a time for analysis and experiment. Labels shall be attached during sampling. Pay attention to the name source,NibaiTypes of dry-type transformers,NibaiApplication of oil immersed transformer, sampling date, sampling person, weather conditions and other materials of the oil sample.Power transformers are used in all walks of lifeThe insulation distance between the winding and the iron yoke of power transformer is much larger than that between the windings, because the electric field between the winding and the iron yoke is far away and not as symmetrical as that between the windings. In the electric field in the middle of the winding, that is, the disconnection component of the electric field is small.

Brief introduction of zero line of power transformerThe proper selection of Anhui dry-type transformer has a key effect on improving the safety and smooth operation of power system software. In the above original text, we have already mastered the structure and characteristics of dry-type transformer. In this part, we will describe how to select dry-type transformer according to the load characteristics and application environment of dry-type transformer.The noise of dry-type transformer belongs to low-frequency noise. In a small area, most of it is scattered according to the building structure. This kind of low-frequency noise is scattered to the household house according to the house building, and then causes gas vibration noise, which is then scattered to the ears of consumers. Although the amount of noise is not very large,NibaiDry type transformer scb13-1250, the dispersion spacing and adverse effects are very large.analysis,Dry type transformerDry type transformer manufacturerThe vibration reduction of collecting and townhouse solves the soft connection of collecting and townhouse. For the copper bar of the low-voltage bus of the equipment, the electromagnetic induced noise oscillation may be transmitted from the townhouse to the building structure. The core of noise reduction solution must be changed to copper wire connection.

The flange surface is uneven, the tightening bolts are loose, and the installation and processing process is wrong, so that the bolts are not tightened well, resulting in oil leakage.How much does it cost?,Caused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.Transformer inspection nose sniffing methodPerformance and main parameters of common metal composites, various welding processes and machinery and equipment, preparation treatment of thick steel plate, blanking process, production and manufacturing process and quality standards of automobile oil tank, riser, coupling and oil storage tank cabinet, welding leakage test and NDT technology, surface treatment process and quality standards, copper, Production process and quality standard of aluminum shield; Body suit iron insertion process, wire installation process, body dryness solution and dry transformer oil solution process, vacuum pump oil immersion, general installation process, leakage test and leakage detection process and quality standards. Performance parameters of key work clothes machinery and equipment of each process flow; The natural working environment is basically regulated.Nibai,The representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side), and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring, and D (or D) is triangular wiring.Before no-load impact closing the pose period of overcurrent protection shall be set to zero, and the data signal circuit of steam vehicle relay shall be temporarily connected to the pull-in circuit.Sound in case of phase failure
