which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment

The power transformer is designed according to the temperature protection scheme. The embedded parts in the material layer of high (low) pressure electromagnetic coil poured with integral concrete are provided with longitudinal ventilation duct, the output capacity can be increased by %.Power transformer manufacturerBayamo,The selection shall be carried out according to the load characteristics of power. There are many types of power loads. Different dry-type transformers shall be used for different power loads. If the standard impulse level of power load is less than kV, class H dry-type transformers shall be used. If the standard impulse level of power load exceeds kV, epoxy resin adhesive shall be used to pour dry-type transformers.The 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, it is necessary to ensure that this kind of conductor has sufficient insulation compressive strength, i.e. insulation spacing.Copiapo,Before application,BayamoPower transformer, the sampling container shall be cleaned with vehicle gasoline, soapy water or other organic solvents (such as trisodium phosphate) except oil stains, and then washed with tap water until it is not alkaline, and the water can be evenly distributed from the bottle, and then cleaned with purified water for many times. The cleaned sampling container shall be dried in a ℃ drying oven. After refrigeration, the bottle cap shall be tightly closed and cannot be opened before application.Careless maintenance and insulation damageWhen the new oil filled by the power transformer and the oil sample that has just been considered are used, 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,BayamoTransformer 10KV, the dispersion spacing and adverse effects are very large.How to select dry-type transformerFor example, in the s,BayamoOn load voltage regulation of power transformer, the radio programs applied by every family in the countryside had a ground wire, and they were often wet with tap water. Protective grounding is to bury the copper plate of metal electrical conductor in the soil layer, and then lead a point of it out of the road with transmission line, which completes the grounding protection. The grounding wire specifies the grounding wire resistance ≤ Ω. Grounding protection is a safeguard measure adopted to avoid safety accidents when using household appliances, office and other electrical equipment.quality,The power transformer conductor refers to the connecting transmission line between each electromagnetic coil, between the electromagnetic coil and the group outlet pipe, and between the electromagnetic coil and the tap changer.Plug in the power with full load first, observe and detect that the input and output voltage meets the regulations. At the same time, check whether the equipment has abnormal sound, odor and other abnormal conditions. If there is any abnormality, please cut off the input switching power supply.For the installation of lightning rod, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation, it is very easy to cause fire accidents, power failure, damage to machinery and equipment, etc.

Power transformers are used in all walks of lifeproperty right,The insulating layer in the middle of the silicon steel plate is aging, the anchor bolt cover with the iron core is damaged the iron core causes large vortex, resulting in heat, temperature rise, and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.The transformer manufacturer said that the selection should be based on the application environment of the dry-type transformer. For the extremely extreme environment, the dry-type transformer should be poured with epoxy resin glue. Because this kind of environment does not need to heat the dry-type transformer, it can operate immediately. However, for the general application environment, the class H dry-type transformer can be used.Therefore, in the operation prevention and regulation of relay protection dry-type transformer, it is necessary to find the short-circuit fault point according to the fault situation, and analyze the short-circuit fault types of relay protection dry-type transformer. At the same time, if all fields are clear, disconnect the switching power supply at the fault point, the maintenance work of employees will be carried out smoothly, and the harm will not expand to a greater extent.Bayamo,When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.After sampling, bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.Dry type transformer company
